13.4. BUILDING mesytec-mvlc WITH THE OPTIONAL fribdaq-readout PROGRAM

If you are using a version of FRIB/NSCLDAQ 12.1 or higher, or at the FRIB in the containerized environment, The /usr/opt/ filesystem for the bookworm container will include at least one version of the mesytec mvlc support software that includes fribdaq-readout, and you can ignore the remainder of this section.

If you are using a native version of FRIB/NSCLDAQ 11.0 and higher, we encourage you to use a containerized environment so that you can ignore this section.

If you are stubborn, then this section describes how to build the Mesytect-mvlc software so that it includes the fribdaq-readout program and the appropriate headers to allow you to build timestamp extractors.

Until our contribution of fribdaq-readout is merged into a release, you'll need to do the following:

1. Clone the https://github.com/flueke/mesytec-mvlc repository.

2. Checkout the fribdaq-readout branch. This is necessary as long as the main branch does not include the extras/frbdaq directory.

3. Create a direcory in which you will do the build.

4. Use cmake to generate the Makefiles in the build directory. You will want to specify -DCMAKE_INSTALL_PREFIX=installation-root and -DNSCLDAQ_ROOT=install-root-of-nscldaq Where installation-root is where you want the software installed, and install-root-of-nscldaq is the installation directory for the verison of FRIB/NSCLDAQ you want to build against. 12.0 or higher is recommended though it might work with 11.x as well.

5. make to build the software. If you have a multicore system, you can speed this up using the -j to specify a parallel make.

6. Optionally run the unit tests: make test.

7. make install to install the software where you specified in -DCMAKE_INSTALL_PREFIX

If your working directory is a clone of the repository with the appropriate branch checked out, here's an example of how to do all of this.

mkdir build
cd build
cmake .. -DCMAKE_INSTALL_PREFIX=/usr/opt/mesytec-mlc/0.1.0 -DNSCLDAQ_ROOT=/usr/opt/daq/12.1-007
(bunch of output here)
make -j12                     # Make for 12 cores.
(more output here)
make test                     #optional 
(more output here)
make install
(final bits of output here)
