Overview
This is protobuf-c, a C implementation of Google Protocol Buffers. It includes libprotobuf-c, a pure C library that implements protobuf encoding and decoding, and protoc-c, a code generator that converts Protocol Buffer .proto files to C descriptor code, based on the original protoc. It also includes libprotobuf-c-rpc, a separate library for performing RPC with Protocol Buffers.
protobuf-c was originally maintained by Dave Benson through version 0.15 but is now being maintained by a new team. Thanks, Dave!
Building
protobuf-c requires a C compiler, a C++ compiler, Google Protocol Buffers, and pkg-config to be installed.
./configure && make && make install
If building from a git checkout, the autotools (autoconf, automake, libtool) must also be installed, and the build system must be generated by running the autogen.sh script.
./autogen.sh && ./configure && make && make install
The libprotobuf-c-rpc library is included in the source distribution but is not built by default. Add --enable-rpc to the configure command to enable this library.
Synopsis
Include the protobuf-c header file:
#include <protobuf-c/protobuf-c.h>
Link against the protobuf-c library.
-lprotobuf-c
libprotobuf-c includes a pkg-config file. It is recommended to use the pkg-config system in order to determine the complete set of compiler and linker flags for building applications that utilize libprotobuf-c. If using pkg-config with autoconf, the PKG_CHECK_MODULES macro can be used to detect the presence of libprotobuf-c:
PKG_CHECK_MODULES([PROTOBUF_C], [libprotobuf-c])
This will place compiler flags in the PROTOBUF_C_CFLAGS variable and linker flags in the PROTOBUF_C_LDFLAGS variable.
(Note that the protobuf-c header file used to be installed as google/protobuf-c/protobuf-c.h in previous versions.)
