Unable to link with PETSc

[shaharkadmiel]

Hi,

Trying to recompile this package on a new Mac running macOS Sierra.

./configure works fine but then make exits with the following error:

Unable to link with PETSc
ERROR: See "arch-darwin16.4.0-c-complex/conf/configure.log" file for details
make[1]: *** [.slepc-complex] Error 1
make: *** [extern] Error 2

Looking at the configure.log everything seems to be okay... well, I cant see any errors there.

Any Ideas?

I am having another go at this:

In the ncpaprop dir I did:

./configure --disable-library-guess \
  CXX=gcc CC=gcc FC=gfortran

gcc is version 7.3.0 (Homebrew GCC 7.3.0_1) and gcc, g++, and gfortran all point to the same version.

I got a positive output which ends in all Makefiles being created:

...
configure: creating ./config.status
config.status: creating Makefile
config.status: creating src/extern/Makefile
config.status: creating src/common/Makefile

config.status: creating src/tdpape/Makefile
config.status: creating src/wnlrt/Makefile
config.status: creating test/Makefile

I went on to make and made it as far as the .petsc-complex target. First I got:

===============================================================================
             Configuring PETSc to compile on your system
===============================================================================
TESTING: checkCxxCompiler from config.setCompilers(config/BuildSystem/config/set
*******************************************************************************
         UNABLE to CONFIGURE with GIVEN OPTIONS    (see configure.log for details):
-------------------------------------------------------------------------------
Cannot use C compiler gcc as the C++ compiler passed in with --with-cxx
*******************************************************************************

and compilation terminated.

I edited the src/extern/Makefile and removed the --with-cxx flag although it feels weird to have the --with-clanguage=cxx flag with only the --with-cc flag.

Now make made it to the .slepc-real target and died in the testing phase after this error:

...

 Number of requested eigenvalues: 4
make[4]: *** [makefile:186: testtest7f] Error 1
make[3]: *** [makefile:134: test_build] Error 2

At this point I don't know how to move forward...

Sorry for the delay. The configuration process has been completely rewritten and updated. Please see the new manual for details, but in short, you can try to run:

./configure --with-localpetsc

to have the build process download and install PETSc/SLEPc for you while it's setting things up.
