Examples for compiling a 32-bit libprotobuf and other protobuf libraries using the protobuf-2.5.0 source.
For Dota 2, replace version 2.5.0 with 2.6.1.
Also note that the Protobuf source has moved to GitHub. Some of the below links may be outdated.
Windows
The following was tested on Windows 8.1 with Visual Studio 2013. Not all projects built after conversion, but only libprotobuf and dependencies were necessary.
- Download protobuf-2.5.0.zip from https://code.google.com/p/protobuf/downloads/list
- Extract and navigate to protobuf-2.5.0/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.
- If building the Debug configuration, also add _ITERATOR_DEBUG_LEVEL=0 in Configuration Properties > C/C++ > Preprocessor > Preprocessor Defintions
- 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-2.5.0.tar.gz tar -xvzf protobuf-2.5.0.tar.gz cd protobuf-2.5.0 ./configure make
For a debug build, replace ./configure with:
./configure CFLAGS="-fvisibility=hidden" 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-2.5.0.tar.gz tar -xvzf protobuf-2.5.0.tar.gz cd protobuf-2.5.0 ./configure --build=i686-pc-linux-gnu CFLAGS="-m32 -DNDEBUG -fvisibility=hidden" CXXFLAGS="-m32 -DNDEBUG" LDFLAGS=-m32 make
For a debug build, replace ./configure with:
./configure --build=i686-pc-linux-gnu CFLAGS="-m32 -fvisibility=hidden" 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-2.5.0.tar.gz tar -xvzf protobuf-2.5.0.tar.gz cd protobuf-2.5.0 ./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 -fvisibility=hidden" CXXFLAGS="-m32 -g3 -ggdb3" LDFLAGS=-m32
This will also override protobuf's default CXXFLAGS of -DNDEBUG
The library will be in src/.libs/
