893 | |||
894 | <para> | ||
895 | You might find yourself repeating the same configurations for | ||
896 | a particular build or group of builds. | ||
897 | If so, rather than repeatedly editing your | ||
898 | <filename>local.conf</filename> and possibly your | ||
899 | <filename>bblayers.conf</filename>, you can set up a | ||
900 | custom directory that has your configurations, and then | ||
901 | point the OpenEmbedded build system to that directory to find | ||
902 | the configurations. | ||
903 | </para> | ||
904 | |||
905 | <para> | ||
906 | The OpenEmbedded build system uses the environment variable | ||
907 | <filename>TEMPLATECONF</filename> to point to the directory | ||
908 | from which it gathers configuration information that ultimately | ||
909 | ends up in the | ||
910 | <link linkend='build-directory'>Build Directory's</link> | ||
911 | <filename>conf</filename> directory. | ||
912 | By default, <filename>TEMPLATECONF</filename> points here: | ||
913 | <literallayout class='monospaced'> | ||
914 | TEMPLATECONF=${TEMPLATECONF:-meta-yocto/conf} | ||
915 | </literallayout> | ||
916 | This is the directory that the build system finds templates | ||
917 | with which to build some key configuration files. | ||
918 | If you look at this directory, you will see the | ||
919 | <filename>bblayers.conf.sample</filename>, | ||
920 | <filename>local.conf.sample</filename>, and | ||
921 | <filename>site.conf.sample</filename> configuration files. | ||
922 | The build system uses these files to form the respective | ||
923 | <filename>bblayers.conf</filename>, | ||
924 | <filename>local.conf</filename>, and the | ||
925 | <filename>site.conf</filename> configuration files it places in | ||
926 | the <filename>conf</filename> directory with the | ||
927 | Build Directory. | ||
928 | </para> | ||
929 | |||
930 | <para> | ||
931 | To override these default configuration files with | ||
932 | configurations you want used with every build, simply point the | ||
933 | <filename>TEMPLATECONF</filename> to your directory. | ||
934 | The <filename>TEMPLATECONF</filename> variable is set in the | ||
935 | <filename>.templateconf</filename> file, which is in the | ||
936 | top-level | ||
937 | <link linkend='source-directory'>Source Directory</link> | ||
938 | folder (e.g. <filename>poky</filename>). | ||
939 | Edit the <filename>.templateconf</filename> so that it points | ||
940 | to your directory. | ||
941 | Best practices dictate that you should keep your | ||
942 | template configuration directory in your custom distribution layer. | ||
943 | For example, suppose you have a layer named | ||
944 | <filename>meta-mylayer</filename> located in your home directory | ||
945 | and you want your template configuration directory named | ||
946 | <filename>myconf</filename>. | ||
947 | Changing the <filename>.templateconf</filename> as follows | ||
948 | causes the OpenEmbedded build system to look in your directory | ||
949 | and base its configuration files on the | ||
950 | <filename>*.sample</filename> configuration files it finds. | ||
951 | The final configuration files (i.e. | ||
952 | <filename>local.conf</filename> and | ||
953 | <filename>bblayers.conf</filename> ultimately still end up in | ||
954 | your Build Directory, but they are based on your | ||
955 | <filename>*.sample</filename> files. | ||
956 | <literallayout class='monospaced'> | ||
957 | TEMPLATECONF=${TEMPLATECONF:-meta-mylayer/myconf} | ||
958 | </literallayout> | ||
959 | </para> | ||
960 | |||
961 | <para> | ||
962 | Aside from the <filename>*.sample</filename> configuration files, | ||
963 | the <filename>conf-notes.txt</filename> also resides in the | ||
964 | default <filename>meta-yocto/conf</filename> directory. | ||
965 | The scripts that set up the build environment | ||
966 | (i.e. | ||
967 | <ulink url="&YOCTO_DOCS_REF_URL;#structure-core-script"><filename>&OE_INIT_FILE;</filename></ulink> | ||
968 | and | ||
969 | <ulink url="&YOCTO_DOCS_REF_URL;#structure-memres-core-script"><filename>oe-init-build-env-memres</filename></ulink>) | ||
970 | use this file to display BitBake targets as part of the script | ||
971 | output. | ||
972 | Customizing this <filename>conf-notes.txt</filename> file is a | ||
973 | good way to make sure your list of custom targets appears | ||
974 | as part of the script's output. | ||
975 | </para> | ||
976 | |||
977 | <para> | ||
978 | Here is output from either of the setup scripts by default: | ||
979 | <literallayout class='monospaced'> | ||
980 | $ source oe-init-build-env-memres | ||
981 | No port specified, using dynamically selected port | ||
982 | |||
983 | ### Shell environment set up for builds. ### | ||
984 | |||
985 | You can now run 'bitbake <target>' | ||
