OrangeC Unable to compile SOIL2

https://github.com/SpartanJ/SOIL2

I want to compile it into a library, is this command correct?

occ -Wd src/SOIL2/*.c src/common/*.cpp -o SOIL2

BTW, this is the error messages:

I tried another command:

occ -Wd -DSTBI_NO_SIMD src/SOIL2/*.c src/common/*.cpp -o SOIL2

This time it can generate a SOIL2.dll but there are a lot of warnings:

Somehow the stb_image assumes SSE2 (? Might be later SSE revisions) support in-extras like __m128i. Currently, we do not support using SSE2(?) constructs like that.

-DSTBI_NO_SIMD will disable that.

Hmmm... You're right, your second half you point that out.

The SOIL2 issues likely are a result of the warning mechanism detecting an item initialized later that isn't actually used in-context as the GOTO is used as an early exit, so it's a little too trigger happy on those "Uninitialized items after a goto".

so yeah it could be argued that while the goto does bypass those initializations, those initializations aren't used after the target to the goto is reached so it shouldn't cause a warning lol.... i'm going to look at this eventually, but the warnings are benign in this ccase so I'll defer it for a while :smile:
