19 # This function generate linker scripts in /usr/lib for dynamic
20 # libs in /lib. This is to fix linking problems when you have
21 # the .so in /lib, and the .a in /usr/lib. What happens is that
22 # in some cases when linking dynamic, the .a in /usr/lib is used
23 # instead of the .so in /lib due to gcc/libtool tweaking ld's
24 # library search path. This cause many builds to fail.
25 # See bug #4411 for more info.
26 #
27 # To use, simply call:
28 #
29 # gen_usr_ldscript libfoo.so
30 #
31 # Note that you should in general use the unversioned name of
32 # the library, as ldconfig should usually update it correctly
33 # to point to the latest version of the library present.

44 Because Gentoo have critical dynamic libraries
45 in /lib, and the static versions in /usr/lib, we
46 need to have a "fake" dynamic lib in /usr/lib,
47 otherwise we run into linking problems.

100 # This function is for bulk patching, or in theory for just one

102 #
103 # It should work with .bz2, .gz, .zip and plain text patches.
104 # Currently all patches should be the same format.
105 #
106 # You do not have to specify '-p' option to patch, as it will
107 # try with -p0 to -p5 until it succeed, or fail at -p5.
108 #
109 # Above EPATCH_* variables can be used to control various defaults,
110 # bug they should be left as is to ensure an ebuild can rely on
111 # them for.
112 #
113 # Patches are applied in current directory.
114 #
115 # Bulk Patches should preferibly have the form of:
116 #
117 # ??_${ARCH}_foo.${EPATCH_SUFFIX}
118 #
119 # For example:
120 #
121 # 01_all_misc-fix.patch.bz2
122 # 02_sparc_another-fix.patch.bz2
123 #
124 # This ensures that there are a set order, and you can have ARCH
125 # specific patches.
126 #
127 # If you however give an argument to epatch(), it will treat it as a
128 # single patch that need to be applied if its a file. If on the other
129 # hand its a directory, it will set EPATCH_SOURCE to this.
