I am a fairly experienced programmer in both *NIX & Win32, but I am new to Code::Blocks. I have used the DevC++ environment with wxWidgets successfully in the past. But I recently despaired of ever getting 4.9.9.2 & wxWidgets configured correctly on my system and decided to give Code::Blocks a try. After installing the IDE (at D:\bin\Codeblocks) I with some difficulty got wxWidgets to build - I believe in the Release/ANSI/DLL configuration. I have WxWidgets installed at D:\bin\Codeblocks\wx.
when I create a wxWidgets project using C::B I get an irritating warning
![](http://www/wwrinc.com/pictures/cbWarning.jpg)
that I do not know how to prevent for future sessions, but which I can temporarily correct and live with. I go into project->build options->custom variables and change WX_DIR to "D:\bin\CodeBlocks\wx".
At this point I try to build this minimal application and am rewarded with an effulgence of error messages to the effect:
Project : wxWidgets application
Compiler : GNU GCC Compiler (called directly)
Directory : D:\bin\CodeBlocks\Work\

I know that the source of my problems must be simple, but searching the FAQ's and the documentation and these fora have not yeilded any (understandable to me) solutions. I would appreciate any help anyone can offer.

Extra Info:
========
When I check gcc --version crom a cmd.exe command line the response is:
D:\bin\CodeBlocks>gcc --version
"gcc (GCC) 3.4.4 (mingw special)".
Checking make, I get:
D:\bin\CodeBlocks>make --version
"GNU Make version 3.77, by Richard Stallman and Roland McGrath."
Checking mingw versions from the command line (cmd.exe) I get:
D:\bin\CodeBlocks>mingw32-gcc --version
mingw32-gcc (GCC) 3.4.4 (mingw special)
and
D:\bin\CodeBlocks>mingw32-make --version
GNU Make 3.80
all of these commands are following the system path to locate the desired executable. Executing the same commands from the MinGW command line from /d/bin/CodeBlocks gives me exactly the same results.
