...gs from C to Fortran. Indeed, BLAS and LAPACK define a large number of subroutines that take one or more explicit single-character strings as arguments. Other than that, BLAS has only one function (xerbla), which takes a string of unspecified length, LAPACK only has four (ilaenv, ilaenv2stage, lsamen, xerbla). The C interfaces to BLAS/LAPACK from Netlib depend on the historic behavior that explicit single-character strings are interoperable, concretely CBLAS and LAPACKE provide C interfaces/code that calls into Fortran BLAS/LAPACK without passing the 1s as lengths of the character strings...

Hi, I have tried to pinpoint potential problems which could lead to the LAPACK issues that are currently seen in R. I built the current R trunk using AR=gcc-ar RANLIB=gcc-ranlib ./configure --prefix=$HOME --enable-lto --enable-BLAS-shlib=no --without-recommended-packages and used this to find problem areas. There are quite a few warnings that were flagged, due to mismatches in function

...nks against that. For the pros and cons see the R-admin manual. The defaults are now --without-blas (so you have explicitly to ask for an external BLAS), and --enable-BLAS-shlib unless a usable external BLAS is found or on AIX or on MacOS X 10.2 and earlier. o MacOS X did not like having LSAME in both BLAS and LAPACK libraries, so it is no longer part of the R-internal LAPACK. We now require an external BLAS to provide LSAME: it seems that nowadays all do. o The configure test for 'whether mixed C/Fortran code can be run' has been improved as on one system that test pass...
