I have installed cargo and rustc through nix, and I have tried to check for the cc bin
❯ cc -v
clang version 7.1.0 (tags/RELEASE_710/final)
Target: x86_64-apple-darwin20.5.0
Thread model: posix
InstalledDir: /nix/store/rjy3p4j55ac4vyrmg18w2wrjgpfhsh4r-clang-7.1.0/bin
How can I fix this error?
This is still the first Google search result for "iconv cargo nix", so I'll post the solution I found here.
I am unsure whether or not this is intended or a bug in nixpkgs, but this error pops up because libiconv isn't included in the nix linker flags by default (you can check in $NIX_LDFLAGS). To include it, explicitly install it, e.g. via nix-shell:
# ↓↓↓↓↓↓↓↓
nix-shell -p libiconv -p cargo -p rustc -p rust-analyzer -p rustfmt -p clippy
I tried running ghc to compile a haskell program, and I get the following error:
$ ghc --make main

Here are some details about my machine:
macOS Catalina 10.15.7
Xcode 12.2
The Xcode developer tools were installed with xcode-select --install
I installed ghc with brew install ghc
Some other output that might be relevant:

Failed to build orjson
ERROR: Could not build wheels for orjson which use PEP 517 and cannot be installed directly
Please let me know what could I do? I have installed rustup and set it to nightly. Any help is greatly appreciated Thank you!
The problem is quite clear:
Your Rust target architecture (64-bit) does not match your python interpreter (32-bit)
Either upgrade your Python interpreter to 64 bit, or use rustup to install a 32 bit Rust target
Edit: Here is how you could manually target 32 bit on a x86_64 machine
I've constructed a simple Rust app as follows:
cargo new hello_world --bin
I can compile to WebAssembly using the Rust compiler as follows:
rustc +nightly --target wasm32-unknown-unknown -O src/main.rs
I'd like to use Cargo to manage external dependencies, but when I build for the same target using cargo:
cargo build --release --target wasm32-unknown-unknown
It fails as follows:
$ cargo build --release --target wasm32-unknown-unknown
error: failed to run `rustc` to learn about target-specific information
Caused by:
process didn't exit successfully: `rustc - --crate-name ___ --print=file-names --target wasm32-unknown-unknown --crate-type bin --crate-type rlib` (exit code: 101)
--- stderr
error: Error loading target specification: Could not find specification for target "wasm32-unknown-unknown"
|
= help: Use `--print target-list` for a list of built-in targets
As the wasm32-unknown-unknown target has only recently been added to Rust, it's only available in the nightly toolchain. You have to specify that you wish to use the nightly toolchain:
cargo +nightly build --release --target wasm32-unknown-unknown
# ^^^^^^^^
You were already doing this when calling rustc directly:
rustc +nightly --target wasm32-unknown-unknown -O src/main.rs
# ^^^^^^^^
It's probably easier if you:
Use a toolchain override in your project directory:
$ rustup override set nightly
Set a default target in your project's .cargo/config:
[build]
target = "wasm32-unknown-unknown"
Then you can just cargo build --release. (It's recommended to avoid debug mode for now).
