2078
2079 <para>
2080 Proper built-in support for selecting BlueZ 5.x in preference
2081 to the default of 4.x now exists.
2082 To use BlueZ 5.x, simply add "bluez5" to your
2083 <link linkend='var-DISTRO_FEATURES'><filename>DISTRO_FEATURES</filename></link>
2084 value.
2085 If you had previously added append files
2086 (<filename>*.bbappend</filename>) to make this selection, you can
2087 now remove them.
2088 </para>
2089
2090 <para>
2091 Additionally, a
2092 <link linkend='ref-classes-bluetooth'><filename>bluetooth</filename></link>
2093 class has been added to make selection of the appropriate bluetooth
2094 support within a recipe a little easier.
2095 If you wish to make use of this class in a recipe, add something
2096 such as the following:
2097 <literallayout class='monospaced'>
2098 inherit bluetooth
2099 PACKAGECONFIG ??= "${@bb.utils.contains('DISTRO_FEATURES', 'bluetooth', '${BLUEZ}', '', d)}
2100 PACKAGECONFIG[bluez4] = "--enable-bluetooth,--disable-bluetooth,bluez4"

2108
2109 <para>
2110 SSL 3.0 is now disabled when building OpenSSL.
2111 Disabling SSL 3.0 avoids any lingering instances of the POODLE
2112 vulnerability.
2113 If you feel you must re-enable SSL 3.0, then you can add an
2114 append file (<filename>*.bbappend</filename>) for the
2115 <filename>openssl</filename> recipe to remove "-no-ssl3"
2116 from
2117 <link linkend='var-EXTRA_OECONF'><filename>EXTRA_OECONF</filename></link>.

2122 <title>Default Sysroot Poisoning</title>
2123
2124 <para>
2125 <filename>gcc's</filename> default sysroot and include directories
2126 are now "poisoned".
2127 In other words, the sysroot and include directories are being
2128 redirected to a non-existent location in order to catch when
2129 host directories are being used due to the correct options not
2130 being passed.
2131 This poisoning applies both to the cross-compiler used within the
2132 build and to the cross-compiler produced in the SDK.
2133 </para>
2134
2135 <para>
2136 If this change causes something in the build to fail, it almost
2137 certainly means the various compiler flags and commands are not
2138 being passed correctly to the underlying piece of software.
2139 In such cases, you need to take corrective steps.

2158 One of the improvements is to attempt to run "make clean" during

2161 Some software packages do not provide a working clean target
2162 within their make files.
