This document walks you through building Touca SDK for C++ and its side components from its source code. Refer to our Installing Instructions to learn how to pull Touca as a third-party dependency.


You can build Touca on Linux, macOS, and Windows platforms. We support C++11 and newer standards. We use CMake as our build system. You would need CMake v3.14 or newer to build Touca. We formally support the following compilers:

CompilerMin Version
x86-64 gcc7.1
x86-64 clang7.0.0
x64 MSVC1900

Obtaining the Source Code

Touca SDK for C++ is available on GitHub under the Apache-2.0 license. Clone this repository to a directory of your choice. We refer to this directory as <project_directory>.

git clone
cd sdk/cpp

Using Our Helper Script

Touca SDK for C++ has five main components.

NameBuild Argument
Core Library
Test Framework--with-framework
Sample Regression Test Tools--with-examples
Utility Command Line Tool--with-cli
Unit Tests--with-tests

We provide build scripts and build.bat for Unix and Windows platforms, respectively. The build scripts build the core library and the test framework by default. You can pass the appropriate argument shown in the table above to build other components as needed.

As an example, the command below builds all the components except the unit tests.

./ --with-cli --with-examples

You can build all of the components using the --all argument.

./ --all

Using CMake Directly

If, for any reason, you do not want to build Touca using our helper scripts, you can always use CMake directly. To do so, we recommend running the following command first, to configure the build targets and specify the path in which build artifacts should be generated. While you can change the build directory to the directory of your choice, the subsequent instructions assume the default value of ./local/build.

cmake -B"<project_directory>/local/build" -H"<project_directory>"

By default, the above-mentioned command configures CMake to build the core Touca Client Library. But Touca has several other components that can be enabled by passing the appropriate options to the command above, as listed in the table below.

Component NameCMake OptionDefault
Command-Line ApplicationTOUCA_BUILD_CLIOFF

As an example, the command below enables building sample Touca tests.

cmake -B"<project_directory>/local/build" -H"<project_directory>" -DTOUCA_BUILD_EXAMPLES=ON

We can build the source code via CMake which uses the native build tool of your platform.

cmake --build "<project_directory>/local/build" --parallel

Optionally, as a last step, we can install the build artifacts in a directory of our choice for easier packaging.

cmake --install "<project_directory>/local/build" --prefix "<project_directory>/local/dist"
