gcc9 build log

You got this again, eh?

I don't see this, nor do the buildbots.

Can you please show me the output of this command?

$ port select --summary

thanks! (BTW, the buildbot has served this up now, so you should soon be able to just download the prebuilt version from MacPorts' servers and then you won't have to worry about building it.

Don't be too frustrated. Building compilers like gcc or clang is about the most difficult thing you could ever ask of your system. It has to be perfect, pretty much -- all tools at the correct right versions, the right Xcode, the matching command line tools, the current correct versions of cctools and ld64, and nothing sudo port select'ed to screw up the right helper programs being found at the right time during the build.

If even one little thing is out of proper order or position -- BOOM. No gcc build.

well, it's none of those....

Let's leave it for now...gcc9 is just too hard to use to debug your system.

If you notice other build failures we can work on those instead I think.

Hi, When the precompiled package for 10.7.5 was not found in the repositories, the compilation from sources was automatically launched and this operation was successful even if it took many hours to complete. Next time if necessary. Thank you!

[kencu (Ken)]

oh, so it did work in the end. very good!
