Hi all,
I am currently trying to create a development environment
including PostgreSQL 8.0.0rc1, R 2.0.1 and PL/R on a system running Fedora Cora 1.
So far, I have suceeded in setting up PostgreSQL and R as
a shared library - unfortunately I have not been able to link these
two spheres by adding the PostgreSQL add-on PL/R due to
some mysterious probs.
I thoroughly followed the setup instructions for PL/R (see
http://www.joeconway.com/plr/doc/plr-install.html)
and arrived at being able to register PL/R with PostgreSQL properly and
even to create PL/R-specific functions.
>But< whenever trying to invoke these functions, I end up with
a single exception, even for simple ones which are just supposed to return
the previously passed arguments:
######snip#######
- ERROR: R interpreter parse error
######snip#######
A closer look at the postmaster's/ postgres's log-file reveals that a hardly more
specific exception is thrown at this level, i.e.:
######snip#######
- ERROR: R interpreter parse error
- DETAIL: R parse error caught in "PLR17706 <- function(arg1,arg2) {
- if (arg1 > arg2)
- return(arg1)
- else
- return(arg2)
- }".
- CONTEXT: In PL/R function r_max
######snip#######
Even gdb monitoring did not provide any further hint, using older PostgreSQL, R and PL/R versions
didn't make a difference.
I would kindly ask for your help and thoughts!
best regards,
Stefan
