Build protobuf

If you would like to build protobuf from sources, you can use the following commands to obtain the source code repositories, configure, and build the code. On a Debian based system, you may have to install autoconf curl g++ libtool packages first.

Build protobuf

 cd deps
 git clone https://github.com/google/protobuf.git protobuf
 cd protobuf
 ./autogen.sh
 ./configure --prefix=`pwd`/../`uname -m`-linux-gnu
 make
 make install
 cd ../..

Build protobuf-c

 cd deps
 git clone https://github.com/protobuf-c/protobuf-c.git protobuf-c
 cd protobuf-c
 ./autogen.sh
 mkdir ../pbc-`uname -m`
 cd ../pbc-`uname -m`
 ../protobuf-c/configure --prefix=`pwd`/../`uname -m`-linux-gnu \
   PKG_CONFIG_PATH=`pwd`/../`uname -m`-linux-gnu/lib/pkgconfig
 make
 make install
 cd ../..

Cross-compile for ARM

ARMv7

 cd deps
 mkdir -p pbc-arm
 cd pbc-arm
 ../protobuf-c/configure --host=arm-linux-gnueabihf --prefix=`pwd`/../arm-linux-gnueabihf \
                         --disable-protoc PATH=`pwd`/../`uname -m`-linux-gnu/bin:$PATH
 make PATH=`pwd`/../`uname -m`-linux-gnu/bin:$PATH
 make install PATH=`pwd`/../`uname -m`-linux-gnu/bin:$PATH
 cd ../..

ARM8

 cd deps
 mkdir -p pbc-aarch64
 cd pbc-aarch64
  ../protobuf-c/configure --host=aarch64-linux-gnu --prefix=`pwd`/../aarch64-linux-gnu \
                          --disable-protoc PATH=`pwd`/../`uname -m`-linux-gnu/bin:$PATH
 make PATH=`pwd`/../`uname -m`-linux-gnu/bin:$PATH
 make install PATH=`pwd`/../`uname -m`-linux-gnu/bin:$PATH
 cd ../..
