Build errors on OSX Mavericks.

)(*&^%$ Apple! Grrrrrr.

I jut tried to use gplc and got a really odd message!

Seans-iMac:felt-prolog seancharles$ gplc --no-top-level command_line.prolog -o feltweb

ld: warning: ignoring file command_line.prolog, file was built for unsupported file format ( 0x25 0x25 0x3A 0x3A 0x3A 0x3A 0x3A 0x3A 0x3A 0x3A 0x3A 0x3A 0x3A 0x3A 0x3A 0x3A ) which is not the architecture being linked (x86_64): command_line.prolog

I vaguely remembered reading recently that Apple have done something funky with LLVM and gcc,

Seans-iMac:src seancharles$ gcc -v

Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk/usr/include/c++/4.2.1

Apple LLVM version 5.0 (clang-500.2.79) (based on LLVM 3.3svn)

Target: x86_64-apple-darwin13.0.0

Thread model: posix

Seans-iMac:src seancharles$ 

I went back in to my build folder and did a make clean and then a make, files compile OK but when it gets to the end of the process it all blows up in my face.

gplc -c --fast-math fd2c.pl

Fatal Error: Segmentation Violation (bad address: 0x0)

compilation failed

make[1]: *** [fd2c.o] Error 1

make: *** [all] Error 1

I remember reading something also about using “brew” to install an alternative version of GCC but is that going to break my Xcode installation or can I change it back?!

If anybody has any useful input on how to be able to build GNU Prolog again I’d appreciate it! I continue to dig...

Thanks,

Sean.
