Q: Can Magic C++ support GDB for embedded targets like PowerPC?
A:
Yes.
Magic C++'s server component is OPEN SOURCE that means you can compile and install it under any Linux/BSD/Unix OS. For your instance you need compile the server source codes under the PowerPC Linux, once you finish this phase you can use Magic C++ to develop.
If your PowerPC Linux is the embedded target board instead of the cross-development host computer, it may runs short of resources include memory and disk space and the integrated GNU development toolchains will cost too much to use, for this situation you can choose gdbserver to reduce the resources cost.
Magic C++ supports for GNU cross development toolchains. Screenshot

Q: While creating or opening a project over SSH/SFTP connections, it reports 'Install Magic C++ Remote tools failed! Please install them manually.' or 'Query Magic C++ Remote Tools failed!', what to do?
A:
Magic C++ v3.5 or higher supports for SSH/SFTP secure development environment as a plus to TELNET/FTP traditional development environment. You need manually install the server component of Magic C++( server side daemon, magicd ) on Unix/Linux/BSD servers under TELNET/FTP traditional development environment, but this phase is not necessary for SSH/SFTP secure development environment, it's replaced by Magic C++ remote tools( server side command line tools for text search/replace etc. ) which will be installed automatically, much easier to install and use.
Generally Magic C++ remote tools will be installed automatically, if it fails
please send us the debugging log file
C:\Program Files\MagicUnix\Magic C++\log\remote_tools.log
and
C:\Program Files\MagicUnix\Magic C++\log\dup.log
we'll check the problem for you. You can also follow these steps to install it manually:
(1)get home directory of your account on linux server
==========================
[ken@linux90 ken]$ echo $HOME
/home/ken
[ken@linux90 ken]$
==========================
(2)transfer the source code tar package to the home directory via FTP/SFTP
put C:\Program Files\MagicUnix\Magic C++\src\.magic_cpp.tar /home/ken
(3)untar the source code tar package
tar -xvf .magic_cpp.tar
(4)change direcoty
cd .magic_cpp/src
(5)compile the source codes with your compiler

Q: How to startup the server component automatically while the server system boot up?
A:
For Linux server OS:
Please append this statement at the end of file /etc/rc.d/rc.local
/path/to/magicd-3.0.0/bin/magicd
( replace /path/to by your installation directory of magicd )
For Sun Solaris:
1. change directory to /etc/rc3.d
#cd /etc/rc3.d
# pwd
/etc/rc3.d
# ls
README S16boot.server S76snmpdx S84appserv
S13kdc.master S34dhcp S77dmi S89sshd
S14kdc S50apache S80mipagent S90samba
S15nfs.server S52imq S81volmgt
the filename format of services is like S**service where ** is a digital ID( S means Startup )
2. create a startup profile for magicd with ID 91
#vi S91magicd
and input content as below:
#!/bin/sh
/path/to/magicd-3.0.0/bin/magicd
( replace /path/to by your installation directory of magicd )
3. change file permission
#chmod 755 S91magicd
4. reboot the system and check the magicd process
#ps -ef|grep magicd
root 330 1 0 22:18:53 ? 0:00 /home/test/magicd-2.5.0/bin/magic
d
test 480 359 0 22:25:05 pts/2 0:00 grep magicd
Other server OS:
Please refer their system administrator manuals.
Q: When initiating debugger got the error message 'Enum updated file failed', what to do?
A:
If you use bash shell please make sure the environment variable called PROMPT_COMMAND must be empty. Restartup magicd to take effect.
Typical environment variables look like:
==============
BASH=/bin/bash
PROMPT_COMMAND=
PS1='[\u@\h \W]\$ '
=============
This problem can also be caused by abnormal command prompt of your Unix/Linux shell environment.
The proper command prompt is like this:
[mc@linux90 mc]#
Magic C++ doesn't support these command prompts:
(1)command prompt is multi-line texts which including a newline character.
(2)command prompt is colorful texts
(3)command prompt contains a counter for commands or time information, so it will change after command executing, for example
"Tue Aug 09 19:34:31 root#"
(4)command prompt is empty
Magic C++ can't work normally with these above command prompts. Please reconfigure command prompt as proper format with Magic C++ supports by add command in the shell profile of your account as below:
set prompt="new_cmd_prompt" ( for csh )
set PS1="new_cmd_prompt" ( for bash, sh )
This problem can also be caused by abnormally startup of magicd, the server component of Magic C++.
Please notice:
(1) Do not startup magicd from terminal window at x-windows desktop.
(2) Do not startup magicd by putty.exe via SSH protocol. Please startup magicd by cmd.exe which provides by windows or other tools via TELNET protocol. If you can only use SSH connection please use SSH tools other than putty.exe.

