That commit breaks the build. Ugh. So let me remark on that more urgent issue before answering your other questions. Here is the message I get if attempting to build x15 /usr/bin/ld: CMakeFiles/x15.dir/x15.cc.o: undefined reference to symbol 'c_plfill' /usr/bin/ld: note: 'c_plfill' is defined in DSO /home/software/plplot/HEAD/build_dir/src/libplplot.so.12 so try adding it to the linker command line /home/software/plplot/HEAD/build_dir/src/libplplot.so.12: could not read symbols: Invalid operation collect2: error: ld returned 1 exit status What is going on here is your change has made the C++ examples depend explicitly on our core C library (which we should have anticipated in discussions, but we all missed this implication) so the linking for those examples has to be changed to include the core C library directly. Please also reread my remarks concerning pltr[0-2] because there are similar linking implications for use of the C callback in those cases as well. Since this is a new linking implication we have not considered before please consult with Andrew to be sure that using the C callbacks (which requires every C++ user of plshade and plshades change the linking on their application) rather than his preferred approach is the right way to go here. For now, I will fix this linking issue for all examples that use the C plfill callback so that others using our official repository can build again, but if/when you decide in consultation with Andrew to try his approach instead, we should remove this linking fix to avoid overlinking.
