C::B removes original extension of precompiled header

(1/3) > >>

p2rkw:
For example file "precompiled.hpp" is pre-compiled to "precompiled.h.gch", but gcc expected "precompiled.hpp.gch", see here: http://gcc.gnu.org/onlinedocs/gcc/Precompiled-Headers.html
I know that precompiled header extension is replaced with extension setted in Compiler->Other settings -> Advanced opts -> Others, but as you can read in gcc manual:

--- Quote ---The name searched for is the name specified in the #include with ‘.gch’ appended. If the precompiled header file can't be used, it is ignored.
--- End quote ---
There's no need to remove original extension, only postfix ".gch" should be added.

PS. I found second usability bug: changes made in Compiler->Other settings -> Advanced opts -> Others enter into force not when you click "ok", but when you reload project.

OS and version please.
Probably simple example project?

Exact steps to reproduce?

p2rkw:
Fedora, svn rev 8926, project in attachment. As you can see in build log all.hpp was compiled twice, because gcc couldn't find all.hpp.gch.

Open test project, build it, then change for example Compiler->Other settings -> Advanced opts -> Others -> PCH extension and rebuild project. C::B will use old pch extension.

Jenna:
The issue happens with extension h.gch and also with hpp.gch, and it does not matter what the real headers ending is, so it is either a compiler bug or the -H option does not work as expected and always show the included headers, even if they are included via pch.

p2rkw:
Heres my build log when I rename all.hpp to all.h and set it as precompiled header:
