Re: Hi, all,

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 422-6466

Now following the suggetion of Carmelo,  I got a working gcc / g++ - uclibc=
=20
based tool-chian for my sh7203 based board.
About libiberty compilation I had a lot of problems related to the missing =
of=20
target specifig compiling option (-mb, -m3e, ...) at the moment of cross=20
compiling of the librery.
I solved the problem manually into the make file, but each time you=20
reconfigure the problem appears again obviusly.
I can compress the tollchain source dir ad put on our fpt server. I' not so=
=20
smart doing patches and I think it is better that a guy starter than me giv=
es=20
a look at my work before considering it good also for others.

Keiram let me know if you like to download from our server so that a send y=
ou=20
username and passwrod for a temporary account.

P.S.
I got on the trget Hello World!!! in c++.
This give me the capabiliti of developing on target usign alse c++ GUI =20
framework based on libSDL.org

Best regards.
