R-patched and R-devel
If I configure in R-patched and R-devel, with the same options to
configure, then R-patched says
checking for ATL_xerbla in -latlas... yes
checking for cblas_dgemm in -lcblas... yes
checking for dgemm_ in -lf77blas... yes
which R-devel says
checking for ATL_xerbla in -latlas... yes
checking for cblas_dgemm in -lcblas... yes
checking for dgemm in -lf77blas... no
This is on the same computer and using the same libraries. Observe
in R-patched we check for dge...

Can't get F77_CALL(dgemm) to work [SEC=UNCLASSIFIED]
...earched the internet and suspect it has something to do with column
major matrix format for Fortran being inconsistent with the row major
format for C but I'm not sure how to fix this in C. One suggestion I came
across (http://icl.cs.utk.edu/lapack-forum/viewtopic.php?f=2&t=915) is to
use cblas_dgemm in which the option 'CblasColMajor' can be specified.
However, I would have thought that F77_CALL(dgemm) should work as it has
been used in some R packages. I'm also not sure that cblas would work from
R.
I tried inputting matrices into dgemm as 2 dimensional arrays and as one
dimensi...
