Building Julia 0.6.0 with MKL on OSX 10.12.5

General Usage
1

Hello,

I am new to this so please forgive my naive approach.

I have been trying to build Julia using the intel MKL in addition to the intel c++ and fortran compilers on OS X 10.12.5. However, I have been running into a bunch of errors, which I suspect is a result of me digging myself into a deeper hole rather than solving the underlying problem(s).

Since I am new, I did a sanity check and built Julia from the most recent stable source, which appears to have worked fine (I can launch julia and use it to confirm that 1+1 indeed equals 2).

To then build with the intel math library and compilers, in the command line I entered:
source /opt/intel/mkl/bin/mklvars.sh intel64 ilp64

Then I made a Make.user file containing the following:

USEICC = 1
USEIFC = 1
USE_INTEL_MKL = 1
USE_INTEL_LIBM = 1

When I enter the make command I immediately get the error:
julia/Make.inc:431: *** USE_LIBCPP only supported with clang. Try setting USE_LIBCPP=0. Stop.

However, adding in USE_LIBCPP=0 into the Make.user file does not resolve this error.

In an attempt to get around this problem, I added in the line
override USE_LIBCPP=0
into my Make.user file.

While this indeed gets the building to start moving, I see a very large number of warning messages while building CXX objects where the following warning numbers appear to be repeated over an over again:

warning #1292: unknown attribute “returns_nonnull”
warning #2026: Effective C++ Item 14 Make sure base classes FoldingSetImpl have virtual destructors

and eventually it terminates on the following error:

configure: error: compiler does not halt on function prototype mismatch.
make[1]: *** [scratch/curl-7.53.1/build-configured] Error 1
make: *** [julia-deps] Error 2

If anyone can provide some advice on how to get around this problem, I would greatly appreciate it!

Do you really need to built with the intel compilers? You can use MKL anyway.

I was under the impression that the intel compilers would improve performance, is that not true?

Assuming that these compilers are not needed, I changed the Make.user file to just the following

USE_INTEL_MKL = 1
USE_INTEL_LIBM = 1

However I now get the following error

Undefined symbols for architecture x86_64:
“__intel_fast_memcpy”, referenced from:
_amd_2 in libamd.a(amd_i_2.o)
_amd_l2 in libamd.a(amd_l_2.o)
“__intel_fast_memset”, referenced from:

If you are working in the same directory where you started, it is probably necessary to run make distclean-suitesparse (and quite likely make distcleanall) to clean the existing (partial?) builds started with ICC.

Code generation is doen by LLVM so runtime performance AFAIU, run time performance should not depend on what you use to compile LLVM / Julia with.

Indeed that was the problem there! I now have a new bug:

LoadError(“sysimg.jl”, 362, LoadError(“sparse/sparse.jl”, 41, LoadError(“sparse/umfpack.jl”, 61, ErrorException(“error compiling anonymous: could not load library "libsuitesparse_wrapper"\ndlopen(libsuitesparse_wrapper.dylib, 1): Library not loaded: @rpath/libmkl_rt.dylib\n Referenced from: /Applications/julia/usr/lib/libcholmod.dylib\n Reason: image not found”))))
*** This error is usually fixed by running make clean. If the error persists, try make cleanall. ***
make[1]: *** [/Applications/julia/usr/lib/julia/sys.o] Error 1
make: *** [julia-sysimg-release] Error 2

I have run both make clean and make cleanall but the error message persists. I thought that perhaps there was something still lingering from my previous build attempts, so I deleted everything and started with a fresh directory. However, I still get this error.

Just an update. I tried building with the intel compilers on Ubuntu 16.04.2 LTS and also ran into some problems there, although the errors were unrelated to what I saw in OSX. However, unlike in OSX, I was able to build and install with a Make.user file that just contained USE_INTEL_MKL = 1

I am wondering then, are the directions listed in the readme file for building with the intel compilers and MKL no longer valid due to changes in 0.6? Or have I just had a run of bad luck?

Building with Intel compilers is not something we have the infrastructure to test automatically, so it tends to be easy to break by accident.

Is it going to change according to this - ANN: The JuliaPro distribution by Julia Computing - #48 by RoyiAvital?

I know chances are slim and most chances it was about the Pro Version which costs money.
But better be optimistic :-).
