problem bootstrapping the sys0.ji file

[spott]

I'm running into an issue with compiling julia:

https://gist.github.com/3107999

I'm compiling julia through homebrew, however it appears to be a julia problem that I'm having:

staticfloat/homebrew-julia#1

Let me know if I need to reproduce the problem somewhere else.

Mac people, assemble! cc @ViralBShah @StefanKarpinski

(Do we need a "mac" tag?)

[ViralBShah]

I think a mac tag is a good idea, and might as well add linux while we are at it. We already have windows.

Mac tag done (in brushed metal!)

Last time I had a problem like this, it was actually @JeffBezanson who knew what was going on, presumably due to his expertise in the whole sys0.ji business. :)

[nolta]

@spott, can you try building julia without using homebrew, and see if you run into the same problem.

[spott]

@nolta, I had done this before, and it worked, however, when I just did it, it failed. I'm not sure what changed in my environment since it worked before (well, a lot of things probably changed, it went from a brand new computer, to having a bunch of custom homebrew install stuff, but I don't know specifically what might have caused a problem.):

LINK usr/bin/julia-release-basic
LINK usr/bin/julia-release-readline
LINK usr/bin/julia-release-webserver

make: *** [release] Error 2 

I'm not sure how to get more verbose information out of the compilation, so I can't give you any more than that.

[samueljohn]

I can build julia fine with the same homebrew version as @spott.

[nolta]

I'm not sure what changed in my environment since it worked before:

Is this a fresh clone + build? If not, can you try git pull && make cleanall test?

And if that doesn't fix it, what's the output of:

$ cd base
$ gdb ../julia
...
(gdb) r -b stage0.jl
...
(gdb) bt

I gather you're trying this on a new retina macbook pro?

[spott]

This was a brand new git clone ### and make -j 7 (later replicated with just a regular make, though not completely rebuilt, should I do that?)

Let me know if you need anything else.

(these are short code snippets, if I should start putting them in gists instead of pasting them here, let me know.)

[nolta]

What's the output of git rev-parse HEAD?

And is this an ivy bridge mac?

Can you try the following:

$ make debug
$ cd base
$ gdb ../usr/bin/julia-debug-basic
...
(gdb) b jl_raise
(gdb) r -b stage0.jl
...
(gdb) bt

[samueljohn]

He has an ivy bridge mac. Retina MBP. Lucky one :-)

[spott]

Yes, I am running an IvyBridge retina MacBook Pro. :)

[nolta]

On your laptop:

CLT: 4.3.0.0.1.1249367152
GCC-4.0: N/A
GCC-4.2: N/A

but on my laptop:

CLT: 1.0.0.9000000000.1.1249367152
GCC-4.0: N/A
GCC-4.2: build 5666

What's the output of gcc --version and gcc-4.2 --version?

[spott]

And just to be sure, what's the output of file /usr/lib/libm.dylib?
