[Plplot-devel] Building plplot in Windows with Intel Fortran Compiler

[Jeremy N. <jrn...@gm...>]

Hi,

I would like to get plplot built in windows with intel fortran bindings
using the Visual Studio command line.  I can get build files generated via
CMake if I turn off fortran bindings, but if I enable fortran I always get
an error when running CMake.  I have tried NMake, Ninja, and Visual Studio
2022 generator files.

In initial troubleshooting to see if this is a more general problem, I came
across this note on the plplot site:

*Intel Fortran*
If you use Intel Fortran, the solution/project files may cause errors when
building. These affect only the Fortran libraries and examples. It is due
to a small bug in CMake that should be fixed with the next release.

Was wondering if anyone had any more information on this, such as what bug
it is, what version of CMake it might be fixed in, and whether there is a
workaround?  I don't know CMake at all, but if I know there is some hope to
get tthis working I can give it a shot.

Some details if anyone cares:
-I am using CMake 3.26-msvc

For NMake, used this command
cmake .. -G "NMake Makefiles" -DBUILD_TEST=ON -DBUILD_SHARED_LIBS=ON
-DPKG_CONFIG_EXECUTABLE=C:\gtk-build\gtk\x64\release\bin\pkg-config.exe
-DCMAKE_INSTALL_PREFIX=C:\usr\lib\plplot -DENABLE_fortran=ON

Error I get at end

What I use for Visual Studio IDE
cmake .. -G "Visual Studio 17 2022" -Ax64 -DBUILD_TEST=ON
-DBUILD_SHARED_LIBS=ON
-DPKG_CONFIG_EXECUTABLE=C:\gtk-build\gtk\x64\release\bin\pkg-config.exe
-DCMAKE_INSTALL_PREFIX=C:\usr\lib\plplot -DENABLE_fortran=ON

Error I get (Truncated as it repeats several times at the end)

CMake Error in bindings/fortran/CMakeLists.txt:
  Evaluation file to be written multiple times with different content.  This
  is generally caused by the content evaluating the configuration type,
  language, or location of object files:
