This is really odd, I've installed the binary of robustbase through synaptic on an ubuntu 8.04 machine and get: > library(robustbase) Error in dyn.load(file, DLLpath = DLLpath, ...) : unable to load shared library '/usr/lib/R/site-library/robustbase/libs/robustbase.so': libRlapack.so: cannot open shared object file: No such file or directory Error: package/namespace load failed for 'robustbase' > The package is where it is suposed to be: /usr/lib/R/site-library/robustbase is this not a problem at compiling? The problem is that if I try to install the source with install.packages("robustbase"), I get: gcc -std=gnu99 -shared -o robustbase.so R-rng4ftn.o init.o lmrob.o mc.o qn_sn.o rf-common.o rffastmcd.o rfltsreg.o wgt_himed.o -L/usr/lib/R/lib -lRlapack -lblas -L/usr/lib/gcc/i486-linux-gnu/4.2 -lgfortran -lm -L/usr/lib/gcc/i486-linux-gnu/4.2 -lgfortran -lm -L/usr/lib/R/lib -lR /usr/bin/ld: cannot find -lRlapack collect2: ld returned 1 exit status Despite the fact that I do have Rlapack: ~$ R CMD config LAPACK_LIBS -L/usr/lib/R/lib -lRlapack Am I doing something wrong?
