Hello again Still no documentation but by attrition, I figured out some of my previous problems. I needed to switch on the FORTRAN wrapper for IFORT and through a GMP test case work out the link to the libraries. I also managed to get the examples in dd and gmp working. I got D. Bailey's qd packageand enabled qd in mpack only to find that -> mblas.h in the 'include' sub-directory has qd_real = REAL i.e. single precision which is NOT quad i.e. double-double precision If I change it to e.g. qd_real to e.g. LONG DOUBLE or ____FLOAT128, I canconfigure but the make creates an error on the first BLAS routine it tries to compile. I see previous messages claiming that double-double works but I would like to know how. Does the build require CUDA? Can someone tells me how to make build the libraries so that I can get double-doubleprecision for MBLAS and MLAPACK? email is: 279...@qq... best wishes and thanks in advance (some documentation would also be nice:-) ) |
