I am getting the following compiler errors, and I was wondering if there =
was a way to get around the unsupported 'long long.'

The error is correct: "long long" is an extension to the langauge. It's
no doubt arising because you're turning on the pedantic error flag,
which is being extra strict about the language it will support.

If you don't need this feature, you can #define NO_LONG_LONGS, but this
will only affect MySQL++, not the C API. Also, there were problems with
this mode until very recently in the MySQL++ v2.0 development; I'm not
even sure if the fixes are in beta2. You may have to use the repository
version.

Personally, I'd reconsider using -pedantic-errors for all compiles.
Turning such warning flags on from time to time can be helpful in
finding problems, but a lot of the "errors" compilers complain about in
this sort of mode are just plain silly.

Using the #define NO_LONG_LONGS got rid of that problem, but how can I =
get around the problem of all of these redefinitions which result from =
this change. =20

Those are the known problems I spoke of. Use the repository version of
MySQL++. Or, give up on your pedantic error flag!

I gave up on the pedantic error flag, and I was still getting those =
errors. I will try the repository version. Thank you for your =
assistance.
