Hi, I use macOS Catalina 10.15. I use Xcode 10 and Xcode 11, but with that configuration, compiling Python 3.7.14 does not work for me. Any idea whats causing this issue?

configure: error: could not find pthreads on your system
user@Users-MacBook-Pro Python-3.7.4 %

When building a default 64-bit-only Python on current MacOS systems, don't use the --enable-universalsdk (and --with-universal-arch) options to ./configure since system header files are no longer installed in /usr/include.

Be aware that you may have to supply some third-party libraries which are no longer or have never been shipped by Apple with macOS, most notably OpenSSL libraries and libzma.  The Python Developer's Guide gives some help on how to use versions of these libraries from third-party disrbutors Homebrew or MacPorts.

https://devguide.python.org/setup/#macos-and-os-x

Also suggest you first try building and installing without using --enable-optimizations as that option greatly lengthens and complicates the build process.

And you probably want to change --with-framework-name to python37 if you continue to use it.

The Python build information for current macOS systems is somewhat out-of-date; it should be getting updated in the next few weeks.

Under OSX 10.15 beta and Xcode 11.0 beta the following does not work:
./configure --enable-framework

DYLD_FRAMEWORK_PATH=/Users/bill/cpython ./python.exe -E -S -m sysconfig --generate-posix-vars ;\
	if test $? -ne 0 ; then \
		echo "generate-posix-vars failed" ; \
		rm -f ./pybuilddir.txt ; \
		exit 1 ; \
	fi
/bin/sh: line 1: 78734 Segmentation fault: 11  DYLD_FRAMEWORK_PATH=/Users/bill/cpython ./python.exe -E -S -m sysconfig --generate-posix-vars
generate-posix-vars failed

The following seems to work:
./configure --disable-framework

My guess is that this is an Xcode 11 beta issue.

#38295 gives error reports for test_py_compile with 3.8, which implies that Python was compiled well enough to run and fail a test.

Isn’t https://bugzilla.suse.com/1152793 (removal of stropts.h from glibc) cause of this?

Sorry, got confused. My openSUSE bug has nothing to do with it.

Going back and looking closer at the original failure, I see now that the root cause of the configure failures *is* using --with-universal-archs=64-bit.  As noted in the Mac/README file, "64-bit" means compile for both "ppc64" and "x86_64" architectures; the configure tests fail because the Apple-supplied build tools (via Xcode or the Command Line Tools) have not supported either ppc or ppc64 for many years (since 10.7, I believe).  In more recent releases prior to macOS 10.15 Catalina, macOS still supported running programs in either intel-32 (i386) or intel-64 (x86_64) so there was still some use for --with-universal-archs=intel, which compiles for both x64_64 and i386.  But 10.15 Catalina no longer includes 32-bit libraries and frameworks, so it is not possible to run 32-bit executables natively anymore.  Thus the only architecture option that is of use on 10.15 is the default, x86_64.  So my original suggestion, to remove the --enable-universalsdk and --with-universal-arch options from your ./configure command should solve the problems you are seeing.  I also verified that --enable-optimizations without --wiht-universal-arch and --enable-universalsdk resulted in a successful build (after following the Devguide's recommendations to install missing libraries using Homebrew).

That said, ./configure should be less cryptic about these kinds of problems.  I've opened Issue38443 to suggest that ./configure be enhanced to give better error messages when a CPU arch is not available to build.

I was unable to reproduce the different failure reported by Bill Minasian in msg351312.  If that problem can be reproduced with the stable release of 10.15 and Xcode 11, please open a new issue for it with details on how to reproduce.

The crash reported by BMinas is reputedly related to the -fstack-check option, which is said to be on by default when MACOSX_DEPLOYMENT_TARGET=10.15. I've been unable to confirm whether there was just a bug in the beta, or if it's still a problem on the final Catalina release.

Thanks for the input, @jmr!  I realize that what I wrote was ambiguous so to clarify I *have* tested that example with the final release versions of Catalina and Xcode 11.1 and could not reproduce.  Just for fun, I've also tested with the latest developer previews of 10.15.1 and 11.2 with and without adding -fstack-check via 'OPT=' again without failure.  (Not being familiar with the stack-check option, I don't know if just adding it to the compiler command lines is sufficient.)  So if anyone *can* reproduce with current releases, please open a new issue about it.
