Hi Team,
I met the issue consistently on 3.7 and 3.7.1.

The configure is well, but when the make will output error messges:

step1: [ok]
sudo ./configure --prefix=/opt/python3.71 --enable-optimizations

step2: make [fail]

if test $? -ne 0 ; then \
	echo "generate-posix-vars failed" ; \
	rm -f ./pybuilddir.txt ; \
	exit 1 ; \
fi

Any questions pls mail me.

Thanks for the report. Is this related using older version of GCC? Searching the bug tracker tells me a related issue (https://bugs.python.org/issue34112) where --enable-optimizations caused build error on 3.7.0 for older compiler toolchain like GCC 4 with a very similar traceback.

• Can you please upgrading GCC and try?
• Does the build also fails without --enable-optimizations flag with your current version of GCC?

[foxleoly]

I've tested 2 way to solve this:

1. disable --enable-optimizations option. the software can be compile and install successful.
2. upgrade gcc version to 8.2.0.

docker ➜ bin gcc --version
gcc (Debian 8.2.0-8) 8.2.0

Thanks, I guess then it's the same as bpo-34112 with --enable-optimizations being incompatible with older compiler toolchains like GCC 4 in this case. Feel free to close this if it resolves the issue.

[foxleoly]

Sure! Yes, Pls close it.

[tirkarthi]

Sure, I am closing it with duplicate as resolution adding the related ticket bpo-34112 as superseder. Thanks for the report!
