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. # # RCS: @(#) $Id: ldAix,v 1.4.18.1 2010/08/12 00:11:23 hobbs Exp $ # Extract from the arguments the names of all of the object files. args=$* ofiles="" for i do x=`echo $i | grep '[^.].o$'` if test "$x" != ""; then ofiles="$ofiles $i" fi done # Extract the name of the object file that we're linking. outputFile=`echo $args | sed -e 's/.*-o \([^ ]*\).*/\1/'` # Create the export file from all of the object files, using nm followed # by sed editing.
