SGDK can not be compiled on modern non-Windows machines using GCC 6 #178

Closed bferguson3 closed 3 years ago

bferguson3 commented 4 years ago

GCC 6 is old and has too many issues at this point to successfully compile on anything other than an x86-32 compatible Windows machine.

I've attempted both the Mac and Linux gendev branches to no avail. I also tried compiling on the new Raspberry Pi 400. I've encountered a variety of errors on both, the most notable are Specified CC_FOR_BUILD doesn't seem to work on MacOS and something similar to -1 cannot be coerced to null on raspbian.

32-bit dependencies must be removed moving forward - ARM64 is picking up steam, and right now the only way to make Genesis games with this SDK is on an i686 Windows 10. Seems odd, no?

GCC 7, 8 and 9 are all maintained still, whereas 6 is not. Please abandon it? Please?

Stephane-D commented 4 years ago

@bferguson3 Nothing prevent to use newer GCC. I embed GCC 6.3 binaries for Windows platform for convenience but you can probably modify / patch GenDev project so you can build newer GCC without any issues. I know that somepeople use SGDK with newer GCC builds (as GCC 9).

Does it have any effect on the resulting binary performance wise?

Stephane-D commented 4 years ago

GCC >= 6 are about the same level of performance. From different tests it looks like GCC 6.x still generate a better code for 68k target but the difference isn't important

Can be closed (any recent GCC version can be used).
