.. _compile_fcitx5: ==================== 编译fcitx5 ==================== .. warning:: 由于时间精力有限，我没有完成 :ref:`raspberry_pi_os` 环境编译fcitx5 。不过，可能根据 `Debian 9 testing 下安装 fcitx5 `_ 文档，应该是能够完成编译的。 我走了不少弯路，这里文章仅供归档参考，后续有时间精力再完善。目前我改为直接使用发行版提供二进制软件包。 在 :ref:`raspberry_pi_os` 环境编译fcitx5 准备 ======== - 安装编译依赖工具:: sudo apt install gcc g++ cmake extra-cmake-modules make \ libxcb1 libxcb1-dev libxcb-util1 libxcb-util-dev libxcb-keysyms1 libxcb-keysyms1-dev \ expat pkg-config libjson-c-dev dbus libfmt-dev 上述列表可能不全，我现在没有时间再继续探索，建议参考 `Debian 9 testing 下安装 fcitx5 `_ :: sudo apt install build-essential cmake extra-cmake-modules libxcb1-dev \ libxcb-keysyms1-dev libxcb-util0-dev libdbus-1-dev libevent-dev uuid-dev \ gettext libsystemd-dev libxkbfile-dev libxkbcommon-x11-dev libxcb-xkb-dev \ libxcb1-dev libpango1.0-dev libpangocairo-1.0-0 libenchant-dev libxcb-ewmh-dev \ libxcb-xinerama0-dev libxcb-icccm4-dev libxcb-ewmh-dev wayland-protocols \ libboost-dev libcurl4-gnutls-dev libopencc-dev qt5libwebengine5-dev \ libqt5webchannel5-dev qt4-qmake libqt4-dev qtbase5-dev libboost-iostreams-dev \ gobject-introspection libgirepository1.0-dev libgtk2.0-dev libgtk-3-dev 编译 ======= xcb-imdkit -------------- 编译 ``xcb-imdkit`` 需要安装:: ``libxcb, xcb-util, xcb-util-keysym`` :: sudo apt install libxcb1 libxcb1-dev libxcb-util1 libxcb-util-dev libxcb-keysyms1 libxcb-keysyms1-dev - 编译安装 ``xcb-imdkit`` :: git clone https://github.com/fcitx/xcb-imdkit.git cd xcb-imdkit cmake . make sudo make install emoji(未安装支持) -------------------- 我不使用emoji，所以后续编译 fcitx5 使用参数 ``-DENABLE_EMOJI=Off`` fcitx5 ---------- - 下载fcitx源代码:: git clone https://github.com/fcitx/fcitx5.git - 编译需要依赖 ``libevent`` :: sudo apt install libevent-dev libevent ~~~~~~~~~~~ 但是fcitx5 ``cmake`` 报错:: CMake Warning at CMakeLists.txt:86 (find_package): By not providing "FindLibevent.cmake" in CMAKE_MODULE_PATH this project has asked CMake to find a package configuration file provided by "Libevent", but CMake did not find one. Could not find a package configuration file provided by "Libevent" with any of the following names: LibeventConfig.cmake libevent-config.cmake 参考 `cmake链接libevent的问题 `_ ，确实通过 ``apt install libevent-dev`` 没有安装过上述文件，在debian官方包搜索也找不到，所以还是改为从源代码编译安装 ``libevent`` :: sudo apt purge libevent-dev sudo apt autoremove # 编译libevent 依赖 ssl，mbedtls 所以先安装 sudo apt install libssl-dev libmbedtls-dev git clone https://github.com/libevent/libevent.git cd libevent mkdir build && cd build cmake .. 这里有报错，检查 ``CMakeFiles/CMakeError.log`` 有如下错误:: /home/huatai/fcitx5/libevent/build/CMakeFiles/CheckIncludeFiles/EVENT__HAVE_PORT_H.c:22:10: fatal error: port.h: No such file or directory 22 | #include | ^~~~~~~~ compilation terminated. gmake[1]: *** [CMakeFiles/cmTC_79256.dir/build.make:85: CMakeFiles/cmTC_79256.dir/EVENT__HAVE_PORT_H.c.o] Error 1 在源代码 ``evport.c`` 中有:: #include 根据 ``configure.ac`` 内容:: AC_CHECK_HEADERS([arpa/inet.h fcntl.h ifaddrs.h mach/mach_time.h mach/mach.h netdb.h netinet/in.h netinet/in6.h netinet/tcp.h sys/un.h poll.h port.h stdarg.h stddef.h sys/devpoll.h sys/epoll.h sys/event.h sys/eventfd.h sys/ioctl.h sys/mman.h sys/param.h sys/queue.h sys/resource.h sys/select.h sys/sendfile.h sys/socket.h sys/stat.h sys/time.h sys/timerfd.h sys/uio.h sys/wait.h sys/random.h errno.h afunix.h]) 可以看到，所有头文件默认都是在 ``/usr/include`` ，例如 ``/usr/include/arpa/inet.h`` 也就是需要访问 ``/usr/include/port.h`` ，这是哪个软件包提供的？从 https://packages.debian.org/search 无法找到 - 所以采用 :ref:`apt-file` :: sudo apt install apt-file sudo apt-file update 尝试搜索:: apt-file search /usr/include/port.h 没有结果 而 ``poll.h`` 则是 ``libc6-dev`` 提供的 从系统来看，目前只默认安装了 ``/usr/include/brotli/port.h`` ( ``libbrotli-dev`` LZ77压缩解压缩库) 真是一个问题带出另一个问题... 不过，确实可以从 ``libevent`` 源代码中找到 ``LibeventConfig.cmake`` ，看来从源代码安装是会包含这个文件的，应该能够满足 fcitx5 编译需求。 尝试了一下在ubuntu环境中安装 ``libevent-dev`` 可以看到会依赖安装:: libevent-core-2.1-7 libevent-extra-2.1-7 libevent-openssl-2.1-7 libevent-pthreads-2.1-7 - 继续:: make make verify # (optional) fcitx5(继续) -------------- - 编译 - 关闭了wayland , 关闭 enchant(基于abiword的拼写检查) , 关闭 emoji :: cd fcitx5 cmake -DENABLE_WAYLAND=Off -DENABLE_ENCHANT=off -DENABLE_EMOJI=Off . 这里报错:: CMake Warning at CMakeLists.txt:86 (find_package): By not providing "FindLibevent.cmake" in CMAKE_MODULE_PATH this project has asked CMake to find a package configuration file provided by "Libevent", but CMake did not find one. Could not find a package configuration file provided by "Libevent" with any of the following names: LibeventConfig.cmake libevent-config.cmake Add the installation prefix of "Libevent" to CMAKE_PREFIX_PATH or set "Libevent_DIR" to a directory containing one of the above files. If "Libevent" provides a separate development package or SDK, be sure it has been installed. 解决方法增加参数 ``-DCMAKE_PREFIX_PATH=/usr/include/event2`` ? 参考 ======= - `Compiling fcitx5 `_ - `How to set the CMAKE_PREFIX_PATH? `_ - `Debian 9 testing 下安装 fcitx5 `_ - 这篇文章详细提供了编译安装，后续如果编译，可以参考这篇文档
