compilation

I am coding in Eclipse and have something like the following: #include <ftream> #include <iostream> void read_file(){ char buffer[1025]; std::istringstream iss(buffer); } However, when I try to build, I get the following error: variable 'std::istringstream iss' has initializer but incomplete type Any quick thoughts? I have googled around and it seems like most people with this problem simply did not include the right header files which I believe I am doing correctly. Jive Dadson You need this include: #include <sstream> 来源： https://stackoverflow.com/questions/13428164/c-compile-error-has

This question already has an answer here : What IDE to use for Python? [closed] (1 answer) Possible Duplicate: What IDE to use for Python I have Notepad++ and NetBeans 6.8, however I don't know if they work. I know you can edit Python with Notepad++ and compile/run it using the command line thing, but I'm not really sure how. I know NetBeans is a full-featured IDE and you can compile Java programs, but I don't think they support Python? Any ideas? Eclipse with PyDev has been a great combination for me. Great editing experience and more importantly a good debugger. Pylint is supported as well,

I am looking for any tutorials or information on compiling Qt 4.7 with Visual Studio 2010. I've recently have run into an bug using Qt 4.7.1 libraries on Visual Studio 2010 and have found information that recompiling Qt with 2010 can potentially solve it. Edit : This has solved the issue. Ref: http://www.qtforum.org/article/34406/heap-corruption-caused-by-calling-selectedindexes-method-of-qitemselectionmodel-class.html After Researching for awhile, I was successfully able to compile Qt in VS2010 using the following: Compile: set QMAKESPEC=win32-msvc2010 configure -platform win32-msvc2010 nmake

I'm wondering about the purpose, or perhaps more correctly, the tasks of the "reader" during interpretation/compilation of Lisp programs. From the pre-question-research I've just done, it seems to me that a reader (particular to Clojure in this case) can be thought of as a "syntactic preprocessor". It's main duties are the expansion of reader macros and primitive forms. So, two examples: 'cheese --> (quote cheese) {"a" 1 "b" 2} --> (array-map "a" 1 "b" 2) So the reader takes in the text of a program (consisting of S-Expressions) and then builds and returns an in-memory data-structure that can

I am able to compile scala programs using scalac in terminal but I get the warning. Charless-Macintosh:src Charles$ scalac hello.scala Charless-Macintosh:src Charles$ scala HelloWorld No such file or class on classpath: HelloWorld Is this to do with .profile on scala. I'm pretty confused as to what is happening. Many thanks The current directory is typically not in the classpath by default. So you need to give explicitly: $ scala -cp . HelloWorld The problem is that you have set the CLASSPATH environment variable. From > man scalac : The default class path is the current directory. Setting the

I'm making a falling sand game in Java. I want users to be able to write their own engine for it using a simpler language. Falling sand games can be very CPU intensive so I want to have the engine running as fast as possible while not having to manually compile. I need to know how to compile rhino javascript files to .class files by at runtime to be used. I've looked for a way but couldn't find any other than manually compiling it by using the command line which I don't want users to have to do. There's a short tutorial here: Scripting: Compiling Scripts in Java jbeard4 My solution here: Has

I'm developing a C++ project which is going to be enclosed on a bigger one. I've seen that on the bigger project (is a Qt application and it's being generated from qmake) I am able to compile a single file from the linux command line, just entering the relative path to the specific file as an argument to make. On the other hand, I'm using CMake for my own project. When I modify some code for a compilation unit and I have to modify its header file, I have to wait a long time to compile its dependencies and then its own source file. But there are some situations in which I would prefer to check
