Extended Description

Steps:

1. From clean, build LLVM 2.6.
2. Run "make clean".

I get output like this:

make[1]: Entering directory /usr/local/google/home/nlewycky/2.6/llvm-2.6/bindings' make[2]: Entering directory /usr/local/google/home/nlewycky/2.6/llvm-2.6/bindings/ocaml'
make[3]: /usr/local/google/home/nlewycky/2.6/llvm-2.6/Release/bin/llvm-config: Command not found
make[3]: Entering directory `/usr/local/google/home/nlewycky/2.6/llvm-2.6/bindings/ocaml/llvm'
make[3]: /usr/local/google/home/nlewycky/2.6/llvm-2.6/Release/bin/llvm-config: Command not found
make[3]: /usr/local/google/home/nlewycky/2.6/llvm-2.6/Release/bin/llvm-config: Command not found
[...]

partway through the build. To help clarify the order of operations, I've attached the full transcript of the make clean run.

Hi,

I tried reproducing this bug on http://llvm.org/prereleases/2.6/ (Ubuntu 8.04.3 LTS) with the following configuration command:

../llvm-2.6/configure --prefix=pwd/../install --with-llvmgccdir=pwd/../llvm-gcc-4.2-2.6.x86_64-linux/ --enable-optimized --enable-targets=host-only --with-ocaml-libdir=pwd/../bindings

However, I don't encounter this bug. Can you post your exact LLVM configuration?

Thanks,

This looks like it occurs in the bindings/ocaml makefiles. You probably won't see it if you don't have ocaml installed. I think I can fix this pretty easily.

Fixed in svn r81547.

Thanks Bob! This has been merged into 2.6.
