The Windows build script uses static linking by default, the reason being that some tests were failing to build otherwise, mostly due to unspecified dependencies. Now that the issue was addressed, we can enable dynamic linking by default. Worth mentioning that the Ceph MSI build script already uses dynamic linking. While at it, we'll drop some duplicate defaults from "win32_deps_build.sh". For better clarity, we'll avoid exporting some "win32_build.sh" variables, instead passing them explicitly to "win32_deps_build.sh". Signed-off-by: Lucian Petrut <lpetrut@cloudbasesolutions.com>

About

|
-----
|
|
|
|
The Ceph client tools and libraries can be natively used on Windows. This avoids
|
|
the need of having additional layers such as iSCSI gateways or SMB shares,
|
|
drastically improving the performance.

|
|
Building
|
|
--------
|
|
|
|
At the moment, mingw gcc >= 8 is the only supported compiler for building ceph
|
|
components for Windows. Support for msvc and clang will be added soon.
|
|
|
|
`win32_build.sh`_ can be used for cross compiling Ceph and its dependencies.
|
|
It may be called from a Linux environment, including Windows Subsystem for
|
|
Linux. MSYS2 and CygWin may also work but those weren't tested.
|
|
|
|
This script currently supports Ubuntu 20.04 and openSUSE Tumbleweed, but it
|
|
may be easily adapted to run on other Linux distributions, taking into
|
|
account different package managers, package names or paths (e.g. mingw paths).
|
|
|
|
.. _win32_build.sh: win32_build.sh
|
|
|
|
The script accepts the following flags:
|
|
|
|
================= =============================== ===============================
|
|
Flag Description Default value
|
|
================= =============================== ===============================
|
|
OS Host OS distribution, for mingw ubuntu (also valid: suse)
|
|
and other OS specific settings.
|
|
TOOLCHAIN Mingw toolchain: mingw-llvm or mingw-llvm
|
|
mingw-gcc.
|
|
CEPH_DIR The Ceph source code directory. The same as the script.
|
|
BUILD_DIR The directory where the $CEPH_DIR/build
|
|
generated artifacts will be
|
|
placed.
|
|
DEPS_DIR The directory where the Ceph $CEPH_DIR/build.deps
|
|
dependencies will be built.
|
|
NUM_WORKERS The number of workers to use The number of vcpus
|
|
when building Ceph. available
|
|
CLEAN_BUILD Clean the build directory.
|
|
SKIP_BUILD Run cmake without actually
|
|
performing the build.
|
|
SKIP_TESTS Skip building Ceph tests.
|
|
SKIP_ZIP If unset, we'll build a zip
|
|
archive containing the
|
|
generated binaries.
|
|
ZIP_DEST Where to put a zip containing $BUILD_DIR/ceph.zip
|
|
the generated binaries.
|
|
EMBEDDED_DBG_SYM By default, the generated
|
|
archive will contain a .debug
|
|
subfolder, having the debug
|
|
symbols. If this flag is set,
|
|
the debug symbols will remain
|
|
embedded in the executables.
|
|
ENABLE_SHARED Dynamically link Ceph libs. ON
|
|
================= =============================== ===============================
|
|
|
|
The following command will build the binaries and add them to a zip archive
|
|
along with all the required DLLs. By default, the debug symbols are extracted
|
|
from the binaries and placed in the ".debug" folder of the archive.
|
|
|
|
.. code:: bash
|
|
|
|
SKIP_TESTS=1 ./win32_build.sh
|
|
|
|
In order to disable a flag, such as ``CLEAN_BUILD``, leave it undefined.
|
|
|
|
``win32_build.sh`` will fetch dependencies using ``win32_deps_build.sh``. If
|
|
all dependencies are successfully prepared, this potentially time consuming
|
|
step will be skipped by subsequent builds. Be aware that you may have to do
|
|
a clean build (using the ``CLEAN_BUILD`` flag) when the dependencies change
|
|
(e.g. after switching to a more recent Ceph version by doing a ``git pull``).
|
|
|
|
Make sure to explicitly pass the "OS" parameter when directly calling
|
|
``win32_deps_build.sh``. Also, be aware of the fact that it will use the distro
|
|
specific package manager, which will require privileged rights.

|
Installing
|
|
----------
|
|
|
|
MSI installer
|
|
=============
|
|
|
|
Using the MSI installer is the recommended way of installing Ceph on Windows.
|
|
Please check the `installation guide`_ for more details.
|
|
|
|
Manual installation
|
|
===================
|
|
|
|
In order to manually install ``ceph``, start by unzipping the
|
|
binaries that you may have obtained by following the building_ step.
|
|
|
|
You may want to update the environment PATH variable, including the Ceph
|
|
path. Assuming that you've copied the Ceph binaries to ``C:\Ceph``, you may
|
|
use the following Powershell command:
|
|
|
|
.. code:: bash
|
|
|
|
[Environment]::SetEnvironmentVariable("Path", "$env:PATH;C:\ceph", "Machine")
|
|
|
|
In order to mount Ceph filesystems, you will have to install Dokany.
|
|
You may fetch the installer as well as the source code from the Dokany
|
|
Github repository: https://github.com/dokan-dev/dokany/releases
|
|
|
|
Make sure to install Dokany 2.0.5 or later.
|
|
|
|
In order to map RBD images, the ``WNBD`` driver must be installed. Please
|
|
check out this page for more details about ``WNBD`` and the install process:
|
|
https://github.com/cloudbase/wnbd
|
|
|
|
The following command can be used to configure the ``ceph-rbd`` service.
|
|
Please update the ``rbd-wnbd.exe`` path accordingly.
|
|
|
|
.. code:: PowerShell
|
|
|
|
New-Service -Name "ceph-rbd" `
|
|
-Description "Ceph RBD Mapping Service" `
|
|
-BinaryPathName "c:\ceph\rbd-wnbd.exe service" `
|
|
-StartupType Automatic
