[R] [ROracle] error loading (undefined symbol: sqlclu)

[Mathieu Drapeau]

I have this error when I load the library ROracle:
> library(ROracle)
Loading required package: DBI
Error in dyn.load(x, as.logical(local), as.logical(now)) :
        unable to load shared library
'/usr/local/lib/R/site-library/ROracle/libs/ROracle.so':
  /usr/local/lib/R/site-library/ROracle/libs/ROracle.so: undefined
symbol: sqlclu
Error in library(ROracle) : .First.lib failed for 'ROracle'
>

Also, my LD_LIBRARY_PATH seems to be set correctly:
drapeau:~> echo $LD_LIBRARY_PATH
/home/drapeau/lib:/opt/oracle/xe/app/oracle/product/10.2.0/client/lib

I installed the big database applications (10g) and ROracle 0.5-7

Your help will be very appreciated to help me solve this error,
Thank you,
Mathieu
