Re: [Plplot-general] Gfortran PLplot5.15.0 OSX15.2

[Korzennik, S. <sko...@cf...>]

Hi Paul,

  A colleague of mine, and nevertheless a friend, was in the same
predicament. I installed gfortran and psplot for him successfully. Note
that I am more of a Linux person than a MacOS. Here is what I did
- installed brew
- installed gfortran with brew
- downloaded psplot from source and build it w/ cmake and make
- downloaded GSL with brew
- install xquartz to add X support (w/ brew?)
- compiled his codes, that needed some tweaking to adjust to the latest
version of psplot

I wrote Makefile files for him, here is what on looks like for his desktop
Mac Studio running Sonoma 14.6.1

FC = gfortran -std=gnu -ffixed-line-length-132
GSL=/opt/homebrew/Cellar/gsl/2.7.1
LDIR = /Users/gmelnick/plplot/lib-5.15.0/lib
MDIR = /Users/gmelnick/plplot/lib-5.15.0/lib/fortran/modules/plplot
CODE = AFGL_TRANS

code:
       $(FC) -c $(CODE).f -I$(MDIR)
       $(FC) -o $(CODE) $(CODE).o -L$(LDIR) -lplplotfortran

As you can see, the build of plplot was installed in
/Users/gmelnick/plplot/lib-5.15.0/lib, GSL in the cellar
The options to gfortran are needed to accommodate his fortran style.

On his MacBook Pro laptop, running Sequoia 15.2, the Makefile became:

FC = gfortran -std=gnu -ffixed-line-length-132
GSL=/opt/homebrew/Cellar/gsl/2.8
LDIR = /Users/gmelnick/plplot/lib-5.15.0/lib
MDIR = /Users/gmelnick/plplot/lib-5.15.0/lib/fortran/modules/plplot
CODE = AFGL_TRANS

code:
      $(FC) -c $(CODE).f -I$(MDIR)
      $(FC) -o $(CODE) $(CODE).o -L$(LDIR) -lplplotfortran

Note that for his laptop, I had to build psplot from source with gfortran
v13, not v14, and had to install cairo and maybe more to get the
xcairo device to work properly. The xwin device was not behaving the same
way under  OSX15.2 than OSX14.6.1 (gfortran 13.1 vs 13.2).

Also the psplot lib loaded with brew would not support either xwin or
xcairo (interactive devices), hence the need to build psplot from source
(cmake, make, make install, nothing special, besides specifying the
destination for the install, using gfortran-13 for OX15.2 and checking that
cmake find the libs to build the xwin and xcairo devices). Also, the
location of the dynamics libs needed to be specified w/ an env variable to
run (DYLD_LIBRARY_PATH)

As far as creating exec that can be distributed, you need to link
differently (and compile?) to use static libs instead of dynamic ones,
otherwise you will need to distributed the dyn libs too (ldd is the linux
command to show dyn libs info, it may work the same way under OSX?). Check
the doc on gfortran for static linking.

Hope this helps.

    Cheers,
      Sylvain
