Mac OS X: cp: illegal option -- u

[hughperkins]

On Mac OS X, branch 'master':

When I do:

git clone https://libfuse/sshfs
cd sshfs
mkdir build
cd build
meson ..
ninja

What I expect to happen:

build finished ok

What actually happens:

(root) ~/git-local/sshfs/build (master|…1) $ ninja
[1/3] Generating test_scripts with a custom command.
FAILED: test/conftest.py test/pytest.ini test/test_sshfs.py test/util.py 
cp -fPu --preserve=mode ../test/conftest.py ../test/pytest.ini ../test/test_sshfs.py ../test/util.py /Users/hugh2/git-local/sshfs/build/test
cp: illegal option -- u

Thanks for the report! GNU cp has a -u flag that means:

       -u, --update
              copy only when the SOURCE file is newer than the destination file or when the
              destination file is missing

Could you check if MacOS' cp has something similar?

[hughperkins]

Doesnt appear to. So you should always copy on mac perhaps. or use python perhaps.

[hughperkins]

why closed?

[hughperkins]

ah I see. you closed via a commit. cool :-) Thanks! :-)

Hey man, sorry to say that due to this + libfuse/libfuse#204 , you are stuck between a rock and a hard place if you try to from-scratch install sshfs on OSX.

1. We are forced to use 2.x because no fuse3

2. We don't have the commit that fixes this issue (ninja doesn't run.)

Will report back if this prevents actual usage, instead of just testing.

[Nikratio]

I don't understand. If you have to use sshfs 2.x, and can't use Ninja/Meson, then you shouldn't see this problem in the first place (because it exists only in the Meson configuration).

I had the same issue and keep getting the error @hughperkins posted when i run the ninja command. I tried using sshfs 2.x, but still get this error, but I'm using meson and ninja. If I shouldn't use ninja/meson, how should i install, because the instructions to install only provide a method using those packages.

[Nikratio]

Take a look at the instructions that come in the SSHFS 2.x tarball.

command: ['cp', '-fP', '--preserve=mode',
                        '@INPUT@', meson.current_build_dir() ]

--preserve=mode
Yes, works for linux. For BSD : no go. Suggest that the following parameter should be used for BSD / OSX :
-fp . Please note that this is the small letter p ( p for papa ). The --preserve=mode was not working for me under OSX / BSD, so i removed it. Before edit : the compile would not run. After edit : The compile would run.
