Task Build Notes
----------------

Task 1.9 has dependencies that are detected by the configure program in almost
all cases, but there are situations and operating systems that mean you will
need to offer configure a little help.

If task will not build on your system, first take a look at the Operating System
notes below.  If this doesn't help, then go to the Troubleshooting section,
which includes instructions on how to contact us for help.



Operating System Notes
----------------------

Cygwin 1.7
  Building task on Cygwin 1.7 requires a configure option:

    ./configure --with-ncurses-inc=/usr/include/ncurses

  This is because the ncurses include files are in a different location to
  Cygwin 1.5.


Haiku Alpha/R1
  Task must be built with gcc version 4.x, so make sure you run:

    $ setgcc gcc4

  To switch from gcc 2.95 to gcc 4.x.



Troubleshooting
---------------

In most cases, it is sufficient to run the configure program like this:

  $ ./configure

Configure will run and locate all the necessary pieces for the build, and create
a Makefile.  There may be errors and warnings when running configure, or there
may be compiler errors and warnings when running 'make'.  Sometimes you will run
configure with no reported problems, and the build will fail later.  This is
almost always because configure is mistaken about some assumption.

The configure program can accept several options that help with its ability to
locate and use the ncurses library.  They are:

  --with-ncurses

    This option tells configure that no matter what it thinks, ncurses is
    definitely on this system and should be enabled.  If needed, this option
    probable needs to be accompanied by the next two options.

  --with-ncurses-inc=/usr/include

    If configure cannot find ncurses header files, this option will tell it
    exactly where to look.  The path specified in this example is the default,
    so that probably won't help you.  The path should be the directory in which
    the file 'ncurses.h' resides.  Here are some possible values to try:

      /usr/include                    (the default shown above)
      /usr/include/ncurses
      /usr/local/include
      /usr/local/include/ncurses

    This should cover most systems, but new variations keeps cropping up.

  --with-ncurses-lib=/usr/lib

    If configure cannot find the ncurses library, this option will tell it
    exactly where to look.  The path specified in this example is the default,
    so that probably won't help you.  The path should be the directory in which
    the file 'libncurses.a' (or your system's equivalent) resides.  Here are
    some possible values to try:

      /usr/lib
      /usr/local/lib

    This should cover most systems, but new variations keeps cropping up.

  --without-ncurses

    This disables ncurses support in task, and should really be used as a last
    resort.  We know of no systems where this is needed.

If trying these options does not succeed, please send the contents of the
'config.log' files to support@taskwarrior.org, or post a message in the support
forums at taskwarrior.org along with the information.

If configure runs, but task does not build, when ideally you would send both the
contents of config.log, and a transcript from the build, which is not written to
a file, and must be captured from the terminal.
