SUMMARY kdoctools fails to build on systems who use (i) zsh, (ii) antigen and (iii) zsh-autosuggestions due to a regression in the DocBookXSL finding algorithm used by cmake Possibly related to #373896 STEPS TO REPRODUCE 1. Install antigen, make sure you have zsh-autosuggestions on PATH 2. run `kdesrc-build kdoctools` 3. Look at cmake.log and build.log OBSERVED RESULT The build fails, as it tries to search for the folder manpages in ~/.antigen which is where its not supposed to look for DocBookXSL. Possibility is that there is a VERSION file in ~/.antigen/bundles/zsh-users/zsh-autosuggestions/ which makes cmake think that it _is_ the DocBookXSL directory; The build subsequently fails EXPECTED RESULT The build should complete successfully SOFTWARE/OS VERSIONS Windows: macOS: Linux/KDE Plasma: Arch Linux / 5.20.3 (available in About System) KDE Plasma Version: 5.20.3 KDE Frameworks Version: 5.76.0 Qt Version: 5.15.2 kdoctools @ 8609659ba44e49af8b53f6d4bd6de06c002ee477 ADDITIONAL INFORMATION
The FindDocBookXSL.cmake code tries first to look into several paths for lib/lib.xsl, and then it tries to find it VERSION is another set of paths which are build by items of CMAKE_SYSTEM_PREFIX_PATH and share/xml/docbook/xsl-stylesheets-* , so it looks to me unlikely that a random VERSION file may affect the process. This is a very specific issue on a very specific platform, and it may require people with the proper environment knowledge to debug it. As a starter, please attach the compilation logs and the exact error messages.
I have attached the build.log and cmake.log for your reference. It seems like CMAKE searches my $PATH for DocBookXSL; my $PATH includes ~/.antigen/.../zsh-autosuggestions which might be a pointer. I am not sure why it selects ~/.antigen/.../zsh-autosuggestions. I can clean build it, if I pop ~/.antigen/.../zsh-autosuggestions from $PATH, but it might imply that some checks or the path to DocBookXSL is to be refined perhaps https://people.sugarlabs.org/~srevinsaju/dl/cmake-2020-11-30.log https://people.sugarlabs.org/~srevinsaju/dl/build-2020-11-30.log
