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:

v libpng-dev -
p libpng-sixlegs-java - Java package to read and display PNG images
i A libpng10-0 - PNG library, older version - runtime
p libpng10-dev - PNG library, older version - development
i A libpng12-0 - PNG library - runtime
v libpng12-0-dev -
p libpng12-dev - PNG library - development
p libpng2 - PNG library, older version - runtime
p libpng2-dev - PNG library, older version - development
p libpng3 - PNG library - runtime
p libpng3-dev - PNG library - development, compatibility packa
v libpngwriter -
v libpngwriter-dev -
p libpngwriter0 - easy to use graphics library (runtime)
p libpngwriter0-dev - easy to use graphics library (development)

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:

v gtkmm-doc -
c libgtkmm-2.4-1 - C++ wrappers for GTK+ 2.4 (shared libraries)
p libgtkmm-2.4-dev - C++ wrappers for GTK+ 2.4 (development files)
p libgtkmm-2.4-doc - C++ wrappers for GTK+ 2.4 (documentation)
p libgtkmm-dev - C++ wrapper for GTK+ 1.2 (development files)
p libgtkmm-doc - C++ wrapper for GTK+ 1.2 (documentation)
v libgtkmm1.2 -
c libgtkmm1.2-0 - C++ wrappers for GTK+ 1.2 (shared libraries)
v libgtkmm1.3-dev -
v libgtkmm1.3-doc -
v libgtkmm2.0-1 -
i A libgtkmm2.0-1c102 - C++ wrappers for GTK+ 2.0 (shared libraries)
p libgtkmm2.0-dev - C++ wrappers for GTK+ 2.0 (development files)
p libgtkmm2.0-doc - C++ wrappers for GTK+ 2.0 (documentation)
v libgtkmmext-dev -
p libgtkmmext0 - library of useful new C++ and C widgets for gt
p libgtkmmext0-dev - libgtkmmext development files

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.
