hexchat: build failure on <10.10

[Ionic (Mihai Moldovan)]

The default-enabled sysinfo plugin uses an API that is only available on 10.10+ for getting the fine-grained OS X version number.

We'll need to patch this around to support older releases as well.

This goes after #52384.

Just for review, if this looks good to you, I can commit it myself.

The suggested patch has already been merged upstream, c.f. ​Hexchat Github PR #1821.

that's weird.

I installed this on 10.4 Tiger (of all things) a few weeks ago. @2.10.2_2 +ssl without any modifications.

It works fine.

[Ionic (Mihai Moldovan)]

This is for 2.12.1. :)

hexchat was updated recently. 2.10.2 is not affected by that problem yet.

[ken-cunningham-webuse]

aha. thanks. That's what I love about MacPorts. Problems get fixed before I even knew they were there. Magic.

[Ionic (Mihai Moldovan)]

Just looked it up. More specifically, that version was also affected, BUT the sysinfo plugin wasn't built on OS X by default in 2.10.2, but only if libpci 3.0.0 or higher was installed (which probably could be classified as a bug and was later changed.)

2.12.0 explicitly enabled it if OS X is detected or libpci 3.0.0 or higher is installed.

To simplifiy this, we could use ​operatingSystemVersionString (available on OS X >= 10.2). The only difference seems to be that this would also include the build number, but this is only the fallback anyway.

[raimue (Rainer Müller)]

Fixed in r153195.

[Ionic (Mihai Moldovan)]

operatingSystemVersionString is probably the better route to go, because it's not deprecated and in the end we want a human-readable string anyway. We'd have to convert it to a C string and put it under our control, though.

Hi ,

The patch gets applied, but unfortunately doesn't fix the build on 10.6. It appears that the availability guard is not working correctly on this system at least.

[ken-cunningham-webuse]

this comment was just wrong, and I deleted it.

[Ionic (Mihai Moldovan)]

I think the problem is the MAC_OS_X_VERSION_10_9 macro, which is not defined on your OS.

Can you change MAC_OS_X_VERSION_10_9 to 1090 in the patchfile, clean and retry to upgrade hexchat? If that works, that's the best I will be able to do...

[ken-cunningham-webuse]

That fixed it. Thanks. K
