[solved] PRO function calls

urgentDiplomacy

Hello,

I am developing on 64bit Win7 and am trying to figure out why a
@system(cd $$mydir)@

call in my .pro file is not working. I have tried hard coding the path
@system(cd C:/)@

changing the cd call to chdir and even trying different combinations of parenthesis and still have issues. Here is my stub:
@

QT += core

QT -= gui

TARGET = test
CONFIG += console
CONFIG -= app_bundle

TEMPLATE = app

SOURCES += main.cpp

system(cd C:/)
system(dir)
@

This setup seems to work fine on Linux (with the appropriate changes to mydir and dir call). Is this a known compatibility issue? I have not found any documented forms of it...

I do not think changing directories is a good idea in qmake. What do you want to do?

I have some code generation scripts that need to run on compilation in another directory, normally I would readjust the way the script executes but this is a part of a much larger project and editing the script may destabilize other coder's projects. I cannot really make this a 'one-off' solution unfortunately.

I don't know why you think this works on Linux. IMO, this should fail under any OS. As the command passed to system() will run in another process.

If you're not able to change the original scripts, I would write wrapper script that takes the desired directory as argument, changes directory to it and calls then calls the original script.

Thanks Volker and Herder for your help! I should have said that some people on my project believe that it works in linux but it doesn't for the reasons you specified Herder.

[SOLVED] thanks to Herder.
