Hello, on my uclibc-hardened system, I experience this: | bombax ~ # gcc t.c -o t -lstdc++ -shared-libgcc | bombax ~ # ./t | ./t: can't resolve symbol '_Unwind_Resume_or_Rethrow' | bombax ~ # ldd ./t | libstdc++.so.6 => /usr/lib/gcc/i686-gentoo-linux-uclibc/3.4.4/libstdc++. so.6 (0x421db000) | libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x42285000) | libc.so.0 => /lib/libc.so.0 (0x4228c000) | libm.so.0 => /lib/libm.so.0 (0x422d9000) | ld-uClibc.so.0 => /lib/ld-uClibc.so.0 (0x421d0000) | bombax ~ # (see also bug #106670) Note that libgcc_s comes from /lib. | bombax ~ # equery belongs libgcc_s.so | [ Searching for file(s) libgcc_s.so in *... ] | sys-devel/gcc-3.4.4-r1 (/usr/lib/gcc/i686-gentoo-linux-uclibc/3.4.4/libgcc_s. so -> libgcc_s.so.1) | bombax ~ # /lib/libgcc_s.so does however not seem to belong to any package. Is this a left- over from the stage1 install? (which in the end can be called a bug?) Moving / lib/libgcc_s.so (and .so.1) out of the way makes /usr/lib/gcc/i686-gentoo-linux- uclibc/3.4.4/libgcc_s.so.1 being used and the above 't' programme work fine.

no, it isnt try copying /usr/lib/gcc/i686-gentoo-linux-uclibc/3.4.4/libgcc_s.so.1 to /lib/ and see if that fixes things
I moved libgcc_s.so and libgcc_s.so.1 to another directory, which should things exactly the same way as copying /usr/lib/gcc/i686-gentoo-linux-uclibc/3.4.4/ libgcc_s.so should do. (testing..) I just verified that it does. (So I still think this is a bug? not sure where though) Regards, Milan
it's a known issue of not being able to update the file with gcc-config automatically
*** Bug 109295 has been marked as a duplicate of this bug. ***
Have we fixed this with newer versions of gcc-config or eselect? If not, do we intend on doing so? :)
