Hello Bob,

Thank you very much for your reply! But I am still messing around with qwt. After modifying the qwtconfig.pri, I recompiled the qwt project (from within Qt creator, or should I use the command line?). All went ok, and in the output directory are now the following files: libqwt.a and libqwt.prl. So I have compiled qwt as static library.

I opened the sinusplot example and added the library to the project:

Qt Code: 
  1. macx: LIBS += -L$$PWD/../../../build-qwt-Desktop_Qt_5_5_1_clang_64bit-Debug/lib/ -lqwt
  2.  
  3. DEPENDPATH += $$PWD/../../../build-qwt-Desktop_Qt_5_5_1_clang_64bit-Debug
  4.  
  5. macx: PRE_TARGETDEPS += $$PWD/../../../build-qwt-Desktop_Qt_5_5_1_clang_64bit-Debug/lib/libqwt.a
To copy to clipboard, switch view to plain text mode 

Tried to start it, but the program is still complaining "dyld: Library not loaded: libqwt.so.6.3", seems it is expecting a dynamic library.

Did I miss something? Some kind of settings in the .pro file?

Please have patience with me, I'm just beginning development with Qt under Max OS X

I would be grateful for a little bit further assistance,

Joerg
