OS:      LINUX - DEBIAN - SARGE
lib:     CAIRO 1.2.6

I am trying to install gtkmm-2.10.x from source, for that I need to
install cairo 1.2.6, as it is a prerequiset. However after typing './
configure' I get this error message:
checking for cairo's PNG backend...
./configure: line 24784: --exists: command not found
./configure: line 24784: --exists: command not found
./configure: line 24784: --exists: command not found
configure: WARNING: Could not find libpng in the pkg-config search
path
checking whether cairo's PNG backend could be enabled... no
configure: error: requested PNG backend could not be enabled

I have installed ZLIB 1.2.3, PNG 1.2.16 and using apt-get I installed
libpng12-dev, but I am still getting the same message, what else do I
need to do?

Thanks, that's helpful.

Is the source a deb-src package?  Did you install the source package
with apt-get/aptitude/synaptic?  Which?  Or did you DL a tarball from
somewhere?  If so, where?

I know, this is frustrating stuff and any of the three should/can be
made to work.  The devil's in the details.

[Also a caveat: I'm no Java person.  I'm just trying to help.]

aptitude search libpng shows:

Which is a lot of ++confusing stuff to me.

"aptitude search cairo" reports nothing (I run sarge too).  Where did
you get it from?

i A libpng12-0                           - PNG library - runtime

Is that installed?

You might try IRC and ask the wizards in #java or #debian.  They may
be able to sort this out in real time.  Welcome to the bleeding edge.
You may be trying to do something no-one here's trying to do.

BTW, "aptitude search gtkmm" yeilds:

which may, or may not, be useful.  :-P

I don't have the source for gtkmm-2.10, but I'd guess that you need to
specify where libpng is installed:

./configure --with-libpng=/usr/local/lib

If you have a BIG need for more modern software than what's in Sarge,
you should use either Etch or Sid because all these technicalities have
been figured out for those distributions.
