Remote compilation and debugging with QDE
Hello,
we have a system with a Windows host and a QNX target. Currently, we understand that QDE supports cross compilation on
the Windows host, in which the binaries are then transferred to the QNX target for execution and remote debug (with help
of qconn). We understand that in our setup, compilation for the QNX target happens on Windows, ie. cross compilation.
Is it possible to setup QDE to perform a remote compilation instead? Here, we would trigger some makefiles on the QNX
target file system for compilation. Simplistically, this could be done with a simple ssh command. However, then we would
lose the QDE integration into code development, compilation error tracking and remote debugging ... in short all QDE
benefits.
We much prefer remote compilation as we are trying to avoid the effort of maintaining a makefile structure + libraries +
generation executables (IDL compiler).
Hence, is there anyway QDE's mechanism can be changed from cross compilation to remote compilation?
Thanks a lot for your help already in advance

Re: Remote compilation and debugging with QDE
Nothing really out of the box. You can mount the sources from target to PC and use same sources and generated artifacts,
but you would have to setup "source mapping"
so debugger and other tools find your code. If you use ssh you not necessary going to loose error parsers, if your ssh
runs from the IDE build and output error
on the console IDE would still parse it.
It may be a CDT extensions that does remote builds, but you would have to look it up yourself, and I am not sure it will
work with qnx.
Internally we use recursive makefiles which runs almost the same on windows, linux and qnx, so porting is not a big
issue (but we use qcc/gcc)

Re: Remote compilation and debugging with QDE
Thanks a lot for your response
I tried to follows the steps that you have mentioned, but have few doubts regarding them,
It woule be great if you can clarify those
A) Source Mount :
In here you mean, that I manually copy the files from the target system viewew to workspace ?
Is there a way that i can autmote this , so that I dont need to copy the files on the HOST (WIN)before and again after
compilation on the Target (QNX)
B) Launch configuration:
The launch configuration detects only those files which it compiles, in our case as the files are compiled on the Target
(QNX) it gives error "Error exists in source , Do you still want to launch ?"
Can you guide some more steps, so that I can achieve my objectives of compiling on the target(QNX) and debugging from
the host (WIN)

Re: Remote compilation and debugging with QDE
Hi,
On your target system, you can create a CIFS share to publish your source projects on the network. Then, on your
Windows host, map a drive letter to that share and import the projects from it into your workspace using the "Existing
Projects into Workspace" import wizard. Make sure that the "Copy projects into workspace" option in the import wizard
is not selected, because you need to work with the files in-place in the shared directories.
With this set-up, I don't anticipate that there should be any unusual behaviour in launching and debugging processes. I
didn't understand your comment under item (B); launch configurations don't detect files and don't know anything about
compilation.
HTH,
Christian

Re: Remote compilation and debugging with QDE
How to create a CIFS share to publish your source projects on the network ?
I saw the fs-cifs
http://www.qnx.com/developers/docs/6.3.2/neutrino/utilities/f/fs-cifs.html
But that is only a client, and not the server.
Can you tell me how to start the server on QNX ?
Thanks
Akash

Re: Remote compilation and debugging with QDE
We tried copying the file manually , when we tried to launch we got the error that host library does not match the
target file.
Is there any good doucmentation or post that can help us solve the problem.
Thanks
Akash

Re: Remote compilation and debugging with QDE
The issue can be resolved by using the rsync, which synchronizes the host and the target file system.
A customized makefile, which copy the src from target to host , compiles on target and synchronizes the compiled source
back .
Will be able to do the entire steps.
QDE does not support RSE, which is plugin for eclipse, Hence we are not able to use the features automatically.
Are there any plans of supporting RSE on QDE?

Re: Remote compilation and debugging with QDE
What do you mean it does not support RSE? What version of eclipse this require?
