Summary	0002500: Can't build nglib on Mac OS X
Description	It might be a little unfair to report this as a bug to your project and not on nglib's project - but I did notice that ian.rees was the author of the Homebrew formula for nglib 5.3.1, (http://www.freecadweb.org/tracker/view.php?id=2432) and that ya'll apparently have an interest in keeping FreeCAD building on Macs. I'm just reporting that the brew formula hasn't been working for me. After a whole lot of chugging that includes 20 gigs of swap, I get a rare linker assertion error which is almost unknown to Google. The linker error is "ld: Assertion failed: (counter() < 0xffff)", which I think has to do with clang's hard limit of 2^16 linked classes. It's almost as if my build is hitting an infinite recursion of linking.
Steps To Reproduce	Installing nglib with Homebrew does it: Mon Apr 11 08:54:34:~$ brew install --with-oce nglib ==> Installing nglib from homebrew/science ==> Downloading https://downloads.sourceforge.net/project/netgen-mesher/netgen-mesher/5.3/netgen-5.3.1.tar.gz Already downloaded: /Library/Caches/Homebrew/nglib-5.3.1.tar.gz ==> Patching patching file libsrc/occ/Partition_Loop2d.cxx patching file ng/Makefile.in Hunk #1 succeeded at 327 with fuzz 1. ==> ./configure --prefix=/usr/local/Cellar/nglib/5.3.1 --disable-gui --enable-nglib --enable-occ --with-occ=/usr/local/opt/oce/inc ==> make install Last 15 lines from /Users/mkramer/Library/Logs/Homebrew/nglib/02.make: 0 0x10949697e __assert_rtn + 144 1 0x1094dec72 ld::tool::InputFiles::findDylib(char const, char const) + 1140 2 0x109478e14 generic::dylib::File<x86_64>::processIndirectLibraries(ld::dylib::File::DylibHandler, bool) + 82 3 0x1094df87b ld::tool::InputFiles::createIndirectDylibs() + 271 4 0x1094e07f0 ld::tool::InputFiles::forEachInitialAtom(ld::File::AtomHandler&, ld::Internal&) + 504 5 0x1094eadec ld::tool::Resolver::resolve() + 44 6 0x109497787 main + 940 7 0x7fff937205ad start + 1 A linker snapshot was created at: /tmp/libocc.0.dylib-2016-03-11-205543.ld-snapshot ld: Assertion failed: (counter() < 0xffff), function nextCounter, file /Library/Caches/com.apple.xbs/Sources/ld64/ld64-264.3.101/src/ld/ld.hpp, line 108. clang: error: linker command failed with exit code 1 (use -v to see invocation) make[2]: [libocc.la] Error 1 make[1]: * [install-recursive] Error 1 make: *** [install-recursive] Error 1 READ THIS: https://git.io/brew-troubleshooting If reporting this issue please do so at (not Homebrew/brew): https://github.com/Homebrew/homebrew-science/issues

ian.rees 2016-04-12 20:38 developer ~0006958	Thanks for the bug report, though I think we need to move this to the tracker at github: https://github.com/Homebrew/homebrew-science/issues Would you mind re-posting your bug there, and at-mention me ( @ianrrees )? This sounds like a weird issue, so might benefit from the increased traffic at homebrew-science compared to our issue tracker. Also would be good to know more info: * More about your OS and build environment (xcode version, etc). * Do you have opencascade or oce installed via Homebrew? * Have you tried installing nglib without oce? * Do you have any other package managers? Thanks! -Ian-

ian.rees 2016-05-04 09:42 developer ~0007042	Not a FreeCAD bug. Was an issue compiling nglib from git sources.
