I am having some trouble getting RMySQL installed. Thought there might be
some ideas out there. The problem:
MySQL 3.23.47 is installed (server,devel, client, benchmarks,shared) and
seems to be working. R 1.4.0 is working.
On first install attempt I get :
checking for mysql_init in -lmysqlclient... no
checking for /usr/local/include/mysql/mysql.h... no
checking for /usr/include/mysql/mysql.h... yes
Configuration error:
could not find the MySQL installation include and/or library
directories. Manually specify the location of the MySQL
libraries and the header files and re-run R CMD INSTALL.
following the instructions, I:
export MYSQL_DIR="/usr"
then,
R CMD INSTALL RMySQL_0.4-3.tar.gz
Seems to have solved the problem, no errors, help files built, etc. BUT...
library(RMySQL)
Error in dyn.load(x, as.logical(local), as.logical(now)) :
unable to load shared library
"/usr/local/lib/R/library/RMySQL/libs/RMySQL.so":
/usr/local/lib/R/library/RMySQL/libs/RMySQL.so: undefined symbol:
mysql_field_count
Error in library(RMySQL) : .First.lib failed
repeated the process on a similar (but apparently not the same) box - no
problems, didn't even have to specify the mysql home directory as a shell
variable.
Tried rebuilding R and MySQL - didn't help. Otherwise R and MySQL seem to be
working.
Has anyone seen this problem before? Thanks in advance.
