[PSP] toolchain and gcc

Hi,

The toolchain-sudo.sh installation defaults gcc 4.2 as compiler.
I think this behaviour is obsolete as the toolchain builds fine under ubuntu with it's default gcc 4.3, and even with fedora's gcc 4.4
Also, this version of gcc tends not to be packaged as newer versions of gcc get released.

To me, this should be removed :

Code: Select all

 ## Temporary workaround for gcc.
 export CC=gcc-4.2

There are bugs in the toolchain. When it is compiled with GCC 4.3 or newer, these bugs cause crashes at runtime.

Hi,

I see 'CC=gcc-4.2' was removed from the install script
so what'sup ? does compiling with gcc>4.2 fully works now ?
I didn't notice any runtime error with fedora and 4.4, although i only use very few, basic stuff, and a little sdl.

Yep, the bug should be fixed by http://forums.ps2dev.org/viewtopic.php?t=12528
and gcc > 4.2 should be OK. Let me know if you run into any problems.

Note that gcc > 4.2 was always OK buffer overflow checks aren't enabled (Ubuntu and OSX at least seem to enable them by default).
