RE: [sqlite] sqlite and borland c++ builder
Hi John,
Thank's for responding. Someone actually very generously emailed me an
attachment a bit earlier that seemed to work, now I am having other problems
which I think are unrelated. To be honest I am beginning to think it is
this version of c++ builder that is just extremely buggy.
Thanks,

RE: [sqlite] sqlite and borland c++ builder
Hi Ulrik,
Sqlite3.h already seems to have the #ifdef extern "C" , etc as Joe Wilson
mentioned, and I try just #include and I get that error I
mentioned in my previous post about "[C++ Error] sqlite3.h(1778): E2232
Constant member 'sqlite3_index_info::nConstraint' in class without
constructors"
I searched on google about this and someone removed the const's from the
structs related to sqlite3_index_info and then it compiles with the header
but then I hit yet another error which states: "Unresolved external
'_sqlite3_open' referenced from MAIN.OBJ"
I think others have posted receiving that error but I'm not sure there were
any resolutions..Any ideas on this note?
Thanks

Hi Jonathan,
I don't use Borland C, so I can' help you with the specifics of that
compiler.
But no, you don't necessarily get an executable just by compiling with a
C compiler. You should be able to compile SQLite with a C compiler,
and in the process obtain one or more .o files. (Perhaps they are
called .obj in Borland C.)
With the GNU C compiler (and many other compilers), the switch to create
a .o file instead of an executable is -c. Maybe this translates to /c
on Borland C, but you'd have to consult your Borland C manual for that.
These .o/.obj files can be linked into your C++ program. If you follow
Joe Wilson's advice and just #include from within C++, it
should work.
That is exactly what the 'extern "C"' clause is for in C++: It tells the
C++ compiler that the functions within the 'extern "C" { ... }' block
were compiled with a compiler that emits code with C calling
conventions. This enables calling C code from within C++. As you
probably know, calling conventions have to do with, among other things,
the way function parameters are put on the stack, and the way any return
value is returned.

#ifdef __cplusplus

... contents of sqlite3.c ...

I wrote too quickly - sqlite3.h correctly uses __cplusplus for extern "C".
But the almalgomated sqlite3.c cannot be compiled from a C++ compiler
for the reasons described below.

RE: [sqlite] sqlite and borland c++ builder
I really appreciate your response. What do you suggest I do? Is there
something else I need to include aside from sqlite3.lib? I am willing to
try anything.
Thanks a lot

It appears it is trying to compile the sqlite header file as if it were C++.
Lemme guess - you're using the almalgomated sqlite3.c from 3.3.17, right?
from the generated sqlite3.c:
/*
** Make sure we can call this stuff from C++.
*/
#if 0
extern "C" {
#endif
See the #if 0? That's the problem. It should be:
#if __cplusplus
SQLite 3.3.17 has a bug in sqlite3.c generation.
To work around this issue, do this:
extern "C" {
#include "sqlite3.h"
}

Re: [sqlite] sqlite with borland c builder
Make sure you compile the dll (if you are compiling a dll, offcourse) with the C calling convention. I'm not sure now, but if I remember correctly that is not the default for the Borland compiler. Other cause could be not linking with the import library, but that is basic. Just my two cents. I don't work with a borland compiler anymore.
