Building from Source

Begin be fetching all needed source. :

git clone --recursive https://github.com/mdavidsaver/pvxs.git
git clone --branch 7.0 https://github.com/epics-base/epics-base.git

Prepare the PVXS source tree: :

cat <<EOF > pvxs/configure/RELEASE.local
EPICS_BASE=\$(TOP)/../epics-base
EOF

Build Base: :

make -C epics-base

Install or build libevent >=2.0

On RHEL7 and later. :

yum install libevent2-dev

On RHEL6 and earlier. :

yum install libevent-dev

On Debian/Ubuntu. :

apt-get install libevent2-dev

To build from source (Requires CMake): :

make -C pvxs/bundle libevent # implies .$(EPICS_HOST_ARCH)

For additional archs: eg. :

make -C pvxs/bundle libevent.linux-x86_64-debug

Build PVXS: :

make -C pvxs

It is recommended to run automatic unittests when building a new (to you) version of PVXS, or building on a new host. :

make -C pvxs runtests

Cross-compiling libevent2

The bundled libevent may be built for some cross compile targets. Currently only cross mingw. :

make -C pvxs/bundle libevent.windows-x64-mingw
