Magma 2.0.2 installation help

[ah2012]

Hi all,

I'm having trouble installing Magma 2.0.2 on Ubuntu Server 16.04. I've edited the MKL-GCC makefile with the directories of my Cuda and MKL libraries. When I initiate the makefile,

The process begins, but it exits with with the first call to nvcc Error 1:

Code: Select all

Makefile:570: recipe for target 'magmablas/saxpycp.o' failed

The -I option for this line nvcc lists the correct directly for both the Cuda and MKL include directories.

Any help would be tremendously appreciated!

Can you include your make.inc file, and the nvcc command that fails? It's hard to tell what's going on from just the error message.

Hi Mark,

Thanks for the fast reply. Here is the make.inc file:

Thank you again!

I should also mention I've edited the LIB definition in the make.inc for MKL to reflect the Link Advisor for my version of the Library. I've tried the make.inc file without these alterations, and I receive the same error.

Searching for the error message "/usr/include/string.h:652:42: error: ‘memcpy’ was not declared in this scope",
I found these suggestions, among others. It seems an issue in the system compiler's headers and their interaction with nvcc.

Probably you can modify the NVCCFLAGS in make.inc to accommodate the suggestions.
