# library search path. This cause many builds to fail.
# See bug #4411 for more info.
#
# To use, simply call:
#
# gen_usr_ldscript libfoo.so
#
# Note that you should in general use the unversioned name of
# the library, as ldconfig should usually update it correctly

# information out of the binary executable myself. basically you pass in
# the size of the off_t type (in bytes) on the machine that built the pdv
# archive. one way to determine this is by running the following commands:
# strings <pdv archive> | grep lseek
# strace -elseek <pdv archive>
# basically look for the first lseek command (we do the strings/grep because
# sometimes the function call is _llseek or something) and steal the 2nd
# parameter. here is an example:
# root@vapier 0 pdv_unpack # strings hldsupdatetool.bin | grep lseek
# lseek
# root@vapier 0 pdv_unpack # strace -elseek ./hldsupdatetool.bin
# lseek(3, -4, SEEK_END) = 2981250
