Installation on M1 mac

GROMACS version: GROMACS 2021.4
GROMACS modification: No
Here post your question
Hi,
I am following this protocol:

  1. Get the latest version of your C and C++ compilers.
  2. Check that you have CMake version 3.13 or later.
  3. Get and unpack the latest version of the GROMACS tarball.
  4. Make a separate build directory and change to it.
  5. Run cmake with the path to the source as an argument
  6. Run make , make check , and make install
  7. Source GMXRC to get access to GROMACS
    Installation guide — GROMACS 2021.4 documentation

It fails at 6 when I do ‘make’
checking size of size_t… configure: error: in /Applications/gromacs-2021.4/build/src/external/build-fftw/fftwBuild-prefix/src/fftwBuild-build': configure: error: cannot compute sizeof (size_t) See config.log’ for more details

Any idea of what to do would be greatly appreciated.

Hi,
you can try to use -DGMX_BUILD_OWN_FFTW=ON
\Alessandra

Dear Alevilla,
Thanks for your input, but it does not work.

I do (point 5)
‘cmake … -DGMX_BUILD_OWN_FFTW=ON -DREGRESSIONTEST_DOWNLOAD=ON’
and that runs fine.

It fails at 6 when I do ‘make’
checking size of size_t… configure: error: in /Applications/gromacs-2021.4/build/src/external/build-fftw/fftwBuild-prefix/src/fftwBuild-build': configure: error: cannot compute sizeof (size_t) See config.log’ for more details

‘make -DGMX_BUILD_OWN_FFTW=ON’ is not possible.

Problem is occuring in the fftw configure before build. It is possible that the automatic configure/build is not suitable for M1, or to your compilation environement. Perhaps you could build fftw separately to isolate what is causing it.

Get the fftw source from their website, then ./configure --prefix ~/(some directory to install to) --enable-single --with-pic --disable-fortran --disable-mpi --disable-threads --enable-shared --disable-static, then make. (NB: this is not necessarily the best build option for the platform in term of optimization)

if perchance the problem does not appear when building ffttw standalone, you can change the gromacs cmake options to -DGMX_BUILD_OWN_FFTW=OFF -DFFTWF_LIBRARY=/{prefix where fftw is installed}/lib64/libfftw3f.so -DFFTWF_INCLUDE_DIR=/{prefix where fftw is installed}/include . If so, you may want to rebuild fftw with the appropriate optimization flag (probably something like --enable-generic-simd128 or --enable-neon ?).

Hi, thanks for the input.
Indeed it gives the same error when trying to install separately.
But I do not understand the problem here too.

fftw-3.3.10 % ./configure --prefix /Applications/fftw-3.3.10/fftw --enable-single --with-pic --disable-fortran --disable-mpi --disable-threads --enable-shared --disable-static

configure:16072: checking for uint32_t

Thanks!

Unfortunately, none of these errors are actually errors. (some of the tests the configure script runs are actually expected to fail, so searching for “error” do not necessarily give results. For instance here, sizeof((size_t)) should not compile - if it did, this means size_t is not a type but a variable, which is the actual problem the test is trying to detect)

Can you search in config.log for “checking size of size_t” (full line “configure:16363: checking size of size_t”) and post the surrounding ?

For reference, you can post code verbatim like so:

```
the code
```

Oh Sorry!
Please find enclosed the config.log part where the error arise

This sounds like your compiler install has some problem ( uint8_t and other are built-in type, this should not occur). Seems very similar to the following stackoverflow post or this github post, i.e. interation between OS upgrade and homebrew/xcode.

I’m not knowledgeable on Mac OS, so cannot advise about any of the proposed solutions. If a solution does solve your problem, please write back what worked.
