32bit OpenBLAS build with 64bit Julia by default on OSX 10.6.8

[cmcbride]

On recent master branch:

[nibbler julia]% cat .git/refs/heads/master c575520aa51331b771af8c3a077cc06013a8505f

Julia builds in 64-bit, but OpenBLAS appears to build in 32-bit:

[nibbler julia]% ./julia ERROR: OpenBLAS was not built with 64bit integer support. You're seeing this error because Julia was built with USE_BLAS64=1 Please rebuild Julia with USE_BLAS64=0 Quitting.

@ViralBShah Thinks this might be due to gcc.

What OSX version, @staticfloat https://github.com/staticfloat ?

0d39c663f84bcf38157548d1b8d4cb833a263f02 still works for my setup (10.6.8 with the MacPorts PCRE installed on system that Julia avoids).

regex.jl:7-21

immutable Regex
    pattern::ByteString
    options::Uint32
    regex::Array{Uint8} <== The problem is with this cached data
end

The problem isn't which version of PCRE we have, the problem is we need to use exactly the same version when compiling the sys.ji file as we use when running julia. I suspect @stevengj results were simply a red herring. (especially since we recently switched from typically using Homebrew and ignoring Macports at sys.ji build time, to using julia's at all times)

3873 could perhaps be of use, to test the value of Base.PCRE.VERSION against the result of calling pcre at boot

@vtjnash Did you ever figure out what about PCRE causes these problems? I was not able to determine, but I could take another look.

[vtjnash]

the problem is that we sometimes link against /usr/local/lib and sometimes don't. if the version of PCRE changes between linking (building sys.ji) and runtime, the compiled regexes are invalid.

[staticfloat]

So the problem was never that we were configuring pcre incorrectly? Just that build-time and runtime pcre were not the same?

[vtjnash]

right

Sorry to respond to an old and closed topic, but this problem exists also on openSUSE 13.1. I have an openblas library in my LD_LIBRARY_PATH which was compiled without the support of 64 bit integers. This problem is solved as suggested before by running:

LD_LIBRARY_PATH='' ./julia

Another solution is to recompile the system version of openblas using the following flag:

make INTERFACE64=1
