I have an old c++/python project that includes a python zip file "python27.zip". This zip file contains pyo optimized files.

I am trying to update python from 2.7 to the latest 3.7.1 (also updated the *.so lib file)

I did the next steps:

./configure --enable-shared --prefix=~/python-3.7.1/dist
make
sudo make install

I see that I have ~/python-3.7.1/dist/lib/python3.7 and it's structure is close to that I have in my old 2.7 zip.
Next I try to compile all the folder into pyo like:

python3.7 -O -m compileall .

It tells me that it requires Lib and Include (the headers) so I copied those 2 folders in that location too.

Doing python3.7 -O -m compileall . again inside dist/lib/python3.7 shows me

Listing './Lib/site-packages'...
Listing './Lib/sqlite3'...
....

and some errors like:

Compiling './Lib/test/badsyntax_future10.py'...
*** File "./Lib/test/badsyntax_future10.py", line 3
 from __future__ import print_function
 ^
SyntaxError: from __future__ imports must occur at the beginning of the file

I don't see any pyo's inside. Also if I try to do the same against 1 file, like python3.7 -O token.py (no errors) and also no pyo inside.

Don't judge me strict, I agree that I can be wrong in understanding this compilation process.

I had to create my own tool since I had not found anything suitable for the compilation of all python modules into one location/archive.

This PY_COMPILE_HELPER is available on the github. It was tested only from ubuntu.

With this module you can:

• Set input and output folder for the compilation


• Output source will have the same structure as the input source


• Set optimization level for binary files


• Skip or include test modules


• Compress compiled files into one archive


• Clean previously compiled files from the cache

Usage example:

$ ./py_compile_helper.py ./Python-3.7.1/Lib ./out -z -c -o2
