Which version of clang do you have installed? $ rpm -q clang clang-5.0.1-3.fc27.x86_64 *** This bug has been marked as a duplicate of bug 1544964 *** |
Description of problem: Running `$ CC=/usr/bin/afl-clang-fast ./configure` results to: configure: error: in `/home/nmavrogi/cvs/gnutls': configure: error: C compiler cannot create executables See `config.log' for more details Checking config.log shows: error: unable to load plugin '/usr/lib64/afl/afl-llvm-pass.so': '/usr/lib64/afl/afl-llvm-pass.so: undefined symbol: _ZTVN4llvm17GetElementPtrInstE' Thus is seems like there is an ABI change in one of the c++ libs this was compiled. How reproducible: ``` $ cat >c.c <<_EOF int main() { printf("hello\n"); } _EOF $ afl-clang-fast c.c afl-clang-fast 2.49b by <lszekeres> error: unable to load plugin '/usr/lib64/afl/afl-llvm-pass.so': '/usr/lib64/afl/afl-llvm-pass.so: undefined symbol: _ZTVN4llvm17GetElementPtrInstE' ```
