Hello Lars,

I am doing following configure:

config.status: executing src/epaths.h commands
config.status: executing src/.gdbinit commands
config.status: executing doc/emacs/emacsver.texi commands
config.status: executing etc-refcards-emacsver.tex commands
<DEV> root [ /sources/emacs ]# grep imagemagick configure
with_imagemagick
  --without-imagemagick   don't compile with ImageMagick image support
# Check whether --with-imagemagick was given.
if test "${with_imagemagick+set}" = set; then :
  withval=$with_imagemagick;
     with_imagemagick=$with_features
  if test "${with_imagemagick}" != "no"; then
  Does Emacs use imagemagick?                             ${HAVE_IMAGEMAGICK}
<DEV> root [ /sources/emacs ]# ./configure --prefix=/package/text/emacs-26.0.50 
--with-sound=alsa --with-modules --with-x --with-x-toolkit=lucid 
--without-gconf --without-gsettings --without-libsystemd --without-dbus 
--without-pop --with-mailutils --with-imagemagick

And I still do not get imagemagick, it says "Does
Emacs use imagemagick = no", even if I do have
imagemagick here.

Before it was just compiling fine. Then I chose
not to compile it, due to some crashes, but
recently, I do not use --without-imagemagick and
it is not compiling for some reason, I do not know
why.

Anyway I will try the version from Git today, to
see how SVG works.
