Install

Meson (recommended)

git clone --recurse-submodules https://github.com/HaoZeke/c-capnproto.git
cd c-capnproto
meson setup build
meson compile -C build
# plugin: build/capnpc-c   runtime: build/libcapnp.a (or shared)
meson install -C build   # optional: put capnpc-c on PATH

CMake (optional)

Meson is the default. CMake is an install-path alternative (MSVC / IDE / packagers). It does not use the DKML dk wrapper and does not fetch or delete the gtest/ submodule.

cmake -S . -B build-cmake
cmake --build build-cmake
cmake --install build-cmake
ctest --test-dir build-cmake  # only if CMake found an installed GTest

Tests are skipped when GTest is not installed. Use Meson (or autotools with the existing gtest/ submodule) for the full suite.

Autotools

git clone --recurse-submodules https://github.com/HaoZeke/c-capnproto.git
cd c-capnproto
autoreconf -f -i -s
./configure
make
make check

Kernel module

The runtime can be compiled into a kernel module (__KERNEL__). This is not the default and is not covered by CI. See KERNEL.md and examples/kernel.
