Building a module for (P)elegant

Home page and official build instructions

Elgant is a software packages produced by the Accelerator Operations and Physics Group. It requires the EPICS build-system and SDDS. The EPICS build-system is completely based on Makefiles. This makes it a bit harder to compile and more error prone.

Instructions to setup epics/base, epics/extensions and to compile SDDS as well as elegant can be found here. The instructions to build from source are almost at the end of the page.

make -e "${ARGS[@]}"

Unpack EPICS extensions and OAG apps configuration

#ARGS+=( "TOOLS=${PREFIX}/bin")
cd "${PREFIX}"
tar xvf "${DOWNLOAD_DIR}/epics.extensions.configure.tar.gz"
tar xvf "${DOWNLOAD_DIR}/oag.apps.configure.tar.gz"
cd "${PREFIX}/oag/apps/configure"
sed -i "s/clean::/clean:/" RULES_PYTHON
make -e "${ARGS[@]}"

Build required tools and libraries from SDDS


cd "${PREFIX}"
tar xvf "${DOWNLOAD_DIR}/SDDS.${SDDS_VERSION}.tar.gz"
cd "${PREFIX}/epics/extensions/src/SDDS/"
sed -i -e  "s/\( sddspseudoinverse_SYS_LIB.*\)/\1 gfortran/" SDDSaps/pseudoInverse/Makefile
