PETSc download (prior to PFLOTRAN) Error Msg: UNABLE to CONFIGURE with GIVEN OPTIONS (see configure.log for details): -----Cannot request fblaslapack without Fortran compiler

[Richard -Chip- Fisher]

Hi, 

When I was downloading PETSc prior to installing PFLOTRAN, I got an error message regarding the fblasklapack package.

My commands were:

git clone https://bitbucket.org/petsc/petsc petsc

cd petsc

git checkout xsdk-0.2.0

./configure --CFLAGS='-O3' --CXXFLAGS='-O3' --FFLAGS='-O3' --with-debugging=no --download-mpich=yes --download-hdf5=yes --download-fblaslapack=yes --download-metis=yes --download-parmetis=yes

MPICH, HDF5 both configured without trouble but flbaslapack wouldn't configure and threw the following error message:

*******************************************************************************

         UNABLE to CONFIGURE with GIVEN OPTIONS    (see configure.log for details):

-------------------------------------------------------------------------------

Cannot request fblaslapack without Fortran compiler, use --download-f2cblaslapack intead

*******************************************************************************

But it worked when I tried the suggested command --download-f2cblaslapack

Will this work for the pflotran install or am I missing something? 

I checked and I have gfortran installed on my machine:

~$ gfortran --version

You could try adding:  --with-cc=gcc --with-cxx=g++ --with-fc=gfortran

Sounds to me like you do not have gfortran installed as the message states “Cannot request fblaslapack without Fortran compiler”.

I reinstalled homebrew and gcc. 

$ brew --version

Chip: fortran 7.2 may not work. You might try 7.1 which I am using on Hi Sierra:

gravenstein:documentation lichtner$ gfortran --version

Please email the $PETSC_DIR/$PETSC_ARCH/lib/petsc/conf/configure.log (there is likely a link to it in PETSC_DIR) to pflotr...@googlegroups.com and petsc...@mcs.anl.gov.  We have many Mac users who can help, but we need that info.

Thanks, Peter. I'll give that a try. 

Glenn, I just emailed the configure.log. 

Thanks,

Chip

I don’t know if this is useful, but last time I tried to install pflotran on a new mac, I discovered that gfortran does not automatically get installed with gcc. Using macports you need to do this:

sudo port install gcc49 +gfortran

 

You may also discover at some point that you don’t have cmake – you can get it with macports, too:

sudo port install cmake

 

Homebrew is probably similar.

I ended up wiping my computer and starting from scratch. 

Now I get PETSc and pflotran to compile. But when I run:

 ~/pflotran/src/pflotran/regression_tests$ make test 

after installing pflotran I'm getting between 16 and about 63 fails, depending on which PETSc config options I used. I tried the PETSc config three different ways (no errors or issues with any of these) and get different regression test fails with pflotran. Seems like fewest errors are with the following PETSc configuration

I'll make a new post in case anybody else is having similar issues on MacOS High Sierra.
