How to build Turnip for SurfaceFlinger on-device without a PC and without zhiyong/termux-ndk

README.md

How to build Mesa Turnip with -Dplatforms=android but without cross-compilation

Small warning: This will "mess up" your Termux installation's zlib.pc file, but if you do other compilations with really similar settings to this one, you're probably going to need it again before you "fix" it by reinstalling Termux's official zlib anyway.

1. Install Termux

termux-setup-storage
pkg install git make clang binutils
git clone https://github.com/madler/zlib.git
cd zlib/
git checkout 643e17b
./configure --static
make install prefix=$PREFIX

mkdir -p $PREFIX/lib/static
mv $PREFIX/lib/libz.a $PREFIX/lib/static/
cd
git clone https://github.com/termux/termux-packages.git
cd termux-packages/

./scripts/setup-termux.sh
pkg install bison
pip install mako
# If this fails with anything like "E: Version '2.4.118' for 'libdrm' was not found... building instead" it means your current Termux mirror is outdated or the git commit of termux-packages repo is too old. Use termux-change-mirror to select different ones and rebase the patches on upstream termux-packages until the error disappears
./build-package.sh -I -f mesa

pkg install p7zip ldd patchelf
# Inspect the linkage of the binary for problems. Any instance of "com.termux" in this list probably means you used the wrong dependencies and need to adjust them, except that when I build on one of my devices for some reason it shows "com.termux/files/usr/lib/libc++_shared.so" here when builds on other devices don't, but when I proceed and test it anyway it seems to still work. I don't know why.
