build on MacOS¶
Since we’ve switched to C++ 17, and the default clang shipped with Xcode 9 does not support all the C++ 17 language features, it’s suggested to install clang using brew:
brew install --with-toolchain llvm
and install all the necessary bits:
brew install snappy ccache cmake pkg-config pip install cython
install FUSE if you want to build the FUSE support:
brew cask install osxfuse
then, under the source directory of Ceph:
mkdir build cd build cmake .. -DBOOST_J=4 \ -DCMAKE_C_COMPILER=/usr/local/opt/llvm/bin/clang \ -DCMAKE_CXX_COMPILER=/usr/local/opt/llvm/bin/clang++ \ -DCMAKE_EXE_LINKER_FLAGS="-L/usr/local/opt/llvm/lib" \ -DENABLE_GIT_VERSION=OFF \ -DWITH_MANPAGE=OFF \ -DWITH_LIBCEPHFS=OFF \ -DWITH_XFS=OFF \ -DWITH_KRBD=OFF \ -DWITH_LTTNG=OFF \ -DWITH_BABELTRACE=OFF \ -DWITH_BLUESTORE=OFF \ -DWITH_RADOSGW=OFF \ -DWITH_SPDK=OFF \ -DSNAPPY_ROOT_DIR=/usr/local/Cellar/snappy/1.1.7_1
The paths to
snappy might vary if newer versions of the packages are installed.
Also, please consider using boost v1.69 to address the bug of https://github.com/boostorg/atomic/issues/15.
Currently, the most practical uses for Ceph on MacOS might be FUSE and some other librados based applications.
