Firebird IBPP use in non-unicode project

I posted this in a comment here, a long while ago. I forgot about it but yesterday someone posted in the same topic, and therefore I received an e-mail.

As my comment somehow isn't visible on the blog (maybe it was never moderated?) i'll post it here. I was using it in a non-unicode project myself, so I encountered the same problem. According to the mail I recvd this is what I wrote:

Nice fixes.

How I get the sourcecode to work in my unicode program however, without modifying the source is as follows.

Simply don't compile the file all_in_one.cpp (or all ibpp/core/*.cpp files individually) with the defines/"preprocessor definitions" _UNICODE and UNICODE enabled.

I didn't look at the Flamerobin source, but my guess is that they do the same.

IBPP in a Qt Creator project

Add the following in your .pro file:

DEFINES += IBPP_WINDOWS=value

LIBS += Advapi32.lib

the lib is for fixing

all_in_one.obj : error LNK2019: unresolved external symbol __imp__RegCloseKey@4 referenced in function "public: struct ibpp_internals::GDS * __thiscall ibpp_internals::GDS::Call(void)" (?Call@GDS@ibpp_internals@@QAEPAU12@XZ)
all_in_one.obj : error LNK2019: unresolved external symbol __imp__RegOpenKeyExA@20 referenced in function "public: struct ibpp_internals::GDS * __thiscall ibpp_internals::GDS::Call(void)" (?Call@GDS@ibpp_internals@@QAEPAU12@XZ)

Also added the following two #undefs to all_in_one.cpp.

#undef _UNICODE
#undef UNICODE
