- Build TVM library with Hexagon support for host machine.
- Build TVMRuntime library and C++ RPC server for host machine.
-To build these pieces, you can use a cmake command as follow.
+Note: before moving forward make sure to export Clang libraries to
`LD_LIBRARY_PATH` and Hexagon toolchain to `HEXAGON_TOOLCHAIN`.
+
+To build these pieces, first build Hexagon API application under
`apps/hexagon_api`.
```bash
-cmake -DUSE_HEXAGON_RPC=ON \
-
-DUSE_ANDROID_TOOLCHAIN=/path/to/android-ndk/build/cmake/android.toolchain.cmake
\
+cd apps/hexagon_api
+mkdir build
+cd build
+cmake
-DUSE_ANDROID_TOOLCHAIN=/path/to/android-ndk/build/cmake/android.toolchain.cmake
\
-DANDROID_PLATFORM=android-28 \
-DANDROID_ABI=arm64-v8a \
-DUSE_HEXAGON_ARCH=v65|v66|v68 \
-DUSE_HEXAGON_SDK=/path/to/Hexagon/SDK \
- -DUSE_HEXAGON_TOOLCHAIN=/path/to/Hexagon/toolchain/ \

-DUSE_HEXAGON_TOOLCHAIN=/path/to/Hexagon/toolchain/"Tools"/sub-directory \
+ -DUSE_OUTPUT_BINARY_DIR=/path/to/"tvm/build/hexagon_api_output" ..
+```
+
+This command generates `tvm_rpc_android` and `libtvm_runtime.so` to run on
Android. Also, it generates `libtvm_runtime.a` and `libhexagon_rpc_skel.so` to
run on Hexagon device. Now we have TVM artifacts which are used to run on the
remote device.
+
+Next, we need to build TVM on host with RPC and Hexagon dependencies. To do
that follow these commands.
+
+```bash
+cd tvm
+mkdir build
+cd build
+cmake -DUSE_LLVM=/path/to/llvm/bin/llvm-config \
