[pclasses-devel] weird undef symbol error on loading mysql driver?

[stephan b. <st...@s1...>]

i'm stumped on this one:

i can build and run demo/sql.cpp from the source tree, but when a client 
lib i build in another tree tries to do the same stuff, namely open 
psql_mysql.so, i get an undef symbol:

factory.addPlugin("psql_mysql.so");
...

PSqlSerializer.cpp:68 : Error from 
P::Classes: /home/stephan/cvs/inst/lib/pclasses/psql_mysql.so: 
undefined symbol: _ZTIN1P9SQLBigIntE

i'm linking against all of the P libs except the plugins:

stephan@owl:~/cvs/s11n.net/ps11n/src> ldd psql_serializer.so
...
        libpcore.so.1 => /home/stephan/cvs/inst/lib/libpcore.so.1 
(0x400ce000)
        libpcrypto.so.1 => /home/stephan/cvs/inst/lib/libpcrypto.so.1 
(0x40238000)
        libpio.so.1 => /home/stephan/cvs/inst/lib/libpio.so.1 
(0x40245000)
        libpnet.so.1 => /home/stephan/cvs/inst/lib/libpnet.so.1 
(0x4025c000)
        libpsql.so.1 => /home/stephan/cvs/inst/lib/libpsql.so.1 
(0x40292000)
        libps11n.so => ./libps11n.so (0x402a4000)
...

If i add psql_mysql.so to my links it works, but i shouldn't have to do 
this from the client side.

i also tried opening the DLL with own dll opener, and get the same 
error:

class_loader.cpp:110 : Error opening 
DLL: /home/stephan/cvs/inst/lib/pclasses/psql_mysql.so: undefined 
symbol: _ZTIN1P9SQLBigIntE


Any ideas where to look to solve this?
