mingw64 build failing

[nivpgir]

I'm trying to build Io on windows with mingw64, I'm not familiar with mingw but I managed to get it installed and in the path (I think), but when running mingw32-make I get the following error:

In file included from C:\Users\Niv\Downloads\io\libs\basekit\source\CHash.c:10:0:
c:\mingw\include\stdio.h:345:12: error: expected '=', ',', ';', 'asm' or '__attribute__' before '__mingw__snprintf'
 extern int __mingw_stdio_redirect__(snprintf)(char*, size_t, const char*, ...);
            ^
libs\basekit\CMakeFiles\basekit.dir\build.make:105: recipe for target 'libs/basekit/CMakeFiles/basekit.dir/source/CHash.c.obj' failed

I assumed it's a mingw64 issue and I found this SO question, and applied this patch linked from it, which got me through the error above, only to run into this error:

C:\Users\Niv\Downloads\io\libs\basekit\source\DynLib.c: In function 'dlopen':

libs\basekit\CMakeFiles\basekit.dir\build.make:165: recipe for target 'libs/basekit/CMakeFiles/basekit.dir/source/DynLib.c.obj' failed

which I can't find a solution to, so I've come here for help.

Maybe a specific version of mingw64 is required? or some other environment setting, I can see the CI builds succesfuly, so I don't know what's wrong with my setup.

It's probably worth noting that I also downloaded the build artifacts from the CI (by forking and running the CI action in my account, and taking the binary files from there), and that worked well, but then I ran in to the same compile error when installing eerie, when it tries to compile the Markdown addon, and since most of the addons don't ship binaries, it seems I need to solve it no matter what.

I appreciate any help solving this

That's a bit weird, ERROR_SUCCESS should come from windows.h. And if it can find the other windows stuff I can't see why that should be left out. I haven't built with mingw, but I can try it out.

I tested with the mingw toolchain from MSYS2 and it worked fine. What I did was (I already had cmake and gcc installed):

mkdir build && cd build
cmake -G "MinGW Makefiles" ..
cmake --build .

I really recommend using MSYS2 https://www.msys2.org for the toolchain, as it comes with a package manager and makes for a way more reproducible setup.

Thanks! compiling with msys succeeded, however, running io or io_static just freezes the terminal.
and when I try to run the eerie setup, the "Markdown" package compilation fails (different errors this time).
these are the errors in case you can help (I modified eerie to print all the commands to see what it's running):

however this might be a different issue that maybe I should take to Markdown.

[codecop]

For error: conflicting types for 'ssize_t' under MingW I had to set -D _NO_OLDNAMES during compilation (i.e. set the define _NO_OLDNAMES) which omits the branch with the duplicate definition. Not sure it helps here.
