fatal error: gnu/stubs-soft.h: No such file or directory

[davidlawson]

I'm getting the following error when compiling for a Cubox-i:

| In file included from .../build/tmp/sysroots/cubox-i/usr/include/features.h:389:0,
|                  from .../build/tmp/sysroots/cubox-i/usr/include/sys/types.h:25,
|                  from pkg/runtime/cgo/cgo.go:26:
| .../build/tmp/sysroots/cubox-i/usr/include/gnu/stubs.h:7:29: fatal error: gnu/stubs-soft.h: No such file or directory
|  # include <gnu/stubs-soft.h>
|                              ^
| compilation terminated.

I'm pretty sure my image is supposed to be using hard floats.

Which recipe are you building when it errors?

I'm building for an ATSAMA5D33. My system uses hard floats and does not have gnu/stubs-soft.h either.

My Machine File has these lines in it: require conf/machine/include/tune-cortexa5.inc DEFAULTTUNE = "cortexa5thf"

[davidlawson]

just golang-cross. https://github.com/Freescale/meta-fsl-arm-extra/blob/master/conf/machine/cubox-i.conf includes https://github.com/Freescale/meta-fsl-arm/blob/master/conf/machine/include/imx-base.inc which contains DEFAULTTUNE_mx6 ?= "cortexa9hf-neon"

[celledge]

I'm not sure what to suggest without trying to build for the board myself. As you can see from the recipes I'm just sourcing the gcc-4.8 recipe from meta with a few modifications to have it build the go language support instead. At this point I would have to dig into what assumptions the compiler is making and why.

I'm not yet familiar with that process so, you will probably be better off digging around yourself if you want an answer anytime soon.

I'm hitting the same error here with my cubieboard 2 build, any hints on how to solve this?

[fbertux]

Hi! I'm trying to use this layer with poky version fido and I got the same error. Any update on this?

[whirm]

I was forwarded this discussion: http://patchwork.openembedded.org/patch/93139/ but I haven't had time to read it closely yet.

[fbertux]

I made some modifications on make.bash script to set the correct CFLAGS for CC_FOR_TARGET. Can you try use https://github.com/fbertux/meta-golang on branch fido and test if compile?

[whirm]

@fbertux I'm using poky fido and it's building gcc-4.9, so I've added recipes for it: https://github.com/whirm/meta-golang/tree/float_fix And I'm still getting the error when building: http://paste.debian.net/204676/

[fbertux]

@whirm I'm able to work on this next monday. I updated my branch fido to be more simple. The error "gnu/stubs-soft.h: No such file or directory" I fixed using the variable ${TARGET_CC_ARCH} to set correct cflags. I'm using wandboard-solo with hard float. If you won't get fix the error next week I can test using a build for cubieboard.

[whirm]

@fbertux I've rebased my branch and removed all non-necessary layers just in case, still getting the error: http://paste.debian.net/205528/ Let me know if I can help with anything. Thanks!

[fbertux]

@whirm Try run bitbake golang-cross and check if appears the same error.

[whirm]

I rebased and it works now! I haven't tried to compile anything yet though. Tried executing the native go binary and it seems to run fine.

I'll try to build syncthing with it ASAP.

Thanks!

[whirm]

@fbertux Is the example recipe working for you? I tried it and gccgo-cross fails with the same with the same soft-float error.

http://paste.debian.net/221022/ http://paste.debian.net/221023/

I'm running on your fido branch with the gcc-4.9 recipes on top.

[fbertux]

@whirm Only golang-cross is working, I'm still working on gccgo.

[whirm]

I see, thanks!

Those errors are due missing toolchain flags (TOOLCHAIN_OPTIONS, IRRC) for the compiler. This is not related to the layer.

[celledge]

I'm sorry, but this really appears to be a toolchain issue. Either something is misconfigured for your target platform or something funny is happening in gcc. I don't have much experience with either of these topics, so you might be better off seeing if you can manually build a gccgo toolchain for your intended target outside of yocto.

[celledge]

If this problem is still happening, you can try the bbappend branch of meta-golang. It is now based on gcc-4.9.2, and I cleaned up a few target CC flag issues that were happening.
