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.

144 # try with -p0 to -p5 until it succeed, or fail at -p5.

146 # Above EPATCH_* variables can be used to control various defaults,
147 # bug they should be left as is to ensure an ebuild can rely on
148 # them for.

151 #
152 # Bulk Patches should preferibly have the form of:

156 # For example:
157 #
158 # 01_all_misc-fix.patch.bz2
159 # 02_sparc_another-fix.patch.bz2

161 # This ensures that there are a set order, and you can have ARCH
162 # specific patches.

165 # single patch that need to be applied if its a file. If on the other
166 # hand its a directory, it will set EPATCH_SOURCE to this.

970 # basically look for the first lseek command (we do the strings/grep because
971 # sometimes the function call is _llseek or something) and steal the 2nd
972 # parameter. here is an example:
973 # root@vapier 0 pdv_unpack # strings hldsupdatetool.bin | grep lseek
974 # lseek
975 # root@vapier 0 pdv_unpack # strace -elseek ./hldsupdatetool.bin
