在setSdclangVars（）上的soong-cc-config測試中，構建Android msm-3.18內核失敗

Question

我正在嘗試為msm8996（Android 8.0.0）構建msm-3.18內核。 嘗試從Android源頂層目錄進行構建時，運行測試失敗。

以下是痕跡

FAILED: out/soong/.bootstrap/soong-cc-config/test/test.passed

我想這與$ SDCLANG_PATH有關，但我需要幫助

您需要在Qualcomm開發人員網絡上注冊並下載其專有編譯器。

根據他們論壇上的指示：

1. 在此處下載Qualcomm LLVM編譯器： https : //developer.qualcomm.com/download/sdllvm/snapdragon-llvm-compiler-android-linux64.tar.gz

2. 解壓縮Snapdragon-llvm-3.8.4-toolchain.tar.gz

3. 將工具鏈\\ llvm-Snapdragon_LLVM_for_Android_3.8 \\ prebuilt \\ linux-x86_64移至Android構建環境中的prebuilts / clang / host / linux-x86 / sdclang-3.8。

4. 將以下行添加到設備的BoardConfig中：

    ifneq ($(HOST_OS),darwin) SDCLANG := true SDCLANG_PATH := prebuilts/clang/host/linux-x86/sdclang-3.8/bin SDCLANG_LTO_DEFS := device/qcom/common/sdllvm-lto-defs.mk endif 

5. 編譯Android。
