Determine where the file libpython2.7.so is located ("find / -name
libpython2.7.so") and ensure that the path is in $LD_LIBRARY_PATH. You'll
need some other environmental variables set for the build as well, from the
last section in Gemenviron.profile (or Gemenviron):
this should get you there, or close:
export LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:/lib64:/usr/lib64:${OS_LIB}
export PYINC="-I/usr/include/python2.7"
export PYLIB="-L/usr/lib64 -lpython2.7"
export WITHPY="-DWITHPYTHON"
export PYDEP="-lpthread -ldl -lutil"
export
PYTHONPATH="/usr/lib64/python2.7/site-packages:/usr/lib/python2.7/site-packages:${NAWIPS}/scripts/python"
You have the option to not build against Python at all, simply remove the
last block from Gemenviron.profile (below) and source the file again (.
Gemenviron.profile) and run make.
