compilation

问题 Closed . This question is opinion-based. It is not currently accepting answers. Want to improve this question? Update the question so it can be answered with facts and citations by editing this post. Closed 5 years ago . I have this big C++ boostified project that takes ages to build so i'm trying to set up compilation firewalls. Now I could sprinkle pimpls or pure interfaces following my intuition but that doesn't seem very efficient... usually if i wanted to optimize a piece of code, I

问题 What is the difference between including a file from a header file or from a source file in C++ in regards to performance during compilation? What are the reasons to include files in the source file and not in the header file (except when absolutely required)? Does the one (header) affect compile time and the other (source file) affect link time? 回答1: When you include a file in either place, you can think of it as being expanded in the file, which then has to be processed by the preprocessor

问题 I installed Python and MinGW, added everything which is needed to PATH (g++ and python), and downloaded omniORB from http://sourceforge.net/projects/omniorb/files/omniORB/omniORB-4.1.6/omniORB-4.1.6.tar.bz2/download, unzipped it. I cded to omniORB directory but there were no omniORB binaries in \bin\x86_win32 directory. So I have 2 questions: 1) where can I get omniORB binaries? (I would like to install omniORB on my computer with Windows XP/Vista (both x86)) 2) is it possible to install

问题 Suppose I have some code that would, in theory, compile against any version of the .net framework. Think "Hello World", if you like. If I actually compile the code, though, I'll get an executable that runs against one particular version. Is there any way to arrange things so that the compiled exe will just run against whatever version it finds? I strongly suspect that the answer is no, but I'd be happy to be proven wrong... Edit: Well, I'll go to the foot of our stairs. I had no idea that

问题 As it currently stands, this question is not a good fit for our Q&A format.

问题 In Xcode 3.0, you can use Project Targets in Groups & Files panel to remove unwanted dependency files. Below is the instruction. Click the arrow next to Targets until you expand it in the Groups & Files panel. Click the arrow next to xauth. Click Compile Sources. Delete the following YAJL dependency files. How do you do it in Xcode 4.0? 回答1: It's very similar: Select the project in the project navigator. Select the Target in the detail view. Select the Build Phase tab. Expand the Compiled

问题 I have a C# application of which some parts are written using WPF (which is not supported by Mono). Is it possible to compile this application on Linux? Ultimately, the application will run on Windows, but it is part of a larger framework and our entire build process runs on Linux, so I would like to be able to compile the C# application on Linux as well. 回答1: Mono does not, and currently has no plans to support WPF, and by proxy, XAML. Where you might get a break with a subset of XAML is

问题 Scenario: I have VS 2010 (C# 4 compiler) targeting 3.5 on my client machine. I am developing ASP.NET applications. I use optional parameters (C# 4 supported) in a class file and compile the code everything appears to work fine. Later on an issue that is discovered at Runtime where an old (classic I believe) ASPX is using the function. No function accepts only x arguments where x is one less than the optional parameter is the runtime error. Does this mean normal classes and such use the C#

问题 I'm trying to add OCMock to my existing Cocoa project, but am running to a strange problem that I don't see anyone else cover. I finally isolated it to the following: if I simply add OCMock.framework reference to my project (i.e. drag it in somehow into Link Binary With Libraries build phase), when I run tests, the real app gets launched instead. Without OCMock, the output is normal: Test Suite 'Multiple Selected Tests' started at 2013-02-07 20:07:03 +0000 With OCMock framework link (partial
