ifeffit: library path to gcc library is baked into configuration file, and is wrong

[paulfons]

The demeter build fails due to the gfortran library not being found. The relevant part of the log file is shown below. I am using Xcode 11.4. I can see that the gcc9 has been properly installed and the relevant libraries are located in "/opt/local/lib/gcc9/libgfortran.a", but it appears that clang doesn't look for the gfortran library in the right location. This would appear to be a bug. I am not sure how to modify the installation procedure to explicitly add an "-L/opt/local/lib/gcc9" to the build file for macports. Any help would be appreciated as I need the underlying package.

Any news of how to solve this?

try building it without the recently-added patchfile and see if that works. Sounds like <​https://github.com/bruceravel/demeter/issues/60> there is something odd going on there...

On 10.13, demeter installs as-is, without any trouble, without touching the existing Portfiles.

$ port -v installed demeter
The following ports are currently installed:
  demeter @0.9.26_0 (active) platform='darwin 17' archs='x86_64' date='2020-06-18T18:42:09-0700'

I just did that. Did not work. Attached is the main log

Main log

[reneeotten (Renee Otten)]

it doesn't build for me on 10.14 either. Looking at the logs, it appears the the compilation flags used are the ones from the ifeffit port. So if there is something wrong with those, the underlying issue could be in that port instead. I looked a bit yesterday, but am afraid I lack the knowledge for fixing this...

  6985 :info:build Ifeffit's installations directory is /opt/local/share/ifeffit
  6986 :info:build     (found by capturing `ifeffit -i`)
  6987 :info:build Compilation flags (from /opt/local/share/ifeffit/config/Config.mak):
  6988 :info:build      -L/opt/local/lib -lifeffit  -L/opt/local/lib -lpgplot -lpng -lX11  -L/opt/local/lib -L/opt/local/lib/gcc9/gcc/x86_64-apple-darwin19/9.2.0 -L/opt/local/lib/gcc9/gcc/x86_64-apple-darwin19/9.2.0/../../.. -lgfortran -lSystem -lgcc_ext.10.5 -lquadmath -lm

As Renee noted, the configuration flags from the ifeffit port appear to be wrong. Specifically, the location of the gcc libraries. This information is stored in this file:

/opt/local/share/ifeffit/config/Config.mak

I'm building this at present on 10.6.8, which uses gcc8, so I changed this:

LIB_F77  = -L/opt/local/lib -L/opt/local/lib/gcc8/gcc/x86_64-apple-darwin10/8.3.0 -L/opt/local/lib/gcc8/gcc/x86_64-apple-darwin10/8.3.0/../../.. -lgfortran -lSystem -lgcc_ext.10.5 -lquadmath -lm 

to this

LIB_F77  = -L/opt/local/lib -L/opt/local/lib/gcc8 -lgfortran -lSystem -lgcc_ext.10.5 -lquadmath -lm

and all is well:

$ port -v installed demeter
The following ports are currently installed:
  demeter @0.9.26_0 (active) platform='darwin 10' archs='x86_64' date='2020-06-19T10:23:40-0700'

clearly we need a better plan for:

/opt/local/share/ifeffit/config/Config.mak

[kencu (Ken)]

seem to run just fine on 10.6.8, by the way.
