Subject: Package building for QNX6
I'm just completed the package description file for QNX6 - qpg, it is like a\
.spec files for Linux. Please place SDL.qpg.in file in the root of the proj\
ect, where .spec file is placed. And sdl12qpg.diff - just adding the SDL.qpg\
.in. The same for the SDL_image. I'm planning to add .qpg files creation for\
all SDL* projects.
As for shared library building for QNX6. It is very hard to improve the exis\
ting libtool code to support QNX shared libraries. Much easyiest is to remov\
e libtool.m4 code from the acinclude.m4 for those persons, who building shar\
ed libraries for QNX6. I'm described all what they need to do with .so under\
QNX6 in the README.QNX file. And 90% of people used the precompiled librari\
es, so I think it is not big problem :)
