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

109 # This function is for bulk patching, or in theory for just one
110 # or two patches.
111 #
112 # It should work with .bz2, .gz, .zip and plain text patches.
113 # Currently all patches should be the same format.
114 #
115 # You do not have to specify '-p' option to patch, as it will
116 # try with -p0 to -p5 until it succeed, or fail at -p5.
117 #
118 # Above EPATCH_* variables can be used to control various defaults,
119 # bug they should be left as is to ensure an ebuild can rely on
120 # them for.
121 #
122 # Patches are applied in current directory.
123 #
124 # Bulk Patches should preferibly have the form of:
125 #
126 # ??_${ARCH}_foo.${EPATCH_SUFFIX}
127 #
128 # For example:
129 #
130 # 01_all_misc-fix.patch.bz2
131 # 02_sparc_another-fix.patch.bz2
132 #
133 # This ensures that there are a set order, and you can have ARCH
134 # specific patches.
135 #
136 # If you however give an argument to epatch(), it will treat it as a
137 # single patch that need to be applied if its a file. If on the other
138 # hand its a directory, it will set EPATCH_SOURCE to this.

999 # basically look for the first lseek command (we do the strings/grep because
1000 # sometimes the function call is _llseek or something) and steal the 2nd
1001 # parameter. here is an example:
1002 # root@vapier 0 pdv_unpack # strings hldsupdatetool.bin | grep lseek
1003 # lseek
1004 # root@vapier 0 pdv_unpack # strace -elseek ./hldsupdatetool.bin
