Building Google Protocol Buffers and SDHash on Ubuntu 16.04

ubuntu_sdhash.md

Install Protobuf 2.5

Install protobufs from source. If you try to use a newer version, you'll run into an error related to kEmptyString.

sudo apt-get install autoconf automake libtool curl make g++ unzip
wget https://github.com/google/protobuf/archive/v2.5.0.tar.gz
tar -zxvf v2.5.0.tar.gz
cd protobuf-2.5.0/

This is where the hacks start. protobuf depends on Google Mock, which has since been merged into Google Test. This evolution causes a few issues when getting protobuf 2.5 compiled and running make check.

First, replace the 2.5.0 autogen.sh with the current:

wget https://raw.githubusercontent.com/google/protobuf/bba446bbf2ac7b0b9923d4eb07d5acd0665a8cf0/autogen.sh

Next is to fix configure.ac to point to the new Google Mock. Modify Line 147 to read:

AC_CONFIG_SUBDIRS([gmock])

and fix the make check directive in Makefile.am my modifying Lines 20-21 to read:

	@echo "Making lib/libgmock.a lib/libgmock_main.a in gmock"
	@cd gmock && $(MAKE) $(AM_MAKEFLAGS) lib/libgmock.la lib/libgmock_main.la
	@cd gmock/gtest && $(MAKE) $(AM_MAKEFLAGS) lib/libgtest.la lib/libgtest_main.la

Now we're ready:

./autogen.sh
ln -s gmock/gtest gtest
./configure
make
make check

To support uninstall, we use checkinstall, which will build .deb and run make install.

sudo apt-get install checkinstall
sudo checkinstall -y
sudo ldconfig

Install sdhash from source

wget https://github.com/sdhash/sdhash/archive/v4.0.tar.gz
tar -zxvf v4.0.tar.gz
cd sdhash-4.0
make
sudo checkinstall -y

To build and test python bindings:

sudo apt-get install swig libboost-dev 
make swig-py
cd swig/python/
python test.py
