…1626) The Linux build instructions referenced a "Clang-9 toolchain" for a package install command that actually installs `g++` (GCC), not Clang. ## Change - Updated the description label from "Clang-9 toolchain" → "GCC toolchain" to accurately reflect the `apt install` command that follows it. <!-- START COPILOT CODING AGENT TIPS --> --- 💡 You can make Copilot smarter by setting up custom instructions, customizing its development environment and configuring Model Context Protocol (MCP) servers.

…nstructions (#1627) The Linux build instructions listed `libjavascriptcoregtk-4.1-dev` in the base mandatory packages, causing it to be installed for all engine targets (including V8) and duplicating the engine-specific install step. The base command also used `apt` while engine-specific steps used `apt-get`. ## Changes - **Remove `libjavascriptcoregtk-4.1-dev` from base install** — engine-specific packages now live only in their respective engine sections - **Standardize on `apt-get`** throughout the Linux section for consistency Before: ``` sudo apt install libgl1-mesa-dev x11proto-core-dev libx11-dev libcurl4-openssl-dev libjavascriptcoregtk-4.1-dev g++ cmake ninja-build npm ``` After: ``` sudo apt-get install libgl1-mesa-dev x11proto-core-dev libx11-dev libcurl4-openssl-dev g++ cmake ninja-build npm ``` <!-- START COPILOT CODING AGENT TIPS --> --- 🔒 GitHub Advanced Security automatically protects Copilot coding agent pull requests.

The JavaScriptCore cmake invocation in `BUILDING.md` contained a stray `-D` flag (`-D -D NAPI_JAVASCRIPT_ENGINE=...`), making it an invalid command that would fail immediately. ## Changes - **Remove stray `-D`** from the JavaScriptCore cmake command - **Add `-B build/linux`** to both JavaScriptCore and V8 cmake commands — consistent with every other platform section in the docs - **Replace bare `ninja`** with `cmake --build build/linux` to match the out-of-source build pattern used elsewhere Before/after for the broken command: ```sh # Before (invalid) cmake -G Ninja -D -D NAPI_JAVASCRIPT_ENGINE=JavaScriptCore # After cmake -B build/linux -G Ninja -D NAPI_JAVASCRIPT_ENGINE=JavaScriptCore ``` <!-- START COPILOT CODING AGENT TIPS --> --- 💡 You can make Copilot smarter by setting up custom instructions, customizing its development environment and configuring Model Context Protocol (MCP) servers.
