Folks, I'm nearly through the profile migration, but I'm stuck on the final step of emerge --emptytree. For some reason, sys-devel/gcc-14.2.1_p20241221 is failing to compile. I'm copying the error below. This bug is different enough from the original topic of this thread that it might warrant forking off into a new thread, but perhaps someone can spot an obvious issue? I've previously migrated two other machines without issue, and it's weird that gcc of all things would fail to compile.

First, I guess you didn't read the news item carefully. I'm guilty of that too.
Second, use the binhost. All that compilation and fixing the breakages is unnecessary. It also takes a lot of time. It took me nearly 6 hours and a half for ~1500 packages when more than 2/3 of them were binary. And I have decent hardware with enough RAM, good CPU and an SSD disk.
Best Regards,
Georgi

jyoung,
When you build gcc it bootstraps itself. That means it builds three times.
1. gcc is built with any random C/C++ on the system. It need not be gcc
2. The gcc C/C++ compiler from 1. is used to build gcc C/++, so its now built with itself.
3. The gcc C/C++ from stage 2 builds gcc C/C++ again. This gcc C/C++ should be identical to the output from stage 2. If not the build fails.
Stage 3 continues by building all the languages you have asked for. This then gets installed.
When can see you have a linker error but not at which stage the build failed. For that we need the command that invoked the fail.
I'll infer its well into stage 3 from | Code: | | rm gfdl.pod gcc.pod gfortran.pod gcov-dump.pod gcov-tool.pod fsf-funding.pod gpl.pod cpp.pod gcov.pod lto-dump.pod |
which mentions fortran.
Fortran is not built in the first two stages. Only C and C++, which is all that's needed to build gcc.
The entire build log would be good.
Hmm ...
| Code: | make[2]: *** [Makefile:4876: all-stageprofile-gcc] Error 2
make[1]: *** [Makefile:24632: stageprofile-bubble] Error 2
make: *** [Makefile:24870: profiledbootstrap] Error 2 |
Profile Guided Optiminisation?
Don't do that to gcc.

Okay, it's likely passing through the first two stages okay, but getting stuck on the third. That make sense, since Fortran is just something that I need for work. I've copied below the output of emerge --info '=sys-devel/gcc-14.2.1_p20241221::gentoo'. I could also include /var/tmp/portage/sys-devel/gcc-14.2.1_p20241221/temp/build.log, although it is quite long. NeddySeagoon, I'm not sure what could have triggered profile guided optimization for gcc. I have tweaked the use flags, but just for items like enabling fortran. logrusx, by using the binhost do you mean in step 8? On my system the file /etc/portage/binrepos.conf doesn't exist. To clarify, this bug is showing up on step 16.

I don't remember the news item by heart, but I'm pretty certain you made a mistake somewhere in the first steps. Go back and read it very carefully and try to remember exactly what you did. Also there were threads at the time of transitioning to 23.0 for gcc breakages.
Yes, I mean setting up the binrepos.conf and this way using the binhost so you don't need to build all that stuff. And step 16 is pretty fat ahead, if not the last one. If you had problems with gcc you should have already hit them. Once again, did you read the news item carefully and did you follow it exactly?
EDIT:
I mean this particular step:
| Code: | 9. Rebuild or reinstall from binary (if available) the following packages in
this order, with the same version as already active:
emerge --ask --oneshot sys-devel/binutils
(you may have to run binutils-config and re-select your binutils now)
emerge --ask --oneshot sys-devel/gcc |
| Quote: | (IMPORTANT: If this command wants to rebuild glibc first, do *not* let it do
that; instead, abort and try again with --nodeps added to the command line.) |
| Code: | (you may have to run gcc-config and re-select your gcc now)
and the C library, i.e. for glibc-based systems
emerge --ask --oneshot sys-libs/glibc
or for musl-based systems
emerge --ask --oneshot sys-libs/musl |
Did you follow the order exactly?
Best Regards,
Georgi |

logrusx, I'm happy to to go back if need be. I was pretty diligent the first time through, but, agreed, clearly there was some mistake. On step 9, I did catch that note about rebuilding gcc but not glibc, and I did have to use the --nodeps option. Concerning the two notes:
| Code: |
(you may have to run binutils-config)
|
| Code: | | (you may have to run binutils-config) |
I didn't do either of these items, since there was no sign that I had to. Perhaps I should have? |

I can't tell. Why don't you setup the binhost already? It's THE ABSOLUTE EASIEST SOLUTION. At least for gcc/glibc/binutils. Then you can rebuild them if you want. But once --emptytree breaks, you start from the beginning, do you realize that?
At least start a new thread, I can assure you this is not attracting the attention of the right people.
p.s. or ask the moderators to split it.

Sorry it's been a while since I posted. As you suggested, I was about to start a new thread on the migration topic, but I thought to first isolate the error with
| Code: | | emerge gcc --oneshot |
That way, as folks chimed in to help, I wouldn't have to emerge world with --emptytree every time. But, that oneshot command succeeded, which seemed weird. So, I returned to the final step of the profile migration instructions
| Code: | | emerge --ask --emptytree @world |
And that worked this time. Any ideas why?
Since it would seem that the profile is now updated, I checked the status of libreoffice:
Copy/paste work, but operations need to be done twice. The first time, the item is copied as an image, even if it's a textbook or the like. |
