Problem with building tesing

[Linuxboy]

Hi! I've got the error when trying to build testing
linuxboy@CudaDesktop:~/magma_1.1.0/testing$ make

What I do wrong?

It looks like your make.inc is correct. If you have a Fermi GPU you may have to change "GPU_TARGET = 0" to "GPU_TARGET = 1".

Routine magma_zpotrf is part of libmagma.a. Did the compilation in "src" go through without problems? You can go to the src directory and type "make" to just verify that everything is fine. If everything is fine the routine would be added to the library. On my system if I check whether I have it, I get

[tomov@cumin trunk]$ nm lib/libmagma.a | grep magma_zpotrf | grep T

Hi Stan!
I decide to build magma from the beginning

make.inc

GPU_TARGET = 1

CC = gcc
NVCC = nvcc
FORT = gfortran

ARCH = ar
ARCHFLAGS = cr
RANLIB = ranlib

OPTS = -O3 -DADD_
FOPTS = -O3 -DADD_ -x f95-cpp-input
NVOPTS = --compiler-options -fno-strict-aliasing -DUNIX -O3 -DADD_
LDOPTS = -fPIC -Xlinker -zmuldefs

LIB = /usr/lib/lapack/liblapack.a \
-lf77blas -latlas -lcblas -lf2c -lcublas -lm

CUDADIR = /usr/local/cuda

LIBDIR = -L/usr/lib/atlas-base \
-L/usr/lib/lapack \
-L$(CUDADIR)/lib64
INC = -I$(CUDADIR)/include

LIBMAGMA = ../lib/libmagma.a
LIBMAGMABLAS = ../lib/libmagmablas.a

Now I got this

../lib/libmagma.a(zlatrd.o): In function `magma_zlatrd':
zlatrd.cpp:(.text+0x443): undefined reference to `zdotc'
zlatrd.cpp:(.text+0xe54): undefined reference to `zdotc'

Stan! All is ok for me - I don't need z_routines.
