Unable to build Python on macOS Big Sur with Xcode 12 beta #1643
Comments
|
It doesn't build with Xcode 11.5 either. |
|
@bjackson on macOS Catalina or the Big Sur beta? |
|
Big Sur beta |
|
Same here - Big Sur beta, Xcode 12. pyenv install 3.8.3 fails as above. Tried setting SDKROOT to 10.15 and 10.16, neither was successful. ./configure && make are successful (with cpython source from python.og) but the readline module does not get built. Wonder if this might have to do with readline?? (Def not an expert ;-) Will update if I get it working. |
|
So, still struggling with pyenv on BIg Sur (obv not a pressing issue for me). However, to add to this thread, I attempted to install python from homebrew. With:
I got the following error: I tried to install vanilla python from homebrew (sans --HEAD) and homebrew python installed without error. I really think (since homebrew install with --HEAD option and pyenv install both try to install from source, and both fail with readline error messages) there might be an issue with the readline module and Big Sur. I don't have the technical skills to absolutely determine this, but it is fishy. Wondering, @Sjors , if you are able to install python via homebrew (first attempt with --HEAD) and then attempt without --HEAD. |
|
I tried the homebrew binary back then and it worked. IIRC having Homebrew build from source resulted in the same problem as PyEnv had. We should probably keep an eye on Homebrew/brew#7857 |
|
I added |
|
@palmerc , I'm showing my ignorance here. How to you add |
No ignorance - this is obviously me hacking until I could get it to compile. Yes, you'll have to apply a patch to the source after it is installed. I'm not suggesting this is a legitimate solution, simply that the problem is related to the _POSIX_C_SOURCE #define. What I did to get python on my beta build machine was to build it on a Catalina machine with Xcode 11 and then copy the whole |

I am also facing similar issue with

@PritamDutt , thank you. When I tried 3.8.3, again, pasting your script above: Checked homebrew, and it is installed, but not linked. Had no effect. I removed 3.8.3 and reattempted and got the same warning. At least, I have python installed on Big Sur via pyenv. |
|
It took a while to get "pyenv install ..." to work under macOS Big Sur with Xcode 12 beta, but I have now build 3.8.3, 3.8-dev, 3.9.0b4 and 3.9-dev. I have also been able to build python via home-brew (i.e. brew install python@3.8) Here is the relevant sections I have added to my ~/.zshrc and ~/.bash_profile: # HOMEBREW Environment Variables export PATH="$HOMEBREW_PREFIX/opt/tcl-tk/bin:$PATH" # Use PyEnv to set Python Environment # PyEnv & HOMEBREW Build variables if command -v pyenv 1>/dev/null 2>&1; then |

==> Caveats
bzip2 is keg-only, which means it was not symlinked into /usr/local,
because macOS already provides this software and installing another version in
parallel can cause all kinds of trouble.
If you need to have bzip2 first in your PATH run:
echo 'export PATH="/usr/local/opt/bzip2/bin:$PATH"' >> ~/.zshrc
For compilers to find bzip2 you may need to set:
export LDFLAGS="-L/usr/local/opt/bzip2/lib"

I saw something somewhere on make/cmake having issues under Big Sur & Xcode 12, so I did do a homebrew reinstall from source: FYI: I was just able to install Python 3.8.4 with my configuration (i.e. "pyenv install 3.8.4") under MacOS 11 & Xcode 12. And with home-brew's 3.8.4 roll out (via python@3.8), that build successfully as well. If you could not tell from my ~/.zshrc above, I have installed the following key homebrew components before building python via "pyenv install ...":
Also, while not having the following installed (and added to my ~/.zshrc) did not produce an error; output from the compile indicated the following could not be found, so support for them was not included in the python build:
So if you need support for those, you will need to install them and add the to the ~/.zshrc. |

I was shown the available update yesterday, to beta 8, but I haven't gotten the chance to update yet. Would you mind reporting what your By the way, the script is originally from @rdbreak, so give his a shot as well and see if it helps. |
I've given @rdbreak 's script a try as well but to no avail. I have all the dependencies from brew. Here is my clang version I can run 3.7.x or higher without issue but this is just to notify anyone using versions 3.6.x |
Updated to beta 8. Updating SDK to Command Line Tools for Xcode 12.2 beta 2 and running fixed my issues. |

@baspeti It looks like you’ve brew installed your pyenv? On an M1 I had much more success when pyenv was installed with the pyenv installer. With brew, i had to force the arch (as youve done) with almost everything brew related. I’d encourage you to try https://github.com/pyenv/pyenv-installer but, I’m aware that things move fast and brew may be better with M1 now (or very soon) |

And everything seems to be working just fine. For anyone like me who is also just learning about what So if you install brew natively, then pyenv with brew, then Python 3 with pyenv, it should all work fine 👍 |

My environment:MacBook Pro 2019, i7 Thank you, that finally made it possible for me to install Python 3.8.9 without any additional flags or scripts (although installing packages suggested in the thread could have helped). Unfortunately I still cannot install Python 3.6.4, which would be useful for older projects in my company. I tried every suggestion in the thread with different patching, flags, etc. but I'm still getting: `BUILD FAILED (OS X 13.1 using python-build 20180424) Inspect or clean up the working tree at /var/folders/zh/_kmwgbrx5gx5jry3mqnw_xyw0000gn/T/python-build.20230116135504.38123 Last 10 log lines: By default, distutils will build C++ extension modules with "clang++". checking for the platform triplet based on compiler characteristics... darwin |

I installed macOS Big Sur beta 1, Xcode 12.0 beta (12A6159) on an old Mac to see what breaks. I'm able to install PyEnv via Homebrew, but I'm not able to build any Python version.
Apple clang version 12.0.0
pyenv_install.log
Note that
MacOSX.sdkis symlinked toMacOSX10.16.sdk. Pointing the symlink to MacOSX10.15.sdk doesn't help.I didn't try switching to Xcode 11 yet, though that will probably help, if it's indeed a clang problem.
Downloading and installing Python 3.8.3 from the website works fine (python3 executable).
