so many that probably are a cascade of issues
I include the man.log
this is trying to build with latest Xcode 11 (not. a beta) on Mojave (so no NDA issues)

No maintainer listed

[vdoublie]

gzipped main.log

[vdoublie]

the errors listed after the "liine 449" are caused by this first problem.
disabling "use_parallel" in the Portfile allows to disentangle to problem.

[kencu (Ken)]

nothing related to gcc can presently build against the xcode11 10.15 headers.

see many other open tickets. gcc is working on it. Only reliable option is to go back to Xcode10 until it gets sorted out.

[vdoublie]

it finally got to build on a Mojave Xcode 11.0 and Xcode 11.1

[mouse07410 (Mouse)]

It would be awfully nice if in addition to "I (finally) got 'it' working" (whatever 'it' might be) people would spare a few words on how.

E.g., following one of the advices given where? Another MacPorts ticket? Which one?

[kencu (Ken)]

Chris added a patch that should fix building gcc9 against the 10.15 SDK. So it should "just work" now.

All other gcc versions remain broken, however, building against that SDK.

[ogourgue (Olivier Gourgue)]

I don't see any upgrade of gcc9 when doing a selfupdate. What is this patch you are talking about?

[kencu (Ken)]

[368383b4263282656853b68965c3db455333c5bd/macports-ports]

You won't see a version update. But failing builds against the 10.15 SDK should now work.

[vdoublie]

uh tried ti install gcc9 on macOS 10.15 Xcode 11.1 (user release) and I get a series of errors will join the log file. This errors I saw on 10.14 + Xcode 11 Betas. Now gcc9 builds on 10.14+Xcode 11.1 but still not on Catalina Xcode 11.1 see main.log

[vdoublie]

Catalina build failing with very same error as prior Mojave + Xcode beta builds

[kencu (Ken)]

that must be frustrating! I upgraded one of my systems to Catalina today, somI'll run a build myself shortly.

[vdoublie]

Yup very. there are only. a few major port that I need to run and it is the first time I am stomped by libgcc. Most of the port sI found not building had an easy "hack" like removing the use_parallel=yes or adding use_parallel=no in the Portfile, or forcing a OSX_TARGET ... but I am not expert enough to figure out the behaviour of libgcc errors (at least it stopped fault segmenting ;) )

Have you resolved your issue yet? My log file looks exactly the same when trying to install gcc9

The latest log attached to this still has

which leads me to suspect you in fact have not updated to get the patch that fixes this. Please run

sudo port sync
sudo port upgrade outdated

and then try again with a clean build attempt.

[cjones051073 (Chris Jones)]

one other comment. The build log is for gcc9, which means libgcc9 must have built OK. Both share the same build, so if libgcc9 worked gcc9 has to as well, unless you have not cleaned you build before trying. so also do

sudo port clean gcc9 libgcc9

then try again.

Usually I get past that error with -Wl,-no_compact_unwind, but I'm not sure why you're seeing it whereas others don't seem to be seeing it.

Do you have the wrong ld64 installed? The only version that works correctly is ld64 +ld64_xcode (ie "no MacPorts ld64" but that's another tale...).

I agree with ken. Check the toolkit you have installed.i.e.

sudo port sync
sudo port -f uninstall ld64 
sudo port -f uninstall cctools
sudo port install cctools

then you should have the current defaults, which should work OK. (removing cctools might not really be needed, but does no harm...)

[thesamirsim]

Thank you. That's right, the problem was actually at the ld64. the following commands have solved the problem

sudo port sync
sudo port -f uninstall ld64 
sudo port -f uninstall cctools
sudo port install cctools

I followed the various remedies above but still no joy in Catalina.
