The Pro*C precompiler must parse all the C code, otherwise how can it recognise C variables to use as host variables? Unless it understands C++ code as well (which it doesn't) it will get confused.

Pro*C 2.1 can be used with C++, but it doesn't support it. There is a new precompiler option parse=no which disables the C parsing. This effectively goes back to v 1.6 where a declare section is required, so C++ 'support' is added by removing C support!

There is an Oracle support bulletin which discusses this. It is vague about future plans, but it implies that C++ support may not appear until OO support appears in Oracle8.
