gpt_build_config - Returns a minimized list of ldflags from a list of
globus packages and external libraries.
gpt_build_config -src <source metadata file> -f <globus_flavor_name>
gpt_build_config creates a file in it’s current directory named
gpt_build_temp.sh that contains a list of necessary flags assembled
from the build environment metadata of the packages on which the source
metadata depends. This scanning is done recursively to cover the
entire dependency tree. This script was initially inspired by the
shell script gnome_config.
The flag list returned by gpt_build_config is assembled in dependent
order. A dependency between two libraries occurs when one library
needs the symbols of another library in order to link correctly. For
most linkers the library providing the symbols has to be linked after
the library that needs the symbols. For example, from the line:
-L/opt/Xpm/lib -lXpm -L/usr/lib/X11 -lXm -lX
gpt_build_config assumes that the library Xpm is dependent on Xm which
in turn is dependent on X. In addition, gpt_build_config assumes that
Xpm is located in /opt/Xpm/lib and Xm and X are both located in
Circular dependencies between libraries are not supported.
