Compile Errors when building Code::Blocks source

This script will copy all needed resources (like images) to the right place. I think this is the reason for the missing symbols?  I can't find a error in your screenshot... They are all disabled, because no project is loaded?

probably the same as: https://sourceforge.net/p/codeblocks/tickets/387/
@obfuscated:Does this come from the symol browser?

You can disable the symbol browser by Settings->Editor->Code Completion->Symbol browser->Disable symbol browser (this is only from memory, the actual names can alter, but this should give you a hint where to look)

both errors come from codeblocks? So wxWidgets compiles fine? Funny, i never saw any errors like this on compiling codeblocks...
what is the command line you compiled wxWidgets with?

The wxRE_ADVANCED is because he failed to build wxWidgets using the builtin regex.
Add wxWidgets configure option

--- Code: -----with-regex=builtin

--- End code ---

Note: The CB dev team should fix this so the option is NOT needed; because in the past, Mac users tended to NOT use wxWidgets with builtin regex.

The abs is fixed by a small patch. IIRC, a newer compiler causes the error.

Patch for abs issue under GCC 6.

FYI if you use the --prefix=/some/path/to/codeblocks    for configure of both wxwidgets and codeblocks, you can easily use codeblocks with wx28 and other apps with another version of wx.
That is what I currently do for testing code with both wx28 and wx30 : i simply use 2 separate directories for both codeblockses.
