I'm working around this issue by using a struct of size 8
A struct of size 8 does not behave the same as an integer type.
For compiling sqlite.c, I'm using a 64-bit integer type. I'm only
using the struct for compiling C++ modules that include sqlite.h.
This means that you cannot link the C and C++ code together, because
they use different types.
Good point. I was planning to cross fingers that an 8-byte POD struct
will align nicely with a 64-bit integer. (Would need to take care about
endianness, too.) I'm open to alternatives.
On the C++ side I'll find a suitable way to handle the data.
How exactly do you get the C++ compiler to handle an 8-byte struct the
same as a 64-bit integer (a type which it supposedly does not have)?
I'd use a multiprecision C++ class. My code uses 64-bit integers only
for reading and writing column data.
