Hello Frediano,

Yes please send us the binaries, but please give a clear description
(step by step) to execute the test.

I known nothing about the regression tests (what is "common.[ch]" or
the PWD file)?

Do we have to compile the test?

Will you provide us only binaries?

Should we compile the whole HEAD sources on Win64 and run our tests?

Cheers,
Seb

Send us a test program and we'll check if you want.

I wrote a small test at
http://freetds.cvs.sourceforge.net/freetds/freetds/src/odbc/unittests/te
st64.c?view=log. This source is a unittest for freetds so it require
common.c and common.h to compile and PWD file to configure.

It works under win32 and linux x86_64 (I used unixODBC and ubuntu 7.10).

Yesterday I managed to get win64 cross compile (thanks to mingw-w64
project!). Can I send you compiled freetds for win64 to test?

Yes, this is what I fixed.

See http://support.microsoft.com/?scid=kb%3Ben-us%3B298678&x=14&y=7

Also from our configure.ac

# check is SQLParamOptions accept SQLULEN
AC_TRY_COMPILE([#if defined(_WIN32) ||
defined(WIN32) ||
defined(__MINGW32__)
#include <windows.h>
#endif
#include <sql.h>
#include <sqlext.h>

SQLRETURN SQL_API SQLParamOptions(SQLHSTMT hstmt,
SQLULEN crow, SQLULEN *pirow) {
return SQL_SUCCESS;
}], [return 0],
AC_DEFINE(TDS_SQLPARAMOPTIONS_SQLLEN, 1,
[Define to 1 if
SQLParamOptions accept SQLULEN as arguments]))
)

but in odbc.c

SQLRETURN ODBC_API
SQLParamOptions(SQLHSTMT hstmt, SQLULEN crow, SQLULEN FAR * pirow)
{
SQLRETURN res;

This is a problem in MS specifications... pirow should correspond to
SQL_ATTR_PARAMS_PROCESSED_PTR which is not 64-bit according
which above
link. Also SQL_ATTR_PARAMS_PROCESSED_PTR (see SQLSetStmtAttr
documentation) maps to IPD SQL_DESC_ROWS_PROCESSED_PTR which is not
documented as 64-bit. However SQL_ATTR_ROWS_FETCHED_PTR
which correspond
to IRD SQL_DESC_ROWS_PROCESSED_PTR is documented as 64-bit. So is
SQL_DESC_ROWS_PROCESSED_PTR 32 or 64 bit?? Is it 64-bit
only for IRD??
Does pirow maps really to SQL_ATTR_PARAMS_PROCESSED_PTR
that maps on IPD
SQL_DESC_ROWS_PROCESSED_PTR?

Someone have a 64-bit windows machine to execute some
test?? I can pass
some source test in order to test all that stuff... just to
know how MS
implemented its specifications... Is MingW available for 64-bit??
