[fdo-users] PostGIS provider undefined symbols

[Greg]

Hello

I've just built Mapguide 2.1 along with FDO 3.4 on a Linux box which
was a bit tricky - to say the least.
Now I have a problem with the PostGIS provider, I came across a
similar case in another thread, but it was left unresolved and it's an
old thread,
I hope someone will be able to help now, I get some undefined symbols
for the provider.
I checked on the other FDO libraries with nm and it turned out that
the functions _ZN*CreateEv are actually defined in the library called
libExpressionEngine.so.
So why aren't they resolved correctly? Isn't the function "crypt" the
standard Unix function?
I could dig into the source code and come up with an answer but it
would probably take me a few weeks as I'm rusty on Linux programming,
and I'm in a bit of a hurry.
Could someone please help me out on this problem? Thanks in advance.

Regards, Greg
