Requirements
------------
You will need a C99 compiler and a C library compatible with POSIX.
(gcc 3.3.6 or newer is recommended).
I use gcc 6.1.0 and 3.3.6, but the code should compile with any standards
compliant compiler.
Gcc is available at http://gcc.gnu.org
Lzip is available at http://www.nongnu.org/lzip/lzip.html
Procedure
---------
1. Unpack the archive if you have not done so already:
tar -xf ed[version].tar.lz
or
lzip -cd ed[version].tar.lz | tar -xf -
This creates the directory ./ed[version] containing the source code
extracted from the archive.
2. Change to ed directory and run configure.
(Try 'configure --help' for usage instructions).
cd ed[version]
./configure
If you choose a C standard, enable the POSIX features explicitly:
./configure CFLAGS+='--std=c99 -D_POSIX_C_SOURCE=2'
3. Run make.
make
4. Optionally, type 'make check' to run the tests that come with ed.
5. Type 'make install' to install the program and any data files and
documentation. You need root privileges to install into a prefix owned
by root.
Or type 'make install-compress', which additionally compresses the
info manual and the man page after installation.
(Installing compressed docs may become the default in the future).
You can install only the program, the info manual, or the man page by
typing 'make install-bin', 'make install-info', or 'make install-man'
respectively.
Another way
-----------
You can also compile ed into a separate directory.
To do this, you must use a version of 'make' that supports the variable
'VPATH', such as GNU 'make'. 'cd' to the directory where you want the
object files and executables to go and run the 'configure' script.
'configure' automatically checks for the source code in '.', in '..', and
in the directory that 'configure' is in.
'configure' recognizes the option '--srcdir=DIR' to control where to look
for the source code. Usually 'configure' can determine that directory
automatically.
After running 'configure', you can run 'make' and 'make install' as
explained above.
