101 # in some cases when linking dynamic, the .a in /usr/lib is used
102 # instead of the .so in /lib due to gcc/libtool tweaking ld's

995 # archive. one way to determine this is by running the following commands:
996 # strings <pdv archive> | grep lseek
997 # strace -elseek <pdv archive>
998 # basically look for the first lseek command (we do the strings/grep because
999 # sometimes the function call is _llseek or something) and steal the 2nd
1000 # parameter. here is an example:
1001 # root@vapier 0 pdv_unpack # strings hldsupdatetool.bin | grep lseek
1002 # lseek
1003 # root@vapier 0 pdv_unpack # strace -elseek ./hldsupdatetool.bin
1004 # lseek(3, -4, SEEK_END) = 2981250
