troubles compiling emacs26.1 on ubuntu18.04

[Le TeXnicien de Surface]

hello all

I'm trying to compile emacs26.1 on my ubuntu18.04
the configuration stage works well
I've just got a warning about GTK+ and a possible crash
in case of many instances
The make phase stalls with this message:

<end of make message>
   CCLD     temacs
//usr/lib/x86_64-linux-gnu/libpangoft2-1.0.so.0 :

</end of make message>
where "référence indéfinie vers" means "undefined reference to"

any hint would be greatly appreciated

many thanks in advance

The default build has too many dependencies.  If you want to get
something compiled without much hassle just disable dependencies in
the build.

It looks like you are using libcairo, which is experimental.
What options are you using for ./configure?

Look at ./configure --help

./configure --help | grep -i cairo
  --with-cairo            compile with Cairo drawing (experimental)
    CAIRO_CFLAGS
                  C compiler flags for CAIRO, overriding pkg-config
                    CAIRO_LIBS  linker flags for CAIRO, overriding pkg-config

Also try a lighter toolkit.

--with-x-toolkit=KIT (KIT one of: yes or gtk, gtk2, gtk3, lucid or athena, motif, no)

Try --with-x-toolkit=lucid and if that doesn't work you can still use
--with-x-toolkit=no (terminal only).

--with-sound=no is also worth trying.

wget http://ftp.gnu.org/gnu/emacs/emacs-26.1.tar.xz
tar xJvf emacs-26.1.tar.xz
cd emacs-26.1
./configure --help
./configure --prefix=/usr/local ; make ; make install

You may also want to look at this thread.  There libpng was the problem.

It appears that cairo is not used by default with what I've got.

that did the trick! I've compiled with gtk3 and it worked.

many thanks

Then what did make it incorrectly guess the toolkit to build with?  did
it try to use gtk2?  If so why?  Other (absent or silent) users might
risk to be bothered by this maybe.
