System.NullReferenceException in MexTK.Commands.CmdFighterFunction.CompileInput

[CaioIcy]

In my Windows 10 machine, running the build.bat for any of the patch/events/... yields the following:

H:\...\Training-Mode\patch\events\ledgedash>xcopy /s /y "assets\ldshData.dat" "output/EvLdsh.dat"
assets\ldshData.dat
1 File(s) copied                                                                                                                                                                                

H:\...\Training-Mode\patch\events\ledgedash>"../../../MexTK/MexTK.exe" -ff -i "source/ledgedash.c" -s evFunction -dat "output/EvLdsh.dat" -t "../../../MexTK/evFunction.txt" -q -ow -w -c -l "../../../MexTK/melee.link" -op 1

Unhandled Exception: System.NullReferenceException: Object reference not set to an instance of an object.

Press any key to continue . . .

It outputs a new EvLdsh.dat, but when I imported it over the official v3.0 Alpha 3 through GCRebuilder the event crashes on load.

I am having the same issue currently. Did you find a solution or did you give up on it?

[DewanckelJonas]

I got the solution from UnclePunch. You need to install Devkitppc to be able to compile the c code.

Installing devkitPro was the solution, thank you @DewanckelJonas ! For others that see this, you can get it here: https://devkitpro.org/wiki/Getting_Started
