[Octave-bug-tracker] [bug #50398] jit no longer compiles with Octave 4.2.1

[Rik]

Follow-up Comment #12, bug #50398 (project octave):

The functions DO seem to be in the library


root:~# nm -D /usr/lib/llvm-3.4/lib/libLLVM-3.4.so | c++filt | grep
verifyModule
0000000000b32d60 T LLVMVerifyModule
0000000000558e40 T llvm::verifyModule(llvm::Module const&,
llvm::VerifierFailureAction, std::__cxx11::basic_string<char,
std::char_traits<char>, std::allocator<char> >*)
root:~# nm -D /usr/lib/llvm-3.4/lib/libLLVM-3.4.so | c++filt | grep
verifyFunction
0000000000b32e00 T LLVMVerifyFunction
0000000000558af0 T llvm::verifyFunction(llvm::Function const&,
llvm::VerifierFailureAction)


I tried setting the environment variables as you suggested, but it still fails
to link.

I looked and "-lLLVM-3.4" is in the link command above.

Also, this is a NEEDED library.
