[Mplapack-devel] Adjusting qd_real?

[Tony S. <sco...@ya...>]

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?

best wishes and thanks in advance
(some documentation would also be nice:-) )
