This repository contains impostor binaries for GCC and Clang that redirect compilation and linking tasks to the Wild linker. This allows you to use Wild as your default linker without modifying your existing build processes.
Note: -fuse-ld and --ld-path will be ignored when using these impostor binaries, at least for now.
There are a couple of ways to use these impostor binaries:
- prepend
fakes/(symlinks to target/release) orfakes-debug/(symlinks to target/debug) to yourPATH:PATH=~/Projects/wild-proxy/fakes:$PATH cmake -B build/ -DCMAKE_BUILD_TYPE=Release -GNinja - use either one of the impostor symlinks or
wild-proxydirectly:~/Projects/wild-proxy/target/debug/wild-proxy hello.c - use the original compiler to build and wild-proxy to link:
g++ hello.cc -c; ~/Projects/wild-proxy/target/debug/wild-proxy hello.o -lstdc++
For Rust, you can set the linker in .cargo/config.toml:
[target.x86_64-unknown-linux-gnu]
linker = "wild-proxy"or use RUSTFLAGS=-Clinker=wild-proxy.
Not yet implemented.
Even though wild-proxy has to call the compiler additional time in this mode with -### argument, the performance is
roughly on par to using -B<path to wild> with GCC/Clang directly, presumably because of the linker being integrated
into this binary.
For reference, with hello.c -### -o /tmp/bin the tested GCC 15.2.1 takes just 381.5 µs and Clang takes an order
of
magnitude
more at
3.9 ms. But for various reasons like more parsing and calling two additional processes when using GCC (one to create
assembly and another one to assemble an object) the differences almost cancel out.

Even when only compiling the unrealistically small source files (hello world), the impostor binaries have minimal overhead. Which is negligible for real-world projects.

There are no proper tests yet, I've only tested this manually on Arch Linux.
