 Hi,

Yes! The server was built elsewhere... Are you saying that PL/Java
should always be built on the same server as the server itself? That is
kind of a severe restriction, esp. when we have pg_config etc - to tell
us all the flags that were used and essentially that should be all that
should be known. Anyhow, I was quite convinced that the way I built it
was fine - was just wondering why I got that error in the first place.

Thanks,
Janardhan

The definition of HAVE_UNSETENV should be in 
$DBHOME/include/postgresql/server/pg_config.h and matches up with what 
the server compile environment found.  This could be different than the 
pljava compile environment if the server was built on a different 
machine or if additional libraries were installed after the server 
build.  If you build the server and then immediately build pljava 
against that server it should definitely work.  Can you clarify how your

server was built?
