QMYSQL driver not loaded, tried all hints

Does anyone knows why the libs aren't found in the first place? I checked the Makefile produced by qmake and it seems fine....
C std library don't appear to be linked in object file

Using nm(1) to list symbols from object file built for arm64 on OS X
The system nm doesn't read arm64. You need to use the nm that came with your arm64 SDK (i.e. the iphoneos SDK in Xcode). This is the same path as where you ran clang. $ xcrun -sdk iphoneos clang -arch arm64 main.c $ xcrun -sdk iphoneos nm a.out 0000000100000000 T...
