21 # Usage:
22 #
23 # ecpu_check array_of_cpu_flags
24 #
25 # array_of_cpu_flags - An array of cpu flags to check against USE flags
26 #
27 # Checks user USE related cpu flags against /proc/cpuinfo. If user enables a
28 # cpu flag that is not supported in their processor flags, it will warn the
29 # user if CROSSCOMPILE is not set to 1 ( because cross compile users are
30 # obviously using different cpu flags than their own cpu ). Examples:
31 #
32 # CPU_FLAGS=(mmx mmx2 sse sse2)
33 # ecpu_check CPU_FLAGS

91 # This function generate linker scripts in /usr/lib for dynamic
92 # libs in /lib. This is to fix linking problems when you have
93 # the .so in /lib, and the .a in /usr/lib. What happens is that
94 # in some cases when linking dynamic, the .a in /usr/lib is used
95 # instead of the .so in /lib due to gcc/libtool tweaking ld's
96 # library search path. This cause many builds to fail.
97 # See bug #4411 for more info.
98 #
99 # To use, simply call:
100 #
101 # gen_usr_ldscript libfoo.so
102 #
103 # Note that you should in general use the unversioned name of
104 # the library, as ldconfig should usually update it correctly
105 # to point to the latest version of the library present.

1153 # archive. one way to determine this is by running the following commands:
1154 # strings <pdv archive> | grep lseek
1155 # strace -elseek <pdv archive>
1156 # basically look for the first lseek command (we do the strings/grep because
1157 # sometimes the function call is _llseek or something) and steal the 2nd
1158 # parameter. here is an example:
1159 # root@vapier 0 pdv_unpack # strings hldsupdatetool.bin | grep lseek
1160 # lseek
1161 # root@vapier 0 pdv_unpack # strace -elseek ./hldsupdatetool.bin
1162 # lseek(3, -4, SEEK_END) = 2981250
