[GRASS-dev] WinGRASS Wiki Hacking

[Marco Pasetti]

Hi Glynn,

I'm stretched in time (electronic systems exam ongoing) , but I try to join 
the thread a bit;

good to know; probably something has changed since I tried the first time to 
use them.
in the past I had problems to build GDAL with external libs and enabling 
jpeg support in libtiff, using libjpeg from gnuwin32, obviously.

it compiles without changes for me

it works as libfftw3-3 for me, but I compiled it by myself; IIRC the 
gnuwin32 build has been configured differently than mine... but I'm not sure 
about that

since it's very fast to compile, also on MinGW, I would higly prefer to 
build from source, as I currently do

I didn't spent much time on it (I tried only few times to let it work 
without success, but I really didn't seriously try...), but I guess that the 
soultion would be here: http://wxconfig.googlepages.com/

I'm currently providing a MSYS build environment, with all the libs/bins I 
build from source for GRASS, but they are "all together"; I could provide 
"divided" binaries for each library, if you prefer.
On this w-e I'll send to Markus an updated version of the MSYS build env, 
with some upgrades and the add of the jpeg lib and support. Along with it 
I'll upload (to release) a new winGRASS binary release (the fourth for 
6.3.0)

Marco
