It seems there are compiler options in the template that i don't see anywhere in the Build Options
I followed these instructions to get my wxWidgets-2.6.1 libs compiled with MS Free Tools.
http://wiki.wxwidgets.org/wiki.pl?MS_Free_Tools_And_WxWidgetsThen I did the following from the CodeBlocks wiki instructions (paraphrased slightly from the Post compilation steps for for vc++ toolkit 2003 compiler):
http://wiki.codeblocks.org/index.php/Compiling_wxWidgets_2.6.1_to_develop_Code::Blocks_%28MSW%29C:
cd \wxwidgets-2.6.1\build\msw 
nmake -f makefile.vc USE_XRC=1 SHARED=1 MONOLITHIC=1 BUILD=release UNICODE=0 VENDOR=cb clean 
nmake -f makefile.vc USE_XRC=1 SHARED=1 MONOLITHIC=1 BUILD=release UNICODE=0 VENDOR=cb 
cd \wxwidgets-2.6.1\lib; mkdir codeblocks_vc; cd ..\vc_dll; move * ..\codeblocks_vc; move msw ..\codeblocks_vc 
  I think move * ..\codeblocks_vc is supposed to be move * codeblocks_vc by the way, I am at a computer where I can't verify that at the moment, but anyway I think I figured that part out and it seemed to work. I don't have any interest in building codeblocks itself, by the way, so  I am not sure if the above was necessary
Then I try to open up a blank wxWidgets project and try to compile without editing it and get the following
Project : wxWidgets application 
Compiler : Microsoft Visual C++ Toolkit 2003 (called directly) 
Directory : C:\keep\private\KODE\ 
-------------------------------------------------------------------------------- 
Switching to target: default 
cl.exe /nologo -pipe -mthreads -fno-pcc-struct-return -fno-rtti -fno-exceptions -D_X86_ -DWIN32 -D_WIN32 -DWINVER=0x0400 -D__WIN95__ -D__GNUWIN32__ -D__WIN32__ -DSTRICT -D__WXMSW__ -D__WINDOWS__ /I"C:\Program Files\Microsoft Visual C++ Toolkit 2003\include" /I"C:\Program Files\Microsoft SDK\include" /c main.cpp /Fo.objs\main.obj 
main.cpp 
cl : Command line warning D4002 : ignoring unknown option '-pipe' 
cl : Command line warning D4002 : ignoring unknown option '-mthreads' 
cl : Command line warning D4002 : ignoring unknown option '-fno-pcc-struct-return' 
cl : Command line warning D4002 : ignoring unknown option '-fno-rtti' 
cl : Command line warning D4002 : ignoring unknown option '-fno-exceptions'
Then I'm thinking fine, I'll just remove those options from my project and probably from the default wxWidgets template.
But I can't find those build options in my project build options, as if they are hidden somewhere or hard coded.
Snooping a little further I see a file wxwidgets.cbp in the c:\program files\codeblocks\share\codeblocks\templates:
<?xml version="1.0"?>

   It looks like the wxwidgets-static.cbp is the one I want since I would like to use the static (and multilib) version of wxWidgets-2.6.1.
Where are those compiler options like -pipe hidden, or am I supposed to manually edit the wxwidgets.cbp to change thel wxwidgets project defaults as needed. That looks easy to do, just want to make sure that is the standard way.
