1. Get a C++ compiler. The C++ source files use a suffix of `.cc', so
|
|
your C++ compiler must be able to handle this. If you don't already
|
|
have a C++ compiler, I suggest gcc 2.5.8 or later (gcc version 2
|
|
includes GNU C++ as well as GNU C). From gcc 2.5, it is no longer
|
|
necessary to install libg++: the C++ header files needed by groff are
|
|
created by the gcc installation process.
|
|
|
|
2. In the directory that this file is in, type `./configure'. If
|
|
you're using `csh' on an old version of System V, you might need to
|
|
type `sh configure' instead to prevent `csh' from trying to execute
|
|
`configure' itself.
|
|
|
|
The `configure' shell script attempts to guess correct values for
|
|
various system-dependent variables used during compilation, and
|
|
creates the Makefile. It also creates a file `config.status' that you
|
|
can run in the future to recreate the current configuration.
|
|
|
|
Running `configure' takes a minute or two. While it is running, it
|
|
prints some messages that tell what it is doing. It also performs
|
|
some checks on your C++ compiler. If these checks fail, it will print
|
|
a message and exit. In this case, you should correct the problems
|
|
with your C++ compiler and then rerun configure.
|
|
|
|
To compile the package in a different directory from the one
|
|
containing the source code, you must use GNU make (or a version of
|
|
make that supports VPATH in the same way as GNU make). `cd' to the
|
|
directory where you want the object files and executables to go and
|
|
run `configure'. `configure' automatically checks for the source code
|
|
in the directory that `configure' is in and in `..'. If for some
|
|
reason `configure' is not in the source code directory that you are
|
|
configuring, then it will report that it can't find the source code.
|
|
In that case, run `configure' with the option `--srcdir=DIR', where
|
|
DIR is the directory that contains the source code.
|
|
|
|
By default, `make install' will install the package's files in
|
|
/usr/local/bin, /usr/local/lib/groff, and /usr/local/man. You can
|
|
specify an installation prefix other than /usr/local by giving
|
|
`configure' the option `--prefix=PATH'. Alternately, you can do so by
|
|
changing the `prefix' variable in the Makefile that `configure'
|
|
creates.
|
|
|
|
You can specify separate installation prefixes for
|
|
architecture-specific files and architecture-independent files. If
|
|
you give `configure' the option `--exec_prefix=PATH', the package will
|
|
use PATH as the prefix for installing programs and libraries. Data
|
|
files and documentation will still use the regular prefix. Normally,
|
|
all files are installed using the regular prefix.
|
|
|
|
You can tell `configure' to figure out the configuration for your
|
|
system, and record it in `config.status', without actually configuring
|
|
the package (creating `Makefile's and perhaps a configuration header
|
|
file). To do this, give `configure' the `--no-create' option. Later,
|
|
you can run `./config.status' to actually configure the package. This
|
|
option is useful mainly in `Makefile' rules for updating `config.status'
|
|
and `Makefile'. You can also give `config.status' the `--recheck'
|
|
option, which makes it re-run `configure' with the same arguments you
|
|
used before. This is useful if you change `configure'.
|
|
|
|
`configure' ignores any other arguments that you give it.
|
|
|
|
If your system requires unusual options for compilation or linking
|
|
that `configure' doesn't know about, you can give `configure' initial
|
|
values for some variables by setting them in the environment. In
|
|
Bourne-compatible shells, you can do that on the command line like
|
|
this:
|
|
CC='gcc -traditional' DEFS=-D_POSIX_SOURCE ./configure
|
|
|
|
The `make' variables that you might want to override with environment
|
|
variables when running `configure' are:
|
|
|
|
(For these variables, any value given in the environment overrides the
|
|
value that `configure' would choose:)
|
|
CC C compiler program.
|
|
Default is `cc', or `gcc' if `gcc' is in your PATH.
|
|
CCC C++ compiler program (for .cc files).
|
|
By default, configure will look for gcc version 2, g++,
|
|
and then CC.
|
|
INSTALL Program to use to install files.
|
|
Default is `install' if you have it, `cp' otherwise.
|
|
PAGE This should be `A4' if your PostScript printer uses
|
|
A4 paper and `letter' if your printer uses 8.5x11in
|
|
paper.
|
|
|
|
(For these variables, any value given in the environment is added to
|
|
the value that `configure' chooses:)
|
|
DEFS Configuration options, in the form `-Dfoo -Dbar ...'
|
|
LIBS Libraries to link with, in the form `-lfoo -lbar ...'
|
|
CCLIBS Libraries to link C++ programs with, in the same form.
|
|
|
|
If you have a library that provides a faster malloc than your system's
|
|
usual malloc, it is good idea to include it in LIBS. For example,
|
|
using the malloc that comes with GNU Emacs version 18 can give a
|
|
worthwhile (and sometimes spectacular) performance improvement.
|
|
|
|
If you need to do unusual things to compile the package, we encourage
|
|
you to figure out how `configure' could check whether to do them, and
|
|
mail diffs or instructions to the address given in the README so we
|
|
can include them in the next release.
|
|
|
|
3. Have a look at the generated Makefile. The options you are most
|
|
likely to want to change are near the beginning. Make sure that the
|
|
definition of PAGE is correct.
|
|
|
|
4. Type `make'.
|
|
|
|
5. Use the test-groff script to try groff out on one of the man pages.
|
|
(Use the .n files not the .man files.) The test-groff script sets up
|
|
environment variables to allow groff to run without being installed.
|
|
The current directory must be the build directory when the script is
|
|
run. For example, you could do
|
|
|
|
./test-groff -man -Tascii groff/groff.n | less
|
|
|
|
6. If you want to install gxditview (an X11 previewer), follow the
|
|
instructions in the INSTALL file in the xditview directory.
|
|
|
|
7. Type `make install' to install groff.
|
|
|
|
8. Try the installed version of groff on one of the man pages.
|
|
|
|
If you have problems, read the PROBLEMS file. If this doesn't help
|
|
send a bug report using the form in the file BUG-REPORT.
