Building on OS X 10.9 fails at "python setup.py build_ext --inplace"

Building on OS X 10.9 fails at "python setup.py build_ext --inplace"

[paulinus]

thanks for reporting. I have no osx 10.9 close to debug. According to this, it seems related to clang using libstdc++.

Can you try compiling with the option -stdlib=libc++ ?

[chenosaurus]

hmm, a different error that doesn't really make sense ;( Running that command directly works tho. It only fails when running thru "python setup.py build_ext --inplace"

It seems the -std=c++11 is missing on the last command. Try using both -std=c++11 and -stdlib=libc++

I updated setup.py ln 107 to be:
extra_compile_args=['-std=c++11', '-stdlib=libc++'],

still getting same error.

$ python setup.py build_ext --inplace

Perhaps OS X is not the best env for working on this, I will try this in linux

[paulinus]

We do use OS X, should be no problem. It is weird that running the compilation line manually works, and not within setup.py. Can you try building with cmake?

[chenosaurus]

This fixed the issue:

extra_compile_args=['-std=c++11', '-stdlib=libc++', '-mmacosx-version-min=10.7'],

now hitting a missing library, should be easier to fix:

/usr/bin/clang++ -bundle -undefined dynamic_lookup -arch i386 -arch x86_64 -g build/temp.macosx-10.6-intel-2.7/opensfm/src/csfm.o -L/usr/local/lib -Lbuild/temp.macosx-10.6-intel-2.7 -lceres -lglog -lgflags -lboost_python -lvl -lmv -lakaze -o /Users/dchen/workspace/3rd-party/OpenSfM/opensfm/csfm.so
ld: library not found for -lvl
clang: error: linker command failed with exit code 1 (use -v to see invocation)

[chenosaurus]

Do you have any information on installing visualization library in os x?

[paulinus]

So vl is one of the static libraries generated by setup.py itself. Should be build when running

python setup.py build_clib

before

python setup.py build_ext --inplace

[chenosaurus]

Ah gotcha, got it built, thank you for the assistance!

[paulinus]

Cool, I've added the flags. Thanks for reporting!
