47 # This function generate linker scripts in /usr/lib for dynamic
48 # libs in /lib. This is to fix linking problems when you have
49 # the .so in /lib, and the .a in /usr/lib. What happens is that
50 # in some cases when linking dynamic, the .a in /usr/lib is used
51 # instead of the .so in /lib due to gcc/libtool tweaking ld's
52 # library search path. This cause many builds to fail.
53 # See bug #4411 for more info.
54 #
55 # To use, simply call:
56 #
57 # gen_usr_ldscript libfoo.so
58 #
59 # Note that you should in general use the unversioned name of
60 # the library, as ldconfig should usually update it correctly
61 # to point to the latest version of the library present.

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

140 # Currently all patches should be the same format.
141 #
142 # You do not have to specify '-p' option to patch, as it will
143 # try with -p0 to -p5 until it succeed, or fail at -p5.
144 #
145 # Above EPATCH_* variables can be used to control various defaults,
146 # bug they should be left as is to ensure an ebuild can rely on
147 # them for.
148 #
149 # Patches are applied in current directory.
150 #
151 # Bulk Patches should preferibly have the form of:
152 #
153 # ??_${ARCH}_foo.${EPATCH_SUFFIX}
154 #
155 # For example:
156 #
157 # 01_all_misc-fix.patch.bz2
158 # 02_sparc_another-fix.patch.bz2
159 #
160 # This ensures that there are a set order, and you can have ARCH
161 # specific patches.
162 #
163 # If you however give an argument to epatch(), it will treat it as a
164 # single patch that need to be applied if its a file. If on the other
165 # hand its a directory, it will set EPATCH_SOURCE to this.
