The generated libtool for building libstdc++ adds the -nostdlib option to the g++ command for linking but doesn't add -lgcc. This causes a "hidden symbol" error when linking against the libstdc++ shared object. This patch adds gcc to the list of libraries linked against when linking libstdc++. /trunk/patches/gcc/4.2.1/300-libstdc++-nostdlib-linking.patch | 21 21 0 0 +++++++++++++++++ 1 file changed, 21 insertions(+)
