Compiler errors when building on win32/mingw

[jakubzitny]

Hi there,

I am trying to (statically) build mozjpeg for/on 32bit Windows under cygwin/mingw, however, the following errors occur:

jmorecfg.h:209:33: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘static’
 #define LOCAL(type)             static type
                                 ^
jccolext.c:31:1: note: in expansion of macro ‘LOCAL’
 LOCAL(void)
 ^

Full output of make is here.

I tried ./configure with --enable-static --disable-shared as it was suggested in #245 and also without it. I followed similar steps on othere platforms and I am not getting the errors there.

Any ideas on what I am doing wrong or how can I further debug this?

Thanks.

It looks like ./configure generates invalid configuration and/or your compiler is weird and broken.

Officially libjpeg-turbo (on which MozJPEG is based) only supports CMake on Windows, so probably this is unsupported, even in mingw environment.

So forget about configure && make, and try cmake instead.
