ld.exe: 找不到 -llog -lgcc -lc

Question

我正在尝试在 x86_64-pc-windows-msvc 主机上编译 x86_64-linux-android 目标。这是我的 .cargo/config:

[target.x86_64-linux-android]
ar = "C:/android-ndk-r10e/toolchains/x86_64-4.9/prebuilt/windows-x86_64/bin/x86_64-linux-android-ar"
linker = "C:/android-ndk-r10e/toolchains/x86_64-4.9/prebuilt/windows-x86_64/bin/x86_64-linux-android-ld"

当我使用 cargo build --target=x86_64-linux-android --target-dir=./out（cdylib 类型）编译我的项目时，出现此错误：

 note: C:/android-ndk-r10e/toolchains/x86_64-4.9/prebuilt/windows-x86_64/bin/x86_64-linux-android-ld.exe: error: cannot find -ldl

在一个类似的Whosebug post（参见：）中，使用的链接器是clang，但我好像找不到。我不确定在这种情况下我是否传递了“链接器”

Answer 1

我不得不更改 ndk 版本，并使用 llvm 工具链中的编译版本：

[target.x86_64-linux-android]
ar = "C:/android-ndk-r21d/toolchains/llvm/prebuilt/windows-x86_64/bin/x86_64-linux-android-ar"
linker = "C:/android-ndk-r21d/toolchains/llvm/prebuilt/windows-x86_64/bin/x86_64-linux-android29-clang.cmd"

特别注意，如上述线程中所见，要使用批处理文件。

ld.exe: 找不到 -llog -lgcc -lc

ld.exe: cannot find -llog -lgcc -lc
