How to compile armv7 arch in centos 7

[zenghp97]

I compiled the ARMV7 arch of libuv dynamic library in centos7 with android-ndk-r21b. as follow command:
cmake ../ -DCMAKE_SYSTEM_NAME=Android -DCMAKE_ANDROID_NDK=/data/src/utopalive/network/20200409/tool/android/android-ndk-r21b -DCMAKE_SYSTEM_VERSION=24 -DCMAKE_C_COMPILER=aarch64-linux-android-gcc

Compile failed with the following information:

-- The C compiler identification is unknown
CMake Error at CMakeLists.txt:2 (project):
The CMAKE_C_COMPILER:

aarch64-linux-android-gcc

is not a full path and was not found in the PATH.

Tell CMake where to find the compiler by setting either the environment
variable "CC" or the CMake cache entry CMAKE_C_COMPILER to the full path to
the compiler, or to the compiler name if it is in the PATH.

thus, how to compile armv7 ach in centos 7? thanks!

I'm moving this to libuv/help because that looks like a system-local issue, not libuv.

You probably need to either pass the full path in -DCMAKE_C_COMPILER=aarch64-linux-android-gcc or make sure it's on your PATH.

It feels unfriendly to remove the Android Help for compile cross platform. At a minimum, you need to give a description of the variables or macros required. Otherwise, how would anyone know?

To set expectations straight: Android is not a supported platform. We accept pull requests but other than that you're on your own.
