Looks like Perl redefined cbool from something sensible to this new flavor:
#define cBOOL(cbool) ((bool) (cbool)) Which causes all sorts of compiler complaints, as you have seen. I'm not sure what the proper solution is: some places like https://www.spinics.net/lists/linux-perf-users/msg27894.html seem to suggest that ignoring that warning is the way forward at this point. I think it was a poor decision to change cBOOL like that, but not sure if there is anything that can be done at the DBI level. As a first step, try taking -Wbad-function-cast out of $opts{DEFINE} in Makefile.PL and see if that at least gets it to compile. Cheers, Greg
