I am trying to install and use the biOps package on my x86_64 GNU/Linux ssytem. I have installed the fftw-3.2.2.tar.gz and biOps_0.2.1.tar.gz but when I start R and try to load the library, I get this message: ########################################## > library(biOps) Error in dyn.load(file, DLLpath = DLLpath, ...) : unable to load shared library '/usr/local/lib64/R/library/biOps/libs/biOps.so': /usr/local/lib64/R/library/biOps/libs/biOps.so: undefined symbol: fftw_execute Error: package/namespace load failed for 'biOps' ########################################## I am not clear what is missing - the installation did not indicate any problem, or any missing libraries. Thanks for any help on this. -- =========================================Prof. Jonathan M.
