How to Fix: Linking error when building LLVM with Debug symbols

LLVM build error with Debug symbols

Quick Answer: The issue is likely due to the missing `--target` option in the `cmake` command. Add `--target x86_64-unknown-linux-gnu` to specify the target architecture for building LLVM.

Linking error when building LLVM with Debug symbols can be frustrating, especially when working inside a container. This issue arises due to the way the linker is configured.

🔍 Why This Happens

  • When building with Debug symbols, the linker requires additional libraries to resolve symbol references. However, in a containerized environment, these libraries might not be available or correctly configured.

🚀 How to Resolve This Issue

Method 1: Install Required Libraries

  1. Step 1: Update the Dockerfile to include the necessary libraries:

Install Required Libraries

RUN apt-get install -y --no-install-recommends \ libasan-dev \ libclangdev-dev \ liblldb-dev \ librtdev \ libsanitizer-dev \ libstdc++-dev

Method 2: Configure Linker Flags

  1. Step 1: Modify the CMake configuration to include linker flags that link against required libraries:

Configure Linker Flags

RUN cmake -S llvm -B build \ -G Ninja \ -DCMAKE_BUILD_TYPE=Debug \ -DCMAKE_INSTALL_PREFIX=/usr/local \ -DLLVM \ -DLIBRARY_PATH=/usr/lib \ -L/usr/lib/llvm

🎯 Final Words

By following these steps, you should be able to resolve the linking error when building LLVM with Debug symbols inside your container.
