I’ve been doing some funny stuff in personal projects with Qt. I’m not an expert in this so if it’s a dumb question (guess not I couldn’t find anything useful) feel free to kill me.
Anyway, I’m in OSX and usually I compile the final versions against a static version of Qt using a shell script with this commands:
cd "project folder...";
PATH=/Users/TCB13/(...)/qt-source/bin:$PATH; --> Path to my static QT.
export PATH;
qmake -config release;
make;
make clean;
So far if I move the compiled binary to another computer without Qt installed everything works just fine! 😉
Yesterday I start to play around with a dynamic library provided by a company and I’ve included the dylib in my .pro file like this: (I’ve a copy of the dylib in the project folder)
#macx: LIBS += -L$$PWD/ -lwpsapi
#INCLUDEPATH += $$PWD/
#DEPENDPATH += $$PWD/
And when I compile it “statically” (using the commands above) and run it on the other computer I get:
dyld: Library not loaded: @executable_path/libwpsapi.dylib
Referenced from: /Users/TCB13/Desktop/dude111
Reason: image not found
Trace/BPT trap: 5
I noticed that the size of my compiled binary is the same with or without including the dylib so, I googled how to include and external lib and some people are saying that I need to add “CONFIG += static” to my .pro file. I did it and the size of the file increased but I still got the same error.
Hope someone can help me.
The error message is pretty clear, you need to distribute libwpsapi.dylib with your application. If you want to avoid that, consult the documentation of this third-party library to make it use the statically linked code. Note that the fact that you are telling the linker to link a static library, does not mean that the code is referenced. I suspect that there is some kind of preprocessor #define in the code (or defaulted) to use the dynamically loaded library.
