'ct-ng saveconfig' dropped some useful settings like package versions, so I used
the full .config. I let you reformat the config file as you like before
applying.

Best regards,
Benoît

Nice to see our first sample ending in -gnueabihf! :-)

Yes, that's expected. LAtest versions being at the top of the choices
means they are the defaults for those choices, so do not get saved in
defconfig files.

The rational for using defconfig is two-fold:
  - avoid the churn when porting to a newer set of options (eg. when
    updating ct-ng)
  - have samples that use the latest version of a component always
    use the latest version of that component. That should help catch
    breakage when adding new versions, as the bleeding-edge sample
    would cach it. No, I haven't had time to add such sample for now.

If you want to add a sample that is using the latest version of a
component, and it is the last version available, then you have to
explicitly edit the sample and manually add the corresponding
symbol. Tedious, but not insurmountable, I think.

So, I'll save the sample as a defconfig, but pinpoint the versions.

Also, next time, please remove the debugging stuff from the sample:
  - no CT_DEBUG_CT
  - no CT_COMPLIBS_CHECK

I've unchecked building documentation, as it fails here on my machine.
Something to do with pdflatex going nuts...

I'm doing a last build-test run, and I'll push that sample shortly.

Thank you!

Yann E. MORIN.

Is that really 'neon' ? I thought its gcc name was something like
'neon-vfpv4' (or v3?)...

Can you explain what this specific specs are supposed to achieve (sorry,
I am not fluent in gcc's specs) and why they are needed?

Ah... The multi-arch debianism... :-(

Besides this patch, should we take care of this internally, and set it
whenever the gcc is a Linaro version?

Yann E. MORIN.

OK, forget it, I need some rest. Seems it's unrelated to Debian multi-arch.

But what does it mean to have a "single DSO with optimizations for multiple
architectures" ?

I'm guessing it is the STT_GNU_IFUNC thing.

Yes, for Cortex-A8/9 (VFPv3).

'neon-vfpv4' exists, but it is for CortexA5/15 (VFPv4).

I had taken that from the Sourcery build script at the time of the fork with
Linaro in order to use exactly the same build options as them, and I have kept
this since then.

It means:
 - Pass '-fverbose-asm' to the subprocess if '-save-temps' was given to GCC. If
   the user asks to keep the temporary build files, it is in order to read them,
   so making them verbose helps for debug purposes.
 - Pass '-funwind-tables' to the subprocess if neither '-funwind-tables' nor
   '-fno-unwind-tables' nor '-mabi=*' nor '-ffreestanding' nor '-nostdlib' was
   given to GCC. This seems to also be more for debug purposes than something
   really needed.

Best regards,
Benoît

This is also something I took from the Sourcery build script.

I think that Johannes' guess is the right one. As we are building for only a
single architecture (no multi-lib), there is no reason to enable this multi-arch
DSO optimization mechanism, which could only slow things down.

This is probably not strictly needed, but better without multi-lib (which does
not work for ARM anyway). I think that this option could be automated in CT-NG
for (e)glibc in all cases without multi-lib.

Best regards,
Benoît
