QProcess / system call not working under linux. Why?

[johnny_sparx]

Hello, thanks to all that replied to my previous posts.

I wish to execute the following command (which works fine at the actual command line - tested under linux already):

dcmodify -m "(0010,0020)=123456789" /export/data/jsalik/DICOM_DB/PENDING/SEBASTIAN_HEAD_4/*.*

I tried the following code:

QString Command_Line = QString("dcmodify -m")+QString("\"(")+Key_String_Value+QString(")=")+Data_Value+"\" ";
    #ifdef Q_WS_WIN
    Command_Line+=QString("\"")+Target_File_Path+QString("\\")+File_Name+QString("\"");
    #else
    Command_Line+=(Target_File_Path+"/"+File_Name);
    #endif
 
    System_Call.start(Command_Line);
    System_Call.waitForFinished();

QString Command_Line = QString("dcmodify -m")+QString("\"(")+Key_String_Value+QString(")=")+Data_Value+"\" ";
    #ifdef Q_WS_WIN
    Command_Line+=QString("\"")+Target_File_Path+QString("\\")+File_Name+QString("\"");
    #else
    Command_Line+=(Target_File_Path+"/"+File_Name);
    #endif

    System_Call.start(Command_Line);
    System_Call.waitForFinished();

It seems to work just fine under windows.

nothing seems to happen. I do not even get anything when I try to dump the standard output. Can anyone tell me why?
