compilation

问题 Problem I'm trying to install Python 3 with the --enable-shared option. Installation "succeeds" but the resulting Python is not runnable. Trying to run Python after installation gives the following error: $ /opt/python3/bin/python3.5 /opt/python3/bin/python3.5: error while loading shared libraries: libpython3.5m.so.1.0: cannot open shared object file: No such file or directory Background The OS is Debian (squeeze), and has a previous installation of Python 2.6, which is necessary to retain

问题 Is there a way to disable the real time compilation in Visual Studio 2015? It's grinding to a halt whenever I make changes that have a ripple effect throughout my dependent code. The error list updates even before saving the C# file I'm working on, filling it with CS**** compiler errors as I'm typing. 回答1: In visual Studio 2015 go to tools , options , text editor , C# , Advanced and uncheck Enable full solution analysis . This should stop your problem as the solution won't be checked every

问题 Is there a way to force an inline function in Clang/LLVM? AFAIK, the following is just a hint to the compiler but it can ignore the request. __attribute__((always_inline)) I don’t mind that the compilation will fail if it can’t inline the function. 回答1: There is a good solution if compiling with C99 which is Clang's default. Its simply using inline attribute. inline void foo() {} It is well written in Clang's compatibility page: By default, Clang builds C code according to the C99 standard,

问题 Does anyone know which target/libs are required for Node.js v10.x to use the built in async/await without the generators? I see a lot for node 8 but not with node 10. 回答1: As of Node.js 10.0.0 , 100% of ES2018 is supported. If you know that you are targeting that version or newer, the optimal config would look like this: "module": "commonjs" Node.js is on it's way to add ES-Modules, but for now we'll have to stick with CommonJS. "target": "es2018" This tells TypeScript that it's okay to

问题 Does linking and loading of the the dynamic libraries both happen at runtime? or is it that only loading of the library happens at run time? 回答1: See the earlier very good point about the distinction between static linking and dynamic linking. Assuming you are referring to the dynamic linking, then: Both loading and (dynamic) linking are done by the linker – on linux and other Unix-alikes this is done by /lib/ld.so , which is the actual program that is launched by the operating system in

问题 I wonder if it is possible to create an executable module from a Python script. I need to have the most performance and the flexibility of Python script, without needing to run in the Python environment. I would use this code to load on demand user modules to customize my application. 回答1: There's pyrex that compiles python like source to python extension modules rpython which allows you to compile python with some restrictions to various backends like C, LLVM, .Net etc. There's also shed

问题 Let's say I have a project that uses a dependency that can be found in the Maven repository. However, lets also say that the jar file that will be downloaded is NOT in a format that is suitable for my project (e.g. if my maven project is an Android project and the jar has been compiled in a way the dex tool does not like). What I want to do instead is to downloaded the source version of that dependency. Once I add java-source, however, the classes are not accessible anymore from my own source

问题 I understand that Web Site Projects compile source on-the-fly, and Web Application Projects pre-compile source into a DLL (much like ASP.Net 1.x). But how is the difference specified in IIS? I know that Visual Studio knows -- there are different projects for each, etc. But the running instance (IIS + Framework) has to know which compilation model is being used, right? Because how else does it know whether or not to compile on-the-fly? A request comes in, hits an ASPX file...and how does the

问题 I currently have the following routines in my Global.asax.cs file: public static void RegisterRoutes(RouteCollection routes) { routes.IgnoreRoute("{resource}.axd/{*pathInfo}"); routes.MapRoute( "Default", "{controller}/{action}/{id}", new { controller = "Arrangement", action = "Index", id = "" } ); } protected void Application_Start() { RegisterRoutes(RouteTable.Routes); // Debugs the routes with Phil Haacks routing debugger (link below) RouteDebug.RouteDebugger.RewriteRoutesForTesting
