Building on macOS

[deajan]

I've tried to add support for darwin in d1ada6d
But this will be a long road, since I cannot test anything.

PS: What does python -c "import os; print(os.name)" output ?

posix

[deajan]

That's bad for me since I get the same output on Linux.
What does python -c "import sys; print(sys.platform)" say ?

I have cheated a bit and renamed restic_0.15.2_darwin_amd64 to restic_0.15.2_linux_amd64 - now compiling - it takes time as I do thin in VM

It was a bit dependencies fight and also question of using right python - you can't system one as:

FATAL: Error, on macOS, for standalone mode, Apple Python is not supported due to being tied to specific OS releases, use e.g. CPython instead which is available from https://www.python.org/downloads/macos/ for download. With that, your program will work on macOS 10.9 or higher.

So it is needed to install python via brew. Also some extra deps are needed.

When/if I succeed I will document it.

darwin

[deajan]

Thank you for the feedback.
I've updated in e09643c the darwin detection.
I'll happily update whatever will make MacOS compilation work ;)

Btw, does NPBackup work non compiled on MacOS ?

but as binary is in BUILDS/public/linux/x64/ I guess because I cheated with restic binary name.

Binary "works" but:

I guess it might be related.

Not sure I understand this question:)

[deajan]

You can just launch NPBackup without compiling it, ie python bin/npbackup. Does that work ?

I've updated in e09643c the darwin detection.

it now detects darwin restic binary correctly - let's see

Progress:

but when trying to run:

I do not worry about config part - it is not done. but why GUI disabled ???

And after more fight (does not help I know nothing about python) with python/tk dependencies and macOS peculiarities I can report that it is working (at least compiles and starts):

Thank you for your compile instructions - definitely it was game changer - at least for me.

[deajan]

I was going to give you the gui-status parameter for npbackup executable, which would have told you something like tcl/tk missing probably, but I see that you did succeed building ;)

Congratulations !!

Would you mind making a PR on the build instructions file ? Might be a saver for next MacOS guy ;)

[kapitainsky]

I will update COMPILE_INSTRUCTIONS.md - but first will have to repeat all steps again. I have some notes - but expect some mess I have to clean.

[kapitainsky]

one thing - could you please add darwin example config in examples? I guess the same as Linux - but it is something missing

Please use latest git master as compile.py might work without modifying restic binary names after latest commit

Like having the same file twice ?

I have used it - works fine.

[kapitainsky]

At the moment we have in examples:

npbackup.linux.conf.dist
npbackup.windows.conf.dist

we need to add:

npbackup.darwin.conf.dist

I guess it will be the same as linux one - have not looked into details yet.
