[kencu (Ken)]

At this moment, I have no idea why you are seeing this. Or why you are building it, instead of installing a prebuilt binary, for that matter...

[murrayE]

Building the latest gcc5 seems to be initiated automatically by upgrading openmodelica-devel to its latest version.

[murrayE]

What exactly do you mean by "installing a prebuilt binary" in the case of gcc5?

[Schamschula (Marius Schamschula)]

The rebuild is due to a revision bump of gcc*, as mpfr was updated to version 4.0.1. Unfortunately the buildbot also fails to complete this build.

[kencu (Ken)]

Replying to murrayE:

What exactly do you mean by "installing a prebuilt binary" in the case of gcc5?

In almost all cases, when you install a port, you download a prebuilt binary that comes from Ryan's family of buildbots in Texas, you don't build it yourself.

In this case though, it looks like a recent mpfr update has made the port unbuildable. So there is no prebuilt binary of gcc5. Therefore MacPorts dutifully tries to build it for you on your system, and it fails.

Not sure where this will wind up. If you need to be up and running right now, peg mpfr in your local repo at the last version, and peg gcc5 at the last revision. Then all is well for the next few months until somebody sorts this out, if it can be sorted out.

[kencu (Ken)]

BTW, here's a current listing of which systems built gcc5 recently after the update:

<​http://packages.macports.org/gcc5/?C=M;O=D>

looks like most did. There are a few builds missing.

That is encouraging, as it would appear that whatever is wrong might be fixable.

[kencu (Ken)]

Looks like a known bug. See <​https://gcc.gnu.org/bugzilla/show_bug.cgi?id=83531>.

There is a workaround in that ticket, which I will explore...

patch for gcc5

[kencu (Ken)]

I have attached a patch that is supposed to fix this problem, courtesy of a smart guy at homebrew. It applies cleanly. gcc5 is building, and will take all night to finish.

I think it appears this has nothing to do with mpfr -- we just haven't revbumped gcc5 in quite a while, and so we didn't stumble across this until now.

[adavidzh (André David)]

cc me.

[kencu (Ken)]

Yep, that patch fixed the build. I'm not sure it's as elegant as it could be, and it looks to me like the error is really in Apple's header that should be fixed. But the patch worked.

[kencu (Ken)]

See <​https://github.com/macports/macports-ports/pull/1830>.

[ken-cunningham-webuse]

In 783216ed1e2475122420d02726c47da27f46292b/macports-ports (master):

gcc5: work around a bug in Apple's header on 10.13

closes: #56502

[murrayE]

’m still getting a long build that’s aborted with the error:

:info:build /System/Library/Frameworks/CoreFoundation.framework/Headers/CFBase.h:663:61: error: expected initializer before 'API_AVAILABLE’

• Should the version still be gcc5 @5.5.0_1?

• Is there an issue of delay in getting the patched version posted in the macports repository?

[kencu (Ken)]

you could check and see if you have the patch:

$ ls -la /opt/local/var/macports/sources/rsync.macports.org/release/tarballs/ports/lang/gcc5/files

if you see this file, you have the patch:

headers-10.13-fix.patch

[kencu (Ken)]

And the buildbot finished it now <​https://build.macports.org/builders/ports-10.13_x86_64-builder/builds/26648/steps/install-port/logs/stdio> so that should be the end of all the heartburn.

[murrayE]

The patched pre-built version is now being installed almost instantaneously. (The headers-10.13-fix.patch was there.) Thanks to all.
