rust - ld.exe : cannot find -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"

当我用cargo build --target=x86_64-linux-android --target-dir=./out(cdylib类型)编译项目时，出现以下错误:

 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

在类似的StackOverflow帖子中(请参阅:Failed to cross-compile library from Windows to Android)，使用的链接器是clang，但我似乎找不到它。我不确定在这种情况下是否还要传递“链接器”

Answer 1

我必须更改ndk版本，并在llvm工具链中使用已编译的版本:

[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"

有一个特别的说明，如前面提到的线程所示，请使用批处理文件。
