Lee,
I uninstalled libwebp-dev on my Debian Jessie installation and ran
./configure for xastir. It reported the Imagemagick/Graphicsmagick error.
I reinstalled libwebp-dev and again ran ./configure. This time there
wasn't an error and all options said YES.
Regards,
Ray vk2tv

The
names escape me now. When attempting to build Xastir in Ubuntu 15.10 the
configure script points to not finding key files that would normally be
provided by the dev packages for imagemagick or GraphicsMagick. With
respect to GraphicsMagick, I'm not sure exactly what this message
means...

???If this issue is also present in 16.04 this April I'm sure it will get

I bet dollars to donuts that there is a missing dependent library, and the
test is failing.
That jibes with Ray's experience with Debian Jessie - he said he installed
'missing dependencies' in order to resolve what appeared to be the same
problem.
Configure works by creating a small test program that
calls "WriteImage" and then tries to link that test program with
-lGraphicsMagick. If the link fails, it reports that the function does not
exist, but there are often other reasons for the failure.
Look in config.log and see what the linker is actually complaining about.
I'll
bet it's complaining about some other function not being defined when
linking
-lGraphicsMagick. Then the trick is to find what library provides *THAT*
and
why it hasn't already been added to LIBS.
Our configure script is supposed to use
GraphicsMagick-config --libs
to get the correct libs line to use. That, in turn, is supposed to return
a list of all "-l" arguments that should be used to link with
GraphicsMagick.
If there is something missing in that list, it could cause this problem.
Thanks - I forgot about config.log. I found this a few lines down from
the check for "WriteImage in lGraphicsMagick"
/usr/bin/ld: cannot find -lwebp
Hmm, webp, "Lossy compression of digital photographic images" - that sounds
like something GraphicsMagick might use - or need. The webp package was
installed but not libwebp-dev, so perhaps the dev package for
GraphicsMagick should be installing that as a dependency. I installed
libwebp-dev, and "presto", Configure found GM, and Xastir is built with
working online OSM maps. Thanks Tom!
Hey Dexter. In Kubuntu 15.10, install libwebp-dev. :-)
I'm not sure if libwebp-dev will fix Debian Jessie, however. I don't have
the means to try that now.
