= 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.
