4 years ago @rickgaiser I've setup the toolchain, ps2sdk and the ports using the for-ps2dev branches. I have also built and installed the freetype2, zlib, libjpeg and libpng ports. However executing ./setup.sh fails when it goes to build the examples with the following.
Welcome to the setup script for gsKit.
This script will attempt to automatically detect the presence of LIBPNG, LIBJPEG, LIBTIFF and ZLIB, and will set up all required environmental variables.
If your libraries are not stored in /usr/local/ps2dev/ps2sdk/ports, please specify the location of the libraries manually.
Performing pre-install cleanup.
Libraries:
-e LIBJPEG detected.
-e LIBPNG detected.
-e ZLIB detected.
-e LIBTIFF not detected.

Performing post-install cleanup.I can't seem to track down where it is trying to include crt0.o but even so it should be able to find it since it is now in the ee-gcc lib folder.

These PR series move libc from ps2sdk to newlib:
1: File and directory functions (both fio and fileXio) are now handled by newlib, tranparently. With the following functions supported: -- close/open -- read/write -- lseek -- ioctl -- unlink (remove) -- link (rename) -- mkdir/rmdir -- stat -- opendir/closedir -- readdir -- rewinddir
Existing code must be modified to use these standard posix function names instead of calling fio* fileXio functions directly, becouse of an incompatibility between newlib and the ps2 file handing. For this reason existing code will provide an error when including ps2 headers that should not be used:
For some applications however, using the fio/fileXio functions directly may still be needed (for instance when mounting partitions). By defining 'NEWLIB_PORT_AWARE' before including these headers this is still possible. As far as I know the only incompatibility it with opening a file. The flags, like O_RDONLY, are incompatible and must be changed to FIO_O_RDONLY.
2: time function is implemented, returning the UTC time. Using the stat function the times from files can also be returned in UTC format.
3: nanosleep is implemented. It sleeps using SetAlarm. Then busy waits the last nanoseconds, resulting in both a lot of free cpu time, and a very accurate sleep time.
4: The linkfile has been moved to the binutils port, and crt0.s has been moved to newlib port.
5: The newlib port is upgraded from 1.10 to 1.14. This adds (amongs other things) wchar support, needed by some applications like uLE. Upgrading to newer versions resulted in a lot of compiler issues. Perhaps newlib can be upgraded to 3.x when the compiler gets updated.
The end result is that porting new applications to the ps2 will become a lot more easy. Or sometimes they will just run.
Special thanks to @fjtrujy, the creator of the PS2 RetroArch port, for making this possible.
This PR series consists of ps2toolchain, ps2sdk, ps2sdk-ports and gsKit to get a working newlib toolchain. This is the gsKit PR. It fixes 1 small bug, and the rest is for posix/newlib compatibility.
