46 # This function generate linker scripts in /usr/lib for dynamic
47 # libs in /lib. This is to fix linking problems when you have
48 # the .so in /lib, and the .a in /usr/lib. What happens is that
49 # in some cases when linking dynamic, the .a in /usr/lib is used
50 # instead of the .so in /lib due to gcc/libtool tweaking ld's
51 # library search path. This cause many builds to fail.
52 # See bug #4411 for more info.
53 #
54 # To use, simply call:
55 #
56 # gen_usr_ldscript libfoo.so
57 #
58 # Note that you should in general use the unversioned name of
59 # the library, as ldconfig should usually update it correctly
60 # to point to the latest version of the library present.

973 # strings <pdv archive> | grep lseek
974 # strace -elseek <pdv archive>
975 # basically look for the first lseek command (we do the strings/grep because
976 # sometimes the function call is _llseek or something) and steal the 2nd
977 # parameter. here is an example:
978 # root@vapier 0 pdv_unpack # strings hldsupdatetool.bin | grep lseek
979 # lseek
980 # root@vapier 0 pdv_unpack # strace -elseek ./hldsupdatetool.bin
