Installing librsvg fails with pango errors

works just fine for me here on macOS12 ....

are the rest of your ports up to date ? what does

Oberon ~/Projects/MacPorts/ports > port installed cairo pango
The following ports are currently installed:
  cairo @1.17.4_0+quartz+x11 (active)
  pango @1.48.10_0+quartz+x11 (active)

give you ?

[cjones051073 (Chris Jones)]

Also, try running these commands

Oberon ~/Projects/MacPorts/ports > pkg-config pangocairo --modversion
1.48.10
Oberon ~/Projects/MacPorts/ports > pkg-config pangoft2 --modversion
1.48.10

[breun (Nils Breunese)]

All my ports are updated, sudo port selfupdate && port outdated doesn't list any outdated ports.

Those commands show the same output on my machine:

~ ❯ port installed cairo pango
The following ports are currently installed:
  cairo @1.17.4_0+quartz (active)
  pango @1.48.10_0+quartz (active)
~ ❯ pkg-config pangocairo --modversion
1.48.10
~ ❯ pkg-config pangoft2 --modversion
1.48.10

But apparently the librsvg install finds Pango 1.42.4 instead of 1.48.10.

[breun (Nils Breunese)]

Replying to breun:

Those commands show similar output on my machine, but I don't have the x11 variants installed:

~ ❯ port installed cairo pango
The following ports are currently installed:
  cairo @1.17.4_0+quartz (active)
  pango @1.48.10_0+quartz (active)
~ ❯ pkg-config pangocairo --modversion

~ ❯ pkg-config pangoft2 --modversion

I don't understand how that can be possible since there should be no pango 1.42.4 on your disk for it to find.

Nils - Can you check to see if you have anything on your system user /usr/local that could be interfering here ?

[cjones051073 (Chris Jones)]

Just to note, none of the buildbots had an issue either with this update

​https://ports.macports.org/port/librsvg/builds/

Nils - You must have something installed that is interfering here....

[cjones051073 (Chris Jones)]

you also could try building under trace-mode ?

[breun (Nils Breunese)]

I have this issue on two machines.

When I tried to install the update with trace mode enabled this appeared in the output:

Warning: The following files inside the MacPorts prefix not installed by a port were accessed:
  /opt/local/lib/pkgconfig/pango.pc
  /opt/local/lib/pkgconfig/pangocairo.pc

The contents of these files indeed refer to version 1.42.4:

I don't know why these files are here, but according to MacPorts there are not installed by a port. Any ideas about why I would have these files? Should I just delete these files?

[cjones051073 (Chris Jones)]

Your installation is in a funny state, as those files are provided by a port, namely pango

  /opt/local/lib/pkgconfig/pangoft2.pc
  /opt/local/lib/pkgconfig/pangoot.pc
  /opt/local/lib/pkgconfig/pangoxft.pc

yes, at this point you need to resolve this by hand.

[breun (Nils Breunese)]

The pango port is not installed on my system:

❯ port contents pango                 
Port pango is not installed.

After removing /opt/local/lib/pkgconfig/pango.pc and /opt/local/lib/pkgconfig/pangocairo.pc the installation of librsvg wanted to install the Xft2 and pango ports. This failed because /opt/local/include/X11/Xft/Xft.h already exists and does not belong to a registered port. After a bunch more removing unowned files and forcing port activations I now have it working again. I do wonder how I got both of my machines into this state.

I guess this happened with the upgrade to macOS 12. I wonder if I have more files under /opt/local without a port that owns them. Do you happen to know if there is a way to check this for all files under /opt/local?

[cjones051073 (Chris Jones)]

librsvg declares a dependency on pango so unless you did something ill-advised, it should not be possible to have it installed without also having pango installed.

When you upgraded to macOS12 did you correctly follow the migration guide, to reinstall all your ports for the new OS ?

It does sound like your system is in a bit of a mess. At this point I would probably consider wiping it out and reinstalling from scratch.

Closing this, as it isn't a port bug.

[breun (Nils Breunese)]

It is possible to have librsvg installed without having pango installed, because librsvg depends on the presence of lib/pkgconfig/pango.pc (which I had on my system, but not the expected version), which the pango port as a fallback for when that file does not exist (​https://github.com/macports/macports-ports/blob/master/graphics/librsvg/Portfile#L26):

path:lib/pkgconfig/pango.pc:pango

If this was port:pango, then I would have probably found out sooner what was up.

But yes, it seems something funky happened on my MacPorts installations.

That's a good point, as the existence of lib/pkgconfig/pango.pc would theoretically satisfy the dependency.

@jmroot, can you confirm? And any other general thoughts on this ticket?

[cjones051073 (Chris Jones)]

Yes, I should have checked the dependency type librsvg was using, but a path style dep. like path:lib/pkgconfig/pango.pc:pango would explain how pango wasn't installed, if there was a zombie file left over for some reason that satisfied the path dependency, as I do not believe it is a requirement that the file satisfying it belongs to a port (for good reasons).

How Nils go into the state he was in on his system only he can really answer though.

I have from time to time run a "sanity check" on my /opt/local/lib and /opt/local/include folders, iterating over each file and running them through xargs to run a "port provides" on them, to make sure that no cruft has made it's way into those folders.

It is simple to do as a "one liner" manually in the terminal, but no doubt someone could run up a quick little shell script to do it too.

It would be great if such things became part of 'port diagnose' some day, along with a few other things of a similar nature that have come to mind over the years.

Would save people like Nils a lot of indigestion.
