Re: [eq-dev] Building on OSX 10.9 with XCode 5

[ben simons]

ok. cool. commented-out VRPN from configs/Equalizer.cmake

got a bit further. Lunchbox & GLStats built, then vmmlib died:

  CMake Error at CMakeLists.txt:41 (check_library_exists):
    Unknown CMake command "check_library_exists".

  -- Configuring incomplete, errors occurred!

Fixed this by adding:

include(CheckLibraryExists)

to Buildyard/src/vmmlib/CMakeLists.txt:23


then got:

Not sure why this has to be an Error and not just a Warning.
Line 50 Changed thus:

// main( int argc, const char* argv[] )
main( )


Maybe the [-Werror,-Wunused-parameter] flags aren't right for this platform?
...
That hack got a bit further. Then hacked more:

Added to: Buildyard/src/vmmlib/include/vmmlib/blas_daxpy.hpp:265

p = NULL;

but then kept getting loads of errors, so i hacked:
Buildyard/src/vmmlib/CMake/Compiler.cmake:33

    ## set(COMMON_GCC_FLAGS "${COMMON_GCC_FLAGS} -Werror")
    set(COMMON_GCC_FLAGS "${COMMON_GCC_FLAGS} -Wno-error")

and got past all the errors/warnings about unused parms && vmmlib built!

Collage built ok
Now seeing a pile of linking errors for: 

Linking CXX executable ../bin/eVolveConverter
ld: warning: ignoring file /usr/local/lib/libstdc++.dylib, file was built
for x86_64 which is not the architecture being linked (i386):
/usr/local/lib/libstdc++.dylib
Undefined symbols for architecture i386:
  "boost::program_options::to_internal(std::string const&)", referenced
from:
      std::vector<std::string, std::allocator&lt;std::string> >
boost::program_options::to_internal<std::string>(std::vector<std::string,
std::allocator&lt;std::string> > const&) in eVolveConverter.cpp.o
:
:

seems i386 is being selected - seems like there's a probably a simple config
variable
somewhere which is set to i386. That's where i'm up to. Thought i'd report
this progress...