Q: While initiating debugger got error message ' Starting debug redirection terminal...failed!', how to solve this problem?
A:
This problem may be caused by abnormal command prompt of your Unix/Linux shell environment. Please refer here for more information.
Abnormal command prompt which Magic C++ doesn't support.
If it doesn't help to solve the problem, to help us better investigate into the problem, please follow instructions below:
(1) stop magicd by commands:
# cd /your_magicd_install_path/bin
# ./killit.sh
(2) empty the log file log/dup.log
(3)startup magicd in debugging mode to print debugging info in details to the log file, that will help us to solve problems for you.
# ./magicd --debug
(4)
telnet to port 2004(magicd working port) manually and test login operation
(5)
On the Magic C++ client, be sure to set the server properties correctly to reflect the port change to 2004(magicd working port).
1. Open the Remote Server Manager (under file menu) File->Remote Server Manager.
2. Open the Server Property dialog for your server.
3. Under the "Advance" tab* , set your Telnet port to 2004(magicd working port) instead of 23(the standard telnet port).
***NOTICE***
But there is one exception.If you have installed the server component(RDA) without superuser privilege and active the authentication ability provides by Magic C++, at this situation you must specify the telnet port of redirection terminal corresponding to the server component(RDA)(default is 2004).
Execute the debug operation, if it invokes error messages, please send us the log/dup.log file and we'll try to solve this problem for you as soon as we can.

Q: I have downloaded Magic C++ and the editor works well, but it always fails when I tryto start debugger, it tells me "start debugger error" after I choose the menu item
"Compile->Debug->Go".
A:
Please check the output messages of "View->Output->Debug tab page" on the bottom of Magic C++ IDE, if you find messages like these:
======================================
Starting debugger...OK.
Starting debug redirection terminal...failed!
============================
please refer here to solve this problem
'Starting debug redirection terminal...failed!', how to solve this problem?
There are also other possible reasons for this problem:
(1)the remote telnet server works abnormally( if you have specified port 23 as the telnet port of redirection terminal instead of port 2004 )
(2)the maximum number of telnet connections for the user acount has reached ( if you have specified port 23 as the telnet port of redirection terminal instead of port 2004 )
(3)the network is too busy to establish a connection before timeout
(4)some user account such as root maybe not allow to login remotely
If these doesn't help to solve the problem, to help us better investigate into the problem, please follow instructions below:
(1) stop magicd by commands:
# cd /your_magicd_install_path/bin
# ./killit.sh
(2) empty the log file log/dup.log
(3)startup magicd in debugging mode to print debugging info in details to the log file, that will help us to solve problems for you.
# ./magicd --debug
Execute the debug operation, if it invokes error messages, please send us the log/dup.log file and we'll try to solve this problem for you as soon as we can.

Q: How to set the idle timeout option of server to avoid being disconnected?
A:
Modify the file named /etc/default/login as below:
# TIMEOUT sets the number of seconds (between 0 and 900) to wait before
# abandoning a login session.
#
#TIMEOUT=300
Active login sessions will not be effected until reconnect.

