Build instructions

Building

Building this package from a distribution tarball should be as simple as running make. Install with "make install" as root.

You will need xmlto to build the derived forms of the documentation from the DocBook-XML sources. If you are going no modify the website, you will also need to have asciidoc and the ImageMagick convert(1) utility installed.

Testing

You can run "make check" after the library and utilities have been built to see a regression test of the codebase. No output (other than the test header lines) is good news.

Portability note

This codebase now assumes your compiler is C99-conformant. If it isn’t, the most likely trouble spot is "#include <stdint.h>"; your compiler may be looking for "inttypes.h" instead. By test, the code is backward-conformant to C89 except that it uses bool/true/false.

One (minimal but sufficient) concession to Windows portability has been make; inclusion of <unistd.h> is conditional on _WIN32 not being defined by the compiler (if it is <io.h> is included instead). Requests to go any further out of the way to accommodate Microsoft’s toolchains are unlikely be looked on favorably.

Release Procedure

  1. Check the SourceForge tracker for bugs and patches.

  2. Bump the version number in gif_lib.h. Do "make version" to confirm that it looks sane when extracted to the Makefile.

  3. Version-stamp the top entry in the NEWS file.

  4. If you are changing major versions, sync the XBS-SourceForge-Folder attribute in the control file.

  5. 'make dist' to make a tarball.

  6. Tag the release in the repo.

  7. Ship the release tarball.

The last three steps can be done with "make release" if you have shipper installed.
