Michele,

This is also a bug in the Borland/CodeGear C++ compiler (see 
http://qc.borland.com/wc/qcmain.aspx?d=32959 ). I am trying to get this 
report reopened, but in the meantime you will probably have to change 
the sqlite3.h file to add a conditional around the sqlite3_index_info 
definition, and remove the offending const qualifiers like this:


   #ifdef __BORLANDC__
   struct sqlite3_index_info {
 /* Inputs */
 int nConstraint; /* Number of entries in aConstraint */
 const struct sqlite3_index_constraint {
int iColumn;  /* Column on left-hand side of 
constraint */

unsigned char op; /* Constraint operator */
unsigned char usable; /* True if this constraint is usable */
int iTermOffset;  /* Used internally - xBestIndex 
should ignore */

 } *aConstraint;  /* Table of WHERE clause constraints */
 int nOrderBy;/* Number of terms in the ORDER BY clause */
 const struct sqlite3_index_orderby {
int iColumn;  /* Column number */
unsigned char desc;   /* True for DESC.  False for ASC. */
 } *aOrderBy; /* The ORDER BY clause */

 /* Outputs */
 struct sqlite3_index_constraint_usage {
   int argvIndex;   /* if >0, constraint is part of argv to 
xFilter */
   unsigned char omit;  /* Do not code a test for this 
constraint */

 } *aConstraintUsage;
 int idxNum;/* Number used to identify the index */
 char *idxStr;  /* String, possibly obtained from 
sqlite3_malloc */
 int needToFreeIdxStr;  /* Free idxStr using sqlite3_free() if 
true */

 int orderByConsumed;   /* True if output is already ordered */
 double estimatedCost;  /* Estimated cost of using this index */
   };
   #else
   struct sqlite3_index_info {
 /* Inputs */
 const int nConstraint; /* Number of entries in aConstraint */
 const struct sqlite3_index_constraint {
int iColumn;  /* Column on left-hand side of 
constraint */

unsigned char op; /* Constraint operator */
unsigned char usable; /* True if this constraint is usable */
int iTermOffset;  /* Used internally - xBestIndex 
should ignore */

 } *const aConstraint;  /* Table of WHERE clause constraints */
 const int nOrderBy;/* Number of terms in the ORDER BY 
clause */

 const struct sqlite3_index_orderby {
int iColumn;  /* Column number */
unsigned char desc;   /* True for DESC.  False for ASC. */
 } *const aOrderBy; /* The ORDER BY clause */

 /* Outputs */
 struct sqlite3_index_constraint_usage {
   int argvIndex;   /* if >0, constraint is part of argv to 
xFilter */
   unsigned char omit;  /* Do not code a test for this 
constraint */

 } *const aConstraintUsage;
 int idxNum;/* Number used to identify the index */
 char *idxStr;  /* String, possibly obtained from 
sqlite3_malloc */
 int needToFreeIdxStr;  /* Free idxStr using sqlite3_free() if 
true */

 int orderByConsumed;   /* True if output is already ordered */
 double estimatedCost;  /* Estimated cost of using this index */
   };
   #endif

Be advised, that after I do this I get a similar unresolved external 
error for _sqlite3_libversion. I'm trying to see what might be causing 
this, but the generated sqlite3.lib file looks OK on first inspection.

Maybe it is but it's hard to find the way to generate a suitable sqlite3.lib 
then.

It's a runtime error cos it is linked incorrectly!

Specify the sqlite.def file (which IIRC lists the undecorated aliases
of the sqlite functions) as an option to the command line of implib.

Michele,

This is a problem I discovered with Borland IMPLIB. The fix I found is 
described under ticket 1291 at 
http://www.sqlite.org/cvstrac/tktview?tn=1291


For some reason implib doesn't generate the correct  symbols when 
converting directly from the dll file.

It sounds like a load time error.  If that's the case, and it is the
Windows loader, then your import tool did not do translation
correctly: it's looking for the literal name "_sqlite3_open" in the
DLL exports.  Such a name does not exist.

The Microsoft import library format sets up name translations, where
the underscore is supplied for the usual linking mechanisms, but the
linker is also instructed to place the undecorated name in the
dependency table.  You want to have your tool do the same thing.
Failing that, look for a way to have the compiler not apply
decorations to dllimport function declarations.

One of those must be supported, since it would be required to use
Windows API functions (stdcall has a decoration format of its own).

Failing that, give up on the stock dll and build your own, or compile
sqlite directly into your project :)

Calling convention and name decoration. Your linker knows, that 
sqlite3_close() has to be called via cdecl
calling convention and does not look for sqlite_close(), but for 
_sqlite_close().


You have to tell your IDE, Linker - that it should not use naming 
decoration.

You are probably linking against exports with a leading underscore.
(The exports of sqlite3.dll don't have the _underscore). Does your dev
environment/linker have the option to disable this underscore
generation?

May depends on mscvrt dependancies?
