Splint - Source Code Installation

## Source Code Installation

Splint should compile effortlessly on standard Unix systems, and with a bit of effort on non-Unix platforms. If you produce a port for a non-Unix platform, please let splint@cs.virginia.edu know.

To build Splint you need:

- a (hopefully ANSI-conforming) C compiler. GNU `gcc` is recommended, but most modern C compilers should work.
- `make`, the GNU make utility. If you don't have `make` installed on your system, download it from `ftp.gnu.org`.
- standard Unix tools: `gzip`, `tar`

Instructions:

1. Download http://www.splint.org/downloads/splint-3.1.1.tgz. (the latest stable release).

   Copy this package to the directory where you want to build Spint. When the tar file is extracted, it will create a splint-3.1.1 subdirectory.

2. `tar xzf splint-3.1.1.src.tgz` (extract files from the archive)

3. `cd splint-3.1.1` (enter the extracted directory)

4. `configure`

   > This will create a Makefile with settings for your system. Use `configure --prefix=directory` if you want to install Splint in prefix directory directory.

5. `make`

   > GNU's make utility is required; it may be named `gmake` or `gnumake` on your system. It is best to do this in an emacs shell or a buffered terminal, so you can scroll through the output.

   > This builds Splint. While it is building, subscribe to the splint-announce mailing list by visiting http://www.splint.org/lists.html

   > If the build was successful, it then runs the test suite. You should see:

   > >     Testing splint 3.1.1...

   > >     Version Info:
   > >     Splint 3.1.1 --- 11 Feb 2002
   > >     Maintainer: splint-bug@splint.org

   > >     ... (about 100 lines of test output elided)

   > >     Checking manual...
   > >     Checking tests2.2...
   > >     Checking tests2.4...
   > >     Checking tests2.5...
   > >     Checking db1...
   > >     Checking db2...
   > >     Checking db3...

   > Examine the test output. If there are errors, send a bug report to splint-bug@cs.virginia.edu.

   > Note: If possible do not built splint in a directory under /usr/. If the test suite is run in a directory under /usr/ for example /usr/src/, it will report errors even if Splint was built correctly.

The remaining steps are only necessary if you want to install the Splint binary and libraries in a different directory (set when you ran configure).

> 6. `make install`
> 7. Set environment variables:

>    > `LARCH_PATH` - path to search for splint libraries and initializations files. If you are using the standard directories, this should be `.:base-directory/splint-3.1.1/lib`.

>    > `LCLIMPORTDIR` - directory containing lcl imports files. If you are using the standard directories, this is `base-directory/splint-3.1.1/imports`.

>    Put the commands to set these variables (the actual commands will depend on the shell you are using) in one of your initialization dotfiles (usually `~/.environment`).

>    Set up your `PATH` to include the directory containing `splint-3.1.1/bin/splint`, or move the binary to a directory on your command path.
