Used the instructions from https://www.rockbox.org/wiki/Windows10CrossCompiler and received the following error when compiling with the "make" command in WSL Ubuntu:
LD rockboxui.exe
/home/rob/rockbox/build-simulator/apps/action.o: file not recognized: file format not recognized
collect2: error: ld returned 1 exit status
make: *** [/home/rob/rockbox/uisimulator/uisimulator.make:34: /home/rob/rockbox/build-simulator/rockboxui.exe] Error 1
Also, the instructions need some updating simplification.
Installing SDL 1.2.15 "sudo make install" did not create the "cross-tools" folder in "usr/local/bin" due to a permissions issue. Had to create the folder manually.
Compiling instructions are... umm... vague.
From the Windows 10 Cross Compiler Wiki page:
Now you can compile the simulator:
enter your build directory and run somewhere/rockbox/configure
select platform, enter "A" (advanced), "S" (simulator) and "W" (Win32 cross-compile)
make it!
Should be (for us Windows devs that have been spoiled by Visual Studio and its built in compiler):
Enter or create a build folder in your rockbox directory (eg. rockbox/build-simulator)
Enter build directory and run "../tools/configure"
Select your platform ("22" for iPod Video)
Enter "A" for "(A)dvanced" option
Enter "S" for "(S)imulator", then press enter
Enter"W" for "(W)in32 cross-compile", then press enter twice
After build is configured, run "make".

Ok, ran "../tools/configure" again and have a different error.

I always see people having issues due to dependencies missing maybe try these from the more recent beginners guide?
sudo apt-get install automake bison build-essential ccache flex libc6-dev libgmp3-dev libmpfr-dev libsdl1.2-dev libtool-bin texinfo zip gawk

I solved it about an hour ago by running "make clean".
Just needed to get some sleep. Woke up this morning and realized I'd seen a similar issue when compiling a media player I wrote a few years ago that I wrote in C++ using VS2015, but wrote for multiple platforms. I remembered spending hours going through options, searching the web, and rebuilding repeatedly. Then, I realized I had turned off the option to clean before build. I turned it back on and my code compiled just fine.
I looked up how to clean the configuration output using make (yes, there was a facepalm involved), ran the clean command, and I now have a working UI Simulator.
Thank you for your assistance.
P.S. May want to add that to the build wiki
