Package Detection

PSRCHIVE can be directed where to find third-party software packages using one or more of the following environment variables:
  • PKG_CONFIG_PATH : a colon-separated list of paths searched by pkg-config, which is used to find the compiler and linker flags for third-party dependencies including armadillo, cfitsio, fftw, healpix, and yaml-cpp.
  • PGPLOT_DIR : full path to the directory in which the PGPLOT libraries can be found
  • TEMPO2 : full path to the directory in which the TEMPO2 libraries can be found
  • PACKAGES : a space-separated list of absolute paths to base directories containing third-party packages that do not publish compilation information using pkg-config, including eigen, ipp, mkl, and splinter.

Using the PACKAGES environment variable

You can specify one or more root directories in which to search for packages using the PACKAGES environment variable. PSRCHIVE will search the sub-directories for the required pacakges. For example, suppose that you have
  • Splinter installed in /home/pulsar/packages
  • Intel Performance Primitives installed in /usr/local/intel/ipp/5.1/em64t
Simply 
setenv PACKAGES "/home/pulsar/packages /usr/local/intel"
before running the configure script.

Using configure script options

The above example could also have been handled with 
./configure --with-splinter-dir=/home/pulsar/packages \
  --with-ipp-dir=/usr/local/intel/ipp/5.1/em64t
For a complete list of --with options, type configure --help
