# This script is needed in the process of generating exported
|
|
# symbols list out of map files on Mac OS X (see also #i69351#)
|
|
# The magic generating the regular expression from the temporary
|
|
# mapfile containing only star and question mark symbols
|
|
#
|
|
# The script has to be called as follows:
|
|
# nm -gx <file>.o | addsym-macosx.sh <file-with-wildcard-symbols> <temporary-file-where-to-write-the-search-expression-to>
|
|
# See tg_shl.mk for an example of how to use the script
|
|
#
|
|
# Replace every * with .* and every ? with . to get awk expression
|
|
# Put ^ at the beginning of every expression
|
|
# Put $ at the beginning of every expression
|
|
# Connect them all on one line, separated by |
|
|
# Remove | at the end of this regular expression because the last end
|
|
# of line was also replaced by |
|
|
|
|
cat $1 | sed 's#*#.*#g
|
|
s#?#.#g
|
|
s#^#^#
|
|
s#$#$#' | tr '\n' '|' | sed "s#|\$##" >$2
|
|
|
|
# Please note that the awk expression expects to get the output of 'nm -gx'!
|
|
# On Panther we have to filter out symbols with a value "1f" otherwise external
|
|
# symbols will erroneously be added to the generated export symbols list file.
