Error compiling Regex at startup

[thrasibule]

This is on gentoo 32bits. This is the error I get when trying to start julia after install:

error compiling Regex: error compiling compile: error compiling info: could not load module libpcre: /usr/bin/../lib/libpcre.so: invalid ELF header
in isrooted at file.jl:80
in abs_path_split at file.jl:109
in abs_path at file.jl:141
in julia_pkgdir at client.jl:215
in _start at client.jl:246

This is related to issues #949 and #450 I think because on gentoo /usr/lib/libpecre.so is a script that contains the following:

/* GNU ld script
Since Gentoo has critical dynamic libraries in /lib, and the static versions
in /usr/lib, we need to have a "fake" dynamic lib in /usr/lib, otherwise we
run into linking problems. This "fake" dynamic lib is a linker script that
redirects the linker to the real lib. And yes, this works in the cross-
compiling scenario as the sysroot-ed linker will prepend the real path.

See bug http://bugs.gentoo.org/4411 for more info.

OUTPUT_FORMAT ( elf32-i386 )
GROUP ( /lib/libpcre.so.1 )

I'm doing USE_DEBIAN=1, so this is not using the bundled pcre with julia. What's strange is that julia compiles and start fine from the source directory. I can also run the test suite successfully from there. But after doing a make install, julia fails to launch. Any ideas what's going on?

Thanks,
Guillaume

I'm investigating this right now, its related to #1690, once that is solved, this may be solved as well

In the meantime, you can try compiling without USE_DEBIAN=1. The debian special case simply automatically uses a bunch of dependencies, and then tells Julia to store libraries in a multiarch structure, as debian likes. It's this second part that #1690 is trying to solve.

In the meantime, you can likely compile just by using the appropriate USE_SYSTEM_<LIBNAME>= make vars without trying to use a multiarch library structure if you want to:

$ export BUILDOPTS=""
$ for lib in LLVM ZLIB SUITESPARSE ARPACK BLAS FFTW LAPACK LIGHTTPD GMP PCRE LIBUNWIND READLINE GLPK; do \
> export BUILDOPTS="$BUILDOPTS USE_SYSTEM_$lib=1"; done
$ make $BUILDOPTS install

Hopefully we'll soon have multiarch installation ironed out.

Possibly related, on 0dba9af and Mac OS 10.8.2, I'm also getting a libpcre related error on boot of julia:

exec: error -5
 in exec at pcre.jl:108
 in search at regex.jl:113
 in split at string.jl:953
 in abs_path_split at file.jl:110

[staticfloat]

Did you compile the debug version of Julia?

[blakejohnson]

No, just make clean followed by make. Also tried make cleanall... same result.

[staticfloat]

Please open a new issue, I think this is something new. :)

[blakejohnson]

Okay, opened #1732

[JeffBezanson]

Is this still a problem?

[blakejohnson]

It isn't a problem on Mac OS.

Problem is gone on gentoo as well.
