kvazaar is affected by three different build issues on PowerPC and related architectures: - On PowerPC64, the build fails due to the use of a deprecated vec_lvsl() function: strategies/altivec/picture-altivec.c: In function ‘reg_sad_altivec’: strategies/altivec/picture-altivec.c:43:5: error: vec_lvsl is deprecated for little endian; use assignment for unaligned loads and stores [-Werror=deprecated] perm1 = vec_lvsl(0, &data1[y * stride1]); ^~~~~ This bug has been reported upstream at: https://github.com/ultravideo/kvazaar/issues/172 - On PowerPC 8548, the build fails due to mixing AltiVec and E500 instructions: strategies/altivec/picture-altivec.c:1:0: error: AltiVec and E500 instructions cannot coexist This bug has been reported upstream at: https://github.com/ultravideo/kvazaar/issues/173 - On PowerPC e500mc, because Altivec is not supported on this target: strategies/altivec/picture-altivec.c:1:0: error: AltiVec not supported in this target This bug has been reported upstream at: https://github.com/ultravideo/kvazaar/issues/174 Fixes: http://autobuild.buildroot.net/results/486/486757f04bc73736b64d18c3298216280be897b1 http://autobuild.buildroot.net/results/45d/45d22c9f2f5b593bed286319105c82cbc3396835 http://autobuild.buildroot.net/results/76c/76c76191f84748326d76fe0cc89456a72738a06b Signed-off-by: Romain Naour <romain.naour@smile.fr> Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> |

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on Freenode IRC. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
