Hello, I am trying to install FreeFEM v 4.6 on my mac (macOS Big Sur version 11.0.1) via the terminal using the source code, and I come across this issue while trying to configure PETSc: > # =============================================================================== Configuring PETSc to compile on your system > > ## TESTING: checkFortranCompiler from config.setCompilers(config/BuildSystem/config/setCompilers.py:960) \*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\* UNABLE to CONFIGURE with GIVEN OPTIONS (see configure.log for details): > > Fortran compiler you provided with --with-fc=/usr/local/bin/mpif90 cannot be found or does not work. > Cannot compile/link FC with /usr/local/bin/mpif90. > > * * * > > make: \*\*\* [petsc-3.13.0/tag-conf-real] Error 1 I am not sure how to properly complete installation.

Please try again with FreeFEM 4.8 and let me know if this is fixed. If not, please attach _both_ `config.log` and `3rdparty/ff-petsc/petsc-3.14.2/configure.log`. ---

Hello, I tried installing v4.8 and I was able to successfully configure PETSc; however I run into a different issue trying to build the FreeFEM library and executable. I have attached a screenshot of the terminal output. Thank you. ![image](https://canada1.discourse-cdn.com/flex030/uploads/freefem/original/1X/6da227034fc0eda521fb464e82537dddac6fdd33.png) ---

You should be able to configure with `--disable-freeyams` to fix this issue. ---

Okay. Which config file should I change to implement that command? ---

`config.param`, then `./reconfigure`. ---

I tried that but it’s not working either. It says it’s an unrecognized option: > configure: WARNING: unrecognized options: --disable-freeyams ---

Sorry, please try `--disable-yams` instead. ---

I think that helped, but now I’m trying to run examples and I get this error message: `dyld: Library not loaded: @rpath/libhdf5.103.dylib` ---

You have some HDF5 files lying around which have been picked up by configure. Please also add `'--without-hdf5'`. ---

Hello @prj , I have another issue compiling PETSc - this time on a linux system. The error seems to be an issue in compiling PTScotch. I have attached the screen output as well as the config.log file to aid in debugging. Thank you. ![Screen Shot 2021-04-26 at 2.25.52 PM](https://canada1.discourse-cdn.com/flex030/uploads/freefem/original/1X/13a39398965947a844d280cec8d22ed710497d9a.png) [config.log](https://community.freefem.org/uploads/short-url/eIYxgZBHSWWYudRLmrlVtSLGkUH.log) (416 Bytes) ---

And yet you are still not attaching the proper `configure.log` file… I need the one from `3rdparty/ff-petsc/petsc-3.15.0`. ---

My apologies. Here is the correct file.[configure.log](https://community.freefem.org/uploads/short-url/zZ71MYF4RGQECTqvV8oMTveMD9y.log) (1.0 MB) ---

You don’t have access to a newer GCC compiler, by any chance? ---

There is a workaround there: [Compiltion errors on Centos 7](https://community.freefem.org/t/compiltion-errors-on-centos-7/872), but you GCC compiler is very old, so you’ll likely run into other issues. ---

I modified the config.param file to include `'--disable-mmg'`and `'--disable-parmmg'` and recompiled and tried `make petsc-slepc` again, but the same error seems to occur. I’ve attached the configure.log file again in case it is different the time. [configure.log](https://community.freefem.org/uploads/short-url/4KnItJCH9ZYWOhee1qeFRse4SG.log) (770.5 KB) ---

Sorry, I didn’t link the proper answer for this particular error, here it is: [Compiltion errors on Centos 7 - #3 by prj](https://community.freefem.org/t/compiltion-errors-on-centos-7/872/3) You can remove `'--disable-mmg'` and `'--disable-parmmg'` from your `config.param`. ---

That did fix the PETSc compiling issue, so I `./reconfigure` and everything looks good; however, when I run `make` I get a strange output/error. I’ve attached the screen output and config.log ![Screen Shot 2021-04-26 at 4.26.26 PM](https://canada1.discourse-cdn.com/flex030/uploads/freefem/original/1X/61b86e2be1e905096917ad93cb859a62ca900012.png) [config.log](https://community.freefem.org/uploads/short-url/b4eOwd4HOmg9ZnmLA5myb2tmWbm.log) (191.6 KB) ---

Ipopt error, so you need to add `--disable-ipopt` in `config.param`. [Next page](https://community.freefem.org/t/issue-configuring-petsc-during-ff-installation-on-mac/889.md?page=2)
