[xrotor] compilation fails: Rank mismatch

[mx212]

The compilation of xrotor fails for me. I tried to install it with an AUR helper using: trizen -S xrotor. I tried manually compiling the source with different Makefile tweaks from https://stackoverflow.com/questions/69772266/compiling-and-running-xrotor-on-ubuntu-20-04, but this didn't change anything for me.
Here is the relevant error message:

I encountered this a while back and haven't yet rolled a fix out. Basically need to edit the makefile to add a flag which will disable the rank mismatch check:

This is what I had in my notes:

sed the makefile with -fallow-argument-mismatch

Thank you for the quick awnser. I added a sed command in the build() function of your PKGBUILD file as follows:

build() {

  cd Xrotor/plotlib
  cp config.make.gfortran config.make
  make libPlt_gfortran.a

  cd ../bin
  sed -i '/FFLAGS/ s|$| -fallow-argument-mismatch|' Makefile.gfortran
  sed -i '/FFLOPT/ s|$| -fallow-argument-mismatch|' Makefile.gfortran
  cp Makefile.gfortran Makefile
  make xrotor
  make jplot
}

This is probably overkill, but it worked for me. I guess only FFLAGS is required, but I didn't check.

Glad that you were able to find a solution.
We actually keep issues open until they are fixed, so I'll reopen this.

I would be ecstatic if you could make a PR with your fix so that we can properly close this issue.

My bad. This is my first fix on github.
It turns out that, indeed, only FFLAGS is required. I created a corresponding pull request.
