They need to be compiled separately. Since some source files are +shared between these two parts, make sure to delete all object files between +compilations. Compile the Hexagon code first. + +The supported Snapdragon architectures are 855, 865, and 888. + +### Prerequisites + +1. Android NDK version r19c or later. +2. Hexagon SDK version 4.0.0 or later. + +Android NDK can be downloaded from https://developer.android.com/ndk. +Hexagon SDK is available at //developer.qualcomm.com/software/hexagon-dsp-sdk. + +### Compilation of the Hexagon part + +1. Build the static version of TVM runtime for Hexagon: this step is the same + as building the shared version, except at the cmake step, add + `-DBUILD_STATIC_RUNTIME=ON`. The compilation step should create + `libtvm_runtime.a`. + +2. Create a subdirectory for the build files, and run `cmake` with the + following variables set: + - `FASTRPC_LIBS=SKEL` + - `HEXAGON_SDK_ROOT` to the path to the Hexagon SDK + - `CMAKE_C_COMPILER=hexagon-clang` + - `CMAKE_CXX_COMPILER=hexagon-clang++` + - `HEXAGON_ARCH` to one of v65, v66, v68 + - `TVM_RUNTIME_HEXAGON=/path/to/libtvm_runtime.a` _statically_ linked + TVM runtime + Make sure to provide the path to launcher's `CMakeLists.txt` directory + in `cmake` invocation. + +3. Run `make`. This will create `liblauncher_rpc_skel.so`. + +### Compilation of the Android part + +1. Build TVM runtime for Android. Unlike in the Hexagon case, this should be + the dynamic library (which is the default), i.e. `libtvm_runtime.so`.
