Open2x Sdl_svg Compile Error

[brainsick]

I'm getting an error when compiling SDL_svg as pulled from the open2x SVN repository today:

The only thing that jumps out at me is the fully-qualified path for mathinline.h; shouldn't it be referring to the headers from the open2x toolchain?

todd@silver:~/open2x$ find ./ -name 'mathinline.h'

./build/toolchain/glibc-2.3.5/sysdeps/generic/bits/mathinline.h

Everything else (toolchain, libs) compiled fine; it's just SDL_svg that's giving me problems. Any ideas?

 

[Mudi]

Just comment out SDL_svg in the makefile, I don't know why that is still there, I've never gotten it to build right.

 

[brainsick]

That's what I ended up doing, but I've seen reports of others getting SDL_svg to compile correctly.

I'm fairly convinced it has to do with it trying to use mathinline.h from /usr/include/bits; I'll try to chase that down later today. By nature, I'm lazy and was hoping someone already had an answer.

 

[torpor]

my answer: use libsvg/libsvg-cairo/libcairo ..

It's probably inline x86 asm, which the arm assembler wouldn't like too much

EDIT: you could try passing -D__NO_MATH_INLINES to avoid it
