coinor-liblemon: New port for the LEMON Library

[tre@…]

Hi,

I would like to add a new port named coinor-liblemon (analogously to the Coin-OR Debian packages) for the LEMON graph library, see ​http://lemon.cs.elte.hu

The library is a static C++ library using cmake and licensed under Boost. I successfully tested it under Lion and Mavericks.

Thanks in advance, David

Some observations:

• The empty depends_lib line should be removed because it does nothing.
• Since this software builds with cmake, consider using the cmake portgroup which should simplify the portfile.
• You've declared a dependency on python27 but don't appear to be using it.
• Forcing the compiler to gcc47 is going to be problematic on Mavericks and later for any other software that wants to use lemon; see wiki:FAQ#libcpp. Why can't lemon compile with clang?

Hi Ryan,

thanks for your hints. I cleaned it up accordingly. However, the gcc dependency seems to be mandatory for 2 reasons:

• the latest 1.3 release of LEMON won't compile with clang++ due to some flaws in the sources, e.g. I saw some missing typenames in template constructs etc.
• I created the LEMON port as the latest seqan-apps port depends on it. seqan-apps also depends on g++ as it relies on OpenMP for multithreading.

I'm optimistic that the LEMON developers will fix the clang++ compilation issues in the future. However seqan-apps won't lose its g++ dependency before Apple's clang++ supports OpenMP. :-(

Regards, David

I just replaced the "configure.compiler" entry by blacklisting clang which causes compiler problems (read above).

Hi there,

Can anyone of the MacPorts team please have a look at my final Portfile so that it can be eventually published?

Cheers, David

It builds fine on my local Mavericks - not sure why the build bot failed

  The C compiler "/opt/local/bin/llvm-gcc-4.2" is not able to compile a
  simple test program.

  It fails with the following output:

   Change Dir: /opt/local/var/macports/build/_opt_mports_dports_science_coinor-liblemon/coinor-liblemon/work/lemon-1.3/CMakeFiles/CMakeTmp

Hi,

that error seems to be unrelated to the coinor port. it seems that the C compiler is not available at /opt/local/bin/llvm-gcc-4.2 or broken. Cmake uses the CC environment variable to set the path for the C compiler. Can you check that the variable is set appropriately on the test system.

Cheers, Dave

What is the status here? Does "closed submission: fixed" mean that the port is available now?

[kurthindenburg (Kurt Hindenburg)]

Yes, it is in ports now since comment:11
