[Pharo-project] Loading FFI into Pharo?
In the end I'm trying to get ODBC running Pharo 1.1. I checked the docs and this should work: ScriptLoader loadFFI. for loading the FFI stuff. If I try that I get the message that this selector is unkwown. What am I supposed to do to get it known? Regards Friedrich

I haven't had much trouble with it. You can look in the inbox for Migrate (for how I load it) and the DolphinCompatibility package for things that I have added to the ODBC support. ________________________________________ From: pharo-project-bounces@lists.gforge.inria.fr [pharo-project-bounces@lists.gforge.inria.fr] On Behalf Of Friedrich Dominicus [frido@q-software-solutions.de] Sent: Thursday, October 21, 2010 9:06 AM To: Pharo-project@lists.gforge.inria.fr Subject: Re: [Pharo-project] Loading FFI into Pharo?

Are there any usage examples for ODBC and Pharo or is it go out and find out yourself? And another maybe stupid question has anyone used it for accessing .mdb databases from MS-Access?

Ok i'm probabla currently a bit confused. AFAIKT the Pharo I've running here is 32-bit. My machine however is a 64-bit System, so to use the unixodbc I probably would need the 32-bit version of the unixodbc driver. Is that correct?
So do I have to build the unixodbc stuff myself? on a Debian 64-bit box? Regards Friedrich -- Q-Software Solutions GmbH; Sitz: Bruchsal; Registergericht: Mannheim Registriernummer: HRB232138; Geschaeftsfuehrer: Friedrich Dominicus

Yes. Exactly. To compile ODBC you may want to try something like we did in SqueakDBX: http://www.squeakdbx.org/SqueakDBX%20in%2064%20bits Or....check if there is a binary for 32 bits.

http://www.squeakdbx.org/SqueakDBX%20in%2064%20bits Thanks my confusion has not last that long. I just was puzzling why isql does connect but Pharo won't. Sure the reason is clear, but it has catched me. Fine, I'm trying to get unixodbc compiled an installed on my 64 bit box. I just wonder has anyone build a 64-bit Pharo?

More or less. Because you need: a 64 bits VM, and a 64 bits image as much as I understand. In addition, there are certain bugs in FFI about using it in 64 bits.

You don't need a 64 bit image. If you have a 64 bit operating system than you can only execute 64 bit executables. In linux there are 32 bit compatibility libraries. The offer a 32 bit interface and mediate this to 64 bit. So you can run a 32 bit vm with compat libraries or native 64 bit vm. The same goes for code that you want to link to the vm. It needs to fit. What the vm internally uses for its address space does not depend on this. I think that is confusing for a lot of people that you can have a 64 bit vm with a 32 bit image. But does anyone know what is the state of 64 bit vm executables? Norbert

Ok, but it means to use Pharo 32 -bit with unixodbc I better have the 32-bit files of unixodbc installed. I'm having that currently but, I still can not connect to Postgres. I guess I will have to delve into this quite a bit deeper.

Why not trying SqueakDBX or the native postgres driver ? I guess I will have to delve into
this quite a bit deeper.

Details here: http://bugs.squeak.org/view.php?id=7237 FFI can be made to work on 64-bits but it is difficult and complicated, so if you are just trying to get ODBC working you should stick with 32 bit binaries. Dave
