You had no conf/local.conf file. This configuration file has therefore been

created for you with some default values. You may wish to edit it to use a

different MACHINE (target hardware) or enable parallel build options to take

advantage of multiple cores for example. See the file for more information as

common configuration options are commented.

You had no conf/bblayers.conf file. The configuration file has been created for

you with some default values. To add additional metadata layers into your

configuration please add entries to this file.

The Yocto Project has extensive documentation about OE including a reference

manual which can be found at:

    http://yoctoproject.org/documentation

For more information about OpenEmbedded see their website:

    http://www.openembedded.org/

### Shell environment set up for builds. ###

You can now run 'bitbake <target>'

Common targets are:

    core-image-minimal

    core-image-sato

    meta-toolchain

    adt-installer

    meta-ide-support

You can also run generated qemu images with a command like 'runqemu qemux86'

-x language

Specify explicitly the language for the following input files (rather than letting the compiler choose a default based on the file name suffix). This option applies to all following input files until the next -x option. Possible values for language are:

c  c-header  c-cpp-output

c++  c++-header  c++-cpp-output

objective-c  objective-c-header  objective-c-cpp-output

objective-c++ objective-c++-header objective-c++-cpp-output

assembler  assembler-with-cpp

ada

f77  f77-cpp-input f95  f95-cpp-input

java

-o file

Place output in file file. This applies regardless to whatever sort of output is being produced, whether it be an executable file, an object file, an assembler file or preprocessed C code.

If -o is not specified, the default is to put an executable file in a.out, the object file for source.suffix in source.o, its assembler file in source.s, a precompiled header file in source.suffix.gch, and all preprocessed C source on standard output.
