c++头文件include问题 #583

Closed wangzhankun closed 5 years ago

wangzhankun commented 5 years ago

注：提问题时若使用不能用/没效果/有问题/报错此类模糊表达，但又没有根据下面的模板给出任何相关辅助信息的，将绝对不会有任何反馈。

描述问题

第一次使用xmake，同时对工程项目本身不太了解。该工程通过cmake编译无误。但是使用xmake编译自己的工程时，出现了下面的问题： image 下面是我的配置

target("myrm")
    set_kind("binary")
    add_files("src/*.cpp")
    on_load(function (target)
        import("lib.detect.find_package")
        target:add(find_package("pthread"))
        target:add(find_package("OpenCV"))
        target:add(find_package("gxiapi"))
        end)

下图是我的目录树： image 请问是哪里出错了呢？ 我看给出的例子里面也没有include相关的头文件的信息。另一方面，不知道我的第三方库引入是否正确。 谢谢。

你没加相关includes路径，请看下相关文档：https://xmake.io/#/zh-cn/manual/project_target?id=targetadd_includedirs

pthread这种系统库，直接可以通过add_syslinks来加就行了，可以看下文档：https://xmake.io/#/zh-cn/manual/project_target?id=targetadd_syslinks

其他第三方库的查找，可以使用你刚设置的方式，也可以通过find_packages来一次查找多个：

on_load(function (target)
    target:add(find_packages("xxx", "bbb"))
end)

你也可以手动执行 xmake l find_packages xxx ，如果没找到，就是系统没安装相关库，或者库名不对。

关于find_packages的详细使用描述，可以看下文档：https://xmake.io/#/zh-cn/package/system_package?id=查找系统包 （文档我刚更新过了）

你也可以使用add_requires来直接集成依赖库，具体看下文档：https://xmake.io/#/zh-cn/package/remote_package

非常感谢你的回复。现在可以编译了。但是在链接时不知道为啥无法link OpenCV。但是xmake可以找到OpenCV。 image 部分报错如下：

你可以找下错误提示中 cv::Mat cv::String 这些符号所在的库，是哪个，是否在find_packages的links里，如果在，确认下链接的依赖顺序是否正确。

你可以找下错误提示中 cv::Mat cv::String 这些符号所在的库，是哪个，是否在find_packages的links里，如果在，确认下链接的依赖顺序是否正确。 非常感谢，问题解决了，确实是链接顺序的问题。请问在哪里我可以找到有关链接顺序问题的说明呢。我应该如何配置呢？我是把配置更改如下才编译成功的：

add_syslinks("pthread", "gxiapi")
target("myrm")
set_kind("binary")
set_optimize("fastest")
add_includedirs("include")
add_files("src/*.cpp")
on_load(function (target)
import("lib.detect.find_package")
target:add(find_package("opencv"))
end)
waruqi commented 5 years ago

add_links/add_syslinks 内部根据添加顺序作为依赖顺序

add_syslinks 作为系统库，链接顺序在 所有 add_links之后

find_packages里面默认跟add_links的行为一致，就看哪个先添加了

on_load(function (target)
    target:add("syslinks", "pthread")
    target:add("links", "xxx", "zzz")
    target:add(find_packages("yyy"))
end)

根据添加顺序来作为links顺序, -lxxx -lzzz -lyyy -lpthread

请问为啥相同的配置，release能正常编译链接生成，debug模式又出现了无法链接OpenCV的情况呢？有关release和debug模式的切换是通过xmake的vscode插件完成的。 更改了配置可以正常编译，release和debug都可以。不知道为啥。 正确配置：

add_syslinks("pthread", "gxiapi")
add_requires("opencv")
target("myrm")
    set_kind("binary")
    set_optimize("fastest")
    add_includedirs("include")
    add_files("src/*.cpp")
    -- on_load(function (target)
    --     import("lib.detect.find_package")
    --     target:add(find_package("opencv"))
    --     end)
    add_packages("opencv")

报错配置如下：

add_syslinks("pthread", "gxiapi")
target("myrm")
    set_kind("binary")
    set_optimize("fastest")
    add_includedirs("include")
    add_files("src/*.cpp")
    on_load(function (target)
        import("lib.detect.find_package")
        target:add(find_package("opencv"))
        end)

报错如下：

debug/release只跟xmake.lua里面add_rules("mode.debug", "mode.release")的设置有关，只影响编译优化选项，如果xmake.lua没有加这个设置，是否切到debug/release效果都是一样的。。

你可以自己敲 -v 编译，获取完整编译，链接参数，作对比分析，理论上不会影响链接顺序，如果有符号链接不到，通过-v编译链接，查看完整link命令，对比分析下实际的link顺序是否ok
