Hello and happy new year, everyone!
Four years after my successful installation of the Faust opcodes on Ubuntu with LLVM 3.3 (https://github.com/csound/csound/blob/develop/BUILD.md#faust-opcodes), I'm stuck once again with the same problem with LLVM 5.0 on Ubuntu 18.04.
I have FAUST Version 2.14.2 Build with LLVM version 5.0.1 with libfaust.a at /usr/local/lib/.
My cmake command:
cmake -DLLVM_DIR=/usr/lib/llvm-5.0/share/llvm/cmake -DCMAKE_MODULE_LINKER_FLAGS="-L/usr/lib/llvm-5.0/lib" -DBUILD_FAUST_OPCODES=1 -DFAUST_LIBRARY=/usr/local/lib/libfaust.a ..
produces:
-- BUILD_FAUST_OPCODES is enabled.
but csound -z (Csound version 6.13 beta (double samples)) doesn't show the Faust opcodes and seems to be missing some links:
WARNING: could not open library '/usr/local/lib/csound/plugins64-6.0/libfaustcsound.so' (/usr/local/lib/csound/plugins64-6.0/libfaustcsound.so: undefined symbol: _ZTIN4llvm7CmpInstE)
What linking steps am I missing?
Thanks

Looks like an LLVM symbol not defined in the faust opcode lib build. Make sure you don't have more than one llvm versions in
your system.
The symbol's mangled name is
LLVM 5
I think there is a lib version mismatch somewhere.
