| I'm trying to compile Python 3.6 from source on MacOS X Sierra. However it seems that the _ssl module doesn't get built. Attached is the complete output. Note that I have openssl installed via homebrew: ~/ ▸ brew list openssl /usr/local/Cellar/openssl/1.0.2j/bin/c_rehash /usr/local/Cellar/openssl/1.0.2j/bin/openssl /usr/local/Cellar/openssl/1.0.2j/include/openssl/ (75 files) /usr/local/Cellar/openssl/1.0.2j/lib/libcrypto.1.0.0.dylib /usr/local/Cellar/openssl/1.0.2j/lib/libssl.1.0.0.dylib /usr/local/Cellar/openssl/1.0.2j/lib/engines/ (12 files) /usr/local/Cellar/openssl/1.0.2j/lib/pkgconfig/ (3 files) /usr/local/Cellar/openssl/1.0.2j/lib/ (4 other files) /usr/local/Cellar/openssl/1.0.2j/share/man/ (1592 files) but if I understood Mac/BuildScript/resources/ReadMe.rtf correctly, this should be irrelevant. Anyway the resulting pip seems to be unusable: ~/ ▸ python -mpip install cx_Oracle pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available. Collecting cx_Oracle Could not fetch URL https://pypi.python.org/simple/cx-oracle/: There was a problem confirming the ssl certificate: Can't connect to HTTPS URL because the SSL module is not available. - skipping |

| Did you set CFLAGS and LDFLAGS? |

| No, neither CFLAGS nor LDFLAGS are set, the only "FLAGS" environment variable I have set is ARCHFLAGS='-arch x86_64' (I can't remember why). However unsetting this variable doesn't change the result. |

| Ah, things are quite the opposite :) You have to set CFLAGS and LDFLAGS so that setup.py can find openssl headers and libraries from Homebrew. For example: export CFLAGS="-I/usr/local/opt/openssl/include" export LDFLAGS="-L/usr/local/opt/openssl/lib" The reason for that is that Apple once shipped their forked OpenSSL in older Mac OS X versions, so Homebrew can't install OpenSSL headers and libraries to public paths (/usr/local/include & /usr/local/lib). On the other hand, CPython should not use paths in /usr/local/opt/ as it's internal details of Homebrew. |

| OK, I've set CFLAGS and LDFLAGS as you suggested. However the ssl module still doesn't get built. Attached is the new build log (Python3.6-build2.log) |

| Change this line: export CFLAGS="-I/usr/local/Cellar/openssl/1.0.2j/include/openssl" into: export CFLAGS="-I/usr/local/Cellar/openssl/1.0.2j/include" |

| OK, with the fixed CFLAGS definition I do indeed get a working ssl module. I wonder whether the link Ned posted should be put into the README file. Anyway I think the issue can be closed. Thanks for the help! |

| I have the same problem as described here. How can I install Python3.6 and pip without sudo and without homebrew? I get the same error message after installation: pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available. |

| @Tommy.Carstensen: Unfortunately, Apple has deprecated use of the system-supplied OpenSSL libraries and with the latest releases no longer supply the header files needed to build with them. They are very old anyway. So, you need to supply a version of them. The easiest way is to get them from a third-party package manager like Homebrew or MacPorts but you certainly can download an OpenSSL source release from https://www.openssl.org and build the libraries themselves. If you do not have administrator access, you will probably need to modify the OpenSSL build using at least --prefix to install to a non-system location and then rerun Python's ./configure with CFLAGS and LDFLAGS pointing to the installed location of your OpenSSL. |

| Thanks @ned.deily ! That did the trick for me! When installing openssl I just had to do ./config --prefix=/my/home/dir prior to doing make and make install. Then I just did two commands prior to installing python3.6: export CFLAGS="-I/my/home/dir/include" export LDFLAGS="-L/my/home/dir/lib" |

| The problem with compiling OpenSSL from source is that it doesn't know how to access the root certificates needed for verification on Mac OS X. See for more details. |
