Dear all,
Last July, I posted a message on this list regarding adding CMake
support, and created this ticket:
https://issues.apache.org/jira/browse/XERCESC-2077
The patch is ready for integration, having been tested on a multitude of
platforms, including FreeBSD, Linux, MacOS X and Windows with multiple
configuration and compiler combinations. Following the last comments in
the above ticket, I'm writing here to propose and ask for comments on
the next steps for integrating it.
There are two choices for merging it:
- to the 3.1 branch
- to the trunk, for releasing as 3.2
Since the proposed changes don't touch any of the existing build
systems, merging onto the 3.1 branch would be safe, but since it's a
fairly large change it would be understandable to leave this for a new
minor release. Is there any particular preference?
A follow-on question would be the continued support for other build
systems following the merging of the patch. The use of CMake will allow
for the removal of the many version-specific Visual Studio solution and
project files, since CMake can support all the same Visual Studio
versions, and with a great deal more flexibility for e.g. ICU support
and other configure-time options. The same could also be said of the
Autoconf support, since CMake can also generate Unix Makefiles. For
maintenance reasons, I'd like to propose removing all the Visual Studio
files; this was one of the primary reasons for developing the CMake
support in the first place. This would make sense to do on the
trunk/3.2 branch, since we wouldn't want to remove existing
functionality on the 3.1 branch.
Removing the Autoconf support would also be a possibility if there was
consensus to do so. The CMake support certainly implements all the
Autoconf features--it reproduces every single feature test and option
exactly. But the maintenance cost is vastly less than the Visual Studio
support, so retaining both Autoconf and CMake support is certainly possible.
Integration test results for a range of platforms is also here:
https://ci.openmicroscopy.org/view/Third-Party/ (all the XERCESC- jobs).
Additionally, if anyone wanted to review and test the patch, it's
attached to the above ticket and also available here:

Kind regards,
Roger Leigh
