0. Write in frontFor the first contact with the Linux system, the installation of ns-3 seems unfriendly. But in fact, the installation process is not as complex as it seems to be. In this article, the installation process in the official Wiki is slightly combed, hoping to bring some convenience to those who have just started learning.At the same time, the descriptive narrative in the official Wiki is sufficiently specific. Therefore, there will be a large section of references in this article an
to compile manually.Users under Linux are less fortunate. Although there is also a page https://github.com/goldendict/goldendict/wiki/Early-Access-Builds-for-Linux-Portable, but has not been maintained for more than two years. The Ubuntu software warehouse is not much better, the above package has been discontinued since 2013, and there is currently no active PPA maintainer.So under Linux, if you experience the latest goldendict, manual compilation i
C + + template class Understanding compiler's compile template processI've often encountered questions about whether it's easy to use a template, and my answer is: "The template is easy to use, but the organization is not easy to write." Look at the types of templates that we can meet almost every day, such as STL, ATL, WTL, and Boost's template classes, all of which can be tasted: the interface is simple, the operation is complex.
I started using th
There are two methods of compiling a CHM project (. hhp):
Call Hhc.exe
Call HHA_COMPILEHHP
Call Hhc.exe compile with the following code:
// strChmFileName为你的hhp文件的长文件名 CString strCmdLine; strCmdLine = "hhc.exe "; strCmdLine += strChmFileName; WinExec(strCmdLine, SW_SHOWNORMAL);
There are many drawbacks to invoking this method, first, there is no compilation progress, no prompts, and according to my tests, there is no support for the file names wi
GCC (GNU Compiler Collection) is the most commonly used C language compiler under Linux and is a compiled system conforming to the ANSI C standard in the GNU project, capable of compiling programs written in C, C + +, and object C.There are two common ways to use Linux systems, as follows:Gcc-o out in1 in2 //gcc Compile and link (compile and build in2 file for in1 and Out.b
Constants are constant amounts of time during a program's run, and many programming languages have some way of telling the compiler that a piece of data is constant, such as const in C + + and final in Java.
According to the different behavior of the compiler, the constants are divided into compile constant and run -time, in fact, the compiler is always the usual amount of work, just compile the consta

There are many reasons why database objects fail due to database object invalidation, and some common reasons are summarized below:
1: When the structure of the referenced object changes, the dependent object is changed to the invalid state.
The objects in the database (stored procedures, functions, packages, views, triggers, which often need to refer directly or indirectly to other objects, the object's dependencies inc

GNU Compiler setThe GNU Compiler set (formerly the GNU C compiler) was born in 1987. At that time, Richard Stallman (founder of the GNU Project) wanted to create a compiler that would meet his defined "free software" concept and be used to compile other software published by the GNU Project. The GNU C compiler is quickly popular in the free software community and is known for its robustness and portability.
In general, we'd better compile this platform's binaries on one platform, such as compiling 32-bit programs on 32-bit platforms and compiling 64-bit programs on 64-bit platforms.
Now 64-bit systems (mostly x86_64 systems, including AMD64 and Intel's EM64T) have been widely used, even if you now want to buy 32-bit processors. The 64-bit system also has a significant improvement in performance and processing capabilities relative to the 32-bit syste
