Description
Since Qt 5.12.2 (and possibly 5.12.1, but I didn't try), when I cross compile qtbase
to an AM3359 platform, some libraries that link to OpenGL (e.g. libQt5Gui.so) have absolute paths as dependencies. The Qt platform on the target is eglfs.
There is a related bug report QTBUG-72903. I also posted the question already in the forum [0].
Here is the output from readelf -d libQt5Gui.so
0x00000001 (NEEDED) Shared library: [libQt5Core.so.5] 0x00000001 (NEEDED) Shared library: [libz.so.1] 0x00000001 (NEEDED) Shared library: [libpthread.so.0] 0x00000001 (NEEDED) Shared library: [/home/work/sdk/sysroot/usr/lib/libEGL.so] 0x00000001 (NEEDED) Shared library: [/home/work/sdk/sysroot/usr/lib/libIMGegl.so] 0x00000001 (NEEDED) Shared library: [/home/work/sdk/sysroot/usr/lib/libsrv_um.so] 0x00000001 (NEEDED) Shared library: [/home/work/sdk/sysroot/usr/lib/libGLESv2.so] 0x00000001 (NEEDED) Shared library: [/home/work/sdk/sysroot/usr/lib/libGLES_CM.so] 0x00000001 (NEEDED) Shared library: [/home/work/sdk/sysroot/usr/lib/libusc.so] 0x00000001 (NEEDED) Shared library: [libstdc++.so.6] 0x00000001 (NEEDED) Shared library: [libm.so.6] 0x00000001 (NEEDED) Shared library: [libgcc_s.so.1] 0x00000001 (NEEDED) Shared library: [libc.so.6] 0x0000000e (SONAME) Library soname: [libQt5Gui.so.5]
The relevant part in my mkspecs/qmake.conf file is as follows
QMAKE_LIBDIR_OPENGL_ES2 = $$[QT_SYSROOT]/usr/lib
QMAKE_LIBDIR_EGL = $$QMAKE_LIBDIR_OPENGL_ES2
QMAKE_INCDIR_EGL = $$[QT_SYSROOT]/usr/include
QMAKE_INCDIR_OPENGL_ES2 = $${QMAKE_INCDIR_EGL}
QMAKE_LIBS_OPENGL_ES2 = -lEGL -lIMGegl -lsrv_um -lGLESv2 -lGLES_CM -lusc
QMAKE_LIBS_EGL = $${QMAKE_LIBS_OPENGL_ES2}
