I SPENT THE LAST 10 HOURS TRYING TO BUILD RUSTC AND HOLY FUCK EVERYTHING IS SO OLD AND HACKY AND FUCKED UP THAT I DONT KNOW WHAT JUST HAPPENED BUT NOW YOURE GOING TO GO THROUGH IT WITH ME AGAIN
THATS RIGHT
IM GOING TO SUFFER THROUGH BUILDING RUSTC FROM SOURCE AGAIN, WITHOUT RUSTC ITSELF, WITHOUT THE ORIGINAL RUST COMPILER, ALL FOR THIS FUNNY INTERNET BLOG POST THAT FIVE PEOPLE WILL READ
UHUH
BUILDING RUSTC WITHOUT RUSTC AND LOSING MY SANITY AGAIN IN THE PROCESS
for the love of god and all that is holy please let this go well
GETTING STARTED
TO START US OFF lets make ourselves a container
THATS RIGHT A CONTAINER
WE GONNA GET GOOFY TODAY
1
distrobox create -n CrystalBoxFUCK -i registry.getcryst.al/crystal/misc/docker:latest --home $HOME/distroboxes/CrystalBoxFUCK
Why this niche distro in particular you might ask? No, because FUCK YOU
NOW LETS GET STARTED WITH MRUSTC and ENTER THE CONTAINER

distrobox enter CrystalBoxFUCK
git clone https://github.com/thepowersgang/mrustc.git
cd mrustc
git checkout b4503ee66847581e0483b6cff0ebc3a3d99fb4ff # because we don't want you cheating and taking advantage of any fixes until we fix them ourselves, now do we?
NOW lets BUILD IT. We’ll go with 1.39, because thats what I used first and I don’t want to spend ANOTHER TEN HOURS finding what needs to be included
1
./build-1.39.0.sh
wait fuck we need to download the base build dependencies or something and whatever the fuck else
1
ame ins cmake python --noconfirm
NOW if you wait a while for it all to build and fuck around youll see that mrustc likes to complain when it’s not on <= gcc12
lets tell it “fucking take it, I don’t want this include”
we’re gonna add #include <cstdint>:
src/mir/mir.hpp

now lets continue building again with ./build-1.39.0.sh
OH YOURE GETTING SMART WITH US
YOU WANT ANOTHER INCLUDE

would you believe me if I told you this is the last patch needed? no? well, I don’t blame you. but it is anyways, so we’re lucky. now we can actually build rustc.
building rustc
We’re building core, and the process only just begins.
We get through the first couple dozen steps, alright, alright, that’s good.
wait till we get to LLVM. Then the fun begins.
now wait for a long fucking time until it also complains about some compile errors about unused imports.
what will we do about this?
FUCK IT LETs PATch IT AGAIN

Now the final error is upon us. After this, it’s a clear road, all sunshine and rainbows.
openssl
nooOOOOOOOOOOOOOOOOOOOOOOOOOoooOOOOO
I;’m not even going to begin to start with openssl, so take this PKGBUILD and FUCK OFF

I literally just took the Arch openssl pkgbuild and hacked it together to make it work. and it works.
so run makepkg -sif and leave me alone.
Oh yeah and then run set -x OPENSSL_DIR /opt/openssl-1.1/ (or export OPENSSL_DIR=/opt/openssl-1.1)to make rustc see openssl, for some reason it refuses to see it otherwise. I’m too lazy to debug that.
The End.
You made it. Congratulations. Now you can work yourself up to the latest Rust compiler, cutting out a lot of the versions that came before, making it faster to get a fully working Rust env from scratch, no weird binaries needed.
This was so annoying to work with, and now I have to do it for even more Rust versions. Holy fuck. At least 10 hours wasted, easily. But it all looked so simple, right? Nope. I pulled an all-nighter trying to get this to work :P
Hopefully, in the future, mrustc can more easily go right to the newest/newer Rust versions so you don’t need to rebuild too much. In the meantime, have fun with this documentation regarding how I lost my mind and needed hours of sleep just to get rustc building.
Some things to keep in mind, from the mrustc developer:
If you’re building a rustc for use, then build 1.54 and step up from there I keep 1.19/1.29/1.39 as build targets because they’re good test coverage (and someday I’ll get time to add 1.69)
So progress :)
I’ll be submitting some patches upstream to help with mrustc, including this one, which involves the mrustc changes listed here: https://github.com/thepowersgang/mrustc/pull/305
