I get roughly the following for both 32-bit and 64-bit builds on lion. Has anyone specifically diagnosed the issue building current releases up to, and including the current dev branch, on mac os x? Is this considered an gcc-llvm or otp issue?
$ ./configure --enable-darwin-64bit --disable-hipe
$ make

LLVM on Lion appears to generate bad code when used with default
optimizations. Use:
CFLAGS=-O0 ./configure ....
Be sure to start from a fresh unpack of OTP source too...

| You can also download the 64 bit Mac OS X Lion package from Erlang Solutions website: |

Just a follow-up on this. Installing gcc 4.5.3 from macports, allows the current dev branch to build and pass most of the tests.

I do not have a Mac and for this reason perhaps I should not really
care, but if I had one I would have found this information a bit
uninformative.
The interesting question is whether the dev branch passes at least all
tests as those when compiled with -O0, i.e. whether the optimization
passes in the updated macports compiler are still causing trouble for
(parts of) Erlang/OTP or not.
If not, either the compiler or Erlang/OTP needs fixing. Till then I
would recommend to all MacOS users to keep using -O0 anyway.

FWIW: I am running on Mac OS X and installed Erlang with Homebrew and
have had no issues: http://mxcl.github.com/homebrew/

Yeah, sorry about that. The tests take a long time to run and I wanted to let other mac users know that there was a possible viable alternative.
I'm running more tests off and on today and will report those results, if there is interest.
Was kinda hoping to move mac users past the "use -O0" impasse...

We hope to have R14B04 to build out-of-the-box
on Lion. Our plan is to have 'configure' set up
the Makefiles so that beam_emu.c is built with
gcc-4.2 and everything else with the default
compiler (usually llvm-gcc-4.2.).
Until then, the easiest way to build Erlang/OTP
seems to be:
CC=gcc-4.2 ./configure
make
We have not run all test suites on Lion yet,
but I have successfully built Erlang/OTP and
run the emulator and compiler test suites.
Our long-term plan is to find out exactly what
causes the problem compiling beam_emu.c
and submit a bug report to the llvm team.

Hi,
Is there a target date for R14B04? I look around on the erlang.org site
and can't seem to find it.
Thanks
