I'm using the tutorial at https://netbeans.apache.org/kb/docs/cnd/toolchain.html
This tutorial mostly worked on Windows using 12.4. Worth noting in 12.4: - I found I needed to clean and build the module each time to guarantee changes came through - This meant I needed to add 8.2 support and the C/C++ add-on to 12.4 for each test run, which was a little tedious but workable once I understood this was the necessary cycle. - I created an NBM package as described. This seemed to fail on signing, so I added a self-signed certificate. Perhaps add a link and say if self-signed will work? I don't think signing is mentioned. - toolchaindefinition.xsd is nowhere I have been able to locate. - got as far as "7. If the new tool collection (GNU_tuned) is not shown,..." My current symptoms are that my new module works when I run/debug it, and the NBM package adds, installs, and reasonably demands a reboot each time I uninstall then remove it. It just does not show up in my Tool Collections when I "Restore Defaults" as I would expect. This is all working fine when I 'run' it using the debug copy of NetBeans and the shadow copies of the tool collection descriptors. Can someone tell me what piece of the puzzle I'm missing? Added: I went digging and found %appdata%\NetBeans\12.4\var\log\messages.log. I don't see any serious problem there however:
