16
17 # This function generate linker scripts in /usr/lib for dynamic
18 # libs in /lib. This is to fix linking problems when you have
19 # the .so in /lib, and the .a in /usr/lib. What happens is that
20 # in some cases when linking dynamic, the .a in /usr/lib is used
21 # instead of the .so in /lib due to gcc/libtool tweaking ld's
22 # library search path. This cause many builds to fail.
23 # See bug #4411 for more info.
24 #
25 # To use, simply call:
26 #
27 # gen_usr_ldscript libfoo.so
28 #
29 # Note that you should in general use the unversioned name of
30 # the library, as ldconfig should usually update it correctly
31 # to point to the latest version of the library present.
32 #

41 /* GNU ld script
42 Because Gentoo have critical dynamic libraries
43 in /lib, and the static versions in /usr/lib, we
44 need to have a "fake" dynamic lib in /usr/lib,
45 otherwise we run into linking problems.
46 See bug #4411 on http://bugs.gentoo.org/ for
47 more info. */

98 # This function is for bulk patching, or in theory for just one
99 # or two patches.
100 #
101 # It should work with .bz2, .gz, .zip and plain text patches.
102 # Currently all patches should be the same format.
103 #
104 # You do not have to specify '-p' option to patch, as it will
105 # try with -p0 to -p5 until it succeed, or fail at -p5.
106 #
107 # Above EPATCH_* variables can be used to control various defaults,
108 # bug they should be left as is to ensure an ebuild can rely on
109 # them for.
110 #
111 # Patches are applied in current directory.
112 #
113 # Bulk Patches should preferibly have the form of:
114 #
115 # ??_${ARCH}_foo.${EPATCH_SUFFIX}
116 #
117 # For example:
118 #
119 # 01_all_misc-fix.patch.bz2
120 # 02_sparc_another-fix.patch.bz2
121 #
122 # This ensures that there are a set order, and you can have ARCH
123 # specific patches.
124 #
125 # If you however give an argument to epatch(), it will treat it as a
126 # single patch that need to be applied if its a file. If on the other
127 # hand its a directory, it will set EPATCH_SOURCE to this.
