最近的 API 级别（例如 22）也会出现同样的问题。

我正在使用 https://github.com/golang/go/wiki/Ubuntu

中提到的 golang-1.8-go 包

编译命令不完整。您可以使用 gomobile build -x 查看如何正确调用编译器，请记住您可能需要在 shell.

中正确引用参数

正确命令示例：

GOMOBILE=/home/janus/go/pkg/gomobile GOPATH=$HOME/go ANDROID_HOME=/home/janus/Desktop/android-sdk-linux GOOS=android GOARCH=arm CC=$ANDROID_HOME/ndk-bundle/toolchains/llvm/prebuilt/linux-x86_64/bin/clang CXX=$ANDROID_HOME/ndk-bundle/toolchains/llvm/prebuilt/linux-x86_64/bin/clang++ CGO_CFLAGS="-target armv7a-none-linux-androideabi --sysroot $ANDROID_HOME/ndk-bundle/platforms/android-15/arch-arm -gcc-toolchain $ANDROID_HOME/ndk-bundle/toolchains/arm-linux-androideabi-4.9/prebuilt/linux-x86_64 -I$GOMOBILE/include" CGO_CPPFLAGS="-target armv7a-none-linux-androideabi --sysroot $ANDROID_HOME/ndk-bundle/platforms/android-15/arch-arm -gcc-toolchain $ANDROID_HOME/ndk-bundle/toolchains/arm-linux-androideabi-4.9/prebuilt/linux-x86_64 -I$GOMOBILE/include" CGO_LDFLAGS="-target armv7a-none-linux-androideabi --sysroot $ANDROID_HOME/ndk-bundle/platforms/android-15/arch-arm -gcc-toolchain $ANDROID_HOME/ndk-bundle/toolchains/arm-linux-androideabi-4.9/prebuilt/linux-x86_64 -L$ANDROID_HOME/ndk-bundle/platforms/android-15/arch-arm/usr/lib -L$GOMOBILE/lib/arm" CGO_ENABLED=1 GOARM=7 go build -pkgdir=$GOMOBILE/pkg_android_arm -buildmode=c-shared
