can it produce a single-file "exe" now?

advantages / disadvantages compared to pyinstaller?

note: when trying it, pip install nuitka (into the virtual env, do not use the debian/ubuntu package).

nuitka 0.6.7 (installed via pip):

(borg-env) user@development:~/w/borg/src$ python -m nuitka --standalone --include-package=borg --show-progress --full-compat borg/__main__.py

After a while, there is a executable called __main__.dist/__main__ and when running it, it outputs:

@kayhayen any idea?

[kayhayen]

Note: Can can leave out the __main__.py as you can with Python, and it will produce a borg binary.

[kayhayen]

Regarding the __file__ attribute, there have been improvements in this area, I am almost sure, that opcode will have it on the develop branch, this has been added a couple of releases ago. I was unware that it affects distutils.

[kayhayen]

Regarding your question, single-file is for acceleration only.

[kayhayen]

And don't use --full-compat as it makes worse binaries (e.g. compatibly wrong line numbers), uses more compile time memory, and all the while solves no real problems. I am making the wording change from need not be used to should not be used.

The reason we have this, is so we can compare CPython output with Nuitka program output and expect identical output in all cases.

[ThomasWaldmann]

@kayhayen thanks for the hints! I'll try again with a future release.

[ThomasWaldmann]

A new nuitka release 0.6.8 is out since a while.
