Unable to Cross Compile gRPC

[antne...@gmail.com]

I am trying to cross compile the gRPC code on my Ubuntu 14-04 Linux system and I am getting the following error:

The target OS is an embedded system using an ARM Cortex A8 processor.

Any help would be appreciated.

oh,I have the same error,and I vim  it's CmakeLists,but it alaways has other error,

arm-linux-gnueabihf-g++: error: unrecognized command line option ‘-maes’; did you mean ‘-mapcs’?

arm-linux-gnueabihf-g++: error: unrecognized command line option ‘-msse4’

 vim ../third_party/boringssl-with-bazel/CMakeLists.txt +99

 set(ARCH "arm")

I'm using g++ 6.3.1 and dockcross. The following works for me. I think the CMAKE_TOOLCHAIN_FILE is what matters.

```

cmake ../.. -DCMAKE_BUILD_TYPE=Release -DgRPC_INSTALL=ON -DCMAKE_TOOLCHAIN_FILE=${CMAKE_TOOLCHAIN_FILE} -DBUILD_SHARED_LIBS=ON -DgRPC_SSL_PROVIDER=package

make

```

Thank you very mush,i have make success.

```my toolChain.cmake

vim /tmp/toolChain.cmake

SET(CMAKE_SYSTEM_NAME Linux)

SET(CMAKE_SYSTEM_PROCESSOR arm)

# specify the cross compiler

set(GCC_COMPILER_PATH /prebuilts/gcc/linux-x86/arm/gcc-arm-8.3-2019.03-x86_64-arm-linux-gnueabihf)

set(CMAKE_C_COMPILER ${GCC_COMPILER_PATH}/bin/arm-linux-gnueabihf-gcc)

set(CMAKE_CXX_COMPILER ${GCC_COMPILER_PATH}/bin/arm-linux-gnueabihf-g++)

# where is the target environment 

#SET(CMAKE_FIND_ROOT_PATH  ${GCC_COMPILER_PATH})

# search for programs in the build host directories (not necessary)

SET(CMAKE_FIND_ROOT_PATH_MODE_PROGRAM NEVER)

# for libraries and headers in the target directories

SET(CMAKE_FIND_ROOT_PATH_MODE_LIBRARY ONLY)

SET(CMAKE_FIND_ROOT_PATH_MODE_INCLUDE ONLY)

```

```create file and make 

mkdir grpc/build

mkdir /tmp/grpc_arm

cd grpc/build

cmake .. -DCMAKE_BUILD_TYPE=Release -DgRPC_INSTALL=ON       -DCMAKE_INSTALL_PREFIX=/tmp/grpc_arm -DCMAKE_TOOLCHAIN_FILE=/tmp/toolChain.cmak

make -j

sudo make install

```
