"make" on OSX fails

[rstout]

OSX 10.9.1

Commands I ran leading up to the issue:

$> git clone https://github.com/mozilla/rust.git 
$> cd rust
$> ./configure
$> make install

"make install" outputs the following error message:

make[2]: *** No rule to make target `/home/rust/src/llvm/home/rust/x86_64-apple-darwin/llvm/Makefile', needed by `Makefile'.  Stop.
make[1]: *** [clean-llvmx86_64-apple-darwin] Error 2
make: *** [/home/rust/x86_64-apple-darwin/llvm/llvm-auto-clean-stamp] Error 2

The issue is that the path "home/rust/x86_64-apple-darwin/llvm/Makefile" has been appended to the path "/home/rust/src/llvm", and I imagine that the path should just be "home/rust/x86_64-apple-darwin/llvm/Makefile". Looking at the output of "make --print-data-base", I found:

# makefile (from `Makefile.config', line 55)
PROJ_SRC_DIR := /home/rust/src/llvm/home/rust/x86_64-apple-darwin/llvm

There are other variables that are assigned the same broken path that PROJ_SRC_DIR is, but after my preliminary debugging I think PROJ_SRC_DIR might be the culprit. On line 55 of rust/x86_64-apple-darwin/llvm/Makefile.config:

PROJ_SRC_DIR := $(LLVM_SRC_ROOT)$(patsubst $(PROJ_OBJ_ROOT)%,%,$(PROJ_OBJ_DIR))

I've only ever written the most trivial of Makefiles, so I don't really know how to continue here.

Do you have the full log of a session? I just tried to reproduce this but was unable to.

[rstout]

Here's the output of "make":

https://github.com/rstout/misc/blob/master/make_output.txt

and the output of "make --print-data-base":

https://raw2.github.com/rstout/misc/master/make_print_data_base.txt

[alexcrichton]

Do you have some symlinks in your path? It looks like it's using realpath in a few places and llvm's makefiles might be getting confused.

[rstout]

The issue still occurs after getting rid of all the "alias" declarations in my .bash_profile

[alexcrichton]

Oh sorry, by path I mean the path to the rust source code.

[rstout]

No, there aren't any symlinks in my path (I used ls -l to determine this)

[rstout]

This issue has gone away when building from master today (2/4/14)

[mindon]

got same issue ... today

[richo]

It seems very unlikely this is the same root cause, so can you open a new issue with the full build log?

[mindon]

llvm[2]: Constructing LLVMBuild project information.
make[2]: * No rule to make target '/Users/lab/rust/src/llvm**/Users/lab/rust/x86_64-apple-darwin/llvm/Makefile', needed by 'Makefile'. Stop.

the Makefile path is repeating something...

[richo]

I still somewhat doubt that this is the same issue.

Could you post a full build log in a new issue?
