19 # must be an integer greater than zero.

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

111 # This function is for bulk patching, or in theory for just one
112 # or two patches.
113 #
114 # It should work with .bz2, .gz, .zip and plain text patches.
115 # Currently all patches should be the same format.
116 #
117 # You do not have to specify '-p' option to patch, as it will
118 # try with -p0 to -p5 until it succeed, or fail at -p5.
119 #
120 # Above EPATCH_* variables can be used to control various defaults,
121 # bug they should be left as is to ensure an ebuild can rely on
122 # them for.
123 #
124 # Patches are applied in current directory.
125 #
126 # Bulk Patches should preferibly have the form of:
127 #
128 # ??_${ARCH}_foo.${EPATCH_SUFFIX}
129 #
130 # For example:
131 #
132 # 01_all_misc-fix.patch.bz2
133 # 02_sparc_another-fix.patch.bz2
134 #
135 # This ensures that there are a set order, and you can have ARCH
136 # specific patches.
137 #
138 # If you however give an argument to epatch(), it will treat it as a
139 # single patch that need to be applied if its a file. If on the other
140 # hand its a directory, it will set EPATCH_SOURCE to this.

1077 # parameter. here is an example:
1078 # root@vapier 0 pdv_unpack # strings hldsupdatetool.bin | grep lseek
