You can build onnc source with either CMake or Automake building system.

Building with CMake

There are 2 modes, Release mode and debug mode, provided in CMake building system.

Release mode

Recommended for common use.

Release mode will build onnc with basic optimizations, and skip debug informations.

Notice: Release mode will NOT build unit tests.

Step 1: Configure

$ mkdir -p build && cd build
$ cmake -DCMAKE_BUILD_TYPE=Release ..

It will create build directory, get into it and configure with Release build type.

Step 2: Build

$ make -j4

It will compile sources with 4 threads concurrently. You can modify -j4 option to meet your needs.

Step 3: Install

$ sudo make install

It will install essential files to /usr/local.

Debug mode

Recommended for development use.

Debug mode will build onnc with debug settings, unit tests and some debug informations.

Step 1: Configure

$ mkdir -p build && cd build
$ cmake -DCMAKE_BUILD_TYPE=Debug ..

It will create build directory, get into it and configure with Debug build type.

Step 2: Build

$ make -j4

It will compile sources with 4 threads concurrently. You can modify -j4 option to meet your needs.

Step 3: Test

$ ctest

It will trigger all unit tests by CTest.

If you want to execute single unit test, you can find it in build/tools/unittests directory.

Step 4: Install

$ sudo make install

It will install essential files to /usr/local.

Advanced configurations

You can override default configurations by simply add -DENTRY=VALUE options to the configure command. The ENTRY and VALUE can be replaced according to the following table:

"Path string" of value means you have to provide a string of a directory path, and "File path string" means you have to provide a string of a file path.

Entry	Available values	Default	Description
CMAKE_INSTALL_PREFIX	Path string	/usr/local	Path to install onnc into
CMAKE_BUILD_TYPE	Debug,Release	Release	Build mode

MKLDNN_ROOT	File path string	System default path	Path of MKLDNN libraries

Use cmake -L .. inside build directory to get more detailed options.
