Hi,
how do I compile LLVM for 64-bit on OS X? I want to get 64-bit libraries which
generate x86_64 to link them into a 64-bit application. All my attempts ended up
with either 32-bit libraries or errors. My machine is an Intel Xeon quad core,
'sysctl hw.cpu64bit_capable' returns 1 so I think the machine is fine.
- './configure && make' yields 32-bit libraries and executables
- I've tried various variations of ./configure --host X and ./configure
--target X. I am not sure which target triple to use (the getting started guide
says "The values of these options must be legal target triples that your
GCC compiler supports."). Unfortunately I couldn't figure out which
target triples to use. I've tried a few but until now I either get an error
when calling configure or I simply end up with 32-bit libraries. For instance
"i686_x86-apple-darwin9.0.0" results in "Invalid configuration
`i686_x86-apple-darwin9.0.0': machine `i686_x86-apple' not
recognized". "x86_64-apple-darwin9.0.0" configures and builds
fine but all libraries are 32-bit ("file libLTO.dylib" says
"libLTO.dylib: Mach-O dynamically linked shared library i386").
So, how can I build a 64-bit version for OS X? (Unfortunately prebuild
executables are not an option for me)
