Stuart,

basically Yocto is a build system for embedded Linux distributions.

I am trying to build one for a Xilinx US+ MPSoC SOC which has a quad Cortex-A53 APU i.e. aarch64. The tool chain comes from Xilinx and is basically a repackaged Linaro 5.2 (aarch64-linux-gnu-). The host on which Yocto runs is Ubuntu 16.04. The target OS is a Linux distribution built specifically for the Xilinx SOC target. Does this help? If you want more info please ask.

Yocto automates the process of creating a sysroot and configuring and making each item of included software. In this case it unpacks the tar ball of the 16-09 release, then configures it using the configure script included in the release and then calls make image.

Here is the recipe (as they are called in Yocto) that is used.

Hello Peter, Could you elaborate a bit more? I've never come across Yocto, and would need to know what toolchains, librarieis, binutils, etc, you are using. Knowing what OS/platform is being used is also important.

Hello Peter, I've tried reproducing the issue, but without any luck. I tried checking out the morty branch of "poky"

To give you some idea:

$ bitbake -v openjdk-8 -c Usage: bitbake [options] [recipename/target recipe:do_task ...]

Executes the specified task (default is 'build') for a given set of target recipes (.bb files). It is assumed there is a conf/bblayers.conf available in cwd or in BBPATH which will provide the layer, BBFILES and other configuration information.

bitbake: error: -c option requires 1 argument stumon01@e109365:~/repos/poky/build$ bitbake -v openjdk-8 -c compile WARNING: Host distribution "Ubuntu-16.10" has not been validated with this version of the build system; you may possibly experience unexpected failures. It is recommended that you use a tested distribution.

Summary: There was 1 WARNING message shown. Summary: There was 1 ERROR message shown, returning a non-zero exit code.

Looking at the recipe, it seems reasonable, if the overrides for LD, etc, are reasonable. I'd guess there may be more going on than what you've presented - I don't know the contents of the other files that define the LDFLAGS property would be.

I've put Riku on CC as apparently he has worked with Yocto.

I have got to the bottom of the problem, but I don't yet have the solution There is a difference between the versions of the Linaro GNU tool chains at the point release level. The current Linaro g++ silently ignores the "-Wl" command line option, the version supplied by Xilinx generates an error. However both silently ignore "-Wl,".

Stuart, thanks very much for helping out. I have not been working on this issue today, but will return to it in the morning and see if I can get some more details to help sort it out. Peter

Hello Peter, I've tried reproducing the issue, but without any luck. I tried checking out the morty branch of "poky"

To give you some idea:

$ bitbake -v openjdk-8 -c Usage: bitbake [options] [recipename/target recipe:do_task ...]

Executes the specified task (default is 'build') for a given set of target recipes (.bb files). It is assumed there is a conf/bblayers.conf available in cwd or in BBPATH which will provide the layer, BBFILES and other configuration information.

bitbake: error: -c option requires 1 argument stumon01@e109365:~/repos/poky/build$ bitbake -v openjdk-8 -c compile WARNING: Host distribution "Ubuntu-16.10" has not been validated with this version of the build system; you may possibly experience unexpected failures. It is recommended that you use a tested distribution. Loading cache: 100% |####################################################################### |#################################################################| Time: 0:00:00 Loaded 1335 entries from dependency cache.

ERROR: Nothing PROVIDES 'openjdk-8'

Summary: There was 1 WARNING message shown. Summary: There was 1 ERROR message shown, returning a non-zero exit code.

Looking at the recipe, it seems reasonable, if the overrides for LD, etc, are reasonable. I'd guess there may be more going on than what you've presented - I don't know the contents of the other files that define the LDFLAGS property would be.

I've put Riku on CC as apparently he has worked with Yocto.

BR, Stuart

Hello Peter, Could you elaborate a bit more? I've never come across Yocto, and would need to know what toolchains, librarieis, binutils, etc, you are using. Knowing what OS/platform is being used is also important.

New to openjdk, apologies if this is obvious. I am trying to build the above as downloaded in source form from https://urldefense.proofpoint.com/v2/url?u=http-3A__openjdk.linaro.org_&... for Linux aarch64 as part of a Yocto distribution i.e. “bitbake -v openjdk-8 -c compile” and am getting the compile error shown below, I’m guessing that this is something to do with a Makefile somewhere (not sure) as -Wl appears to be passed to the compiler without the usual , and option. Any ideas how to fix?
