Uwe, now I've tried these steps, following RMySQL installation instructions (http://cran.r-project.org/web/packages/RMySQL/INSTALL):
1. Download the RMySQL_0.9.tar.gz file to the folder C:\Program Files\R\R-2.15.1\bin\x64 2. Open a Windows command line, and change directory to that folder 3. Enter the following commands: set MYSQL_HOME=C:\\Program Files\\MySQL\\MySQL Server 5.5 R CMD INSTALL RMySQL_0.9.tar.gz The output ends with: "gcc.exe: error: C:\Program Files\MySQL\MySQL Server 5.5/bin/libmySQL.dll: No such file or directory ERROR: compilation failed for package 'RMySQL' * removing 'C:/Users/Acer/Documents/R/win-library/2.15/RMySQL' " The problem seems to be that it points to an incorrect folder to find the file 'libmySQL.dll' . This file is located at 'C:\Program Files\MySQL\MySQL Server 5.5/lib' -- View this message in context: http://r.789695.n4.nabble.com/RMySQL-install-on-windows-tp4645629p4649510.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
