Requires QNX SDP to build, with QNX_TARGET and QNX_HOST environment variables set. Make sure the latest meson is installed.
Build scripts are made available to show how to cross-compile gfxstream and its aemu dependencies. See ./qnx/nto/build-aemu.sh and ./qnx/nto/build-gfxstream.sh
cd ./qnx make
Make will navigate to ./qnx/nto/aarch64le and run the build scripts from there.
The aemu dependency is downloaded to, and built in ./qnx/nto/aarch64le/aemu.
Gfxstream's build directory is ./qnx/nto/aarch64le/gfxstream.
cd ./qnx make install
The install target requires the INSTALL_ROOT_nto environment variable, which sets the qnx staging/install path.
pinfo.mk writes build info into the binary:
# use -i ./nto/aarch64le/gfxstream/host/libgfxstream_backend.so QNX_BUILDID=(GNU)5dc1327b962ed2a7e992c1f6f35c0df3 NAME=libgfxstream_backend.so DESCRIPTION=virtio-gpu backend renderer DATE=2023/09/18-10:58:49-EDT COMMIT=7b8c19e51845aee014684c43e6aa8409e919af6a
A “recursive make” directory layout is used to allow multiplatform builds. For more info, see: Conventions for Recursive Makefiles and Directories
