[LLVMdev] Compiling llvm and Clang on Linux (original) (raw)

Thanks for the information.

I am running on a machine on which gcc44 is installed but whose default installation is 4.1.2.

I ran ../llvm/configure CC=gcc44 CXX=g++44 make

and still got the same error (I checked and CC=gcc44 and CXX=g++44 now in build/Makefile.config).. I tried also

../llvm/configure CC=gcc44 CXX=g++44 --include_dir=

but it didn't help either.

I couldn't find in the gcc44 directories the the file gthr-default.h, on which the error is issued. The error is issued while compiling the line line #include in llvm/projects/compiler-rt/lib/asan/asan_posix.cc

the line is preceded by the comment // Should not add dependency on libstdc++

Below are the gcc44 directories installed on the machine. Do you know what else is needed in order to resolve the problem?

Thanks, Sitvanit

It's undocumented FAQ, if you are using RHEL5 (or clone).

Have fun!

ps. AFAIK, clang can be built more easily on centos6.

Hello all, I am new to this mailing list so I hope this is the right place to post the following question. We are considering using Clang front end for our tool. I tried to compile LLVM (using configure followed by make from the llvm top directory) on LINUX X86 with gcc 4.1.2. I got several compilation error messages of the form /usr/lib/gcc/i386-redhat-linux/4.1.2/../../../../include/c+ +/4.1.2/i386-redhat-linux/bits/gthr-default.h:117:1: error: weakref declaration must have internal linkage _gthrw(pthreadmutexattrdestroy) Could you guide me on how to resolve these errors? I downloaded the sources from the web page (not from SVN). Thanks, Sitvanit
