--->  Computing dependencies for samba4
Error: Can't install samba4 because conflicting ports are active: samba3
Error: Problem while installing samba4
Error: Follow https://guide.macports.org/#project.tickets if you believe there is a bug.

This is not a bug per se, as samba3 and samba4 cannot currently be installed at the same time. (Though I plan to fix that, eventually.)

Can you check whether any installed ports require the former, via port dependents samba3?

[jpmelko]

titi@Bacchus ~ % port dependents samba3
MPlayer depends on samba3
ffmpeg depends on samba3

Replying to jpmelko:

titi@Bacchus ~ % port dependents samba3
MPlayer depends on samba3
ffmpeg depends on samba3

Thanks for confirming. I'll add a variant to allow the use of samba3, for folks who need/want it. (Thankfully ffmpeg works with both.)

ffmpeg/ffmpeg-devel: add variant samba3

• Since 'samba3' and 'samba4' can't co-exist yet, allow users to override default

Fixes: #64890

[mascguy (Christopher Nielsen)]

This change should be available after two hours have passed.

At that point, resync your ports via sudo port selfupdate. And then install via sudo port -N install ffmpeg +gpl3 +samba3.

And let me know if all is well after the update!

all works fine

Great, glad we were able to resolve your issue!

[mouse07410 (Mouse)]

Well, I think I resolved this issue in a simpler/better way:

$ sudo port -f deactivate samba3
$ sudo port upgrade ffmpeg
$ sudo port uninstall inactive

After this, samba3 is replaced with samba4, which is probably for the better. ;-)

Note that neither ffmpeg nor Mplayer ports list samba (either 3 or 4) as a dependency - either build or library dependency:

$ port info Mplayer
MPlayer @1.3.0_8 (multimedia)
Variants:             a52, aa, caca, debug, dirac, dts, dv, esd, faac, fribidi, glx, lirc, live, man_all_lang, mencoder_extras, mng,

Replying to mouse07410:

Bear in mind that Samba comes into play when ffmpeg is installed with variant +gpl3. As for mplayer, that occurs when variant +smb is selected.

So, you'll need to enable the appropriate variant when checking a port, to see the dependency.

In any case, relative to a better fix, we might be able to switch to a path-style dep for Samba everywhere. But I'll first need to test the other dependents, to see whether Samba 4 works elsewhere too.

In the interim, I'll update ffmpeg to do so, and eliminate the samba3 variant.

ffmpeg/ffmpeg-devel: use path dep for samba3; remove variant samba3

• Port works with both 'samba3' and 'samba4', allowing user to install either
• Also switch back to 'samba3' as the default, to minimize user pain