Q: Can I use Magic C++ with SSH and SFTP connection?
A:
Magic C++ v3.0 and lower version don't support for SSH and SFTP, these features are implemented in Magic C++ v3.5 and higher version.
Magic C++ v3.0 and lower version need a server side daemon program ( magicd ), use FTP to transfer files between local machine and remote servers, you need install ftp server package ( wu-ftp, vsftp etc. ) on remote server before using Magic C++. Once the server supports FTP connection then you can use Magic C++ even without TELNET support, because Magic C++ has implemented TELNET protocol itself. Please check the advanced property sheet of the remote server, and you must specify the telnet port of redirection terminal corresponding to the server component(RDA)(default is 2004) to use TELNET protocol provided by Magic C++.
Magic C++ v3.5 and higher version support SSH/SFTP as a plus, can use SFTP to transfer files between local machine and remote servers, you need install SSH/SFTP server package ( OpenSSH etc. ) on remote server before using Magic C++. Once the server supports SSH/SFTP connection then you can use Magic C++ without any server side daemon( magicd ), much easy to install.

Q: How to debug a console application that uses a shared object library?I'm trying to debug a console application that uses a shared object library. The shared object library was compile with debug option -g and compiled outside of Magic C++.
I compile and link my console application using -L<library path> -l<libname> which uses my shared object library. The console application is built with Magic C++. Note that the shared object library was not compile with Magic C++ but using a custom makefile.
When I debug the console application using Magic C++, and step into a function that is contained in the shared object library, I get prompted with a open file dialog so that I can browse to the location of the source file. Apparently, Magic C++ does not know the location of the file. If I browse and open the file, I can continue debugging from within Magic C++.
However, if I debug the same console application compiled and linked outside of Magic C++ using gdb on the target system, and step into the function contained in the shared object library, I am able to without having to browse for the file.
Is there any way to tell Magic C++ where the base directory or source files of the shared object library are so that I can seemlessly step into functions contained within it without having to browse to each source file?
A:
Please add shared object library project to the same workspace with your console application. That means put these two projects in one workspace then Magic C++ can automatically detecte of source file location.

Q: I am testing Magic C++ Enterprise Edition 3.0 build 050627. It worked
well last week. Last Friday I shutdown both the client and the server
machines. This morning I turned it on. Then after I loaded a project
and built it, all the menu items under the Compile are grayed except
the Stop Build and Debug. I have reinstalled the client side. It still
doesn't work. What's the solution?
A:
This issue can be solved by starting magicd from telnet on Windows. Open a command line window by cmd.exe and execute telnet command in it, then startup magicd.

Q: While compiling Magic C++ reports error message 'change current working directory failed!', what to do?
A:
The ftp server should permit the user switch to the root directory / to execute file operations via ftp protocol. Some ftp servers don't support this feature defaultly and need reconfigure this option.
Here is a ftp session to demonstrate this feature:
==========================
230 User magiccpp logged in.
ftp> pwd
257 "/home/magiccpp" is current directory.
ftp> cd /
250 CWD command successful.
ftp> pwd
257 "/" is current directory.
ftp>
==========================
look, although the home directory of user 'magiccpp' is /home/magiccpp magiccpp can still change directory to / and execute file operations. Magic C++ can work well under this situation.
***NOTICE***
Magic C++ can work well while the root directory via telnet protocol is same with the root directory of ftp protocol, and has nothing to do with the home directory of user.
To verify it you can just login to the server via telnet and ftp protocols, execute 'cd /' command to check it.
For Magic C++ v3.5 or higher users, please use this tip to solve this problem:
use regedit.exe to open and edit the windows registry,
search HKEY_CURRENT_USER\Software\Magic C Enterprise Edition\Servers and find the server entry,
create a STRING type subkey named with "FilePath Prefix" and set value to /
create a STRING type subkey named with "CmdPath Prefix" and set value to /home/magiccpp/
create a DWORD type subkey named with "Path Convert Type" and set value to 1
with these 3 subkeys Magic C++ will convert the path automatically and solve this problem without changing the server configuration.

