Problem building mkl-fftw wrapper library

rob_n_ — Fri, 20 Dec 2013 03:04:54 GMT

Hello,

I am attempting to build the mkl-fftw wrappers, as I am compiling a program that uses FFTW3 and claims to benefit from the mkl-wrapper. When I execute the following:

cd /opt/intel/mkl/interfaces/fftw3xf
sudo make libintel64

I get command not found:

primary@localhost: fftw3xf$sudo make libintel64
make -f makefile lib _IA=intel64
make[1]: Entering directory `/opt/intel/composer_xe_2013_sp1.1.106/mkl/interfaces/fftw3xf'
rm -rf ./obj_intel
mkdir -p ./obj_intel
icc -vec-report0 -I../../include -I../../include/fftw -c ../../interfaces/fftw3xf/wrappers/fftw_cleanup.c -o obj_intel/fftw_cleanup.o
make[1]: icc: Command not found
make[1]: *** [obj_intel/fftw_cleanup.o] Error 127
make[1]: Leaving directory `/opt/intel/composer_xe_2013_sp1.1.106/mkl/interfaces/fftw3xf'
make: *** [libintel64] Error 2

It would seem to my untrained eye that one of the icc flags is innapproprate.

If I run the same command with the gnu compiler, all works well. (make libintel64 compiler=gnu)

I am running Fedora20 with the latest Intel Parallel Studio XE package (ifort/icc 14.0.1) and gcc 4.8.2

I'm sure this has been addressed before; however, I searched the forum and did not find an answer to my dilema.

Appreciatively,

Robert

look at the line of the message: make[1]: icc: Command not found

you need to launch something like that first of all :

source //opt/intel/composer_xe_2013_sp1.1.106/bin/compilervars.sh intel64

to setup the compiler's environment...

I don't think that is the

rob_n_ — Fri, 20 Dec 2013 05:07:15 GMT

I don't think that is the problem. I have set up the compiler environment.

I don't believe it is saying the command "icc" is not found, I believe the compiler is saying it did not find the command/flag. I could be wrong, as I'm not at all in my comfort zone here, but if I type icc, I do not get "command not found."

I checked how it will work on

I checked how it will work on my side - I don't see problem.

I don't know why mine does

rob_n_ — Fri, 20 Dec 2013 21:38:00 GMT

I don't know why mine does not work. I can say I am not an isolated case. I actually have a colleague that has recently set up Ubuntu on his computer to run the same program I wish to run. In the manual it recommends building and using these wrappers so he of course attempted this as well. He informed me that he also had errors trying to compile the mkl-fftw3 wrappers with the intel compiler.

You can see the gnu compiled library is present, as it compiles when I specify the gnu compiler.

Also, when I attempt to make the wrapper in dir fftw3x_cdft, neither compiler works

I'm honestly not sure what the difference is between fftw3xc, fftw3xf, and fftw3x_cdft are. I assumed the c and f corresponded to c compiler and fortran compiler, but I don't know why that would be necessary.

That happens because icc and

Dmitry_B_Intel — Fri, 10 Jan 2014 07:32:00 GMT

That happens because icc and mpiicc are not seen under sudo. You can check this by running 'sudo icc -V'. Please notice that 'sudo gcc' works.

My recommendation is not use sudo. Cd to your working directory. Set MKLROOT=/opt/intel/composer_xe_2013_sp1.1.106/mkl. Run

make -f $MKLROOT/interfaces/fftw3xc MKLROOT=$MKLROOT libintel64

fftw3xc provides wrappers for use from C/C++, fftw3xf provides wrappers for use from Fortran.

Thanks
Dima

I am having the same issue.

I am having the same issue. The last comment by Dmitry did not help. Please give me some suggestion.

This is a very old thread, but it helped me to figure out the problem, so I hope that this comment can help someone as well.

Dimitry's answer was correct, icc is indeed not found under sudo.

However, his make command did not work for me. What did was to run:

make libintel64 INSTALL_DIR=$HOME

in the

$MKLROOT/interfaces/fftw3xf

directory.

Of course I sourced the intel compiler vars first.
