After a complete retest of all things, I found this error in development system.
[psptoolchain-20070626-local-src-fixes.tar]: under psptoolchain/scripts folder you must change “unzip” to “tar -jxvf” in both
003-pspsdk-stage1.sh and 006-pspsdk-stage2.sh 7th line.
About OpenGL examples: pspgl examples can be compiled and installed only after libpng,
so psptoolchain-20070626-sdl.tar (where libpng is included) must be compiled and installed before.
So, I updated article with these info, and as I can, I’ll post a new psptoolchain-20070626-local-src-fixes.tar version to include this bugfix.
