Compilation of lanczos module fails under Mac OS X 10.10.5 and Xcode 7.0 #24

Closed auerl closed 7 years ago

auerl commented 9 years ago

We tried installing obspyDMT on a Mac (10.10.5) with Xcode 7 using the following steps:

  1. Download anaconda 2.3.0 for mac from http://continuum.io/downloads#all
  2. Install anaconda
  3. source ~/.bash_profile
  4. conda install -c obspy obspy
  5. conda install basemap
  6. git clone https://github.com/kasra-hosseini/obspyDMT.git
  7. pip install ./obspyDMT

When trying to install with pip we get the following compilation error:

gcc -bundle -undefined dynamic_lookup -L//anaconda/lib -arch x86_64 -arch x86_64 build/temp.macosx-10.5-x86_64-2.7/obspyDMT/src/lanczos.o -L/usr/local/lib/gcc/x86_64-apple-darwin14.4.0/5.1.0/../../.. -L//anaconda/lib -lgfortran -o build/lib.macosx-10.5-x86_64-2.7/obspyDMT/lib/obspyDMT.so
ld: library not found for -lgcc_s.10.5
collect2: error: ld returned 1 exit status
error: command 'gcc' failed with exit status 1

Apparently the gcc_s.10.5 library has been renamend with in the latest xcode update.

cd /usr/local/lib sudo ln -s ../../lib/libSystem.B.dylib libgcc_s.10.5.dylib sudo ln -s ../../lib/libSystem.B.dylib libgcc_s.10.4.dylib

and rerunning pip install ./obspyDMT seems to be an acceptable workaround.

Maybe this issue could be resolved with a fix in setup.py?

Cheers,

L.

Thanks for reporting this issue! As you have already mentioned, this occurs in installation of lanczos module (an external FORTRAN code in obspyDMT that should be compiled first). I changed the code accordingly. Can I ask you to update your obspyDMT to the latest version and re-try the steps that you mentioned? I hope the issue is already resolved. If not, I would appreciate that if you send me the error message.

Cheers, K
