%general-entities; ]> Protobuf The Protobuf package contains utilities and libraries for using data in Google's data interchange format. &lfs121_checked; Package Information Download (HTTP): Download MD5 sum: &protobuf-md5sum; Download size: &protobuf-size; Estimated disk space required: &protobuf-buildsize; Estimated build time: &protobuf-time; Protobuf Dependencies Required and Optional gtest (for tests) Install Protobuf by running the following commands: mkdir build && cd build && cmake -DCMAKE_INSTALL_PREFIX=/usr \ -DCMAKE_BUILD_TYPE=Release \ -DCMAKE_SKIP_INSTALL_RPATH=ON \ -Dprotobuf_BUILD_TESTS=OFF \ -Dprotobuf_ABSL_PROVIDER=package \ -Dprotobuf_BUILD_LIBUPB=OFF \ -Dprotobuf_BUILD_SHARED_LIBS=ON \ -Dutf8_range_ENABLE_INSTALL=OFF \ -G Ninja .. && ninja This package does come with a test suite, but it requires gtest, which is not part of BLFS. Now, as the &root; user: sed 's/utf8_range//' -i *.pc && ninja install sed 's/utf8_range//' -i *.pc: This command removes a leftover reference to libutf8_range from the pkg-config files installed by this package. -Dprotobuf_BUILD_TESTS=OFF: This parameter prevents the tests from being built because gtest is not part of BLFS. -Dprotobuf_ABSL_PROVIDER=package: This parameter allows the build system to use the system-installed copy of . -Dprotobuf_BUILD_SHARED_LIBS=ON: This parameter enables building shared versions of the libraries provided by this package instead of static versions. -Dutf8_range_ENABLE_INSTALL=OFF: This parameter disables installing the utf8_range static library. The functions provided by this library and used by protobuf is already embedded into libprotobuf.so, so installing a full copy of the static library is just wasting the disk space.
