Link my Qt static library in to non Qt linux application

kumararajas

Hello,

I have build my Qt project as a static library and I have libabc.a

I want to link this library with other non Qt application. (Example "test")

I have used LIBPATH and set the path for my library.

And used LIBS and passed -labc to for the linkage.

But, when I build the application "test", While linking my Qt library, I get linker error:

/home/kumararajas/Blah/lib/libuicorelib.a(moc_telephonedelegate.o): In function `TelephoneDelegate::connectCall(bool)':
moc_telephonedelegate.cpp:(.text+0x60): undefined reference to `QMetaObject::activate(QObject*, QMetaObject const*, int, void**)'
/home/kumararajas/Blah/lib/libuicorelib.a(moc_telephonedelegate.o): In function `TelephoneDelegate::qt_metacall(QMetaObject::Call, int, void**)':
moc_telephonedelegate.cpp:(.text+0xb4): undefined reference to `QItemDelegate::qt_metacall(QMetaObject::Call, int, void**)'
/home/kumararajas/Integrate_UI/G-CPU/lib/libuicorelib.a(moc_telephonedelegate.o): In function `TelephoneDelegate::qt_metacast(char const*)':
moc_telephonedelegate.cpp:(.text+0x12c): undefined reference to `QItemDelegate::qt_metacast(char const*)'
/home/kumararajas/Blah/lib/libuicorelib.a(moc_telephonedelegate.o): In function `TelephoneDelegate::~TelephoneDelegate()':
moc_telephonedelegate.cpp:(.text._ZN17TelephoneDelegateD2Ev[_ZN17TelephoneDelegateD5Ev]+0x20): undefined reference to `QItemDelegate::~QItemDelegate()'

Is there anything more that I need to do link my Qt static library?

Thanks,
Kumara

Further to this post,

I continued with different tries.

Later,

I did try this:

 -lQtGuiE -lEGL -lIMGegl -lsrv_um -lQtNetworkE -lQtCoreE -lpthread

I linked the application "test" with my library and also with the above mentioned list.

This solves the problem.
Since the my Qt static library depends on other Qt libraries, i should link them as well..

But this time, I have a different error:

make[4]: *** [bin/FireApp] Error 1

This looks like standard library compatibility issue.

Any thoughts on this?
