I am moving a users R based system to a new Linux installation: 3.10.0-327.13.1.el7.x86_64 #1 SMP Thu Mar 31 16:04:38 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux I have R installed but the user needs Cairo. I got the latest version of Cairo package: Cairo_1.5-9.tar.gz Then I do the following for installation under the users directory which is where she needs it do R library call R CMD INSTALL -l /home/dsvehla/R Cairo_1.5-9.tar.gz I get the following every time - even if I use older versions of the package: ** R ** preparing package for lazy loading ** help *** installing help indices ** building package indices ... ** testing if installed package can be loaded Error : .onLoad failed in loadNamespace() for 'Cairo', details: call: dyn.load(file, DLLpath = DLLpath, ...) error: unable to load shared object '/home/dsvehla/R/Cairo/libs/Cairo.so': /home/dsvehla/R/Cairo/libs/Cairo.so: undefined symbol: cairo_surface_write_to_png Error: loading failed Execution halted ERROR: loading failed * removing ‘/home/dsvehla/R/Cairo’ No matter where I look I cannot find an answer to this issue - I have installed all ( I think ) dependencies for Cairo but still no go.
