ODBC Driver

64 bit ODBC error connecting from OpenOffice (isql is ok)

Environment: Ubuntu Linux 64 bit (both on 8.10 and 9.04)

 Description  « Hide
I setup an ODBC connection to fb database and via the unixodbc isql tool I can connect correctly and do queries.
When I try to connect via OpenOffice (both version 2 and 3), after I log on at the password window, I get the error: "[unixODBC][ODBC Firebird Driver]Invalid clumplet buffer structure: buffer end before end of clumplet - clumplet too long"; Via the unixodbc log I can't see anything logged (it is enabled and woks, when I get connected via isql). OpenOffice ODBC works well with other drivers for other databases (ie mysql).
Thanks for any interest on my problem.

I report the same issue on opensuse11.1 64 with openoffice 3.1.1

Still same error....even with Ubuntu 10.04; I would like to receive some updates but this thread seems dead...after all it's an issue with openoffice, a diffused suite....

I am find the same problem in Asterisk PBX RealTime application under 64 bit RH Linux. "[unixODBC][ODBC Firebird Driver]Invalid clumplet buffer structure: buffer end before end of clumplet - clumplet too long". Opening has shown presence to an error in "isc_dpb_connect_timeout" parameter transmission from ODBC Firebird driver to the Firebird client. The matter is that in the ODBC Firebird Driver src-file "../IscDbc/Attachment.ccp" starting at the line 218 (cvs source code from 11 Jun 2010) there is code:
const char *timeout = properties->findValue ("timeout", NULL);

if (timeout && *timeout)
connectionTimeout = atoi(timeout);

*p++ = isc_dpb_connect_timeout;
*p++ = sizeof (long);
*p++ = (char)connectionTimeout;
*p++ = (char)(connectionTimeout >> 8);
*p++ = (char)(connectionTimeout >> 16);
*p++ = (char)(connectionTimeout >> 24);
In 32 bit Systems sizeof (long)==4, but 64 bit System sizeof (long)==8 !!!
I pay attention that in "p" place 4 bytes only. And Firebird/Interbase client wait 0..4 bytes using method:
SLONG ClumpletReader::getInt() const
const UCHAR* ptr = getBytes();
size_t length = getClumpLength();

if (length > 4) {
invalid_structure("length of integer exceeds 4 bytes");
return 0;

// This code is taken from gds__vax_integer
SLONG value = 0;
int shift = 0;
while (length > 0) {
value += ((SLONG) *ptr++) << shift;
shift += 8;

return value;
For this reason to FIX this truble in the "../IscDbc/Attachment.ccp" at line 225:
*p++ = sizeof (long);
..] need replace on:
*p++ = 4;
That code realy do work both on 32, and on 64 bit Systems.
The reason on which not in all applications the given error that attribute SQL_ATTR_LOGIN_TIMEOUT install not all appears. The Asterisk PBX, OpenOffice 3.1.1 do it. I researched their source codes on this subject.

Ivan, thank you for the post...I'm sorry to bother you. I've been trying for a while to compile from source but I'm unable (I have the gcc 4.4.3 of Ubuntu 10.04 + unixodbc-dev installed); when I go in /builds/Gcc.lin/ and type make -f makefile.linux I get a lot of errors from the original source packet too.
Can you pls help me on building it or tell me where can I find a compiled one ?

Hey, Federico. ODBC driver for Firebird is the bridge between host ODBC driver (unixodbc in this time) and the Firebird/Interbase client library. To compile the module you need to install the firebird-devel.x86_64 package on your x86-64 Linux System also. Still it is necessary to be convinced that the firebird-libfbclient.x86_64 package is installed if you did not have placed Firebird server there. It is not necessary for compile but needs to work.

I attach myself compiled driver. It is to work in x86_64 Linux System under kernel.

Ivan, thank you for the attachment, I tried it, it works ok with unixodbc, but when I connect via OpenOffice I get no errors but the application hangs and after some seconds the system starts using intensively the disk (even if I don't see swapfile grow) until it hangs. I use Ubuntu 10.04 with kernel 2.6.32-22-generic, it shouldn't happen since it's always 2.6....any idea ? Thank you in advance.

Federico, test your SQL script without ODBC or try write more simpler. You may attach backup and I try it in my system. I think ODBC and Ubuntu do not matter
