ceph踩坑记

编译ceph

Ubuntu20.04使用clang-13编译ceph(quincy)时，出现了找不到C++20头文件的情况

ceph/src/include/denc.h:30:10: fatal error: 'concepts' file not found
#include <concepts>

参考这里
问题解决：sudo apt install g++-10。

编译 radosgw

编译rgw_file_marker时报错

错误信息同BUILD_ERROR.txt.

解决方法: 合入nautilus: test/ceph_test_librgw_file*: Remove duplicate names #43491这个PR。

调试相关

使用lldb 进行debug时，无法解析字符串

error: summary string parsing error

需要在CMakeLists.txt中添加:

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -fstandalone-debug")

vscode 编译参数记录

// 修改settings.json
{
    "cmake.generator": "Unix Makefiles",
    "clangd.path": "clangd-13",
    "cmake.configureArgs": [
            "-DWITH_MGR_DASHBOARD_FRONTEND=OFF",
