#59351 closed defect (fixed)

Cannot compile gfortran (or even libgcc7) under Catalina

Reported by: thepeteriley (Pete Riley) Owned by: Chris Jones <jonesc@…>
Priority: Normal Milestone:
Component: ports Version:
Keywords: catalina Cc: LeoFCardoso (Leonardo)
Port: gcc7

Description (last modified by kencu (Ken))

Following the instructions, including a clean install of Catalina and a clean install of Macports, after getting a first round of errors, then forcibly deactivating libunwind-headers, the installation of gfortran continued until:

--->  Building libgcc7
Error: Failed to build libgcc7: command execution failed
Error: See /opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports.org_macports_release_tarballs_ports_lang_gcc7/libgcc7/main.log for details.
Error: Follow to report a bug.
Error: Processing of port gcc6 failed

I'm happy to send a full log if needed, but I don't want to bog this message down with it unless it's necessary.

This is my first ticket to macports (I've never encountered an issue that I couldn't resolve in the past :)), please let me know if the information is useful and/or whether it should have been posted somewhere else?

Thank you for the report!

Unfortunately, gcc has so far only made gcc9 compatible with Catalina. Perhaps you might be able to use gcc9 in your project.

gcc9 should be the current default, but if you're upgrading from older installations, you might still be calling in gcc7, which does not work on Catalina at present.

We don't yet have a timeline on when or if gcc7 will work with Catalina.

Ryan, Chris, Josh -- should we just put a Catalina blocker in all gcc versions < gcc9, to head off these tickets? We can update that if/when the fixes are ported to older versions.

The only loss here is pdftk, for which I think there is another alternative now that doesn't need gcc5.

I update Xcode and command line tools to Xcode 11.3 (11C29) on my Mac. And I commented out the pre-fetch check code, of my local Portfiles for libgcc7, libgcc6 and gcc5 and succeed to install them without any problems. Please update this issue again!

thanks for the pointer. I've committed an update allowing these builds for Xcode 11.3+ on Darwin19 and newer.
