Compiling libprotobuf

Examples for compiling a 32-bit libprotobuf and other protobuf libraries using the protobuf-2.3.0 source.

Windows

The following was tested on Windows 7 with Visual Studio 2010. Not all projects built after conversion, but only libprotobuf and dependencies were necessary.

• Download protobuf-2.3.0.zip from https://code.google.com/p/protobuf/downloads/list
• Extract and navigate to protobuf-2.3.0/vsprojects/
• Open protobuf.sln in the version of Visual Studio corresponding with the VC abi version that you wish to compile for.
• Walk through project conversion steps if necessary.
• Right-click the libprotobuf project and choose properties.
• In Configuration Properties > C/C++ -> Code Generation, set Runtime Library to /MT for Release or /MTd for Debug.
• Right-click the libprotobuf project and choose Build.

libprotobuf.lib will be in Release/ or Debug/, depending on build configuration.

Linux (32-bit host)

The following was tested on Debian 6 (Lenny) 32-bit.

wget https://protobuf.googlecode.com/files/protobuf-2.3.0.tar.gz
tar -xvzf protobuf-2.3.0.tar.gz
cd protobuf-2.3.0
./configure
make

For a debug build, replace ./configure with:

./configure CXXFLAGS="-g3 -ggdb3"

This will also override protobuf's default CXXFLAGS of -DNDEBUG

The library will be in src/.libs/

Linux (64-bit host)

This hasn't been tested, but should work on most or all 64-bit distributions.

wget https://protobuf.googlecode.com/files/protobuf-2.3.0.tar.gz
tar -xvzf protobuf-2.3.0.tar.gz
cd protobuf-2.3.0
./configure --build=i686-pc-linux-gnu CFLAGS="-m32 -DNDEBUG" CXXFLAGS="-m32 -DNDEBUG" LDFLAGS=-m32
make

For a debug build, replace ./configure with:

./configure --build=i686-pc-linux-gnu CFLAGS="-m32" CXXFLAGS="-m32 -g3 -ggdb3" LDFLAGS=-m32

This will also override protobuf's default CXXFLAGS of -DNDEBUG

The library will be in src/.libs/

Mac

The following was tested on OS X 10.7 (Lion) and ensures that the outputted binaries are 32-bit.

wget https://protobuf.googlecode.com/files/protobuf-2.3.0.tar.gz
tar -xvzf protobuf-2.3.0.tar.gz
cd protobuf-2.3.0
./configure --build=x86-apple-darwin ABI=standard CFLAGS="-DNDEBUG -m32" CXXFLAGS="-m32 -DNDEBUG" LDFLAGS=-m32
make

For a debug build, replace ./configure with:

./configure --build=x86-apple-darwin ABI=standard CFLAGS="-m32" CXXFLAGS="-m32 -g3 -ggdb3" LDFLAGS=-m32

This will also override protobuf's default CXXFLAGS of -DNDEBUG

The library will be in src/.libs/
