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

46 need to have a "fake" dynamic lib in /usr/lib,
47 otherwise we run into linking problems.

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

714 # new convenience patch wrapper function to eventually replace epatch(),
715 # $PATCHES, $PATCHES1, src_unpack:patch, src_unpack:autopatch and
716 # /usr/bin/patch
717 # Features:
718 # - bulk patch handling similar to epatch()'s
719 # - automatic patch level detection like epatch()'s
720 # - automatic patch uncompression like epatch()'s
721 # - doesn't have the --dry-run overhead of epatch() - inspects patchfiles
722 # manually instead
723 # - once I decide it's production-ready, it'll be called from base_src_unpack
724 # to handle $PATCHES to avoid defining src_unpack just to use xpatch
725
726 # accepts zero or more parameters specifying patchfiles and/or patchdirs
727
728 # known issues:
729 # - only supports unified style patches (does anyone _really_ use anything
730 # else?)
731 # - because it doesn't use --dry-run there is a risk of it failing
732 # to find the files to patch, ie detect the patchlevel, properly. It doesn't use
733 # any of the backup heuristics that patch employs to discover a filename.
734 # however, this isn't dangerous because if it works for the developer who's
735 # writing the ebuild, it'll always work for the users, and if it doesn't,
736 # then we'll fix it :-)
737 # - no support as yet for patches applying outside $S (and not directly in $WORKDIR).
