I'm trying to compile a software which links your PPL library, but at the linking step I got the error:

Undefined symbols for architecture x86_64 .... ld: symbol(s) not found for architecture x86_64

Here is my box configuration:

MacBook Pro OS X Yosemite 10.10.3 gcc/mp-4.7 MacPorts 2.3.3 PPL 1.1 (installed by MacPorts)

The installed libraries are located in /opt/local/lib:

libppl.13.dylib libppl.a libppl.dylib libppl_c.4.dylib libppl_c.a libppl_c.dylib

and the link options are

-L/opt/local/lib -lppl

I really cannot figure out why the library does not support the x86_64 architecture, because MacPorts had no problems at all in installing your library.

Dear Gaetano,

I was hoping someone more familiar than me with OS X could help you. Here is how I build the PPL on OS X:

export MACOSX_DEPLOYMENT_TARGET=10.10 export CC="gcc -stdlib=libc++ -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX${MACOSX_DEPLOYMENT_TARGET}.sdk" export CXX="g++ -stdlib=libc++ -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX${MACOSX_DEPLOYMENT_TARGET}.sdk" cd <gmp-build-dir> .../configure --prefix=$prefix --enable-fat --enable-cxx --enable-shared --disable-static make make install cd <ppl-build-dir> .../configure --prefix=$prefix --with-gmp=$prefix ...

Can you please try to reproduce something like this and see whether it works?

It would be really nice if you could help me, since the code is for a research project.

Please tell us more about this project. Kind regards,

Roberto
