I get a toolkit working with cygwin thanks to you \o/
Since I got some difficulty (3 day to make it works -_-) I give my nooby contribution to your post.
I first have some problem with gmp include and after that with ncurses.
So I get cygwin and selected all this pakage
Devel
Math -> gmp
Math -> mpfr
WEB ->wget
I entered in the search box "curse" and selected all concerning ncurses
I entered in the search box "info" and selected all concerning ncurses
So I think if you have problem with a pakage, restart the cygwin launcher make a search and select all the package.
After that I could not connect to the svn link, so I try this one :
svn co
http://psp.jim.sh/svn/psp/trunk/psptoolchainI do the following in cygwin :
echo "export PSPDEV=/usr/local/pspdev" >> ~/.bashrc
echo "export PATH=\$PATH:\$PSPDEV/bin" >> ~/.bashrc
Since ncurses is not in the good directory, I just copy and past the wole directory :
C:\cygwin\usr\include\ncurses
into the :
C:\cygwin\usr\include
and I launch the psptoolchain script :
cd ./psptoolchain
./toolchain.sh
And it works (at least I compiled a little program and make it works on my PSP in 5.5G) !!
