Building --with-native-compilation on Ubuntu 18.04 LT

Building --with-native-compilation on Ubuntu 18.04 LT

[H. Dieter Wilhelm]

Hello Emacs

I'd like to compile Emacs with the --with-native-compilation support.
But configure was complaining about a missing libgccjit executable.  I
thought it a good idea to install libgccjit with the same version number
as the installed gcc: libgccjit-7-dev.

But now configure is complaining that libgccjit can't compile a test
program.

The only hint I found is on StackExchange with a recipe for Ubuntu 18.04
using gcc-10.  Do you know if it is really necessary to install such a
new version of gcc?  (A problem is that gcc-10 is not readily available
in the Ubuntu repo.)

Thank you

      Dieter

The problem with gcc 7 is known ant the author recommends gcc 9 or
newer:

https://akrl.sdf.org/gccemacs.html#orgde56122


It is a bit puzzling that there is no mention of native-comp / libgccjit
on INSTALL.

Thanks a lot Óscar :-) I'll immediately try gcc-9!

The documentation will grow (I hope)..

Have a good time

What exactly is the error message in config.log that corresponds to
this test?

No.

FWIW, I'm a happy user of GCC 7 and the corresponding libgccjit on a
Trisquel GNU/Linux box.

I reported the very same error in this list.

I think that the problem might be in the place where some files are
stored in Ubuntu.

A check with gcc-9 has to wait a bit, only gcc-8 is in the default repo
for Ubuntu 18.04.  And configure complained with gcc-8 and
libgccjit-8-dev as well.

See this file [last], it is how I do it on Debian which is

So you have migrated here finally?

Well, you came to the right place :)

Trisquel GNU/Linux ... based on Ubuntu with the non-free
stuff removed! [1]

Maybe you can do that with Debian by removing the "non-free"
words from /etc/apt/sources.list ... it should be that way,
at least! NixOS perhaps ...

He means it isn't necessary but don't you want it anyway?

What's the hesitation?

So the test program segfaults.  At this point, I would suggest taking
this up with the distro maintainers.

I didn't migrate anywhere, not AFAIK and not lately.

I don't want to mess with the preinstalled OS of this Dell laptop where
every piece of hardware is working as it was conceived to work.

You are not messing with the OS by installing software!
Or what do you mean?

But installing from the package archives of the respective OS version.
Unfortunately gcc-9 and -10 are not available on Ubuntu 18.04.  I'm
hesitant to upgrade the OS and likewise applying things like backports
or snap packages, which might work for the moment but might later bite
you back.

OK, right, I thought they/you had it as well.

I'm on Debian 11 and here libgcc-dev-10 is available out of
the ... repo.

Do you use a laptop?  (On all my other machines I installed Debian.)

Nope, here is a photo of what I use:

with some details:

  https://dataswamp.org/~incal/ebchw/COMPUTER

I have a laptop lying around tho, but I think I'll put OpenBSD
on that since some people say it is more secure (not 100% it
is myself in practice tho) and I don't plan to use it
creatively anyway ...

But ... where does that come in? You had a bad experience
running Debian on laptops?

Nice! :-) Used to fiddle mainly with workstations but now I switched,
mainly, to the wing chair in the living room and thus...

Yes, sadly, it seems that esp. for newer laptops there are always driver
and power management (for example suspend to RAM) issues.

I recommend:

DragonflyBSD
https://www.dragonflybsd.org

As it has superior HAMMER file system.

Okay ... not good.

I didn't know there was a difference actually with Debian with
respect to workstations/laptop computers ...

Okay, what's so superior about it?

  DragonFly includes many useful features that differentiate
  it from other operating systems in the same class.
  
  The most prominent one is HAMMER, our modern high
  performance filesystem with built-in mirroring and historic
  access functionality.

When a notebook battery gets empty because of lack of  electricity the
file system retains its integrity. See:

Finally I compiled Emacs on my Debian 10 server.  Aaaaand..

native compilation is working there (with gcc-8). :-)
