Hi,
I have some trouble building 1.0.0-RC3 on a 2.6.35-rc4_performance kernel x86_64 GNU/Linux with Intel MKL 11.1.072 and CUDA3.2. Here are the errors.

Would you please help? Thanks a lot.
Best,

Thank you for this bug report. We fixed it. Until we post the new version you can just take out zgeev.cpp from the Makefile to compile the rest of the library, or fix it (the problem is compiler dependent, the way certain functions are declared).

Thanks, Stan.
Could you tell me how to fix it? If I simply take zgeev.cpp out, what will be the consequence?
Best,
xunlei

Xunlei,
zgeec.cpp is the LAPACK's zgeev with certain parts replaced by their MAGMA equivalents. Your compiler gives errors on the way some of the dependencies are declared and this has to be fixed. Removing zgeev.cpp from the Makefile will result in zgeev not being included in the library. There are no other files (except the testing_zgeev) that depend on it. We will post in a day or two our fix (I am not posting it now because our changes are in several files and we are still testing it).

Hi Stan,
There are similar errors beyond just zgeev.cpp. These errors happen to zheevd.cpp, zgesvd.cpp. After taking these three files out of Makefile, I ran into more errors listed below.

ifort -O3 -DADD_ -DGPUSHMEM=130 -I/hpc_shared/apps/RHEL-5/x86_64/cuda/cuda-3.2/cuda/include -I../include -I../quark/include -J../include -c magma_zfortran.f90 -o magma_zfortran.o

Please let me know when there is a fix for them. Thanks a lot.

Hi Xunlei,
Thanks for this report too! We are going to look into it.
The easiest fix for now may be to just use gfortran instead of ifort.

Hi Stan,
While playing with MAGMA, I found a minor typo in a Makefile that prevents building correctly the library.

In magmablas/Makefile line 123:
you have:

Code: Select all: $(NVCC) $(NVOPTS) $(GPUOPT) $(INC) -c $< -o $@

and it should be NVOPT (without the S)

Code: Select all: $(NVCC) $(NVOPT) $(GPUOPT) $(INC) -c $< -o $@

Cheers,
Julie

Julie,
Good catch. Thanks!
We were looking yesterday with Don trying to figure out why the "-DADD_" option was not passed to the compiler, not seeing that actually no option was passed.

What is the missing package in Ubuntu 10.04 ???

Stan, xunlei,

First, thank you, Stan, and your colleagues, for your great work!

I had the similar errors xunlei mentioned, and was able to fix them and get magma rc3 compiled with mkl and intel compilers. Basically, the function references could be fixed by hand, and also I turned off the least fortran example in testing.

In case it could be useful, attaching diffs and make.inc (sorry, forum won't let me to attach files).
