Hi Rafael,
I am currently trying to incorporate the patches you sent, but I am running
into a problem with Octave. Here is the start of a whole series of error
messages:

I have no idea how to solve this, so I am hoping you or somebody else familiar
with Octave and SWIG can give me a few pointers, or better still, a patch to
solve this.
For your information:
- SWIG: version 4.0.2
- Octave: version 6.4.0
- I am building this under Cygwin with all the packages updated to the current
versions.
By the way, under Cygwin I do not seem to have a useable Ada compiler, so I
cannot test the changes that you and Nicolas suggested. But to keep them in
line with the rest, I have now implemented the building of the static library
as:
if(ENABLE_ada_static)
set(ADA_lib_type "STATIC")
else(ENABLE_ada_static)
set(ADA_lib_type "")
endif(ENABLE_ada_static)
# target_link_libraries used in special way below so avoid using it inside
configure_library_build.
configure_library_build(plplotada ${ADA_lib_type} "${plplotada_BODY_SRCS}" ""
"${LIB_INSTALL_RPATH}")
so that, if you add the option "-DENABLE_ada_static=ON" to the CMake command
line you will get the static library. So, there will be either a static or a
dynamic (shared) library.
I have not checked in these changes yet, but this is what I intend to do.
Regards,
Arjen

Dear PLplot developers,
SWIG support for Octave 6.0 was broken, but this has been fixed in release 4.1.
I am therefore planning to reintroduce the plplot-octave package in Debian.
When compiling the package against Octave 7, several warnings regarding
operators .- and .+ are issued, like this one:
warning: the '.-' operator was deprecated in version 7 and will not be
allowed in a future version of Octave; please use '-' instead;
Please, find attached to this message a patch that fixes the problem.
Best,
Rafael Laboissière
