New submission from STINNER Victor:
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
haypo@speed-python$ ~/installed/3.7/bin/python3
