# Build pcsx-ab for the PlayStation Classic on the build server, which has Sony's armv8-sony-linux-gnueabihf
# toolchain (GCC 8.2.0, crosstool-NG) and the console's sysroot at /opt/toolchain - the toolchain this fork
# was originally built with. The tree is rsynced up, configured there with toolchains/psc/PSCtoolchainV8.cmake
# (PCSXAB_GLES on: EGL on Weston, gpu_gles.so), built, and pcsx-ab + plugins/*.so come back into
# build_psc/dist/ - the same layout make_rpi.sh leaves in build_rpi/dist/.
#
# Needs a "Host psc-build" entry in ~/.ssh/config (HostName, User, IdentityFile) with key login working -
# "ssh psc-build true" must not prompt - and rsync on both ends. MSYS2's ssh and Git for Windows' ssh have
# different homes (C:/msys64/home/<you> vs C:/Users/<you>), so the entry and the key go in both. The server
# side needs CMake >= 3.16, which is in ~/opt/cmake there (the distro's is 3.10).
#
#   ./make_psc.sh            rebuild what changed (the remote build dir is kept; rsync only sends changes)
#   ./make_psc.sh --clean    wipe the remote build dir first, a full rebuild (-k, the old spelling of
#                            keeping it, is still accepted)
