Hello,
I have my own shared library and when I compile my C application with flag -lLEICAN (it is my library), there is not problem.
Now I have a QT application, and here there is a problem.
I have compiled QT application with the same flags, but g++ return me a error:
mydialog.cpp:(.text+0x3d1): undefined reference to........
Any advice???
Best regards.
You managed to cut the interesting part out of the error message. Could you paste the .pro file, linker command and the complete error?
OK!!!
app.pro
Output of compilerQuote:
TEMPLATE = app
INCLUDEPATH += .
# Input
HEADERS += global.h mydialog.h mydialog.ui.h taskman.h touchpad.h touchpad.ui.h
SOURCES += main.cpp mydialog.cpp taskman.c touchpad.cpp
In taskman.c there is other LEICANstop() function but in this case there is not problem.Quote:
