Introduction
Use of CMake to build Offline in the DAQ environment.
Building Offline with CMake
Using UPS
The UPS-based build of Offline is supported in SL7 environments, in two distinct flavors:
Package-based build
The Offline CMake uses the cetmodules package for several CMake convenience functions, and can be built using the standard cetmodules invocation:
source /cvmfs/mu2e.opensciencegrid.org/setupmu2e-art.sh git clone https://github.com/Mu2e/Offline.git mkdir build_Offline && cd build_Offline source ../Offline/ups/setup_for_development -p e28:s126:trig # -d or -p are supported, see Offline/ups/product_deps for supported qualifier combinations export CETPKG_J=$((`cat /proc/cpuinfo|grep processor|tail -1|awk '{print $3}'` + 1)) # Set build parallelism to number of CPUs on host buildtool # -p to create a UPS-redistributable package, -i to install in a UPS area (-I to specify which)
MRB-based build
Offline is also compatible with MRB-based development:
source /cvmfs/mu2e.opensciencegrid.org/setupmu2e-art.sh setup mrb mkdir my_mrb_working_area export CETPKG_J=$((`cat /proc/cpuinfo|grep processor|tail -1|awk '{print $3}'` + 1)) # Set build parallelism to number of CPUs on host export MRB_PROJECT=Mu2e mrb newDev -v v1_00_00 -q e28:s126:trig:prof # Version here is mostly meaningless, but required to silence certain CMake warnings cd srcs mrb gitCheckout https://github.com/Mu2e/Offline.git mrb uc mrb z mrbsetenv mrb b
Using Spack
When to Update CMakeLists.txt
In general, CMakeLists.txt in affected packages should be updated when:
- Files are added, removed, or renamed
- Library dependencies for a package change (e.g. a #include referring to another package is added or removed)
- Data files are added to a package and should be installed when Offline is built
