Hi all, I want to install some packages in R in a computer where I haven't root privilegues, and R is already installed. The system manager is extremely busy and at the moment I'm afraid that I have to manage my own installations. So, I am trying to install 'quadprog' and I'm getting the message: /usr/bin/ld: cannot find -lblas collect2: ld returned 1 exit status make: *** [quadprog.so] Error 1 ERROR: compilation failed for package 'quadpr on the other hand in the system there is a /usr/lib64/libblas.so.3 but not a libblas.so. Thus I've created the soft link in my $HOME/lib/libblas.so and set LD_LIBRARY_PATH=$HOME/lib I would expect that 'quadprog' to find the link but the message is still the same. Please, could you tell me how to specify to "R CMD INSTALL quadprog" where to find libblas.so? Thanks in advance, Javier ---
