Hi folks!

I have a problem with SqueakDBX and FFI. I install openDBX from a .deb and I
get this:

ldconfig -p | grep opendbx   show the same as you:
    libopendbxplus.so.1 (libc6) => /usr/lib/libopendbxplus.so.1
    libopendbx.so.1 (libc6) => /usr/lib/libopendbx.so.1

The problem is that we (in squeakDBX) have as module: opendbx. Linux looks
for libMODULE_NAME.so.

In this case, was searching libopendbx.so. But, my file was named
libopendbx.so.1. And of course, I got a 'unable to find function address'.

Solution: copy and rename (or just rename) libopendbx.so.1 to libopendbx.so
and worked like a charm.

But, the question is, shouldn't FFI resolve this ? is this a matter of the
linker ?

Thanks for the help!

Mariano

I think I fix it :)

I took a clean Ubuntu. I did:

sudo dpkg -i libopendbx1_1.4.0-1_i386.deb libopendbx1-mysql_1.4.0-1_i386.deb


Then  ldconfig -p | grep opendbx   show the same as you:

    libopendbxplus.so.1 (libc6) => /usr/lib/libopendbxplus.so.1
    libopendbx.so.1 (libc6) => /usr/lib/libopendbx.so.1

The problem is that we have as module: opendbx. Ubuntu looks for
libMODULE_NAME.so.

In this case, was searching libopendbx.so. But, your (and my) file was named
libopendbx.so.1.

Solution: copy and rename (or just rename) libopendbx.so.1 to libopendbx.so
and should work like a charm.

Thanks for your testing Hilaire. We want SqueakDBX to be as much easier as
possible. So, documenting the wiki with several cases will definitively help
us. I add this information to the wiki.

Let me know if that work.

Cheers,

Mariano
