prepare.sh and build.py errors on clean install (WSL)

[ronchonbon]

Recently did a clean Ubuntu install with WSL and have ran into a few issues trying to build Ren'Py. The first two have simple fixes, the third I can't figure out.

./prepare.sh gives multiple instances of the error

/usr/bin/ld: cannot find -lassimp: No such file or directory collect2: error: ld returned 1 exit status

which is solved by

sudo apt-get install libassimp-dev

./build.py --platform mac (eventually) gives the error

FileNotFoundError: [Errno 2] No such file or directory: 'llvm-lipo-15'

which I got around with

sudo apt-get install clang-15

but there's probably a better solution?

./build.py --platform linux --arch aarch64 gives the following error in install_linux():

W: Failure trying to run: chroot "/home/rb/renpy-build/tmp/sysroot.linux-aarch64" /bin/true

and debootstrap.log says

chroot: failed to run command '/bin/true': Exec format error

Haven't figured out a solution for this one yet.

Hope this helps!
