...t; systemwide > ld? I tried setting the environment variables COMPILER_PATH=/usr/ > local/bin > and GCC_EXEC_PREFIX=llvm- but that had no effect. I see two solutions to this. One is to have llvm-gcc call llvm-ld when it has some option passed to it. Another would be to enhance 'collect2' to know about LLVM files. 'collect2' is a GCC utility invoked at link time, it would be the perfect place to add hooks. The thing we're missing most right now is a volunteer to tackle this project :) -Chris

...creation of "libz.a" works, but after that, zlib's Makefile wants to compile and link some example programs. The linking step fails: llvm-gcc --emit-llvm -DNO_vsnprintf -DUSE_MMAP -o example example.o \ -L. libz.a example.o: file not recognized: File format not recognized collect2: ld returned 1 exit status I can link it by hand using llvm-ld instead of llvm-gcc, like this: llvm-ld -o example example.o libz.a However, it is not possible to let the zlib Makefile issue that command without patching the Makefile, because the fragment that does the linking is hardcoded to...

...verything compiles fine (which is great), but I see that compiling/linking into bitcode files still hasn't been solved in a satisfying way. Until that gets resolved, I'm sending an updated script, that will do the trick. Usage: cd $LLVM_PATH/libexec/gcc/x86_64-unknown-linux-gnu/4.0.1/ mv collect2 llvm-collect2 copy the attached file to that directory The new collect will call llvm-collect2, unless you pass -enable-ld to it, in which case it will call llvm-ld, and link the bc files. To build an average app into bc files: 1) configure with standard llvm-gcc (don't pass -enable-ld to ll...

Hi all, I am having this error when i tried to compile a program /usr/bin/ld: cannot find -lncurses collect2: ld returned 1 exit status /usr/bin/ld: cannot find -lncurses collect2: ld returned 1 exit status Kindly help me out. Regard.

I hacked a replacement for llvm-collect2 (explained below), but such hackery is really not a way to go in the long term. I'm very hopeful that Chandler's work will solve the problem for good. Hack explained: 1) rename llvm/libexec/gcc/x86_64-unknown-linux-gnu/4.0.1/collect2 to collect2-llvm 2) put the attached script collect2 in...

1) Build clang with GCC-4.9.2, when compling other application s with clang/clang++, the default linker is ld, can I replace it with other linker tool， if we can, how to do it? I.E. can we use collect2 instead? 2) how to specify the path, if we do not use the default vertion GCC? Best Regards!
