在项目中使一些源文件不使用预编译头 #5960

fengjinfuyl · 2024-12-12T10:38:24Z

你在什么场景下需要该功能？

一般项目所有源文件都会用到编译头，然而有个别源文件不想使用。在vs中，独立选中某个cpp可以设计不使用编译头。xmake我看到可以设置单个文件的编译选项，但我不知道不使用预编译头的编译选项是什么，搜索议题与社区也未发现有。

描述可能的解决方案

CMAKE中似乎是使用SKIP_PRECOMPILE_HEADERS附加到cpp附属来做的。

描述你认为的候选方案

加个命令add_skip_pch_sources()?

Title: Make some source files in the project not use precompiled headers

In what scenario do you need this function?

Generally, all source files in a project will use the compiled header, but some source files do not want to be used. In VS, you can design a cpp independently without using the compiled header. I saw that xmake can set the compilation options of a single file, but I don’t know what the compilation options are without using precompiled headers, and I didn’t find any by searching the issues and communities.

Describe possible solutions

CMAKE seems to be done by using SKIP_PRECOMPILE_HEADERS attached to the cpp attachment.

Describe your alternatives

Add a command add_skip_pch_sources()?

/Y- 可禁用

Issues-translate-bot · 2024-12-12T10:52:39Z

/Y- can be disabled

add_files("xxx.cpp",{cxxflags="/Y-"})，没有效果

Issues-translate-bot · 2024-12-13T01:17:46Z

add_files("xxx.cpp",{cxxflags="/Y-"}), has no effect

waruqi · 2024-12-20T02:50:30Z

这边测试可以的么，/Y- 加进去了，并且编译到 test7.cpp 明显停滞变慢了。

add_rules("mode.debug", "mode.release")

target("main")
    set_kind("binary")
    set_languages("cxx11")
    set_pcxxheader("src/header.h")
    add_files("src/test7.cpp", {cxflags = "/Y-"})
    add_files("src/*.cpp|test7.cpp", "src/*.c", "*.cpp")

Issues-translate-bot · 2024-12-20T02:50:44Z

Is it possible to test here? /Y- has been added, and the compilation to test7.cpp has obviously stalled and slowed down.

add_rules("mode.debug", "mode.release")

target("main")
    set_kind("binary")
    set_languages("cxx11")
    set_pcxxheader("src/header.h")
    add_files("src/test7.cpp", {cxflags = "/Y-"})
    add_files("src/*.cpp|test7.cpp", "src/*.c", "*.cpp")

fengjinfuyl · 2024-12-20T03:19:42Z

看到同时有/Y- 和YU，不知道/Y-到底起效没有;我之前是通过转换成sln后，查看cpp对应属性页，发现还是使用预编译头，且对应的命令行中没找到/Y-选项。你所说明显停滞变慢了可能只是感觉，可能还需要验证下。

Issues-translate-bot · 2024-12-20T03:19:54Z

I saw /Y- and YU at the same time, and I don’t know if /Y- is effective. I checked the corresponding property page of cpp after converting it to sln, and found that the precompiled header was still used, and the corresponding command line was not found. /Y-option. The obvious stagnation and slowdown you said may just be a feeling, and it may need to be verified.

用这个 patch 的进程性能耗时统计特性，来提供数据验证。

结果

可以看到，add_files("src/test7.cpp", {cxflags = "/Y-"}) 之后，test7.cpp 的编译，明显排到了 top2，占了总时间的 19.2% ，仅次于 header.h 预处理头文件的编译的耗时，而没添加前，每个 cpp 的编译耗时分布都是均匀分布的。

所以，有数据验证确认，目前的配置就是生效的。

不要用生成 sln 来验证，那个不支持

result

It can be seen that after add_files("src/test7.cpp", {cxflags = "/Y-"}), the compilation of test7.cpp is obviously ranked top2, accounting for 19.2% of the total time, second only to header.h preprocesses the compilation time of the header file. Before adding it, the compilation time of each cpp is evenly distributed.

Therefore, with data verification and confirmation, the current configuration will take effect.

