AOSP 构建错误 - 错误：在 PRODUCT_COPY_FILES 中发现 ELF 预构建，请改用 cc_prebuilt_binary / cc_prebuilt_library_shared

Question

我正在尝试将 Android Q 用户调试版本从我的 mac 电脑刷入我的 Pixel2 XL 设备，但它失败并显示以下错误消息。

以下是我的构建步骤：

mkdir ~/bin
export PATH=~/bin:$PATH
curl https://storage.googleapis.com/git-repo-downloads/repo > ~/bin/repo
chmod a+x ~/bin/repo
repo init -u https://android.googlesource.com/platform/manifest -b master
repo sync -c -j4
wget https://dl.google.com/dl/android/aosp/google_devices-taimen-qq1a.191205.008-f4537f93.tgz
tar xvf google_devices-taimen-qq1a.191205.008-f4537f93.tgz
./extract-google_devices-taimen.sh
wget https://dl.google.com/dl/android/aosp/qcom-taimen-qq1a.191205.008-760afa6e.tgz
tar xvf qcom-taimen-qq1a.191205.008-760afa6e.tgz
./extract-qcom-taimen.sh
. build/envsetup.sh
lunch aosp_taimen-userdebug
m

自从我第一次构建 AOSP 以来，我无法理解错误 found ELF prebuilt in PRODUCT_COPY_FILES, use cc_prebuilt_binary / cc_prebuilt_library_shared instead.

请告诉我该怎么做。谢谢。

此Issue Link 可能对您阅读有所帮助。

对于您的问题，我认为它与您下载的设备二进制文件有关。

尝试下载最新的，列在底部，为您像素 2 XL。

重做 extract*.sh 部分并重新制作！

我遇到了同样的错误。 是的，我们可以将此标志添加到 BoardConfig.mk，但这不是一个干净的解决方案，因为 Google 鼓励使用 Android.bp 文件而不是 Makefiles。这就是宋代建议使用这些模块的原因（cc_prebuilt_binary / cc_prebuilt_library_shared）。

在我的情况下，通过在我放置预建库的存储库中创建 Android.bp 文件解决了这个问题，然后我将它们作为产品包添加到产品 mk 文件中。这是一个例子：

Android.bp：

cc_prebuilt_library {
name: "product_package_name_in_MK_file",
relative_install_path: "sub_lib/sub_sub_lib",
stem: "output_file_name", // .so will be added automatically to out file name.
compile_multilib: "both",
multilib: {
lib32: {
srcs: ["path for src 32bit lib"],
},
lib64: {
srcs: ["path for src 64bit lib"],
},
},
strip: {
none:true,
},
allow_undefined_symbols: true,
check_elf_files: false,
vendor: true,
enabled: true,
}

product_mk 文件：

...
PRODUCT_PACKAGES += product_package_name_in_MK_file
...
