Problem installing Planck likelihood

[Mastache, Jorge]

I have a problem installing the Planck likelihood in a Mac, the problem is the following:

After having a successful configuration

Code: Select all

> ./waf configure --lapack_mkl=/opt/intel/mkl --install_all_deps

here I have a couple of warnings:

Code: Select all

Checking for program 'gcc, cc'           : /usr/bin/gcc 
gcc not found(cause : Could not find g++, if renamed try eg: CXX=g++48 waf configure
(complete log in /Users/Jorge/Dropbox/Programacion/Cosmomc/plc-2.0/build/config.log)) 
Checking for program 'icc, ICL'          : not found 
icc not found (cause : Could not find the program ['icc', 'ICL']
(complete log in /Users/Jorge/Dropbox/Programacion/Cosmomc/plc-2.0/build/config.log)) 
Checking for program 'clang'             : /usr/bin/clang 

Then I run

Code: Select all

> ./waf install

and I get the error:

Code: Select all

clang: error: unsupported option '-fopenmp'

Now, the problem is that clang doesn't support openmp, I followed this instructions to install llvm, but it didn't work with clang.

Now, the problem I thing is that in the configuration waf doesn't recognize that I have install gcc, for instance:

Code: Select all

> gcc --version
Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/usr/include/c++/4.2.1
Apple LLVM version 8.1.0 (clang-802.0.42)
Target: x86_64-apple-darwin16.6.0
Thread model: posix
InstalledDir: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin

I even have installed:
> gcc-5
> g++

and with those I have openmp

Can anyone knows how to deal with this problem?

Thanks in advance!

It seems to me you have the intel composer suite, since you direct the --lapack_mkl=... flag to /opt/intel/mkl

It also occurs to me that you computer does not find you icc compiler.
So try sourcing the compilervars.sh file.

It usually could be found in /opt/intel/bin folder, but maybe for Mac it's different.

if you insist on using gcc then all you need to do is provide a flag like so:
CC=gcc
or, if the global is not recognized -
CC=/Path/to/gcc

You also need your gcc and fortran versions to be compatible so you might also provide:
FC=/path/to/gfortran

Lastly, I am not sure whether intel MKL is compatible with gcc and gfortran, so you might consider a different linear algebra pack...

Thanks for your answer Ira, it give a clue of what to do.
I didn't have installed icc, but I do have gcc (by default) I also installed gcc-5 and I have clang.

So, I solve the problem by using clang-omp (installed with llvm) instead of just clang, and by the way, when I tried to use any other gcc I get an error related with python flags.

I use:

Code: Select all

> ./waf clean
> ./waf configure CC=/usr/local/bin/clang-omp --install_all_deps --lapack_mkl=/opt/intel/mkl
> ./waf install

and this give no errors.

Thanks!

Hi Mr.Mastache

A similar situation came to me.

When I am trying to configure the plc-3.1,
after inputing "./waf configure --lapack_mkl=${MKLROOT} --install_all_deps",
it shows:

Code: Select all

> Checking for program 'gcc, cc'           : /usr/local/bin/clang-omp 
> gcc not found(cause : Could not find gcc/g++ (only Clang), if renamed try eg: CC=gcc48 CXX=g++48 waf configure
> Checking for program 'icc, ICL'          : /usr/local/bin/clang-omp 
> icc not found (cause : Not icc/icpc)

I have followed https://stackoverflow.com/questions/38971394/brew-install-clang-omp-not-working(clang-omp),
and use:

Code: Select all

> ./waf configure CC=/usr/local/bin/clang-omp --install_all_deps --lapack_mkl=${MKLROOT}

but it won't help.

Do you have any ideas to solve this problem?

Thanks in advanced.
