I tried to install python3.6.4 on OSX 10.13.2.  I followed the Build Instructions in the README.rst:

    ./configure
    make
    make test
    sudo make install

After ./configure step, the end of the output said:

---
If you want a release build with all stable optimizations active (PGO, etc),
please run ./configure --enable-optimizations
---

So I did:

~/Downloads/Python-3.6.4$ ./configure --enable-optimizations

Next, I did:

~/Downloads/Python-3.6.4$ make

But the make step always hangs on the line:
       
      ...
      ...
      0:00:18 load avg: 2.10 [ 23/406] test_asyncgen
      0:00:19 load avg: 2.10 [ 24/406] test_asynchat
      0:00:21 load avg: 2.01 [ 25/406] test_asyncio


During the make step, OSX prompts me whether to allow incoming connections.  I've tried it both ways: Deny and Allow, but the install allows hangs on the test_asyncio line.  I hit Ctrl+C to quit the install.  One time, I waited over an hour and the install was still hanging.

Oh, yeah, I'm using Python-3.6.4.tgz for the install.

My os is OSX 10.13.2

That sounds like the problem documented in Issue32517.  As a temporary workaround, try building without using --enable-optimazations.

Hi Ned Deily,

Thanks for the suggestion.  I ran ./configure again, but this time make errored out:


...
...
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make: *** [python.exe] Error 1

So I deleted the Python3.6.4 directory:

$ rm -rf Python-3.6.4

and I started over:

~/Downloads$ tar xfvz Python-3.6.4.tgz 

Then I ran ./configure, then make, and this time make completed successfully.

However....next up was make test, and after letting make test run for two hours, I killed it:

So, it looks like the same problem. :(

Sorry, I wasn't clear but, yes, you will run into the same problem if you try to run the test suite with test_asyncio.  There are various ways to exclude specific tests (not particularly well-documented), one way is:

make test EXTRATESTOPTS='-x test_asyncio'

But, that said, building Python on current versions of macOS can be problematic in that Apple doesn't ship or, in the case of OpenSSL no longer ships, all of the third-party libraries and header files needed for a fully-functioning Python installation.  The Python Developer's Guide touches on this here:

https://devguide.python.org/setup/#build-dependencies

Depending on what you want to do with Python, you *might* be better off installing a pre-built one rather than trying to build it yourself.  Versions of Python 3.6.x for macOS 10.13 are available from https://www.python.org/downloads/ and from a number of third-party distributors like Homebrew, MacPorts, and others.  Good luck!

Thanks for getting back to me Ned!  I'll just install a pre-built python, then. In the past, I've always installed python via a .tgz file, so out of habit that is what I tried first.

A followup: a fix for the hang in test_asyncio has been released in 3.6.5rc1.
