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

103 # This function is for bulk patching, or in theory for just one
104 # or two patches.
105 #
106 # It should work with .bz2, .gz, .zip and plain text patches.
107 # Currently all patches should be the same format.
108 #
109 # You do not have to specify '-p' option to patch, as it will
110 # try with -p0 to -p5 until it succeed, or fail at -p5.
111 #
112 # Above EPATCH_* variables can be used to control various defaults,
113 # bug they should be left as is to ensure an ebuild can rely on
114 # them for.
115 #
116 # Patches are applied in current directory.
117 #
118 # Bulk Patches should preferibly have the form of:
119 #
120 # ??_${ARCH}_foo.${EPATCH_SUFFIX}
121 #
122 # For example:
123 #
124 # 01_all_misc-fix.patch.bz2
125 # 02_sparc_another-fix.patch.bz2
126 #
127 # This ensures that there are a set order, and you can have ARCH
128 # specific patches.
129 #
130 # If you however give an argument to epatch(), it will treat it as a
131 # single patch that need to be applied if its a file. If on the other
132 # hand its a directory, it will set EPATCH_SOURCE to this.

1010 # sometimes the function call is _llseek or something) and steal the 2nd
1011 # parameter. here is an example:
1012 # root@vapier 0 pdv_unpack # strings hldsupdatetool.bin | grep lseek
1013 # lseek
1014 # root@vapier 0 pdv_unpack # strace -elseek ./hldsupdatetool.bin
