[R] RMySQL & couldn't find function ".valueClassTest"

[Trond Rafoss]

Hi Arend, I had the same problem on RH 9 as you, but the tip on http://stat.bell-labs.com/RS-DBI/download/index.html at the bottom telling:

""""""""""""""""""""""""""""""""""""""""" 
The following are some workarounds: 

append the line 
export(.valueClassTest)

to the file $R_HOME/src/library/methods/NAMESPACE where $R_HOME refers to the directory where you have R 1.8.0 installed. 
""""""""""""""""""""""""""""""""""""""""""

fixed the problem for me, and I can use RMySQL successfully on RedHat 9 !

Regards, Trond Rafoss

I compile MySQL from source and do have the client libraries installed
(I can run mysql from a terminal)  However, I was able to compile RMySQL
by:

# export PKG_CPPFLAGS="-I/opt/mysql/include"
# export PKG_LIBS="-L/opt/mysql/lib -lmysqlclient"
# R CMD INSTALL RMySQL_0.5-2.tar.gz

Now I am having the problem that was mentioned at 

http://stat.bell-labs.com/RS-DBI/download/index.html

with

> m <- dbDriver("MySQL")
> Error in dbDriver("MySQL") : couldn't find function ".valueClassTest"

One of the solutions was to patch R 1.8.0.  I downloaded R-release.diff.gz but I am not
sure what to do with it.  Does anybody know of any documentation that can
guide me ?

Thanks again,
Arend van der Veen
