Try this patch:

http://lists.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20070507/049497.html

I'm pretty certain the patch resolves any issue with the dejagnu variables.
Re-open if the problem persists.

I'm stilling getting this with a Release build on x86 (after using the new
Makefile):

Shouldn't it be look in Release/lib?

Yes. The question is, why isn't it. The Makefile.rules has (paraphrased):

ifdef ENABLE_PROFILING
BuildMode := Profile
else
ifeq ($(ENABLE_OPTIMIZED),1)
BuildMode := Release
else
BuildMode := Debug
LD.Flags := -g
endif
endif

LibDir := $(PROJ_OBJ_ROOT)/$(BuildMode)/lib
LLVMLibDir := $(LLVM_OBJ_ROOT)/$(BuildMode)/lib

LD.Flags += -L$(LibDir) -L$(LLVMLibDir)

So, for it to come out with the result you had, ENABLE_OPTIMIZED had to be not 1

Are you sure you're building with ENABLE_OPTIMIZED=1 ?
Reid.

Yes I am:

Trez weird.

I'll poke around some.

This isn't a 2.0 blocker so no hurry. Worst case, I can remove the test from the
release.

Tanya,

I can't reproduce this. I get:

Do you have environment variables overriding any of the Makefile variables?

No. I don't have anything but PATH and CVSDIR set.

Do you have a release build? Its probably better if you can reproduce this in
your tree or not. If you don't have time, no big deal. Like I said, its not a
release blocker. Thanks Reid.

Its not a release blocker, but its a concern because if it can happen here, it
can happen on any build and that's a major issue for 2.0.

I do have a release build and it works fine .. but perhaps only because its
finding my debug build too, in the same directory. I'll try it in a separate
environment and see what happens.

Yeah, try it after you delete your Debug dir.

Even with the Debug directory gone, it still works fine using Release binaries:

I verified manually that the program generated by llvm2cpp could be compiled,
executed and that it produced the same .ll file as the input.

I don't know what's going on in the 2.0 release, but this is definitely working
for 2.1
