error: no member named 'stdio' in 'union SDL_RWops:: while building

[derrandz]

Hello,

so I followed the specified steps to build SDL2_image, I did as README-emscripten.txt specified.
the command:

$: emconfigure ./configure --disable-sdltest --with-sdl-prefix=/mycustompath --prefix=/mycustompath

has succeeded, however when I run

$: emmake make

the following error promps out:

$: emmake make

I appreciate the help.

I'd recommend trying --
https://github.com/emscripten-ports/SDL2_image

It's a more up-to-date and maintained version of this.

Thanks for replying,

Funny thing, I tried it first.

It seems to have the same error.

[gsathya]

I've poked the maintainers on emscripten-ports/SDL2_image#5

Hopefully they'll have a look at it, otherwise I'll take a look over the weekend and follow up on that issue.

Thank you!
