GCC is not searching in /usr/local/lib. And after=20 recognizing that LIBRARY_PATH is not set at all in my environment (Gentoo=20 Linux), I installed quesa with --prefix=3D"/usr".=20 But linking my small app is still only possible when I provide the quesa=20 library explicitly: g++ /usr/lib/libquesa.so -o test-quesa test-quesa.o While I was compiling the quesa examples, I recognized that the examples al= so=20 provide the quesa library explicitly, so maybe this is not that wrong as i= =20 thought? e.g: gcc -DQUESA_HOST_IS_BIG_ENDIAN=3D0 -g -O2 -o dumpgroup dumpgroup-DumpGroup.= o=20 =2Drdynamic /usr/lib/libglut.so -L/usr/lib64 -lX11 -lXext -L/usr/local/lib= =20 =2DL/home/derber/bernhard/9.semester/programmierpraktikum/quesa/quesaexampl= es-1.6d20=20 =2Dlquesaqut /usr//lib/libquesa /usr/lib/opengl/nvidia/lib/libGL.so /usr/li= b/libGLU.so =2DL//usr/lib=20 =2DL/usr/X11R6/lib64 /usr/lib/libgtk.so /usr/lib/libgdk.so //usr/lib/libgmo= dule.so //usr/lib/libglib.so=20 =2DlXext -lX11 -lXext -lX11 -lX11 -lMesaGLU -lMesaGL -lX11 -lc -lX11=20 =2DL/usr/X11R6/lib -lX11 -L/usr/lib -lXext -lX11 -lX11 -lXext -lSM -lICE -l= Xmu=20 =2DlXt -lXext -lX11 -lpthread -lXext -lX11 -lXi -lXext -lX11 -lm -ldl=20 =2DWl,--rpath -Wl,/usr//lib -Wl,--rpath -Wl,//usr/lib-Wl,--rpath -Wl,/usr//= lib=20 =2DWl,--rpath -Wl,//usr/lib greetings to milano, Bernhard |
