One of the most annoying things I’m starting to see are bogus way to check for presence of compilers or lib for SPU support…<\/p>\n
Since it is almost the last day of the year here the top annoying pratices list:<\/p>\n
– misnaming: ppu- isn’t a valid prefix, powerpc64-unknown-linux-gnu- is, anyway if is the native compiler gcc would do perfectly, if isn’t someone would provide it to configure so. PLEASE AVOID PPU- <\/p>\n
– misnaming: spu- could be a partially valid prefix, _maybe_ spu-elf- is the correct one . TREAT SPU AS A CROSS TARGET, ALWAYS.<\/p>\n
– bad assumption: I may have a valid spu compiler but _MAYBE_ I didn’t registered elfspe or elfspe2 on binfmt so I cannot automagically run spu binaries or maybe I don’t have spufs mounted. TREAT SPU AS A CROSS TARGET, ALWAYS.<\/p>\n
– picking cflags from env: the spu-elf-gcc and the native gcc may not share the same cflags, make sure your configure could pick CFLAGS_{powerpc,powerpc64,spu} as they fit.<\/p>\n
– hardcoding paths: the ibm and the sony sdk are for non native system with non default cross paths, I know beside gentoo and few other crazy people nobody is using alternate paths, still since maybe native system should be expected and _maybe_ less custom paths could appear, please do not hardcode \/opt\/${STI_SDK}\/blah as include\/lib path in your applications or applications patches (like the one for lame). PLEASE KEEP THINGS CLEAN.<\/p>\n
Here a top5, luckly there aren’t that many annoyances =)<\/p>\n
