The basic problem is glxinfo (C program) links against libGLU.so (C++ built library). But glxinfo fails to link using gcc: ... gcc -o glxinfo -g -O -ansi -pedantic -Wall -Wpointer-arith -Wstrict-prototypes -Wmissing-prototypes -Wmissing-declarations -Wredundant-decls -Wnested-externs -Wundef -L../../exports/lib glxinfo.o -lGLU -lGL -lXext -lX11 -lpthread -lm -Wl,-rpath-link,../../exports/lib ../../exports/lib/libGLU.so: undefined reference to `_Unwind_SjLj_Resume@GCC_3.0' ../../exports/lib/libGLU.so: undefined reference to `_Unwind_SjLj_Register@GCC_3.0' /usr/bin/../lib/libstdc++.so.5: undefined reference to `_Unwind_SjLj_RaiseException@GCC_3.0' ../../exports/lib/libGLU.so: undefined reference to `_Unwind_SjLj_Unregister@GCC_3.0' /usr/bin/../lib/libstdc++.so.5: undefined reference to `_Unwind_SjLj_Resume_or_Rethrow@GCC_3.3' collect2: ld returned 1 exit status ... If I use g++ instead, glxinfo links just fine since libgcc_eh.a gets picked up automagically. But it seems wrong to require a C program link using g++. Is libGLU.so getting built wrong? (ie resolved in libGLU.so directly) Or should C programs not use C++ built libs? (How can the author know?) Or is this a bug in gcc/binutils? (not picking up libgcc_eh.a) This might be a generic problem since a few other libs on my box have _Unwind_SjLj_Resume (for example) unresolved: libasprintf.a libgmpxx.a libncurses++.a thanks, grant
