gmic-lib: Unable to upgrade on Mtn Lion - fatal error: use of undeclared identifier 'AT_FDCWD'

[RobK88]

I am unable to upgrade the port gmic from version 3.4.0. to version 3.4.1 on Mtn Lion.

I see the following error:

Sorry, I can't help you with Mountain Lion. I don't run any machines with non-current macOS versions, and thus can't test any fixes.

Hopefully, one of the fellow maintainers who works on backwards compatibility will chime in.

[kencu (Ken)]

that is covered by legacysupport, so step 1 might be to add that.

[RobK88]

Thanks Ken. I jave added the legacysupport port to this ticket. But I am unable to add any of the legacysupport maintainers to the cc list.

[kencu (Ken)]

the port already uses legacysupport I see, just have to change the blocker from this:

legacysupport.newest_darwin_requires_legacy 10

to this:

legacysupport.newest_darwin_requires_legacy 13

and give it a try.

[Ken <21211439+kencu@…>]

In 02b9b1ba06854d477a2f6476749f6327de25353f/macports-ports (master):

gmic: broaden use of legacysupport to darwin 13

closes: #70676

[kencu (Ken)]

I went ahead and did it for you.

let's see if that fixes this build error.

[kencu (Ken)]

link fails.

At first glance, it looks like the legacysupport library is not getting added.

Thanks Ken. Your change did help. The compile went further but then stopped with another undefined symbol error:

I have attached another main.log

[RobK88]

main.log after kencu changes

[RobK88]

@kencu I was mistaken. You were right. Your changes had no effect. It looks like the reason why the compile went further today for gmic-lib is due to updated dependencies. Both gobject-introspection and libsdl2 were updated. Now we have another undefined symbol - _faccessat

[kencu (Ken)]

oh, the build does get further, and the changes I made were needed.

Just not sufficient yet, as the legacysupport library is not being added to the link libraries.

Usually the legacysupport PG can automatically add it, but not working in this so someone will need to dig in and find out why not
