Re: plperl and table/record access

Thank you for the reply.

I seem to be having some difficulty with this module.

1) It doesn't install in the default RPM setup where the main PostgreSQL root
directory doesn't exist as such. The Makefile.PL expects the include and
libpq directories to all be under one directory, which isn't the case. I have
worked around this by making a /usr/local/postgresql directory and linking
the required directories into it, and then exporting POSTGRES_HOME to this
directory.

However, I then get the following error upon installation:

gcc -c -I/usr/local/postgresql/include -I/usr/local/postgresql/backend
-I/usr/local/postgresql/interfaces/libpq
-I/usr/lib/perl5/site_perl/5.6.0/i386-linux/auto/DBI -fno-strict-aliasing -g
-DVERSION=\"0.01\" -DXS_VERSION=\"0.01\" -fPIC
-I/usr/lib/perl5/5.6.0/i386-linux/CORE PgSPI.c
In file included from
/usr/lib/perl5/site_perl/5.6.0/i386-linux/auto/DBI/DBIXS.h:19,
from PgSPI.h:21,

/usr/lib/perl5/5.6.0/i386-linux/CORE/perl.h:3205: redefinition of `union
semun'
make: *** [PgSPI.o] Error 1

What am I doing wrong?

Regards.
