squeakopendbx, which VM?

On linux

I installed OpenDBX, checked it work to connect to my remote database

Then check for system awarness of it:

hilaire@tice:~/Documents/Projets/BaseRessources$ ldconfig -p | grep opendbx
    libopendbxplus.so.1 (libc6) => /usr/lib/libopendbxplus.so.1
    libopendbx.so.1 (libc6) => /usr/lib/libopendbx.so.1


Then installed squeakdbx in pharo from universe so ffi is installed as well.

I installed the latest vm (3.10-4 #2) from squeakvm.org web site as my previous vm was apparently without ffi (or could it be the plugin compiled in the VM?).



When trying to connect, I still have 'unable to find function address'.

FFI is pretty autist about what is going wrong.

Any clue?

As you can read in the FAQ, this is because FFI doesn't find openDBX library. Read this link and tell me if it works: http://wiki.squeak.org/squeak/6129#OpenDBX%20and%20FFI

To know this:

SmalltalkImage current listLoadedModules

In pharo, I would install FFI from ScriptLoader. Just like this:


ScriptLoader loadFFI.

I don't have it in my version of Pharo. I don't know if I can update it without going through a full pharo image which I don't want to do now.

Ok. Doesn't matter. Your current problem is not about FFI but you will have that problem then (when you get squeakDBX working). You only need to get the latests FFI version from MC to work in pharo with closure VM.

I am pretty sure the VM I used is not with the fixed closure. I am note sure about the image, I can tell you tomorrow the version number of the image when at the office.
Is the fixed closure mandatory to get SqueakDBX working?
Which Pharo # image and VM should be used?

I haven't my linux machine here, I will look tonight in my home, but:

> 1) what do you have /usr/lib in PATH ?

No it points only to binary as it should.
Does FFI looks at PATH for the libraries? If so it is a buggy behavior.
I am really currious to know how FFI find the libraries...

2) Just for testing, can you put the openDBX libraries in the same directory where the pharo
image is.

3) The same as 2) but where the VM is.

I will try tomorrow morning.

Thanks!

SqueakDBX works with both. If you use a closure image you must use a VM with closure an latest FFI (from MC). But, you can also use Squeak in older version (non closure) with FFI from Universes. So, no problem for you.

I am not sure about this. Perhaps someone (Andreas) can help us.
 

2) Just for testing, can you put the openDBX libraries in the same directory where the pharo
image is.

3) The same as 2) but where the VM is.

I will try tomorrow morning.

Which Linux are you using?  Perhaps there is a problem trying to resolve the library. The last test you can do (just to see if it works) is this:

Go t class OpenDBXUnix and change the methods

apiBind: handle database: databaseName name: userName password: password method: method

and

apiInitialize: handle backend: backend host: host port: port

In both, put module: 'libopendbx.so.1' or module: 'libopendbx.so' instead of module: 'opendbx'

I hope you get it working. Ask all what you want.

Greetings,

Mariano
 

Thanks!

It worked like a charm. I renamed all 'opendbx' occurrences to libopendbx.so.1

Thanks!
