After being in Development Hell for...I forgot how many months, Wesnoth-TC, the advanced Team-Colorizer version 1.5.0 is finished and released.
This version introduces a few changes in the output files' naming scheme, and adds support for palette switches a la ~PAL() image function from Wesnoth's engine (which I implemented, by the way). The old Makefile is gone and there's a normal autotools build system in place, which seems to work well on Linux systems, as well as Mac OS X and even Mingw32-based cross compiling environments!
Thanks to this improvement and a small help from loonycyborg, Wesnoth-TC also has a experimental “official” Win32 build this time, which I have successfully tested on Windows XP SP3, and Debian Squeeze using WINE. It was cross-compiled using the Mingw32 environment packages from Debian. There are no important functionality differences between the Win32 build and normal Unix-based builds. It remains a command-line application as it's supposed to be.
- Source code: wesnoth-tc-1.5.0.tar.bz2 (149.7 KiB)
- Windows (Win32) binary: wesnoth-tc-1.5.0-win32.zip (373.3 KiB)
In an ideal world, the availability of a CLI Win32 binary would raise interest on this tool and someone would volunteer for working with me on a GUI front-end. That's very unlikely to happen in the real world, so I'm researching Qt4 and messing around with some ideas for a cross-platform front-end based on penguin's Mac OS X applet.
Both distributions come with a README file, and the source code distro includes a INSTALL file with detailed instructions on configuring, compiling and installing wesnoth-tc. The Win32 binary distribution doesn't require any installation besides unpacking it into an appropriate directory — which you may optionally add to PATH.
EDIT: some people may have problems compiling under certain platforms or configurations because the configure script in this version enables strict mode by default, treating compiler warnings as errors. To solve this, pass the
--disable-strict option to
configure. Git master already solves this problem, plus a particular warning reported on Ubuntu 9.10.
Behind the scenes
As I mentioned before, I tried using gd for PNG manipulation but ultimately discovered that its limitations weren't nice for wesnoth-tc's particular case. I rewrote the PNG reading and writing code again afterwards, using the SDL_image library as a model instead.
The Win32 build doesn't have support for libpng exception handling (via
setjmp) because the compiler complains about it for some reason:
warning: variable ‘height’ might be clobbered by ‘longjmp’ or ‘vfork’
This shouldn't be a big deal since libpng won't complain unless someone feeds a corrupted or invalid PNG file to it. (EDIT: figured out the cause with some help, but haven't fixed it in Git master yet.) The other functionality change is the lack of support for checking file access permissions considering effective user and group ids, etc.
Supposedly, this release should work properly on PowerPC and other big-endian platforms. However, I don't have such a machine and therefore can't test.
