LLVM installation in Windows

Project Infrastructure LLVM Dev List Archives

Hi everyone,

I am new in this field. I am trying to install LLVM in my 32-bit Windows XP. Can anyone please give a to do list for installing LLVM in my machine. When trying to build LLVM, I get the following error:

llvm[3]: Compiling llvm_ocaml.c for Debug build

Can anyone tell me what is the problem?

Possibly the OCaml bindings are broken on Windows/MinGW. Try building
with cmake instead of configure&make. The cmake build ignores the OCaml
bindings.

One does not need to use cmake build to disable buildings :slight_smile: It is
possible to configure with
--enable-bindings=none.

Also, I'd suggest to use at least LLVM release 2.8, not 2.7 one.

Thanks a lot both of you. Using --enable-bindings=none, I could build and install LLVM 2.8 and gcc-4.2-2.8 source. However, in the bin directory, I get c++.exe, cpp.exe, gcc.exe, g++.exe instead of llvm-c++.exe, llvm-cpp.exe, llvm-gcc.exe, llvm-g++. Are they the same?

Did you specify "--program-prefix=llvm-" on your configure line? That's what tells the llvm-gcc build to use the llvm-* names for the executables.

Thanks a lot. It worked !!!

Glad to hear that. Welcome to LLVM!
