Hello, on my uclibc-hardened system with gcc-3.4 I experience this: | bombax ~ # echo 'main(){}' > t.c | bombax ~ # gcc t.c -o t -lstdc++ | /usr/lib/gcc/i686-gentoo-linux-uclibc/3.4.4/libstdc++.so: undefined reference to `_Unwind_Resume@GCC_3.0' | /usr/lib/gcc/i686-gentoo-linux-uclibc/3.4.4/libstdc++.so: undefined reference to `_Unwind_RaiseException@GCC_3.0' | /usr/lib/gcc/i686-gentoo-linux-uclibc/3.4.4/libstdc++.so: undefined reference to `_Unwind_Resume_or_Rethrow@GCC_3.3' | collect2: ld returned 1 exit status | bombax ~ # gcc t.c -o t -lstdc++ -shared-libgcc | bombax ~ # The sablotron ebuild contains a line saying | append-ldflags -lstdc++ According to the above, it should read | append-ldflags -lstdc++ -shared-libgcc The gcc manpage states that -shared-libgcc is used automatically when using g++. (But sablotron can be linked from C programmes linked with gcc, so this is required.) Regards, Milan Reproducible: Always Steps to Reproduce: 1. 2. 3.
