gmp configure script is pretty good at auto detecting the ABI and the tune flags that need to be passes to the compiler. However, the user provided flags (CFLAGS, CXXFLAGS, CPPFLAGS) take precedence and the ABI detection may fail, leading to configure errors like the one below: | configure: error: Oops, mp_limb_t is 32 bits, but the assembler code | in this configuration expects 64 bits. | You appear to have set $CFLAGS, perhaps you also need to tell GMP the | intended ABI, see "ABI and ISA" in the manual. One solution would be to change the recipe and add the ABI manually, or let gmp do the job. So, this patch will: * allow the configure process to auto-detect the ABI and tune flags properly; * append our flags to the detected ones; [YOCTO #5783] (From OE-Core rev: 8339b9ac16e7d3206de21a204beffaae5203adbb) Signed-off-by: Laurentiu Palcu <laurentiu.palcu@intel.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
Poky
Poky is an integration of various components to form a complete prepackaged build system and development environment. It features support for building customised embedded device style images. There are reference demo images featuring a X11/Matchbox/GTK themed UI called Sato. The system supports cross-architecture application development using QEMU emulation and a standalone toolchain and SDK with IDE integration.
Additional information on the specifics of hardware that Poky supports is available in README.hardware. Further hardware support can easily be added in the form of layers which extend the systems capabilities in a modular way.
As an integration layer Poky consists of several upstream projects such as BitBake, OpenEmbedded-Core, Yocto documentation and various sources of information e.g. for the hardware support. Poky is in turn a component of the Yocto Project.
The Yocto Project has extensive documentation about the system including a reference manual which can be found at: http://yoctoproject.org/documentation
OpenEmbedded-Core is a layer containing the core metadata for current versions of OpenEmbedded. It is distro-less (can build a functional image with DISTRO = "nodistro") and contains only emulated machine support.
For information about OpenEmbedded, see the OpenEmbedded website: http://www.openembedded.org/
Where to Send Patches
As Poky is an integration repository, patches against the various components should be sent to their respective upstreams.
bitbake: bitbake-devel@lists.openembedded.org
meta-yocto: poky@yoctoproject.org
Most everything else should be sent to the OpenEmbedded Core mailing list. If in doubt, check the oe-core git repository for the content you intend to modify. Before sending, be sure the patches apply cleanly to the current oe-core git repository. openembedded-core@lists.openembedded.org
Note: The scripts directory should be treated with extra care as it is a mix of oe-core and poky-specific files.
