grass7 @7.0.2 Configure error - unable to locate LAPACK lib

[njeinstein]

When trying to install GRASS7, I run into the configuration error, "Unable to locate LAPACK library." I've tried manually uninstalling and reinstalling LAPACK (3.6.0_1), which itself installs without hitch.

I'm running El Capitan (v 10.11.4), and have Xcode version 7.3.1.

Please see attached log file and list of currently-installed ports.

Thanks!

I tried the following change:

Please note that you then need to activate atlas:

sudo port -v configure grass7 +atlas

But it fails with the following test which I didn't investigate further:

configure:10856: checking for dsegv_
configure:10882: /usr/bin/clang -o conftest -pipe -Os -arch x86_64  -I/opt/local/include  -L/opt/local/lib -L/opt/local/lib -Wl,-headerpad_max_install_names -framework OpenCL -arch x86_64  conftest.c  -lcblas -lf77blas -latlas   1>&5
Undefined symbols for architecture x86_64:
  "_dsegv_", referenced from:
      _main in conftest-wB0muu.o

Note that google "autocorrects" the search for dsegv into dgesv, so this could be a typo in configure.in in grass7.

Is this still a problem in the current version (7.8.3)?

[nilason (Nicklas Larsson)]

I think not. If I understand the reported issue correct it is based on +atlas variant which was replaced with +openblas:

​https://github.com/macports/macports-ports/commit/216ccac434fb61d04a79762b82d3059c96d75c63

Compiling with openblas went fine:

$ port installed
...
 grass7 @7.8.3_0+gui+openblas+postgresql10+python37+zstd (active)
...

OK, thank you. I'll close it then.
