linker and loader

Content summary If you have used WPF and Silverlight for development, you will surely have this experience. We often want them to share it with each other.CodeBecause, after all, it is very similar. However, because the runtime is different, Silverlight cannot reuse WPF by default.ProgramSet. Previously we could do this by manually adding links. I have a blog here to illustrate this practice (http://www.cnblogs.com/chenxizhang/archive/2010/10/09/1846781.html ), this article explains how to use

LINK (LD): GCC will go to the system's default search path "/usr/lib" to find, that is, linked to the Libc.so.6 library function . function library is generally divided into static library and dynamic library two kinds . Static library refers to the compilation of links, the library files of the code are all added to the executable file, so th

AL.exe use a program to generate an EXE file or DLL PE file (which contains only a list of the types that are described in other modules).Do not compile in a normal command-line window, first open C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Microsoft Visual Studio 2010\visual Studio Tools path, under Visual Studio command Prompt (2010), enter the command in this window.To give a simple exampleCsc/t:module RUT.csCsc/t:module FUT.csAl/out:jefftypes.dll/t:library Fut.netmodule Rut.netmodul

Basic Linker Script Concepts Every loadable or allocatable output section has two addresses. The first isVMA, Or virtual memory address. This is the address the section will have when the output file is run. The second isLMA, Or load memory address. This is the address at which the section will be loaded. You can see the sections in an object file by usingobjdumpProgram with the-h option.For exampleObjdump XX.exe-h Stage1.exec.exe: file format pei-i3

This problem usually occurs when you add a third-party library file or when you develop multiple people.This problem is usually a link error that is caused by a file not being found. We can proceed from the following aspects of the investigation.1. Take the following error as an example, if you are a multi-person developer, you will find the following error when you complete the synchronization.[HTML]View Plaincopy Undefined Symbols for Architecture armv7: "_objc_class_$_mypagelogvi

General executableProgramBoth includeCodeSegment and data segment. It can also be viewed as composed of the RO and RW segments. The RO section generally contains code segments and constants, which are read-only during running. The RW segment includes some global and static variables that can be changed during running (read/write ). If some global variables are initialized to zero, the RW segment also contains the Zi segment.RO: Read Only code segmentRW: Read Write the initialized global variable
