I'm getting IL2CPP build error for some reason

Question

For some reason, I'm getting build errors. I was be able to build my project clearly with mono. I'm trying to build the project with IL2CPP now and getting some errors.

I tried:

• Changing Windows language to English. In fact, I reinstalled Windows 11.
• And reinstall Unity, Visual Studio and sdk, ndk etc.

Btw, the error is about file path of compile.rsp file. I manually checked that file path and the file. it is exist in the right file location.

Here is the errors and console messages.

Error 1:

Answer 1

I finally solved my problem.

2 things you must be sure

1. Set your Windows Display Language to English
2. Change your Unity version from 2021.2 to 2020.3

These 2 thing most probably solve your problem like mine

Answer 2

Hocam IL2CPP ile build almaya çalıştığım zaman tıpa tıp aynı hatayı veriyor, benim Unity versiyonum 2021.2.7f1 hangi versiyona düşürmeliyim veya düşürmeden çözmenin bir yolu var mıdır? İyi çalışmalar.

Answer 3

In case the answer presented doesn't help, I've found a different possible cause of the error - large arrays of values (over 10k elements) can't be handled by IL2CPP specifically. No clue why-how, it just was mentioned on a thread in Unity forum, and it did solve the problem for me - I just dropped all the values in the text file and parsed it on startup.
