FTBFS on Ubuntu

[Guillaume Martres]

Extreme Tux Racer doesn't build on Ubuntu(confirmed on 7.10 and 8.04).
The error is here:
"./etracer.h:118:17: error: tcl.h: No such file or directory"
I've made a patch for the Ubuntu package which fix the location of the tcl.h file.

AFAIK, this was changed intentionally - please see http://extremetuxracer.svn.sourceforge.net/viewvc/extremetuxracer/trunk/extreme-tuxracer/src/etracer.h?view=log
Additionaly, in a Wiki article concerning compiling it is stated that one should use "./configure --with-tcl-inc=/usr/include/tcl8.4".

I think the patch is a good fix, because ideally a user would not have to specify arguments to configure to get it to work.
However, we need to check that it doesn't break things on other distros or OSes.

[Guillaume Martres (smarter)]

@Pawel: thanks for the tip, this option is not documented anywhere, I think it should be in the README or INSTALL files, and it should have sane defaults(does anyone know of a system where tcl.h is in /usr/include?) or the configure could autodetect it.

[Paweł Drewniak (woody)]

I've done a little investigation and it seems that:

/usr/include/ is commonly used in RPM-based distros (Fedore, SuSE, Mandriva)
/usr/include/tcl8.4 is used in DEB-based ones (Debian, .Ubuntu)

Furthermore, it turned out that we had a bug in configure.ac that prevented correct inclusion of tcl.h
It is now fixed in SVN.
