Hi, I am trying to test out the scripts here as a proof of concept http://www.r-bloggers.com/integrating-php-and-r/
However, I am not able to reproduce the output graph in the browser. Rscripts is working fine as I run the command "Rscript /home/username/R/testscript.R 1000" for example, and a png graph is output as expected, and I can output it to any folder where I have permission by changing testscript.R. However I am not able to get the output on the browser.I checked the web root on my test server (xampp for Linux) and found that a pdf file is created instead (Rplots.pdf) I checked xampp's error log and found these, I think it is the reason why a png graph is not created by using php's exec() command. "unable to load shared object '/usr/lib/R/library/grDevices/libs//cairo.so': /usr/lib/i386-linux-gnu/libfontconfig.so.1: undefined symbol: FT_Select_Size" I notice that there are two forward slashes in "..grDevices/libs//cairo.so" whereas it should be just "..grDevices/libs/cairo.so" I am wondering if this is a problem. Also it seemed to be working before. It somehow stops today. I am using Ubuntu 11.04 and R 2.14.2 (from this ppa https://launchpad.net/~marutter/+archive/rrutter) and my test server is xampp for Linux, I would appreciate any help. Thank you. -- View this message in context: http://r.789695.n4.nabble.com/cannot-load-shared-object-usr-lib-R-library-grDevices-libs-cairo-so-tp4471075p4471075.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.
