Couldn't Allocate Heap, win32 error ...

[Manveru]

I solved this bug first with a register fix program, but i forgot its name. After that, i solved this error instaling PC Tools Firewall (it is not a joke). Casually the errors disappeared and after some time i discovered it was because of the firewall. Just disabling this firewall causes the errors to return (using windows 7 x64)

I think the version which produce best code for m68k is around 2.8.xx but that is definitely too old and some nice compiler features are missing.
I think version 3.4.6 is "good enough", 4.X or new (5.X) produces poorly optimized code and generally later versions are worst :-/ That is just due to GCC adapting the code generation structure to newer CPU architecture which basically broke optimization done for older architecture as the 68000.

i wonder if we could fork latest stable gcc and make it work like 2.8, so we get the best code, no compatibility problems and bunch of new features
nonsense?

I think that is just impossible, there is too much differences and i guess the code generation part is somehow linked to the compiler new features as well...

djcc's instructions (set winXP compatibility to make.exe) helped me with sgdk lib compilation, thanks a lot! But this does not work to a game project for some reason.

When i try to build a game project with xp-compatible make.exe/admin, im getting following errors:
"in function _start_entry, undefined reference to main"
"in function _reset_entry, undefined reference to main"

And when i do it without admin permissions, it does nothing, just like this...

If i disable "XP mode", couldn't allocate heap error comes back and appears in 99,9% cases.
This is the main reason, why i just can't use sgdk with windows.
There are cases, when i couldn't build my project for 10 times in a row. I give up.

Also, if somebody does have gcc 3.4.6 or 2.8 sources, can i have it too? =^•^=
Maybe i could accidentally fix heap issue
Thanks! <3

I don't have the sources anymore, but i still have a sitting GCC 4.X binary somewhere. I don't think they are affected by this annoying memory allcoation crash issues.

[ronin68k]

I don't have the sources anymore

Could those help sgdk development or this is completely useless for now? Also, what features are we missing with 2.8?
Sad, we cannot also use clang.

[Stef]

SGDK makefile uses some switchs which may not be supported by GCC 2.8, and even GCC 3.4.6 does not support inlining correctly, i guess it would be even worst with 2.8 but honestly i'm intrigued and will probably give a try as i know GCC 2.8 provides the best code for 68k target
Thanks for the link !

Glad to help you, Stef! Thank you for sgdk, you made my dreams of genesis coding come true.
Hope, you will get 2.8 working
