The generated libtool for building libstdc++ adds the -nostdlib option to the |
| yann@1287 | 3 |
g++ command for linking but doesn't add -lgcc. This causes a "hidden symbol" |
| yann@1287 | 4 |
error when linking against the libstdc++ shared object. This patch adds gcc |
| yann@1287 | 5 |
to the list of libraries linked against when linking libstdc++. |
