###Building Google Protobuf 2.5.0

1. Download Protobuf source code:

   cd /<source_root>/
   wget https://github.com/google/protobuf/releases/download/v2.5.0/protobuf-2.5.0.tar.gz
   tar zxvf protobuf-2.5.0.tar.gz
   cd protobuf-2.5.0

2. Retrieve a generic header file from the official repository (available since version 2.6.0):

   wget https://raw.githubusercontent.com/google/protobuf/master/src/google/protobuf/stubs/atomicops_internals_generic_gcc.h -P src/google/protobuf/stubs/ 

3. Edit file src/google/protobuf/stubs/atomicops.h, navigate to line 184, add the following lines:

   #elif defined(GOOGLE_PROTOBUF_ARCH_S390)
   #include <google/protobuf/stubs/atomicops_internals_generic_gcc.h>

4. Edit file protobuf-2.5.0/src/google/protobuf/stubs/platform_macros.h, navigate to line 59, add the following lines:

   #elif defined(__s390x__)
   #define GOOGLE_PROTOBUF_ARCH_S390 1
   #define GOOGLE_PROTOBUF_ARCH_64_BIT 1

5. Configure the program, and run GNU make to build and install the binaries (please consult official build documentation for detailed configuration https://github.com/google/protobuf/blob/master/INSTALL.txt):

   ./configure
   make
   make check
   make install

6. Verify the installation

   export LD_LIBRARY_PATH=/usr/local/lib
   protoc --version

   Note: Protobuf should report version libprotoc 2.5.0
