Same here so I pushed it. See <https://sourceforge.net/p/plplot/plplot/ci/cf04f2e6b555edab673a9703cea909d7239ce21b/> for the substantially changed commit message that includes details of the tests I ran. Thanks very much for getting this revised version of your commit to work without generating the segfaults produced by the prior version.
P.s. Latter on I will try to understand how to deploy pyqt5_example.
The missing Python library issue that was previously stopping you can obviously be addressed by installing the right opensuse package. But finding the name of that needed package is more "an art rather than a science". To help you with that "art" here are the equivalent details on my Debian Stable platform. # Find the names of all packages which include a partial filename "libplplot*.so$" # where ".so" with nothing further added is important since it is that exact suffix the linker looks for. irwin@merlin> apt-file search libpython |grep '\.so$' |less There were 17 different possibilities, but one of those libpython3.7-dev: /usr/lib/x86_64-linux-gnu/libpython3.7m.so referred to the development version of libpython3 so I am sure that is the library that is needed, and I do have that package already installed. So I think this result for Debian Stable means you need to install the development version of either the python3 or libpython3 package (depending on how opensuse organizes its package names and designates the name of the development version of those). Of course, opensuse will not have the apt-file application, but it should have something equivalent so that you can associate filenames with the packages (either installed or not installed) that include those files. After a successful build I confirmed that /usr/lib/x86_64-linux-gnu/libpython3.7m.so name as follows: # Find the exact name of that library (at least for Debian Stable after a successful build of the python binding): software@merlin> readelf -d bindings/python/_plplotc.so |grep -E 'PATH|NEEDED' 0x0000000000000001 (NEEDED) Shared library: [libplplot.so.17] 0x0000000000000001 (NEEDED) Shared library: [libpython3.7m.so.1.0] 0x0000000000000001 (NEEDED) Shared library: [libc.so.6] 0x000000000000001d (RUNPATH) Library runpath: [/home/software/plplot/HEAD/build_dir/src:] Hope this working Debian Stable example helps you figure out what to do for opensuse to gain access to that distro's python3 library.
also going to try to see how i can force plplot to build with qt6 and then one will know if this small patch is enough to deal with the next major version of the qt,
Good luck implementing these important Qt6-ready goals for PLplot. Alan __________________________ Alan W.
