I thought I would try compiling R this time with the ATLAS libraries. I have compiled ATLAS and I have the following libraries: libatlas.a libf77blas.a libptcblas.a libtstatlas.a libcblas.a liblapack.a libptf77blas.a Is it sufficient to use ' --with-blas=libatlas.a ' when configuring or do I need to specify any of the other libraries as well? -- William D.

...he troublesome library: $ nm /home/akramer/R-2.7.2/modules//lapack.so | grep cblas_izamax U cblas_izamax ...the function is not there. However, referring to my configure line, the function is indeed in the libraries I passed to R: [akramer at dev170 ~/R-2.7.2] nm /usr/local/lib/libptcblas.a | grep cblas_izamax 0000000000000000 T cblas_izamax ...so, it appears to me that there is a problem in R building lapack.so.
