can't build head on my os x 10.8 machine

[cartazio]

I recently installed rust head a few days ago, and today I did a clone into a directory so i could peruse rustc source. I just tried to build that clone today, at commit 1b12dca and the install fails.

heres the relevant build log

nb: i have xcode 5 installed, but the gcc in my path is gcc 4.8.

[alexcrichton]

I would recommend blowing away your local LLVM build tree and rebuilding LLVM. I've seen this often happen when LLVM gets out of date.

[cartazio]

I'll try that next. But i literally only did the clone < 1 hour ago! How could the llvm be out of date already?

[alexcrichton]

Hm, if this is a fresh build, then that's a little disturbing. This normally happens when old checkouts are updated with a new LLVM and things get out of sync. In your case, an LLVM rebuild may not be sufficient (sorry I should have read the initial report a little more closely).

[cartazio]

another important point is that i did make -j2, maybe I discovered a race condition in the build that borks something?

i'm going to try make clean ; wipe out llvm ; ./configure ; make with no -jN / -j flags and see if that works

[eminence]

i believe make clean-llvm is the canonical way to clean your local LLVM build tree

[cartazio]

ok, well, i'm going to just clone a fresh tree. Just tried building again and got

I've a theory that the issue is that i'm using gcc rather than clang. (specifically i'm using gcc 4.8)

I'll try using ./configure --enable-clang and report back.

and if that fails, I'll try to use the rust i've got installed locally as the boostrap one instead

[cartazio]

still getting this problem

[cartazio]

heres the output of my most recent configure run, where the associated build is currently in progress

build setup done as follow:

clone ; cd rust ; mkdir build ; ../configure ; make

nb, prior build attempts have been variations of clone ; cd rust ; ./configure ; make with experiments passing various flags to ./configure

[cartazio]

so brew install rust --HEAD works. this makes me suspect that somehow linking is using my llvm rather than rusts. Will report back on further experimentation

[cartazio]

failed again. same error as before.

now i'm testing brew install rust --HEAD, which had worked a few days ago. Ok, that worked.

will try some more ideas. This is weird

[cartazio]

current theory: cc points to xcode 5 clang, but gcc points to gcc 4.8.
doing more build testing to see having gcc and cc point to the same things works.

[cartazio]

solution:

cc,gcc,g++ need to respectively point to gcc,gcc,g++ or clang,clang,clang++, not some combination thereof.

this can be determined by

cc -version
gcc --version
g++ --version 

though this could also use the -v flag, which seems to give much more info
