[Plplot-general] build errors and cmap0

Hello,

I am trying to build plplot on Windows XP and although I was able to get it
going I have some errors that I cannot figure.

I use a batch file to build the install (using instruction on the wiki
page).  I couldnt figure how to get (or build) cairo and pkg-config (and
glib?).  But when trying to install GTK+ it just seemed to work.  Obv. the
PKG_CONFIG_PATH is not being set appropriately.

The contents of my batch file are:
cd buildmingw
set PATH=%PATH%;C:\gtk\bin
cmake -G "MinGW Makefiles" -DBUILD_TEST=ON -DCMAKE_INSTALL_PREFIX=install ..
set PATH=%PATH%;C:\plplot-5.9.5\buildmingw\dll
mingw32-make
mingw32-make install

(I chose to build examples as I couldnt do it otherwise but thats for
later).

when running "mingw32-make" command, the following error gets generated and
when I re-run it, it just skips over and exits successfully.

*********

Following this, the "mingw32-make install" gets completed without issues.
However, when running an example from
C:\plplot-5.9.5\buildmingw\examples\C++, I universally get the following
message (twice):

=====
*** PLPLOT WARNING ***
Unrecognized cmap0 format data line.  Line is #000000
=====

This leads to all the examples to have a white background.  I tried using
the command line option of -cmap0 filename and -bg color but without
success.

If someone can point out the source of this cmap0 warning and also, how to
definitively install the necessary packages cairo/pkg-config/glib that'd be
great.

Please let me know if you need more information.  (Note that the mingw
environment used was the one that came when installing Qt.)

Thank you.
