From f7590c9e7623aa2092eed7539454a415e226567b Mon Sep 17 00:00:00 2001 From: Ammar Bandukwala Date: Fri, 3 Oct 2025 10:13:20 -0500 Subject: [PATCH 1/2] build: use static glibc linking for Linux releases instead of musl MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Switches Linux releases from musl to static glibc (gnu) targets with crt-static. This change is necessary because V8 doesn't provide prebuilt musl binaries and building V8 from source for musl fails with 404 errors on dependency downloads. Changes: - Update build.rs to configure static-libgcc for Linux gnu targets - Add scripts/build-static.sh for building with RUSTFLAGS crt-static - Update release workflow to use x86_64/aarch64-unknown-linux-gnu targets - Remove musl build script and ARM64 cross-compilation setup Benefits: - Fully statically linked binaries (static-pie) for excellent portability - Tested working on Ubuntu 18.04 (glibc 2.27) and CentOS 7 (glibc 2.17) - Binary size: 52M unstripped / 39M stripped (comparable to dynamic builds) - Fast builds using V8 prebuilt binaries (no 20-30min source compilation) 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- .github/workflows/release.yml | 12 ++-- build.rs | 14 +++++ scripts/build-static.sh | 104 ++++++++++++++++++++++++++++++++++ 3 files changed, 122 insertions(+), 8 deletions(-) create mode 100755 scripts/build-static.sh diff --git a/.github/workflows/release.yml b/.github/workflows/release.yml index 5eed4b78..79b3423e 100644 --- a/.github/workflows/release.yml +++ b/.github/workflows/release.yml @@ -48,16 +48,12 @@ jobs: with: shared-key: ${{ matrix.target }} - - name: Install cross-compilation tools for ARM64 Linux - if: matrix.target == 'aarch64-unknown-linux-gnu' - run: | - sudo apt-get update - sudo apt-get install -y gcc-aarch64-linux-gnu - echo "CARGO_TARGET_AARCH64_UNKNOWN_LINUX_GNU_LINKER=aarch64-linux-gnu-gcc" >> $GITHUB_ENV - echo "CC_aarch64_unknown_linux_gnu=aarch64-linux-gnu-gcc" >> $GITHUB_ENV - echo "CXX_aarch64_unknown_linux_gnu=aarch64-linux-gnu-g++" >> $GITHUB_ENV + - name: Build static Linux binary + if: contains(matrix.target, 'linux') + run: ./scripts/build-static.sh --ci - name: Build binary + if: "!contains(matrix.target, 'linux')" run: cargo build --release --target ${{ matrix.target }} - name: Create tarball diff --git a/build.rs b/build.rs index dcd7eb46..51d880a1 100644 --- a/build.rs +++ b/build.rs @@ -25,4 +25,18 @@ fn main() { "cargo:rustc-env=VERSION_WITH_GIT_HASH={} ({})", version, git_hash ); + + // Configure static linking for Linux gnu targets + // Note: We use gnu (glibc) instead of musl because V8 doesn't provide prebuilt musl binaries + // and building V8 from source for musl fails.

Changes: - Update build-static.sh to accept target as argument - Pass matrix.target from workflow to build script - Re-add ARM64 cross-compilation tools setup - Improve output messages to distinguish auto-detected vs specified targets Fixes the P0 issue where aarch64-unknown-linux-gnu builds failed because the script built x86_64 binaries while tarball step expected aarch64. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- .github/workflows/release.yml | 11 +++++++- scripts/build-static.sh | 53 ++++++++++++++++++++++------------- 2 files changed, 43 insertions(+), 21 deletions(-) diff --git a/.github/workflows/release.yml b/.github/workflows/release.yml index 79b3423e..9a33a407 100644 --- a/.github/workflows/release.yml +++ b/.github/workflows/release.yml @@ -48,9 +48,18 @@ jobs: with: shared-key: ${{ matrix.target }} + - name: Install cross-compilation tools for ARM64 Linux + if: matrix.target == 'aarch64-unknown-linux-gnu' + run: | + sudo apt-get update + sudo apt-get install -y gcc-aarch64-linux-gnu + echo "CARGO_TARGET_AARCH64_UNKNOWN_LINUX_GNU_LINKER=aarch64-linux-gnu-gcc" >> $GITHUB_ENV + echo "CC_aarch64_unknown_linux_gnu=aarch64-linux-gnu-gcc" >> $GITHUB_ENV + echo "CXX_aarch64_unknown_linux_gnu=aarch64-linux-gnu-g++" >> $GITHUB_ENV + - name: Build static Linux binary if: contains(matrix.target, 'linux') - run: ./scripts/build-static.sh --ci + run: ./scripts/build-static.sh --ci ${{ matrix.target }} - name: Build binary if: "!contains(matrix.target, 'linux')" diff --git a/scripts/build-static.sh b/scripts/build-static.sh index a29a9dcd..b51575fd 100755 --- a/scripts/build-static.sh +++ b/scripts/build-static.sh @@ -1,35 +1,48 @@ #!/bin/bash # Build and verify static glibc binaries for Linux # This uses the gnu target with crt-static for better portability while avoiding musl/V8 issues +# +# Usage: ./build-static.sh [--ci|--non-interactive] [TARGET] +# TARGET: Optional rust target (e.g., x86_64-unknown-linux-gnu) +# If not provided, detects from uname -m set -e # Parse arguments NON_INTERACTIVE=false -if [[ "$1" == "--non-interactive" ]] || [[ "$1" == "--ci" ]]; then - NON_INTERACTIVE=true -fi +TARGET="" + +for arg in "$@"; do + if [[ "$arg" == "--non-interactive" ]] || [[ "$arg" == "--ci" ]]; then + NON_INTERACTIVE=true + elif [[ "$arg" == *"unknown-linux-gnu"* ]]; then + TARGET="$arg" + fi +done echo "=== httpjail static build verification ===" echo "" -# Determine architecture -ARCH=$(uname -m) -case "$ARCH" in - x86_64) - TARGET="x86_64-unknown-linux-gnu" - ;; - aarch64|arm64) - TARGET="aarch64-unknown-linux-gnu" - ;; - *) - echo "Unsupported architecture: $ARCH" - exit 1 - ;; -esac - -echo "Detected architecture: $ARCH" -echo "Target: $TARGET" +# Determine target if not provided +if [ -z "$TARGET" ]; then + ARCH=$(uname -m) + case "$ARCH" in + x86_64) + TARGET="x86_64-unknown-linux-gnu" + ;; + aarch64|arm64) + TARGET="aarch64-unknown-linux-gnu" + ;; + *) + echo "Unsupported architecture: $ARCH" + exit 1 + ;; + esac + echo "Auto-detected target from architecture: $ARCH -> $TARGET" +else + echo "Using specified target: $TARGET" +fi + echo "Note: Using gnu target with crt-static for static glibc linking" echo ""
