问题 how can I change Qt install path after I building it ? Example : qmake.exe search binaries to original install path, how can I change/redefine it ? Thanks. Edit : I finally found this patch to apply to Qt : http://ftp-developpez.com/qt/binaires/win32/patcher/QtPatcher.7z http://ftp-developpez.com/qt/binaires/win32/patcher/QtPatche_src.7z 回答1: I was looking into this and found a way that works (in qt 4.7.2) by customizing qt with a qt.conf file. In my case, I added a qt4-4.7.2/bin/qt.conf (I

问题 The --sysroot switch is useful when you don't want the headers/libraries in the standard paths affect your build. --sysroot=dir : Use dir as the logical root directory for headers and libraries. For example, if the compiler would normally search for headers in /usr/include and libraries in /usr/lib, it will instead search dir/usr/include and dir/usr/lib. [ref] Can the same thing be accomplished through the use of environment variables, the gcc specs file, or any other methods that do not

问题 Original Question This seems easy and has likely been asked before, but I could not find it via a search. I have a few flavors of R installed. I simply want to know, when I run RStudio, which flavor of R is it pointing to. So, I need a command -- within RStudio itself, ideally -- that can tell me the underlying R executable that is being used for this RStudio window that I am currently working with. To be clear, I do not need / want to know the version of R that I'm using (e.g., R version 3.2

问题 I am working on a media player in C# but when I want to make my test I have a problem. I have to create a new object song with the following path: @"C:\Users\Jesus Antonio\Desktop\JukeboxV2.0\JukeboxV2.0\Datos\ich will.mp3" It works but when I change the computer I have to rewrite the entire path, My project is called JukeboxV2.0 In java I remember you can just write the path for example @"JukeboxV2.0\JukeboxV2.0\Datos\ich will.mp3" This will save a lot of time because I can take my project

问题 Java 7 introduced java.nio.file.Path as a possible replacement for java.io.File. With File, when I access a file under a specific, I would do: File parent = new File("c:\\tmp"); File child = new File(parent, "child"); // this accesses c:\tmp\child What's the way to do this with Path? I supposed this will work: Path parent = Paths.get("c:\\tmp"); Path child = Paths.get(parent.toString(), "child"); But calling parent.toString() seems ugly. Is there a better way? 回答1: Use the resolve method on

问题 Im looking for an algorithm to be used in a racing game Im making. The map/level/track is randomly generated so I need to find two locations, start and goal, that makes use of the most of the map. The algorithm is to work inside a two dimensional space From each point, one can only traverse to the next point in four directions; up, down, left, right Points can only be either blocked or nonblocked, only nonblocked points can be traversed Regarding the calculation of distance, it should not be

问题 I am working on some Eclipse projects that are stored on a USB key. I have added them to a workspace whose root folder is also on the USB key, but the projects are not located directly into this directory. As a result their absolute paths are written in the .projects folder of the workspace. This raises problems when I use the key on several computers, because the drive letter assigned to the USB key is not always the same (and I do not want to assign a specific letter to it on all computers)

问题 I'm writing a template for dreamweaver, and don't want to change the scripts for subfolder pages. Is there a way to make the path relative to the root directory? for example: <link type="text/css" rel="stylesheet" href="**root**/style.css" /> Instead of **root** above, I want a default path there. Is there any way to do anything like this? 回答1: To be relative to the root directory, just start the URI with a / <link type="text/css" rel="stylesheet" href="/style.css" /> <script src="/script.js"

问题 Is there anything built into System.IO.Path that gives me just the filepath? For example, if I have a string @"c:\webserver\public\myCompany\configs\promo.xml", is there any BCL method that will give me "c:\webserver\public\myCompany\configs\"? 回答1: Path.GetDirectoryName() ... but you need to know that the path you are passing to it does contain a file name; it simply removes the final bit from the path, whether it is a file name or directory name (it actually has no idea which). You could

问题 This question already has answers here : Is there a way to get the git root directory in one command? (22 answers) Closed 2 years ago . I'm looking for something like git list-path printing the path of the associated repository (the .git directory). A bit of background: I have set up git version control on quite a few of my projects/folders. Some of them are nested, so one directory with echo own repository is a subfolder to another directory tracked with another repository. E.g. in my home
