Chapter 7: Building and Packaging

Prerequisites

Install the following software:

• CMake 3.15
• Conan 1.34.1
• GCC 10

Assuming you're on Linux or using WSL, configure a hosacpp Conan profile and remotes by running:

conan profile new hosacpp || true
conan profile update settings.compiler=gcc hosacpp
conan profile update settings.compiler.libcxx=libstdc++11 hosacpp
conan profile update settings.compiler.version=10 hosacpp
conan profile update settings.arch=x86_64 hosacpp
conan profile update settings.os=Linux hosacpp

If GCC 10 is not your default compiler, you also need to add:

conan profile update env.CXX=`which g++-10` hosacpp
conan profile update env.CC=`which gcc-10` hosacpp

Building

To build the customer project, first cd to its source directory, and then run:

mkdir build
cd build
conan install .. --build=missing -s build_type=Release -pr=hosacpp
cmake .. -DCMAKE_BUILD_TYPE=Release # build type must match Conan's
cmake --build .

If GCC 10 is not your default compiler, you can tell CMake to use it with the CMAKE_CXX_COMPILER flag. Replace the first invocation above with:

cmake .. -DCMAKE_BUILD_TYPE=Release -DCMAKE_CXX_COMPILER=`which g++-10`

Testing

To run tests from each of the projects, cd into their respective build directory, and then simply run ctest.

Installing

In the build directory, run cmake --install . to install the software into ${CMAKE_PREFIX_PATH}. If no prefix is given, it will install system-wide. To change this, add -DCMAKE_INSTALL_PREFIX=/path/to/install/to to your cmake invocation.

Packaging

In the build directory, run cpack. Simple as that. Assuming you're running on a system supporting DEB packages, you'll get a .tar.gz file, a .zip file, and a .deb package.

Building a Conan package

In the build directory, run cmake --build . --target conan.
