{"@context":"https://schema.org","@type":"DiscussionForumPosting","headline":"Zephyr main branch requires 0.16.x SDK (Intel toolchain change)","articleBody":"Since zephyr commit https://github.com/zephyrproject-rtos/zephyr/commit/9fc99928caf04c3ae78 and https://github.com/zephyrproject-rtos/zephyr/commit/49d0ad55206aa, the Zephyr main branch is not compatible with the Zephyr SDK 0.15.x anymore, it now requires 0.16.x. The Zephyr main branch now depends on different (and correct) toolchain names which are not present in 0.15.x\r\n\r\n -\u003e this requires some \"infrastructure\" updates\r\n\r\nEvery PR trying to build the Zephyr main branch (a.k.a. \"zmain\") started to fail like this, example in https://github.com/thesofproject/sof/actions/runs/4984592530\r\n\r\n```\r\nCMake Error at /zep_workspace/zephyr/cmake/compiler/gcc/target.cmake:12 (message):\r\n  C compiler\r\n  /home/cwd_user/zephyr-sdk-0.15.2/xtensa-intel_ace15_mtpm_zephyr-elf/bin/xtensa-intel_ace15_mtpm_zephyr-elf-gcc\r\n  not found - Please check your toolchain installation\r\n```\r\n\r\n- [ ] Fixing this for Linux compilation should be more or less a one-line change in the `zephyr/docker-run.sh` script (example in previous commit 11441d85409)\r\n\r\n- [ ] Change ubuntu-20.04 -\u003e ubuntu-22.04 in the 2 files `.github/workflows/*zephyr.yml` to stay in sync with https://github.com/zephyrproject-rtos/docker-image/pkgs/container/zephyr-build\r\n\r\n- [ ] The Windows compilation that we've enjoyed thanks to @aborisovich's heroic work (commit df1ba222306d) is unfortunately a bit more complicated.\r\n\r\nNote upgrading will also help with OpenSSL 1.x removal where this has already been discussed:\r\n- https://github.com/thesofproject/rimage/pull/157 \r\n","author":{"url":"https://github.com/marc-hb","@type":"Person","name":"marc-hb"},"datePublished":"2023-05-15T20:59:58.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":3},"url":"https://github.com/7614/sof/issues/7614"}
