Bug 675492 – dev-util/kdevelop:5 needs to be rebuilt after sys-devel/clang upgrade - kdevplatform.shell: Could not load plugin "kdevclangsupport" , it reported the error: "The clang builtin include path \"/usr/lib64/clang/7.0.0/include\" is invalid (missing cpuid.h...

[Description tk+gentoo 2019-01-15 14:24:10 UTC]

When upgrading sys-devel/clang without rebuilding kdevelop its kdevclangsupport plugin stops working with the following error message:

kdevplatform.shell: Could not load plugin "kdevclangsupport" , it reported the error: "The clang builtin include path \"/usr/lib64/clang/7.0.0/include\" is invalid (missing cpuid.h header).\nTry setting the KDEV_CLANG_BUILTIN_DIR environment variable manually to fix this.\nSee also: https://bugs.kde.org/show_bug.cgi?id=393779" Disabling the plugin now.

Since this plugin is responsible for parsing, syntax highlighting and autocompletion of c/c++ code, kdevelop is more or less useless to c/c++ programmers without this plugin.



Reproducible: Didn't try

Steps to Reproduce:
1. Install dev-util/kdevelop
2. Install another version of clang than the one previously installed (downgrade should "work" too)
3. Open c/c++ project within kdevelop
Actual Results:  
Parsing, syntax highlighting and autocomplete not working

Expected Results:  
A working c/c++ IDE

This is odd, we do use the slot operator on clang in kdevelop which is supposed to automatically trigger a rebuild. Could you please attach 'emerge --info'?

Created attachment 570694 [details]
emerge --info

Thanks for comming back to this.

This truely is odd, since I though about an forgotten = operator while filing this bug. Maybe there is an obvious bug in my emerge --info.

I have never run into this problem yet. Is this bug still a thing?

I haven't seen it since, either.

I forgot about this bugreport and wasn't aware, that I can mark it resolved...
