Hi, All I have a linux system of Mandriva-2007 with R version 2.3.0 and MySQL with 5.0.0. I have also got DBI-R database interface version-0.1-11 installed on my Linux system.While installing RMySQL package version 0.5-11 but facing the problem mentioned below . * Installing *source* package 'RMySQL' ... creating cache ./config.cache checking how to run the C preprocessor... cc -E checking for compress in -lz... yes checking for getopt_long in -lc... yes checking for mysql_init in -lmysqlclient... no checking for mysql.h... no checking for mysql_init in -lmysqlclient... no checking for mysql_init in -lmysqlclient... no checking for mysql_init in -lmysqlclient... no checking for mysql_init in -lmysqlclient... no checking for mysql_init in -lmysqlclient... no checking for /usr/local/include/mysql/mysql.h... no checking for /usr/include/mysql/mysql.h... no checking for /usr/local/mysql/include/ mysql/mysql.h... no checking for /opt/include/mysql/mysql.h... no checking for /include/mysql/mysql.h... no 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. INSTRUCTIONS: 1. Define and export the 2 shell variables PKG_CPPFLAGS and PKG_LIBS to include the directory for header files (*.h) and libraries, for example (using Bourne shell syntax): export PKG_CPPFLAGS="-I<MySQL-include-dir>" export PKG_LIBS="-L<MySQL-lib-dir> -lmysqlclient" Re-run the R INSTALL command: R CMD INSTALL RMySQL_<version>.tar.gz 2. Alternatively, you may pass the configure arguments --with-mysql-dir=<base-dir> (distribution directory) or --with-mysql-inc=<base-inc> (where MySQL header files reside) --with-mysql-lib=<base-lib> (where MySQL libraries reside) in the call to R INSTALL --configure-args='...' R CMD INSTALL --configure-args='--with-mysql-dir=DIR' RMySQL_<version>.tar.gz ERROR: configuration failed for package 'RMySQL' ** Removing '/usr/lib/R/library/RMySQL' Any help will be great.