Q: How does Magic C++ do compiling and debugging?
A:
Magic C++ provides remote compiling and debugging functions, but doesn't provide compileror debugger itself.Rather, through RDP( Remote Development Protocol), Magic C++ seamlessly integrates with all major unix/linux server compilers and debuggers to accomplish these tasks.
Here's a brief introduction about Magic C++'s remote debugging mechanisms.
By integrating support for both FTP, TELNET and our custom Remote Development Protocol(RDP) based on a client/server architecture, Magic C++ presents a seamless interface to opening and editing files, and executing remote commands still using existing remote server-based compilers and debuggers(i.e. gdb or dbx) to compile and debug.
Magic C++'s full installation consists of two phases. One for the server component - RDA( Remote Development Agent ), and one for the client component C/C++ IDE( Integrated Development Environment ). Without RDA installed IDE can ONLY work under edit mode and without support for remote compiling and debugging.
The server component - RDA( Remote Development Agent ) is an extended telnet server which works based on TELNET protocol and implements some extended IAC commands for executing remote commands.
Here is a typical scene for executing remote commands
1)the developer executes a debug command in Magic C++ IDE, such as clicking a menu item
2)Magic C++ IDE converts the operation to debugging command
3)Magic C++ IDE sends the command to RDA via network socket
4)RDA receives and executes the command
5)RDA redirects the output info to Magic C++ IDE as soon as it receives from the terminal
6)Magic C++ IDE parses the output info and refreshes all relative GUI elements's status

Q: I'm concerned about the performance of remote compiling and debugging over telnet/ftp, how is the speed of Magic C++?
A:
Over all Magic C++ provides superb performance even when working remotely.
Please note that if you're connecting via telnet for the first time, because of the delay in logging into the remote server, it would appear to be slow, however all remote operations thereafter will be at decent speeds.
To reduce the delay of opening files, when you first open your remote project, mirror files will be built locally. When you open the same project again, Magic C++ will check for updates first. If the file hasn't been modified, Magic C++ will read from the local mirror and thus reducing delays in file opening.
To reduce the delay of debugging task, you can disable automatical refresh feature of unnecessary debugging information windows include 'Watch Window', 'Call Stack Window', 'Memory Window' etc. by configuring 'Tools/Options.../Debugger Settings'.
Magic C++ 3.5 or higher also supports SSH/SFTP environment as a plus.

Q: Sometimes code aware such as auto completion, members list can't work.
A:
(1) The declaration is incorrect.
for example:
class CTest
{
// ...
};
class CMain
{
int funcA();
};
int CMain::funcB()
{
CTest a;
a.
// Auto completion and member list can't work because funcB has no declaration.
}
(2) There are errors in your codes.
for example:
int CMain::funcA()
{
CTest a
....
a.
// Auto completion and member list can't work due to fatal error, there's no semicolon after statement "CTest a".
}

Q: What does 'offline edit' mean?
A:
This function is called 'Offline editing' in Magic C++, that is you can edit your source codes locally without connecting to the Unix/Linux/BSD server, then while needed you can force upload the source codes to Unix/Linux/BSD server to compile and debug.
To use this function, select 'Files' tab in 'Workspace' view, right click the project then select 'offline' menuitem, then you can edit the source codes locally.

Q: I am able to successfully compile with the remote workspace setup. But when I hit 'Execute' it waits pops the 'Logining and executing program...' windows and waits for sometime, then it pops up a windows which says 'Execute failed', what to do?
A:
To solve this problem, we need the debugging log file of magicd( the server component ). Please generate and send it to us, here are the steps:
(1) change working directory
# cd /your/path/magicd-3.0.0/bin
(2) stop active magicd process
# ./killit.sh
(3) restart magicd in debug mode to generate debugging log file
# ./magicd --debug
(4) execute operations in Magic C++ IDE( the client component )
(5) get the debugging log file
/your/path/magicd-3.0.0/log/dup.log

Q: Can I specify a directory on windows client to back up my source files on remote Unix/Linux/BSD server?
A:
You can find a source codes copy in this directory
Drive:\Program Files\MagicUnix\Magic C++\MirrorFiles
And the structure of source codes is same with the server file system.
They are used as a cache to speed up Magic C++.

Q: Can I use another CVS, like ClearCase or VSS?
A:
Yes. ClearCase plug-in for Microsoft Visual Studio was designed primarily for use with MS Visual Studio, but in principle it can be used with any IDE that supports Microsoft's SCC API. Magic C++ Advanced Enterprise Edition 4.0 has implementated Microsoft SCC API, so any source control plug-in for Microsoft Visual Studio include ClearCase, VSS etc. can be reused in Magic C++ without any modifications.
