 |
|
There are several months since I've been trying to update www-client/qutebrowser, but the ebuild just drops off due to dev-util/maturin, wihch always fails to build due to undefined references. It's important to say that use a lot of optimization flags from GentooLTO.
The output of `emerge --info '=dev-util/maturin-0.11.5::gentoo'` can be found here.
The output of `emerge -pqv '=dev-util/maturin-0.11.5::gentoo'` can be found here.
The content of `/var/tmp/portage/dev-util/maturin-0.11.5/temp/build.log` can be found here.
There are other packages that is failing to build. I'll post new topics for them soon.

Hi atchim,
welcome to the Gentoo forums!

Wait... Your configuration deviates from the recommended settings. It's no surprise that you run into problems...
| Code: | | ACCEPT_KEYWORDS="amd64 ~amd64" |
| Code: | | CFLAGS="-O3 -fgraphite-identity -floop-nest-optimize -fdevirtualize-at-ltrans -fipa-pta -fno-semantic-interposition -flto=auto -fuse-linker-plugin -falign-functions=32 -march=native -pipe" |
The Gentoo handbook recommends to stay on stable (link) and to use "CFLAGS="-O2 -march=native -pipe". -O3 is known to break several packages and may make your system slower (link, link).
Why don't you go back to the default settings? You could pick a few packages you really care about - and compile those with -O3, LTO or use the unstable/testing versions. In order to do that, we have /etc/portage/package.accept_keywords and /etc/portage/package.env. But most tools like bash, grep, sed surely won't get any better if you compile them with -O3 and without extensive testing and source code optimization. It just doesn't make sense to compile source code you haven't written and tested yourself with the CFLAGS you use. It's like driving a car with blindfolded eyes.

I can reproduce if I use -flto, so yeah, your CFLAGS are causing the issue.
Guess I could have the ebuild force disable lto for what it's worth, but if you're going to use these flags I'd suggest that turning these off is the first thing you try when running into problems.
Edit: done in this commit, if emerge --sync it should work now. Hoped for fix rather than a workaround (e.g. have -sys crates use system libs) but can't for ring crate. |

| Hi Mike! My system has almost 1000 packages, but just about 5 packages are breaking currently. I think it worths to "live in the bleeding edge" since I've learnt a lot about Gentoo, ebuild, C, Rust, etc. However, thanks for the advice! I really appreciate that! |

Successfully emerged dev-util/maturin and so www-client/qutebrowser! Really thanks, Ionen! |
