# This shell script provides a wrapper for ld under AIX in order to
|
|
# create the .exp file required for linking. Its arguments consist
|
|
# of the name and arguments that would normally be provided to the
|
|
# ld command. This script extracts the names of the object files
|
|
# from the argument list, creates a .exp file describing all of the
|
|
# symbols exported by those files, and then invokes "ldCmd" to
|
|
# perform the real link.
|
|
|
|
# Extract from the arguments the names of all of the object files.

# Create the export file from all of the object files, using nm followed

|
|
#
|
|
# - Use the -X32_64 switch to nm to handle 32 or 64bit compiles.
|
|
# - Eliminate lines that end in ":": these are the names of object files
|
|
# - Eliminate entries with the "U" key letter; these are undefined symbols
|
|
# - If a line starts with ".", delete the leading ".", since this will just
|
|
# cause confusion later
|
|
# - Eliminate everything after the first field in a line, so that we're
|
|
# left with just the symbol name
