 Posted: Sat May 09, 2020 11:03 pm Post subject: [SOLVED] GCC10 LTO breaks many compilations |
 |
|
EDIT: Best solution, provided by mike155 | Quote: | | Please try binutils-2.34-r1. |
You will have to accept the ** keyword on the 2.34-r1 binutils, I've tried and they work well.
Thank you!
Updating to GCC-10.1.0 and re-emerging @world led to many failed emerges.
(over 70 packages). The error is always the same, it starts with the same line during configure and breaks compilation on the same error.
| Code: | checking command to parse /usr/bin/x86_64-pc-linux-gnu-nm -B output from x86_64-pc-linux-gnu-gcc object... failed
...imagine a completed configure and a running compiler here...
../libtool: 1: eval: Syntax error: "|" unexpected |
Re-emerging libtool or binutils does not help.
The solution is to add the following to your CFLAGS: -ffat-lto-objects
and this to your make.conf: NM='gcc-nm --plugin ""'
Obviously, nm is broken with the lto plugin and needs proper symbol tables in object files

Will do, but currently I am on 2.34; so shouldn't the fix be there anyway?

| 2.34 is less than 2.34-r1, so assuming the title in the bug is accurate, then no, your version should not have the fix. |

aaand this is the definite proof that the biggest advantage is not being able to read, but actually reading.
I'll give the - r1 a shot, didn't have it in my portage tree yet.
Thanks for your patience

It is there, but it's masked. Add the line below to /etc/portage/package.accept_keywords:
| Code: | | =sys-devel/binutils-2.34-r1 ** |

Good morning,
after syncing my tree and unmasking binutils-2.34-r1, making sure they were selected I tried, and it works.
Thank you for your guidance, the community is definitely what makes gentoo a really great distribution!
