Hi, I was trying how to call OCaml code from a LLVM pass. First, I tested how to call OCaml from simple C++ code, which works. But when I was calling OCaml from LLVM, I have the following problems: 1) A linkage error. To call OCaml from C++, we need to link to libcamlrun.a, which defines the interfaces between C and OCaml. But libcamlrun.a also has a main function. So ld complains it conflicts with the main function in opt.cpp. I did not have this error in simple C++ and OCaml code. I might screw something up. It reports errors when compiled both as shared librarie...
