[Dev-C++] Problems compiling a simple wxWindows application in Dev-Cpp

[Frank W. <F.W...@wi...>]

Hello,
I got a very misterious problem while I try to compile a simple
HelloWorld wxWindows application with Dev-Cpp.
I compiled wxWindows under cygwin and I'm able to compile the samples
in console mode.
But when I set up a Projekt under Dev-Cpp where I set up the required
pathes for lib and includes and try to compile the app I get the
following error message  for exaple:

-->
 C:\usr\local\include\wx\buffer.h     In constructor `
wxCharBuffer::wxCharBuffer(const char*)':
98 C:\usr\local\include\wx\buffer.h   `strdup' undeclared (first use
this  function)
<--

Similar errors follow but it seems to me that the compiler does not
find the <string.h> in 
c:\cygwin\user\include
Instead he seems to look at "wx\string.h" in c:\cygwin\usr\local\
where my the wxWindows includes were put in after doing "make install"

I will attach my Dev-Cpp makefile and the make output of a comandline
make to compare.

I hope someone can help me because I ran out of ideas.

Thanks in advance

Frank
