Hi Brian,
Regenerating mysql_filtered.h indeed works on Fedora 11 but you will break
compilation on other platforms (like CentOS or RHEL 5) because these have
different mysql.h header files. It looks like there was quite a big change
in the mysql.h header file.
What actually should be done is (at compilation/packaging time) use the
original mysql.h file from the OS and generate the swig stuff with SWIG.
This of course adds a dependency to SWIG which is now not there because the
swig files are already generated.
Regards
Wim
