Ported to ARM7, compiles but crashes on running. #479

Closed thecosmicslug closed 3 years ago

thecosmicslug commented 7 years ago

I managed to cross-compile cdogs for the steamlink (an arm7 1ghz device with 256mb ram and sdl2 support)

I only had to remove the compiler option " -Winline" to get it running, no other changes but here is the debug log, seems to be loading sound effects before it errors out.

I'm not familiar with ARM7, are you able to run it in a debugger and see what values it's try to free? Does free(NULL) break on ARM7?

@thecosmicslug I've identified a memory corruption bug recently, could you please try again with the latest code?

thecosmicslug commented 7 years ago

Still segfaults shortly after running, the only option I changed to get compile to succeed was removing -Winline from the makefile... could that be affecting anything?
