Dear Everybody, install.packages("Cairo") returns [...] * Installing *source* package 'Cairo' ... checking for gcc... gcc-4.2 -std=gnu99 checking for C compiler default output file name... configure: error: C compiler cannot create executables See `config.log' for more details. ERROR: configuration failed for package 'Cairo' ** Removing '/usr/local/lib/R/site-library/Cairo' [...] So, will I have to configure around in gcc? Can anybody describe me how to do that? Thank you in advance. Leberl
