Hello, I am trying to call the BLAS Level1 function zdotc from R via a .C call like this: #include "R.h" #include "R_ext/BLAS.h" void testzdotc() { Rcomplex zx[3], zy[3], ret_val; zx[0].r = 1.0; zx[0].i = 0.0; zx[1].r = 2.0; zx[0].i = 0.0; zx[2].r = 3.0; zx[0].i = 0.0; zy[0].r = 1.0; zy[0].i = 0.0; zy[1].r =...

...ll compilers using the same linkage conventions (those of pcc) whereas users of other platforms are used to the idea that code from different compilers cannot in general be mixed. This is no longer true for gfortran on AMD64. Given a double complex function like double complex function zdotc(n,zx,incx,zy,incy) gfortran returns the result in a 128-bit XMM SSE register, whereas g77 (and gcc using Rcomplex) would return the result in memory. The result is that a BLAS compiled with g77 or gcc is not compatible with R compiled with gfortran and attempts to use the combination results in...

...group methods when caching was off (as it is by default). o dev.copy2pdf(out.type = "cairo") gave an error. (PR#14827) o Virtual classes (e.g., class unions) had a NULL prototype even if that was not a legal subclass. See ?setClassUnion. o The C prototypes for zdotc and zdotu in R_ext/BLAS.h have been changed to the more modern style rather than that used by f2c. (Patch by Berwin Turlach.) o isGeneric() produced an error for primitives that can not have methods. o .C() or .Fortran() had a lack-of-protection error if the regist...
