Known issues
============

Fish is developed using GCC, with the goal of using only C89 language
features. Fish does, however use the *wprintf family of functions,
which are new to the C99 standrard. It is not unlikely that any given
release contains a few GCC:isms, but ICC 9.0.030 has been found to
produce working binaries. GCC 2.95.* won't compile fish, but GCC 3.2.3
is known to work. Patches to fix any remaining GNU:isms are welcome.

Older versions of Doxygen has bugs in the man-page generation which
cause the builtin help to render incorrectly. Doxygen 1.2.14 is known
to have this problem.


Prerequisites
=============

Fish requires the following programs and libraries to build:

 - Doxygen
 - Curses or Ncurses
 - GNU make
 - GCC

fish also relies on standard unix tools such as cat, cut, grep, sed,
whoami, bc and echo. Fish does not yet support cross-compilation,
separate build directories or any other fancy configure options.


Simple install procedure
========================

If you have downloaded the darcs repository of fish, you need to run
the autoconf command first. Then use the following commands to compile
fish:

 % ./configure
 % make                                   # Compile fish
 % make install                           # Install fish
 % echo /usr/local/bin/fish >>/etc/shells # Add fish to list of shells

If you wish to use fish as your default shell, use the following
command:

 % chsh -s /usr/local/bin/fish			 

chsh will prompt you for your password, and change your default shell.


Local install procedure
=======================

If you have downloaded the darcs repository of fish, you need to run
autoconf to generate the configure script.

To install fish in your own home directory (typically as non-root),
type:

 % ./configure --prefix=$HOME
 % make					# Compile fish
 % make install			# Install fish

You will not be able to use fish as the default shell unless you also
add the corresponding line to /etc/shells, which mostly defeats the
point of a local install. As a workaround, you can add fish as the
last command of the init files for your regular shell.
