Building old versions

Introduction

It can be useful to build an old version of Apache OpenOffice, for example in order to regression test a bug in the latest version.

However, over time, patches get committed to allow building on newer build environments (newer operating systems, newer settings, newer libraries (as old ones may be unavailable), etc). Thus old AOO versions may be unable to build with the latest operating systems and latest libraries. Instead of the long and difficult process of setting up an old build environment, we can backport certain patches that added the features we need, and still build older versions on newer build environments.

How to

From the base directory of trunk/, for each patch that is newer than the version you are building and that you need, run this in REVERSE ORDER of the order given below, (ie. bottom to top, which is oldest to newest):

git show <commit> | patch -p1
(eg. git show 9fbe0120861764e7e644476857de32c44186c400 | patch -p1)

If a patch doesn't apply, you have to make the equivalent code changes yourself.

Other

Prefer internal dependencies, as transitive dependencies on system dependencies are difficult to get working, eg. old serf's use of new system OpenSSL would need serf patched.

Some old versions put the include path for system headers ahead of the include path to project headers, which can break the build if a dependency is installed system-wide but we want to use a local copy. For example, vcl wants boost, but if you have system boost installed yet are using internal boost, it will try including the system boost headers and break. The easiest way to fix this is to uninstall or hide/rename the system dependency so it's hidden to the build, forcing only the internal version to be used.
