Hi,

I compiled Python 3.7 using PGO+LTO with "make && make install", but it seems like it lacks the _sysconfigdata module.


Moreover, I don't see any "Makefile" file in the installed directory, so the "~/installed/3.7/bin/python3  -S -m sysconfig --generate-posix-vars" command fails on trying to import _sysconfigdata_m_linux_x86_64-linux-gnu ...                  

$ find /home/haypo/installed/3.7 -name "Makefile"
<nothing>

Is it correct to use "make && make install" using PGO?

cd ~/cpython
make distclean ||:
./configure --enable-optimizations --with-lto --prefix=/home/haypo/installed/3.7
make clean
make
make install
