Cranelift Examples

 

Cranelift code generation comes to Rust

$ git clone https://github.com/rust-lang/rustc_codegen_cranelift
$ cd rustc_codegen_cranelift
$ ./y.sh build

 People can now try the Cranelift backend using rustup and cargo:

    $ rustup component add rustc-codegen-cranelift-preview --toolchain nightly
    $ export CARGO_PROFILE_DEV_CODEGEN_BACKEND=cranelift
    $ cargo +nightly build -Zcodegen-backend

Currently all my builds use Nix to automatically get dependencies, but it should work with manual dependency management using Homebrew/MacPorts/whatever as long as those dependencies are in your path when you run build-emacs-from-tar --no-deps (--no-deps should really be called --no-automatic-deps or something). Check the output of configure to see if it is detecting your dependencies.

Steps to resolve issue:

deleted previous build directory

git clone https://github.com/caldwell/build-emacs
./fetch-emacs-from-ftp -v ftp://ftp.gnu.org/pub/gnu/emacs 

./build-emacs-from-tar -v -j 8 --no-deps emacs-30.1.tar.bz2 release

cargo-generate bug iconv libiconv match libraries

linking error between macOS and macport provided libiconv library #1208

The problem is widespread and long lasting with many long discussions.

_libiconv or _iconv undefined symbol on Mac OSX

 

R-Problems with iconv on macOS

Longstanding GHC linking issues when multiple iconv libraries are installed on macOS (Haskell #18743)

 

long discussion:

MacOS iconv linkage misdetection (also deprecation warnings) #830

 

libiconv breaks compatibility with OS-provided #57821

 

rav1e @0.6.6: iconv linking fails, expecting symbols from MacOS's iconv lib #68026

rav1e: build fails due to git_allocator missing members #68178

 

Examples of possible fixes: 

ghc: Bugfixes for test and iconv linking #8523

Fix i/macOS libc++ initialization on early instrumentation #194

frida/frida-core

 

solution: libiconv on Mac OS X

FindIconv: Problem on macOS with mac ports

Ryan Carsten Schmidt @ryandesign · 1 year ago

I can't imagine how cmake could possibly help you with this problem. The only thing cmake does is tell you where libiconv is located. It should not matter at all to your application whether it tells you about a system copy of libiconv like the one in /usr on macOS or a third-party copy of libiconv like the one in /opt/local provided by MacPorts, so long as you use both the headers and the library from the same place. The only way the problem you're experiencing could occur is if you're using the headers from one place and the library from another, so Don't Do That.
