[winGRASS] Compile GRASS 5.3 in cygwin: can't find includes

[Stefaan Lhermitte]

 Dear GRASSians,

Im trying to complie GRASS 5.3 in the Cygwin environment but with the 
specific ODBC, FFTW and proj features included. I've checked all 
requierements and installed the FFTW and Proj features;

When I run:
./configure --without-postgres --with-odbc-libs=/usr/local/lib 
--with-fftw-includes=/usr/local/fftw_3.0.1/include 
--with-fftw-libs=/usr/local/fftw_3.0.1/lib 
--with-proj-include=/usr/local/proj_4.4.8/include 
--with-proj-libs=/usr/local/proj_4.4.8/lib

I get the following error message:
Unable to locat FFTW includes

I don't know what id do wrong since i specify the FFTW include  and the 
file fftw.h is in that folder.


I the config.log, The following can be found:

configure:9516: checking whether to use FFTW
configure:9535: checking for location of FFTW includes
configure:9561: checking for fftw.h
configure:9569: gcc -E  -I/usr/local/fftw_3.0.1/include  conftest.c 
 >/dev/null 2>conftest.out
configure:9565:18: fftw.h: No such file or directory
configure: failed program was:
#line 9564 "configure"
#include "confdefs.h"
#include <fftw.h>
configure:9597: checking for dfftw.h
configure:9605: gcc -E   -I/usr/local/fftw_3.0.1/include  conftest.c 
 >/dev/null 2>conftest.out
configure:9601:19: dfftw.h: No such file or directory
configure: failed program was:
#line 9600 "configure"
#include "confdefs.h"
#include <dfftw.h>

When I do the same but --without-fftw. The error is identical for: Can't 
locate PROJ includes.

 If i leave both FFTW and PROJ it works, but I specifically want these 
features.

I hope anyone can help me?

Kind regards,
Stef
