QProcess on linux - problem with shared libraries

[michallen]

Hi. I`ve written this code :

QProcess *myProcess = new QProcess();
 
    QProcessEnvironment env = QProcessEnvironment::systemEnvironment();
 
    env.insert("LD_LIBRARY_PATH", "/home/khoros2200/lib");
 
    myProcess->setProcessEnvironment(env);
 
    myProcess->execute("/home/khoros2200/bin/karith1")

QProcess *myProcess = new QProcess();

    QProcessEnvironment env = QProcessEnvironment::systemEnvironment();

    env.insert("LD_LIBRARY_PATH", "/home/khoros2200/lib");

    myProcess->setProcessEnvironment(env);

    myProcess->execute("/home/khoros2200/bin/karith1")

To copy to clipboard, switch view to plain text mode 

;

and i have this error :

/home/khoros2200/bin/karith1: error while loading shared libraries: libkdmanip.so: cannot open shared object file: No such file or directory

when I execute the program in console , it works properly . When I unset the LD_LIBRARY_PATH variable I get the same mistake as in Qt Creator. So what`s the problem ? Why is QProcess doesn`t see envioronment variables ?
