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

47 otherwise we run into linking problems.

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