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

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

109 #
110 # It should work with .bz2, .gz, .zip and plain text patches.
111 # Currently all patches should be the same format.
112 #
113 # You do not have to specify '-p' option to patch, as it will
114 # try with -p0 to -p5 until it succeed, or fail at -p5.
115 #
116 # Above EPATCH_* variables can be used to control various defaults,
117 # bug they should be left as is to ensure an ebuild can rely on
118 # them for.
119 #
120 # Patches are applied in current directory.
121 #
122 # Bulk Patches should preferibly have the form of:
123 #

125 #
126 # For example:
127 #
128 # 01_all_misc-fix.patch.bz2
129 # 02_sparc_another-fix.patch.bz2
130 #
131 # This ensures that there are a set order, and you can have ARCH
132 # specific patches.
133 #
134 # If you however give an argument to epatch(), it will treat it as a
135 # single patch that need to be applied if its a file. If on the other
136 # hand its a directory, it will set EPATCH_SOURCE to this.

1014 # sometimes the function call is _llseek or something) and steal the 2nd
1015 # parameter. here is an example:
1016 # root@vapier 0 pdv_unpack # strings hldsupdatetool.bin | grep lseek
1017 # lseek
1018 # root@vapier 0 pdv_unpack # strace -elseek ./hldsupdatetool.bin
