Fortran interface for matio

[onyukim]

Hello,

I have found that Fortran interface for matio cannot be compiled.
I would be grateful if you could fix that.

[tbeu]

I am afraid the Fortran interface is not well maintained. I would be very glad if you could figure out what the problem is.

[onyukim]

Thank you for the response.

• Configurations for src/fortran/Makefile.am and src/fortran/matio_t.inc.in are missing in configure.ac
• Configurations for a Fortran compiler is also missing in that file.

I added some lines as shown below. However, I don't know whether it is correct because of my lack of knowledge about autoconf and automake.

After ./autogen.sh and ./configure, the desired files were generated, but make in src/fortran failed to compile the interface.
I attached the message given by a compiler (I use Intel C and Fortran compilers). It appears that something wrong happened in compiling matio_internal.c.

fd2ca03 removed the Fortran support from the configure and build options. I do not know why it was removed and will see if I get it running again.

[tbeu]

There is now a branch fortran with reverted fd2ca03. However it does not build. Also, the original developer of matio did not yet reply on my mail asking for support.

[onyukim]

Thank you so much for your consideration.

[tbeu]

Thanks to the original author of matio, I got this one running with gfortran

git clone https://github.com/tbeu/matio --branch fortran matio_fortran
cd matio_fortran
./autogen.sh
./configure --enable-fortran
make
./test/test_matf

However, linking now fails if no fortran compiler is found or --enable-fortran=no. I've already spent 3 hours trying to fix the FCLINK, but I still failed with autotools. 😞

[onyukim]

Thanks for your effort to fix that problem.
I hope that matio is available in Fortran.

[tbeu]

Does this mean branch fortran works for you?

[onyukim]

In my case, I have no problem with compiling.
I cannot have tested that the interface work well because I have no time to do that in recent days.

I will report to you the result after testing the interface.

[tbeu]

I will report to you the result after testing the interface.

@onyukim Did yiu succeed to test the interface meanwhile?
