Error Encountered with x86_64-unknown-linux-gnu Cross Compile Tool: Cannot Find -lc++

[0xtyls]

Hello,

I am utilizing your x86_64-unknown-linux-gnu cross-compile tool for Rust projects, and I've encountered an error during the process. Here's the error message I received:

note: /opt/homebrew/Cellar/x86_64-unknown-linux-gnu/0.1.0/bin/../lib/gcc/x86_64-unknown-linux-gnu/11.2.0/../../../../x86_64-unknown-linux-gnu/bin/ld.bfd: cannot find -lc++
          collect2: error: ld returned 1 exit status

Upon further investigation, I searched the directory /opt/homebrew/Cellar/x86_64-unknown-linux-gnu, but could not find any files matching libc++*.

I am interested in understanding the creation process of these cross-compile tools, which might provide insight into solving the issue. Would you be able to share some details on how these tools are created? Additionally, any advice on resolving the aforementioned error would be highly appreciated.

Thank you for your time and assistance.

Would you be able to share some details on how these tools are created?

The script used to build them is public in this repository! https://github.com/MaterializeInc/homebrew-crosstools/blob/main/lib/toolchain.rb

Additionally, any advice on resolving the aforementioned error would be highly appreciated.

I'm not sure anyone's ever tried to use these binutils to build C++. There may be an additional crosstool flag we need to enable to build libc++.
