Need Help on Cross compilation of GRPC.

[Neeli Srinivas]

Hi All,

This is Srinivas.  I am new to GRPC, I am trying to compile latest grpc (v1.7.2)  version.

It's working in X86 architecture. when i am trying to compile for ARM architecture(cortex A9) it's not working.

Please guide me the steps. One more thing  i am using protobuf 3.4.0 version. I am going to explain what i followed in below.

followed steps:

------------------ 

Environment Details:

1)linux 14.04 

2)uname -a :

    Linux aaa 3.13.0-135-generic #184-Ubuntu SMP Wed Oct 18 11:55:51 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux

steps:1

---------

-> Compiled for x86 

-> GRPC version V1.7.2

-> Protobuf 3.4.0

-> Compilation was success 

$ ./configure

$ make

$ make check

$ sudo make install

$ sudo ldconfig # refresh shared library cache.

 -> followed this link  https://github.com/google/protobuf/blob/master/src/README.md

 

Steps:2 (Trying to compile for ARM by using cross compiler)

---------- ---------------------------------------------------------------------

- Using cross compilers 

     arm-linux-gnueabi-gcc

     arm-linux-gnueabi-g++.

-> cd grpc

-> git submodule update --init

-> ./autogen.sh

-> ./configure  --host=arm-linux --with-protoc=/home/xxxx/grpc/third_party/protobuf/COMP/bin/protoc --prefix=/home/xxxx/grpc/third_party/protobuf/build

-> make 

-> make check

-> sudo make install

In this process i am getting in errors. while doing sudo make install facing issues. 

** Here My question is ?

 - What i am following is it correct or not ?

 - If my procedure wrong . please share me the correct procedure. 

-Advanced thanks

Thanks

What errors are you getting? It looks to me like in your step 2 you are trying to install cross-compiled code, and I would suspect this would be a problem since you would be installing code which is not built for the machine's architecture.

Thanks Adam for giving responce.

Today i tried same thing. i am getting error with that. I am sharing the procedure what i followed. please look at once.

- cloned grpc

- updated submodule

- exporting corss compiler  

- cd /grpc/third_party/protobuf/

- /grpc/third_party/protobuf$ ./autogen.sh

- make HAS_PKG_CONFIG=false CC=arm-linux-gcc CXX=arm-linux-g++  RANLIB=arm-linux-ranlib LD=arm-linux-ld LDXX=arm-linux-g++ AR=arm-linux-gcc-ar PROTOBUF_CONFIG_OPTS="--host=arm-linux --with-protoc=/usr/local/bin/protoc --prefix=/home/srinin3/OUT_PUT" static

I tried above things. after this my error is

[MAKE]    Generating cache.mk

[AR]      Creating /home/srinin3/grpc/libs/opt/libares.a

sorry - this program has been built without plugin support

make: *** [/home/srinin3/grpc/libs/opt/libares.a] Error 1

Could you please tell me the process for resolving this issue.

Thanks

It looks like the part of the build that's failing is related to gRPC and not protobuf, right? You might want to ask about this on the gRPC mailing list.
