[Mplapack-devel] CUDA-related linkage error with mpack-0.8.0

[Sven H. <sv...@sv...>]

Hi.

I want to try mpack for solving some stiff ODEs, which have factors 
stretching over enough magnitudes to make using "double" quite problematic.

Therefore I compiled mpack-0.8.0 and stuck at a linkage error in the 
benchmark/mblas directory:

collect2: error: ld returned 1 exit status

make: *** [Rgemm.dd_cuda_total] Error 1

config:
all enabled - cuda, dd, qd, mpfr, gmp, __float128            or just 
cuda and dd
all that numeric libs from system (Debian)            or compiled from 
your package

environment:
Debian 8.0 aka testing/jessie
x86_64 or amd64
gcc / g++ 4.9
cuda toolkit 6.0.1

I could test the cuda stuff on a Quadro 4000 or maybe C2070.

I don't see a reason for the errors above. Please give me a hint, 
because I gave up after reading the source and trying out different 
configs. Maybe it's related to cuda toolkit version, but I'm not 
familiar with that stuff and its behaviour.

Thanks,
Sven
