I still have the problem with the qprocess.
So now i set the output file to be in /opt/myapp
The installation add a text.txt in /opt/myapp/
In post installation i added:
chown -R user /opt/myapp/
chmod 777 /opt/myapp/*
But... when i'm running the process from code qprocess.start the output is always empty. I tried both ways start(path, argumenets) and start(" path and arguments in one string with spaces" )
When I'm running the process from command line on N900 the output text is filled.
on /opt/myapp/ls -la
i see the process as
rwxrwxrwx 1 user root
and the output file as
rwxrwxrwx 1 user root
------------
Thanks for help

Have you looked what kind of output does the process give when started?
Code:
QProcess p;
p.setStandardOutputFile("stdout.txt");
p.setStandardErrorFile("stderr.txt");
p.start("/opt/myapp/bigprocess", QStringList() << "/home/user/MyDoc/tmp/text.txt");

thanks for the suggestion with the ErrorFile!!! At least now i know why it is not working
I have an application installed in two locations:
/usr/bin/myapp
/opt/myapp/bigprocess
Inside myapp installed in usr/bin i start the bigprocess from opt.
QProcess p; p.start("/opt/myapp/bigprocess ", QStringList() << "/home/user/MyDoc/tmp/text.txt");when i run from command line the same command
/opt/myapp/bigprocess /home/user/MyDoc/tmp/text.txt my text is created and filled with data.
What do i do wrong?
Thanks