Issues-translate-bot · 2024-12-20T04:04:52Z

Do not use generate sln for verification, that is not supported

fengjinfuyl · 2024-12-23T02:52:25Z

实测加入了/Y-后，预编译头还是起效了，

add_rules("mode.debug", "mode.release")
set_languages("c++17")
target("pchtest")
    set_kind("binary")
    add_files("src/main.cpp",{force={cxflags="/Y-"}})
    set_pcxxheader("src/pch.h")

// main.cpp
#include <iostream>

#ifdef PCH_TEST
const int a = 0;
#else
const int a = 1;
#endif

int main(int argc, char **argv) {
  std::cout << "a  is " << a << std::endl;
  return 0;
}

#ifndef PCH_H
#define PCH_H

#define PCH_TEST

#endif

下述生成命令中/Y-已经加入

"C:\\Program Files\\Microsoft Visual Studio\\2022\\Enterprise\\VC\\Tools\\MSVC\\14.42.34433\\bin\\HostX64\\x64\\cl.exe" -c -nologo -Zi -FS -Fdbuild\windows\x64\debug\compile.pchtest.pdb -Od -std:c++17 /EHsc -YuE:\Repo\pchtest\build\.gens\pchtest\windows\x64\debug\src\pch.h -FIE:\Repo\pchtest\build\.gens\pchtest\windows\x64\debug\src\pch.h -Fpbuild\.objs\pchtest\windows\x64\debug\gens\src\cxx\pch.h_v143.pch /Y- -Fobuild\.objs\pchtest\windows\x64\debug\src\main.cpp.obj src\main.cpp

然而打印结果，a总为0

Issues-translate-bot · 2024-12-23T02:52:36Z

Actual testing shows that after adding /Y-, the precompiled header still works.

add_rules("mode.debug", "mode.release")
set_languages("c++17")
target("pchtest")
    set_kind("binary")
    add_files("src/main.cpp",{force={cxflags="/Y-"}})
    set_pcxxheader("src/pch.h")

// main.cpp
#include <iostream>

#ifdef PCH_TEST
const int a = 0;
#else
const int a = 1;
#endif

int main(int argc, char **argv) {
  std::cout << "a is " << a << std::endl;
  return 0;
}

#ifndef PCH_H
#define PCH_H

#define PCH_TEST

#endif

In the following generation command, /Y- has been added

"C:\\Program Files\\Microsoft Visual Studio\\2022\\Enterprise\\VC\\Tools\\MSVC\\14.42.34433\\bin\\HostX64\\x64\\cl.exe" -c - nologo -Zi -FS -Fdbuild\windows\x64\debug\compile.pchtest.pdb -Od -std:c++17 /EHsc -YuE:\Repo\pchtest\build\.gens\pchtest\windows\x64\debug\src\pch.h -FIE:\Repo\pchtest\build\.gens\pchtest\ windows\x64\debug\src\pch.h -Fpbuild\.objs\pchtest\windows\x64\debug\gens\src\cxx\pch.h_v143.pch /Y- -Fobuild\.objs\pchtest\windows\x64\debug\src\main.cpp.obj src \main.cpp

However, when printing the result, a is always 0

waruqi · 2024-12-24T02:01:58Z

加 /Y- 只是禁止预编译。。force include 还是取消不掉的，不编译预编译头。。但还是会 force include src/pch.h ，你改了 pch.h ，就肯定还是会获取到改动后的 macros value

但预编译确实应该已经禁用了。

Issues-translate-bot · 2024-12-24T02:47:51Z

Adding /Y- just disables precompilation. . Force include still cannot be canceled and the precompiled header will not be compiled. . But it will still force include src/pch.h. If you change pch.h, you will definitely still get the modified macros value.

But precompilation should indeed be disabled.

fengjinfuyl · 2024-12-24T05:12:09Z

如何能够取消force include，msvc中一个cpp不使用预编译头文件时，我看他的完整编译选项中好像不会引入预编译头文件啊。

Cannot be canceled unless you do not set precompilation

fengjinfuyl · 2024-12-25T00:23:11Z

cmake_minimum_required(VERSION 3.5) project("pchtest") set_source_files_properties("src/main.cpp" PROPERTIES SKIP_PRECOMPILE_HEADERS ON) add_executable("pchtest" "src/main.cpp") target_precompile_headers("pchtest" PRIVATE "src/pch.h") CMake设置SKIP_PRECOMPILE_HEADERS属性可以不强制包含预编译头文件我感觉可以有两种方式改进，一种是像CMAKE这样，在configs上加，使得可以 add_files("xxx.cpp",{configs={"skippch"=true}})这样来取消预编译，且不强制包含。第二种是像我开头说的那样，是否可以增加一行 add_skippch_files(“xx.cpp","xx1.cpp") 1121443108 ***@***.***
