How to get and install Civworld, http://www.freeciv.org/civworld/ Civworld must be compiled from source, in a Unix-like OS environment such as Solaris, Linux, FreeBSD, MS Windows with Cygwin, etc. It is a GUI program, requiring a running X server and the GTK+ library. The latest Civworld distribution is based on the Freeciv source tree as of June 9th, 2002. This means its maps are compatible with at least some Freeciv beta versions, 1.12.2, 1.12.4 and/or 1.12.6. The file civworld-1.13.0.tar.bz2 contains the whole civworld source tree. One it is made available, fetch it, and bunzip2 -c civworld-1.13.0.tar.bz2 | tar xvf - cd civworld-1.13.0 ./configure --prefix=$HOME/civworld-1.13.0 --disable-cvs-deps --disable-nls make mkdir $HOME/civworld-1.13.0 make install Try ./configure --help for alternative options. Note that --with-xaw doesn't work - you do need GTK+, version 1.x. However, civworld-1.13.0.tar.bz2 is not yet available. If you don't want to wait, fetch the patch file in this directory, civworld-1.13.0.diff-against-freeciv.bz2 and apply it against your 1.13.0 Freeciv source tree, as follows: # assuming the unpacked source tree is in a directory called freeciv/ cd freeciv bunzip2 -c ../civworld-1.13.0.diff-against-freeciv.bz2 | patch -p1 You do not get a ./configure in this case; run autogen.sh to create and run it, e.g. mkdir $HOME/civworld-1.13.0 ./autogen.sh --prefix=$HOME/civworld-1.13.0 --disable-cvs-deps --disable-nls make make install If all went well, you can now start civworld: $HOME/civworld-1.13.0/bin/civworld & Of course you can install it somewhere else if you want. Enjoy!
