To build this library you will need GNU Make installed and any modern C compiler. Library is tested on Linux, *BSD and macOS operating systems. First you need to create features.mk makefile: cp src/platform/posix/features_tmpl.mk src/platform/posix/features.mk Edit it according to your needs. Defaults are fine. Note that with_frag, with_rbuf and with_msgq are experimental features and should not be used in production. To (re)build library, utilities and tests simply do: ./build.sh (MAKE=gmake ./build.sh on *BSD systems) In tests subdirectory you will find simple test examples. To test vc_server and vc_client (vconn feature) do: util/mknode n1 util/mknode n2 util/mknode n3 util/mknode server cd tests Then launch servers (each in its own terminal): ./vcs 0.0.0.0:3001 ../n1.priv ./vcs 0.0.0.0:3002 ../n2.priv 127.0.0.1:3001 ../n1.pub ./vcs 0.0.0.0:3003 ../n3.priv 127.0.0.1:3002 ../n2.pub ./vc_server ../server.priv 127.0.0.1:3001 ../n1.pub ../n2.pub ../n3.pub ./vc_client ../server.pub 127.0.0.1:3001 ../n1.pub ../n2.pub ../n3.pub
