[SOLVED]Linking Internal library with VERSION tag

ExorcistInc

Hi!

I have dynamic library in my project. Let it be "SignalProcess". I added it to project with Qt Creator "Add library..." dialog
Here what i got:

win32:CONFIG(release, debug|release): LIBS += -L$$OUT_PWD/../SignalProcess/release/ -lSignalProcess
else:win32:CONFIG(debug, debug|release): LIBS += -L$$OUT_PWD/../SignalProcess/debug/ -lSignalProcess
else:unix: LIBS += -L$$OUT_PWD/../SignalProcess/ -lSignalProcess

INCLUDEPATH += $$PWD/../SignalProcess
DEPENDPATH += $$PWD/../SignalProcess

It works fine until adding VERSION = 0.5.0 to SignalProcess. After it, build ends with error:

cannot find -lSignalProcess

I am using Qt 5.4.1 with MinGW 4.9.1 32bit under Windows 8.1 x64

How is it possible to fix this?

So, I found one solution:

win32:CONFIG(release, debug|release): LIBS += -L$OUT_PWD/../SignalProcess/release/ -lSignalProcess$$VER_MAJ
else:win32:CONFIG(debug, debug|release): LIBS += -L$OUT_PWD/../SignalProcess/debug/ -lSignalProcess$$VER_MAJ
else:unix: LIBS += -L$OUT_PWD/../SignalProcess/ -lSignalProcess

Unfortunately, for some reason, VER_MAJ is not setted, even if VERSION is setted.
But, after adding VER_MAJ = 0 to .pro file, the application begins to compile.

Could it be something better than this? And why VER_MAJ is not setted by qmake?

Hi,

according to the doc VER_MAJ is set only for lib projects

Thanks for reply!

Than, if I have project with subdirs, where one is lib with

TARGET = SignalProcess
TEMPLATE = lib
VERSION = 0.5.0

And other is application, why

win32:CONFIG(release, debug|release): LIBS += -L$$OUT_PWD/../SignalProcess/release/ -lSignalProcess
else:win32:CONFIG(debug, debug|release): LIBS += -L$$OUT_PWD/../SignalProcess/debug/ -lSignalProcess
else:unix: LIBS += -L$$OUT_PWD/../SignalProcess/ -lSignalProcess

INCLUDEPATH += $$PWD/../SignalProcess
DEPENDPATH += $$PWD/../SignalProcess

does not work? (ends with "cannot find -lSignalProcess" error)

HI,

in Windows the major_version became part of the library name, so you need to specify it when you want link the library

Ok, thank you!
just a little bit confused, that qmake could not generate right makefile without support:)
