Cannot compile native Skia, python3 does not exist. about skiasharp HOT 6 CLOSED

I got a little further, apparently I had to set the environment variable (PYTHON_EXE) for the python exe instead of just the path variable. I updated dependencies again, and after that I was missing choco and ninja.

I am wondering if the install docs need updated? They are the same as when we first built our own libraries and they are MUCH different now. But good news is, I am compiling now, so I guess this can be closed.

Compiling after setting the PYTHON_EXE environment variable to the actual exe instead of only the path.

I jumped the gun, externals-windows works but android does not. I can get it to compile by copying the python executable to python3.exe but I am sure thats the wrong route. The script is running cmd.exe which doesnt have the variable is my suspicion. python3 error again:

Do you have python3 installed into the PATH variable?

Yea sorry its been awhile since I looked at this but we are fully compiling now. The issue I think that needs resolved is an update to the docs as they appear really outdated. We saved a list in a "How To" so we can just keep coming back to that as its hard to remember the entire list when you only re compile every so often on updates. We have a full list of packages and programs to install and then a build list of environment variables to set as well as what not to install (Tizen) and what to skip (Tizen). Tizen has some install issues right now in VS and windows that basically kills any other development on mobile including android. They are aware of the issue but arent willing to fix it (we used to restore backups on a build machine after builds where Tizen wasnt installed). We dont target Tizen anyways, and really just need the info in the build list.

So again, I think its just the build docs need updated with everything needed like LLVM, choco, Python, Ninja, Tizen, Node.js, on and on... As well as all the environment settings to build each time, for us for some reason we have to tell it where everything is like 'PYTHON_EXE', 'LLVM_HOME', 'ANDROID_NDK_HOME', as well as adding nodejs and Python312 paths.
