A while back I posted to this group that I was having difficulty compiling packages that used BLAS and Lapack on an Ubuntu 32-bit system. I looked a little further into the issue and discovered that the /usr/lib/R/etc/Makeconf files are different on the 32-bit and 64-bit Ubuntu packages maverick/r-base-core_2.12.1-1maverick0_i386.deb and the corresponding 64-bit version. The Make variable BLAS_LIBS is defined as -lblas on the 64-bit system $ egrep BLAS /etc/R/Makeconf BLAS_LIBS = -lblas but on the 32-bit system it is defined as -lf77blas -latlas
Difference in the BLAS_LIBS definition on Ubuntu packages

Doug, Thanks for finding that. Checking with some other builds (Debian. mainly), it appears that the amd64 version is correct with: BLAS_LIBS = -lblas Due to the loss of a server, we are in a temporary holding pattern in terms of updating the Ubuntu packages on CRAN. That should be corrected soon. However, if you are interested in getting a i386 version without "-lf77blas -latlas", you can use my Launchpad PPA: https://launchpad.net/~marutter/+archive/rrutter Michael
