How can I successfully Build gRPC in C++? - c++

Question

I am trying to build gRPC in C++ by following c++ gRPC installation. My OS is Ubuntu20.4 LTS installed on Raspberry Pi 4.
When I typed this command "make -j"
$ cd grpc
$ mkdir -p cmake/build
$ pushd cmake/build
$ cmake -DgRPC_INSTALL=ON \
-DgRPC_BUILD_TESTS=OFF \
-DCMAKE_INSTALL_PREFIX=$MY_INSTALL_DIR \
../..
$ make -j
this error occurs.

Please help me to fix this problem.

Can you show what value the gRPC_SSL_PROVIDER variable has? If has module than you just init submodules and build with BoringSSL (see and see). Another option, you can build with OpenSSL, just set -DgRPC_SSL_PROVIDER=package.
