MAGMA Forum

Hi, this is the first time I've tried to use MAGMA/OpenCL. I'm on Linux Mint 18.2, and I've installed lapack and blas from the ubuntu repositories, and clBLAS from the github repository. My make.inc file is as follows:

------------------------------------------------------------------------------------
GPU_TARGET = AMD

CC = g++
FORT = gfortran

ARCH = ar
ARCHFLAGS = cr
RANLIB = ranlib

OPTS = -fPIC -O3 -DADD_ -Wall
FOPTS = -fPIC -O3 -DADD_ -Wall -x f95-cpp-input
F77OPTS = -fPIC -O3 -DADD_ -Wall
LDOPTS = -fPIC

# define library directories preferably in your environment, or here.
clBLAS = /opt/clBLAS
AMDAPP = /opt/AMDAPPSDK-3.0
LAPACKDIR = /usr/lib/lapack
BLASDIR = /usr/lib/openblas-base
-include make.check-clblas

#LIB = -lmkl_gf_lp64 -lmkl_gnu_thread -lmkl_core -lpthread -lm -fopenmp
LIB = -lclBLAS -lOpenCL -llapack -lopenblas

LIBDIR = -L$(clBLAS)/lib64 \
-L$(BLASDIR) \
-L$(LAPACKDIR)

INC = -I$(clBLAS)/include \
-I$(AMDAPP)/include
-------------------------------------------------------------------------------------------------------

I've compiled the library with "make shared" and/or "make lib" (I've "make clean"-ed multiple times trying different things) and it completes with no complaints. However, when I run "make test", I get the following errors:

Any help on what I could be doing wrong?

Oddly, I had to add clmagmablas/*.o in two places below to make the shared library. In clmagma-1.3.0/Makefile:
After that change, making tests worked. I don't remember having that problem before, but maybe we always compiled it as a static library, not a shared library.

(This old recursive Makefile structure really doesn't work well.)

Wow, that fixed it! Thanks!
