Setting up the Win32 cross compiler from WSL

[saratoga]

I've done this before but cannot seem to get it to work now.  I've followed the instructions here:

https://www.rockbox.org/wiki/Windows10CrossCompiler#Build_Simulator

I configure a win32 simulator build and disable codecs (since mikmod won't build on win32 due to typedef conflicts).  The build process fails:

I'm running mingw-w64 5.0.3-1 (per apt-get).

What is the output of "file /home/mike/rockbox/winsim/apps/bitmaps/mono/default_icons.o"?

mike@Home-PC:~/rockbox/winsim$ file /home/mike/rockbox/winsim/apps/bitmaps/mono/default_icons.o
/home/mike/rockbox/winsim/apps/bitmaps/mono/default_icons.o: ELF 32-bit LSB relocatable, ARM, EABI5 version 1 (SYSV), not stripped

So something is wrong there.

To follow up on our brief exchange on IRC, I can compile the current version on my Ubuntu on Windows Subsystem for Unix following the guide at https://www.rockbox.org/wiki/Windows10CrossCompiler.

I was wrong that I compiled mine last in winter, it was actually in june 2021.

The only thing I did to make it compile was edit apps/plugins/SUBDIRS to remove midi/mikmod/lua/lua_scripts. It is quite possible some of these can be made to compile, but I did not need them.

My Ubuntu is a bit old now though, it is 20.04 (outdated too, last updated june 2021). mingw-w64 claims to be 7.0.0-2, with i686-w64-mingw32-gcc 9.3-win32.

With those 4 plugins removed, it compiles quickly and without errors.
