Bug 3080

Removing the x32 layer and setting the default tune:

DEFAULTTUNE = "x86-64-x32"
baselib = "${@d.getVar('BASE_LIB_tune-' + (d.getVar('DEFAULTTUNE', True) or 'INVALID'), True) or 'lib'}"

Builds correctly with 2.16 eglibc and the 3.4 kernel.  

I did one additional step of using bitbake -c menuconfig linux-yocto on the kernel to enable CONFIG_X86_X32=y

This booted to and x32 based image!

I am going to work with Bruce to get a correct config fragment into the meta layer.

Adding the x32 layer
gives the following output

lserban@computer4:~/work/master/build$ bitbake core-image-sato
Pseudo is not present but is required, building this first before the main build
ERROR: ParseError at /home/lserban/work/master/meta-x32/images/core-image-core-x32.bb:8: Could not include required file recipes-core/images/core-image-core-x32.bb                                                          | ETA:  --:--:--

Summary: There were 2 ERROR messages shown, returning a non-zero exit code.

I will set the test as failed until the fix is commited

Thanks to Bruce

This is post RC1

For the test, you don't need to add the meta-x32 layer any longer.

I have these errors while using the steps above.

I didn't get any errors on bitbake core-image-minimal on Fedora 17, OpenSuse 12.2 and CentOS 6.3.

But it failed on eglibc compile on Ubuntu 12.04 x64, branch danny:

eglibc log.do_compile ubuntu2

I still need more information, and maybe access to that machine, I can not reproduce this issue.  I just tried again with a fresh build (no sstate).

My machine is 12.04.1 LTS with a 3.2.0-31 kernel.

Also, please note these compile failures are different!  The first one is a compile fail with a #error NF_pread and NR_pread64 both being defined.  The new error is in the make-syscalls.sh script with a bad subsititution, this could be a shell issue or missing dependency of somekind.  Again I would need to look directly at this build.

The new issue is related to make-syscalls.sh which has some bash'isms in it. I found that the systems QA is using has dash as default, while I had bash as default /bin/sh.  I checked with Khem and found that eglibc is currently not dash clean in all cases.

I am working on seeing what changes can be made, but currently a release note for x32 might be appropriate and make a note in the x32 Wiki page.

I think that /bin/sh -> dash is the default in Ubuntu (at least for the last 2 versions), I didn't do any change here.

stefans@ubuntu12:~$ ls -l /bin/sh
lrwxrwxrwx 1 root root 4 Aug  3 17:13 /bin/sh -> dash

Interestingly user shell is still bash:

stefans:x:1000:1000:Stefan,,,:/home/stefans:/bin/bash

After changing /bin/sh -> bash eglibc compile doesn't fail anymore, image builds fine, boots and kernel has the correct config fragment. Same for other distros (see comment 10).
