Build Python 3.7 with Intel compilers on CentOS 7

[Sas_González__Borja]

Hi.

I'm trying to build Python 3.7 on CentOS 7 with Intel compilers. I'm using version 2018 of the compiler.

To compile I do the following:

export CC=icc
export CXX=icpc
export FC=ifort

./configure --prefix=my_prefix --enable-optimizations --without-gcc
make
make install

In the configure, no error is seen, but when I execute make, the following message is printed:

Running code to generate profile data (this can take a while):
# First, we need to create a clean build with profile generation
# enabled.
make profile-gen-stamp

      atomic_uintptr_t _value;
      ^

I have searched but I can not find the solution to the error. Any ideas?

Can you try the 2019 update 4 version?

[Sas_González__Borja]

No. I do not know if I can have the version you told me. Still, would a new version fix the error?

I don't know if this will help. But give it a try: https://blog.semicolonsoftware.de/compiling-python-numpy-and-scipy-with-intel-compilers-and-intel-mkl/ 

btw. using the latest compiler is always a good idea. you can download an eval copy to start with. 

Thanks,

I confirm that the problem exists with 2019 update 4...

And following the blog.semicolonsoftware.de link also leads to the same error.

Can you create a preprocessed file for python.c.

I am having the same problem trying to compile python 3.7.4. Is there a solution? For me the make process fails quite early:

icc -pthread -c -Wsign-compare -Wunreachable-code -DNDEBUG -g  -O3 -Wall    -std=c99 -Wextra -Wno-unused-parameter -Wno-missing-field-initializers -Wno-cast-function-type -Werror=implicit-function-declaration -fp-model strict -prof-gen  -I. -I./Include -I/discover/nobackup/projects/tm5var4d/packages/openssl/1.1.0h/include -I/discover/nobackup/projects/tm5var4d/packages/python3_prereqs/include  -fPIC -DPy_BUILD_CORE -o Programs/python.o ./Programs/python.c

Can you provide us preprocessed file (by replacing -c with -E)? Make sure you are still able to compile the preprocessed file and see the same error by replacing python.c with python.i.
