libass-0.13.7 not building on macOS 10.12.5 + Xcode 8.

[ssisak (Steve Sisak)]

libass is failing to build on current macOS+Xcode -- I'll update ticket as I figure it out, but here's the problem section of the log (missing dependency on libreadline)?

config.log from failure

[mf2k (Frank Schima)]

Duplicate #54321 has the fix.

[ssisak (Steve Sisak)]

The "fix" referenced is port upgrade redline...

I'm not sure that's correct as:

1. This was a part of "port upgrade outdated"
2. The error is that libreadline.6.dylib did not load
3. That appears to be because libreadline.7.dylib is what's currently installed

Not sure if I should address this here or in that ticket, but looks like a missing or circular dependency

[ssisak (Steve Sisak)]

Got it:

sudo port upgrade readline gawk

and then another

port upgrade outdated

Got things moving again -- assuming somethings missing a dependency on gawk.

[ssisak (Steve Sisak)]

Reading the other ticket, want to double check if someone (libass?) is missing a dependency on gawk

Pretty sure both ticked are reducing to gawk not being rebuilt automatically and failing because libreadline was too new.

Feel free to close again if I'm off base.

[Schamschula (Marius Schamschula)]

No such dependency.

If gawk is installed, it is found before the OS awk. Thus, if gawk is broken you will run into this issue on most ports that use ./configure.

[ssisak (Steve Sisak)]

Replying to Schamschula:

No such dependency.

If gawk is installed, it is found before the OS awk. Thus, if gawk is broken you will run into this issue on most ports that use ./configure.

OK, that's a better description -- maybe s/b FAQ

I only have ffmpeg and ImageMagick installed in MacPorts and this happened doing a "port upgrade outdated", meaning there's an implicit dependency on gawk somewhere -- or some port installs it as a side-effect causing it to override the system awk, which breaks some other port the is fine with the system awk (now being overridden) if it happens to build before whoever depends on gawk. HTH

In fact, this sequence where I followed the instructions but only built libreadine seems suddenly relevant:

--->  Updating database of binaries
--->  Scanning binaries for linking errors               
--->  Found 4 broken files, matching files to ports

You can always run 'port rev-upgrade' again to fix errors.
The following ports will be rebuilt: gawk @4.1.4+universal
