Maybe I wasn't
clear. The "g++" is ordinary vanilla g++, not llvm-g++. Are there
any versioning issues with regular g++ compiling llvm2cpp generated
This could be the weak link. llvm2cpp is a relatively new and fairly
untested addition to the llvm toolsuite. Its purposes are more for
instruction and example generation than for use in compiling. It is
entirely possible that llvm2cpp is not generating *exactly* the
C++ code necessary to recreate your module. This is especially true
since your source language is Objective-C and that has never been tried
Hmmm. When I was trying to compile this stuff, I remember that at one
point I got an error relating to a function return ...Basictype rather
than ...Kindtype. The prototype and the real implementation of the
function had different return types. I changed the real implementation
to match the prototype and everything compiled. I wonder if this is
somehow affecting the code that llvm2cpp is creating.
llvm2cpp came from the llvm tarball. My g++ was 4.1.1. The LLVM
libs are from the llvm tarball I believe and the objc library is
probably the gcc 4.1.1 one. What other information would help?
Well, what are you trying to accomplish?
I am tinkering with a language, call it "foo", that is similar to
C++ and we were looking at the possibility of creating a llvm2foo.
We want to support objective-c so we were looking at a path:
obj-c => ... => foo.
>>> cfrontend-g++ -o bar.bc bar.m
>>> llvm2cpp -o bar.cpp bar.bc
>>> g++ -c bar.o bar.cpp
>>> ld -o bar bar.o -l objc -l LLVMCore -l LLVMSupport -l LLVMSystem
Are you just trying to get your bar.m program to run? If so, there's a
route that doesn't involve llvm2cpp:
I've gotten bar.m to run the "normal" way, i.e., "g++ bar.m".
