I like to, especially when I'm installing a lot of
packages, some of which do not use DMGs. Anyhow, with
the help of Joe Conway and others, I solved the
problem, and here is the summary:
When installing plr 22.214.171.124 into
postgresql-8.2.0 on OS X 10.4, if you get the "Cannot
build PL/R because libR is not a shared library"
1. Make sure that $R_HOME is set correctly. Mine is
now set to:
and as a result make can find the lib files it's
2. Make sure that the same version of gcc used to
compile postgresql is used to compile plr. I used gcc
4.0 for both. (Since the default for OS X is 3.3, I'm
guessing that the postgresql configure file makes its
a. The default gcc version can be discovered and
changed on OS X with gcc_select
b. The version of gcc used to compile postgresql can
be discovered within the psql shell:
postgres=# select version();
with a result that looks like:
PostgreSQL 8.2.0 on powerpc-apple-darwin8.8.0,
compiled by GCC powerpc-apple-darwin8-gcc-4.0.0 (GCC)
4.0.0 20041026 (Apple Computer, Inc. build 4061
