Hi,

I'm trying to compile the compiler. When running python3 x.py build, I run into an error when building stage 1 std artifacts:

error: internal compiler error: compiler/rustc_codegen_llvm/src/context.rs:176:13: data-layout for target `aarch64-unknown-freebsd-purecap`, `e-m:e-pf200:128:128:128:64-i8:8:32-i16:16:32-i64:64-i128:128-n32:64-S128-A200-P200-G200`, differs from LLVM target's `aarch64-unknown-freebsd` default layout, `e-m:e-i8:8:32-i16:16:32-i64:64-i128:128-n32:64-S128`

By any chance, did you already encountered this error?

(If need be, I can upload the full log and/or the config.toml)

(This error may also come from my (cheribuild built) LLVM, but since I encountered this error while trying to compile Rust, it could be useful to have a note about it here for future reference.)

Hi,

The Readme indicates to run ./cheribuild.py -d cheribsd-purecap-morello (https://github.com/kent-weak-memory/rust#build-cheri-bsd), but this returns an error:
Target cheribsd-purecap-morello does not exist. Did you mean cheribsd-release-morello-purecap or cheribsd-riscv64-purecap or cheribsd-morello-purecap?

I assume the Readme should be ./cheribuild.py -d cheribsd-morello-purecap ?

Best,
Martin

Hello,

I'm interested in studying the compilation process from Rust to CheriLLVM and I come across your compiler which I am trying to use and make it work. Following the setup instructions in the Readme file, I can successfully compile simple programs (without any dependencies) using both cargo and rustc. Also, I'm able to emit MIR and LLVM-IR files for both aarch64-unknown-freebsd-purecap and aarch64-unknown-freebsd targets.

However, when I attempt to compile programs with dependencies, I encounter the following error when compiling with cargo:

error: failed to download from `https://crates.io/api/v1/crates/addr2line/0.13.0/download`

Caused by:
  [60] SSL peer certificate or SSH remote key was not OK (SSL certificate problem: unable to get local issuer certificate)

I tried to fix this error by myself, trying several solutions, such as:

1. Putting http.check-revoke = false inside the .cargo/config.toml
2. Putting net.git-fetch-with-cli = true inside the .cargo/config.toml
3. Disabling firewalls
4. Not being behind a proxy
5. Updating certificates
6. Rebuilding the compiler from scratch

None of these solutions worked for me. Interestingly, I can access these dependencies with curl without any issues. Also, I tried using another cargo version (the one that is installable via rustup) to check if it can access any crate from crates.io (which it does successfully), so I'm suspecting that this might be actually an issue specific to this cargo version. Either it might be searching for certificates in the wrong directories or overlooking some directories when searching for the certificates.

While I am trying to find a solution (or a workaround) that can solve this problem, I want to ask you if you happened to encounter the same error (or a similar one) and how is it possible to solve it? I would greatly appreciate the assistance.

My environment details:

• WSL Environment: Ubuntu-22.04
• Rust version (the one of this repository):

rustc -vV

rustc 1.56.0-dev
binary: rustc
commit-hash: unknown
commit-date: unknown
host: x86_64-unknown-linux-gnu
release: 1.56.0-dev
LLVM version: 11.0.0

• Cargo version (the one of this repository):

cargo -vV

cargo 1.56.0-dev
release: 1.56.0

If any additional details are needed, I can gladly provide them.

Many thanks
