yes, I have read this post, still could not fix the problem
http://forums.codeblocks.org/index.php?topic=2218.0when I try to built a static library, new nightly build, Winxp-pro
this is error output when I compile a static lib project (a simple static lib project auto-generated by cb)
-------------- Build: Debug in slib ---------------
Compiling: main.c
Linking static library: libslib.a
ar.exe: libslib.a: No such file or directory
Process terminated with status 1 (0 minutes, 0 seconds)
0 errors, 0 warnings
"no such file or directory", what does this mean? could not find ar.exe or the object files?
(1) the problem occurred after I manually delete all keys of code::blocks in registry table when I tried to have a clean new install. 
also cleaned the confiugreation folder under the "document and setting\ ... " folder,   
(2)cannot repeat this problem in another machine, I compared the cbp files, exact the same, 
I guess the problem is caused some setting saved in registry table. just wonder how to clean cb completely from the system,
(3) the following is a project file generate by creating a new static lib, don't know if something wrong here
(4) when I re-install the 
rc2, no such problem, 
thanks
