Single PCH file for building the CodeBlocks_wx31_64.cbp
ollydbg:
Several years ago, I posted some patches to build CodeBlocks_wx30.cbp which only need to use single PCH, also, we don't need to export unnecessary symbols from the codeblocks.dll. Now those patches are manually applied to the CodeBlocks_wx31_64.cbp and related files.
You can find it here: https://github.com/asmwarrior/codeblocks_sf/tree/small_codeblocks_dll

Hello,
what are these fixes?
ollydbg:
One issue I try to fix is that I don't think it is necessary to export all the symbols from the codeblocks.dll, only a few of them need to be exported, so this can reduce the size of the codeblocks.dll.
Another issue is: I always see two PCH file generated when building. In-fact, we can use only one PCH file for both building sdk target and other src or plugin targets.

This is the old discussion about this issue.

1. In my opinion this PCH stuff causes more problems than it solves. For me even slows the compilation down, because I edit some of the headers included in it very often. But most of these headers are not used everywhere, but I get a full rebuild anyway. I'll be happy to just remove it. Also full rebuilds are serialized on modern machines, because they are waiting on the 2 pch compilations.
2. Your branch contains other changes.
3. You reuse the DLLIMPORT macro for different libs, don't do it. It will cause problems some day.
4. I'm 25% into the process of removing SqPlus.
5. I'm pretty sure you've broken the --disable-pch autotools build, but I have not tested.

My branch has manily two things:
1, PCH related changes, from your point, non-pch build is better, so, we can drop the PCH related changes.
2, some export related changes, I think we don't need to export every symbols from the codeblocks.dll, which makes the codeblocks.dll smaller.

I don't know SqPlus' relatationship with my branch.

I have only Windows build system, so, I can't test it.
