error: attempt to concatenate local 'p' (a nil value) #933

Closed pchuan98 closed 4 years ago

pchuan98 commented 4 years ago

我在Windows10，Qt15.14.2，VSCode下，先使用xmake自动生成的Qt项目，但是在编译过程中一直出现

C:\Users\adm\Desktop\untitled4\demo\test>xmake f -p mingw --sdk=C:\Qt\Qt5.14.2\Tools\mingw730_64 -P .
checking for the architecture ... x86_64
checking for the mingw directory ... C:\Qt\Qt5.14.2\Tools\mingw730_64
error: attempt to concatenate local 'p' (a nil value)

这种问题，请问是我什么位置没有配置好么？还是命令输入有问题？ 这是默认生成的detect文件

"
{
    ["detect.sdks.find_mingw"] = {
        mingw = {
            cross = "x86_64-w64-mingw32-",
            sdkdir = [[C:\Qt\Qt5.14.2\Tools\mingw730_64]],
            bindir = [[C:\Qt\Qt5.14.2\Tools\mingw730_64\bin]]
        }
    },
    ["detect.sdks.find_qt"] = { },
    __version = "2.3.6",
    find_program = {
        qmake = [[C:\Qt\Qt5.14.2\5.14.2\mingw73_64\bin\qmake]]
    }
}

默认生成的xmake.lua

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

target("test")
    add_rules("qt.widgetapp")
    add_headerfiles("src/*.h")
    add_files("src/*.cpp")
    add_files("src/mainwindow.ui")
    -- add files with Q_OBJECT meta (only for qt.moc)
    add_files("src/mainwindow.h")

希望知道的能帮忙解答一下，万分感谢！

我在test分支上加了点调试信息，你安装下这里面的包 https://github.com/xmake-io/xmake/actions/runs/233688773

然后同样的执行，再给我一份完整的输出信息

您好，可能因为网络问题，我这里下载多次都显示压缩包损坏，如果可以的话能发到我邮箱里么？pchuan98@qq.com

我的和这个情况一样，用test分支打印信息如下

大概知道了 QT_INSTALL_ARCHDATA:C:/Qt/Qt5.14.2/5.14.2/msvc2017_64

在 win 上取得环境值，按 : 分隔 key/value ，被 C: 里面的 冒号干扰了，我一会改下。

waruqi commented 4 years ago

我改好了，可以直接执行 xmake update -s dev 更新下脚本，或者直接到 https://github.com/xmake-io/xmake/actions/runs/233884380 上下载安装包 重装下 （目前还在 build 中。）

pchuan98 commented 4 years ago

xmake update -s dev

已解决，谢谢了。

这个安装包运行之后出现如下问题：

我不知道你配置的平台和运行环境，自己看下 下面哪个条件没满足

        if is_plat("windows") or (is_plat("mingw") and is_host("windows")) then
            target:add("runenvs", "PATH", qt.bindir)
            target:set("runenv", "QML2_IMPORT_PATH", qt.qmldir)
            target:set("runenv", "QML_IMPORT_TRACE", "1")
        elseif is_plat("msys", "cygwin") then
            raise("please run `xmake f -p mingw --mingw=/mingw64` to support Qt/Mingw64 on Msys!")
        end

请问VSCode插件也是您负责的么？在使用xmake创建project的时候我遇到了这个问题

> Executing task: xmake create -t qt.widgetapp -l c++ -P c:\temp\demo <

create demo ...
error: project directory (C:\temp\demo) is not empty!
The terminal process "C:\Windows\System32\cmd.exe /d /c xmake create -t qt.widgetapp -l c++ -P c:\temp\demo" failed to launch (exit code: 4294967295).

Terminal will be reused by tasks, press any key to close it.

提示的是这个文件夹不是空的，但是我的这个文件夹里面是没有东西的。

waruqi commented 4 years ago 
xmake create -t qt.widgetapp -l c++ -P

确认下是否真的为空，是否存在隐藏文件，或者通过 xmake l os.emptydir "c:\temp\demo" 判断下

    if not os.emptydir(projectdir) then
        -- otherwise, check whether it is empty
        raise("project directory (${underline}%s${reset}) is not empty!", projectdir)
    end

另外，不同的问题，请另开issues
