[R] libpq-fe.h ???

[Miha STAUT]

Hi all,

I tried to install the Rdbi_0.1-2.tar.gz and Rdbi.PgSQL_0.1-2 package. The 
Rdbi_0.1-2.tar.gz installed fine but the Rdbi.PgSQL_0.1-2 had some problems. 
The compilation routine tried to  find a header called libpq-fe.h but did 
not find it in the standard locations. I searched through the computer but 
did not find a file called in this way either. What should I do to 
successuffly install this package? In the Netleters introduction to R/GRASS 
interface there is  no mention about this problems.

The PostgreSQL_7.2.1 Users guide states: "Frontend programs that use libpq 
must include the header file libpq-fe.h and must link with the libpq 
library." Is Libpq a package that can be downloaded and how should I create 
this header and make a link to it?

I use R 1.6.2.1 and PostgreSQL 7.2 with RedHat 7.3.

I could not find your PostgreSQL client headers!
Use --with-pgsql-includes=PATH; if running R's INSTALL,
use --configure-args='--with-pgsql-includes=PATH'; or
set PG_INCLUDE_DIR in your environment to the library path,
and rerun the configure/install.
