libmultiprocess Installation

Installation currently requires Cap'n Proto:

apt install libcapnp-dev capnproto
brew install capnp cmake
dnf install capnproto

Installation steps are:

mkdir build
cd build
cmake ..
make
make check # Optionally build and run tests
make install

To build with libmultiprocess in a CMake project can specify:

find_package(Libmultiprocess)
target_capnp_sources(mytarget ${CMAKE_CURRENT_SOURCE_DIR} myschema.capnp)

Which will locate the libmultiprocess cmake package, and call the target_capnp_sources function to generate C++ files and link them into a library or executable target. See example/CMakeLists.txt for a complete example.

To build with libmultiprocess in a non-CMake project can use installed <prefix>/include/mpgen.mk Makefile rule to generate C++ files, and <prefix>/lib/pkgconfig/libmultiprocess.pc pkg-config definition to link against the runtime library.

For cross-compilation, it may be useful to build the runtime library and code generation binaries separately, which can be done with:

make install-bin # install bin/mpgen and related files
make install-lib # install lib/libmultiprocess.a and related files

It is also possible to import CMake targets separately with:

find_package(Libmultiprocess COMPONENTS Bin)
find_package(Libmultiprocess COMPONENTS Lib)
