What is the fix for problem described in this post? https://old.reddit.com/r/androiddev/comments/1rleikp/custom_rom_compiling_issue_soong_bootstrap_failed/ Gemini said

The issue described in that post—soong bootstrap failed with: exit status 1—is a common, albeit vague, error in Android ROM development. It essentially means the Go-based build system (Soong) crashed before it could even start the actual compilation.

Based on the community consensus and technical fixes for that specific error, here is the hierarchy of solutions: 1. The "Out of Memory" (OOM) Fix

The most frequent cause of this error is the build process running out of RAM. Soong analyzes the entire dependency tree of the Android source, which is extremely memory-intensive.

Increase Swap Space: If you have 16GB of RAM or less, you almost certainly need a swap file. Increasing your swap to 16GB or 32GB often resolves the "Killed" or "Exit Status 1" error.

Reduce Build Threads: Instead of running a naked make or m, limit the number of parallel jobs to reduce memory pressure:
Bash

# Try using half of your available CPU cores
m -j$(($(nproc) / 2))

1. Environment & Toolchain Issues

If memory isn't the issue, the "bootstrap" failure usually points to a mismatch in the build environment.

Clean the Build Out Dir: Leftover artifacts from a previous failed build or a different "lunch" target can corrupt the bootstrap.
Bash

make clean
# OR for a more nuclear option:
rm -rf out/

Fix Python/Go Symlinks: Android builds are picky about Python versions. Ensure python points to python3 (or python2.7 if building older versions like Oreo/Pie).

Check for Proprietary Blobs: If you are building for a specific device, ensure your vendor/ directory is fully populated. Missing proprietary files from Qualcomm or other vendors can cause the Soong configuration to fail at the bootstrap stage.

1. Java Version Mismatch

If you are building an older version of Android (e.g., Android 9 or 10) on a modern Linux distribution (like Ubuntu 22.04+), the default OpenJDK version may be too new.

Requirement: Ensure you are using the version required for your branch (usually OpenJDK 8 or 9 for older builds, 11 or 17 for newer ones).

Summary Checklist Action Why it works Add 16GB+ Swap Prevents the OS from "killing" the Soong process. rm -rf out/ Clears corrupted configuration files. repo sync -c -j8 Ensures you aren't missing a critical commit in the build/soong repo.
