With help of vadorovsky, I've learned that I need to pass --no-default-features, and then it uses system LLVM which resolves problems 2. and 4. 2. <a href="https://social.treehouse.systems/tags/LLVM" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#LLVM</a> 20 still fails on that assertion, but Tuesday's LLVM 21 snapshot works fine. 3. I also needed to package btfdump for bpf-linker's tests but I was finally able to get them to pass. 4. After spending hours trying to figure out mitmproxy-linux build failures, I've finally found a way to build it: I need to remove upstream's logic for building bpf binaries, build them manually with correct RUSTFLAGS, and then build the whole thing. <a href="https://github.com/mitmproxy/mitmproxy/issues/7663" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://github.com/mitmproxy/mitmproxy/issues/7663</a> 5. rustc-build-sysroot crate problem is even worse in mitmproxy-linux. 6. mitmproxy-linux's tests segfault (yeah, <a href="https://social.treehouse.systems/tags/RustLang" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#RustLang</a>). 7. But still, with the packages built, I can get tests to pass on mitmproxy itself.So yeah, if I can only figure out what to do about these segfaulting tests, I think we can get new mitmproxy version into <a href="https://social.treehouse.systems/tags/Gentoo" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Gentoo</a>. Pinned to one Rust version, but that's better than nothing, I guess.

No, not at the conference.Because if you ever were wondering what LLVM project's attitude towards its volunteer contributors is, just look at the ticket prices. I mean, which volunteer would spend $750 on a conference ticket?!But yeah, we know our place. It's to spend weekends fixing what corporate contributors broke through the week, then beg them to actually review our fixes before they break more.

Giacomo Tesio<a href="https://mastodon.social/users/ekaitz_zarraga" class="u-url mention" rel="nofollow noopener noreferrer" target="_blank">@ekaitz_zarraga@mastodon.social</a> That's not the most absurd dependency I've seen so far. For example, to bootstrap <a href="https://snac.tesio.it?t=llvm" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#LLVM</a> you used to need <a href="https://snac.tesio.it?t=gcc" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#GCC</a>. 🤣 (not sure it's still the case).

David Chisnall (*Now with 50% more sarcasm!*)One of the reasons I'm still using GitHub for a lot of stuff is the free CI, but I hadn't really realised how little that actually costs. For <a href="https://infosec.exchange/tags/CHERIoT" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#CHERIoT</a> <a href="https://infosec.exchange/tags/LLVM" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#LLVM</a>, we're using Cirrus-CI with a 'bring your own cloud subscription' thing. We set up ccache backed by a cloud storage thing, so incremental builds are fast. The bill for last month? £0.31.We'll probably pay more as we hire more developers, but I doubt it will cost more than £10/month even with an active team and external contributors. Each CI run costs almost a rounding-error amount, and that's doing a clean (+ ccache) build of LLVM and running the test suite. We're using Google's Arm instances, which have amazingly good price:performance (much better than the x86 ones) for all CI, and just building the x86-64 releases on x86-64 hardware (we do x86-64 and AArch64 builds to pull into our dev container). For personal stuff, I doubt the CI that I use costs more than £0.10/month at this kind of price. There's a real market for a cloud provider that focuses on scaling down more than on scaling up and made it easy to deploy this kind of thing (we spent far more money on the developer time to figure out the nightmare GCE web interface than we've spent on the compute. It's almost as bad as Azure and seems to be designed by the same set of creatures who have never actually met a human).
