Entry Point Not Found的问题

clever101 2008-09-03 05:34:03

编译一个程序，debug版本可以顺利启动，release版本出现一个错误：
*.exe 中的 0x7c984ed1 处最可能的异常: 0xC0000139: Entry Point Not Found

试着调试，发现这个调试不了，app类的构造函数都没有进入。上网也没有搜到更好的资料。

编译环境：VS C++ 2005, Win XP sp2。

我看有两个地方要查：
1、编译选项，对比Debug和Release，是否选择了不同的函数作为入口点
2、检查main（假设这就是你的入口点函数的话）前后是否使用的#ifdef之类的宏限定

具体怎么查呢？

像是某个隐式链接的dll与lib的版本不对。

Installing c++/g++ on Windows Disclaimer: This page is being maintained mainly for my students. Use these instructions at your own risk. There is no warranty in any form or shape whatsoever!. There is no guarantee that these instructions are up-to-date. With that understood you may continue with the rest of this page if you choose to accept these terms. This page was last updated on September 13, 2005, but still good as of April 30, 2009. Follow these steps to install g++ (the GNU C++ compiler) for Windows. There is no room for creativity here; you must follow the directions exactly. Pick the drive and a folder in which you want to install g++. I'll assume that it is C:, but you can choose a different one. If you choose a different drive or a different folder, you'll need to adapt the directions below accordingly. Download full.exe, an about 14 megabyte executable, to C:\full.exe by right-clicking on the link. Use Save Link As... or Save Target As... Be sure the browser saves the file as C:\full.exe. Run the downloaded executable. This will install g++ (and a lot of other things that you don't really need) on your hard drive. Go to the C: drive using Windows Explorer and double-click on full.exe. Or, open a DOS window (Start > Programs > Command Prompt), connect to the C: drive using the cd command, and type full. Locate where the bin folder was created for the g++ installation. On my Windows XP machine, it was created in the following path: C:\cygnus\cygwin-b20\H-i586-cygwin32\bin You now should add it to the PATH environment variable. You do that by following: Start -> Control Panel -> System -> Advanced -> Environment Variables At this point you can see the PATH variable either in the User Variables or in the System Variables. Add the g++ path into the PATH variable. You add it to the end of the existing value separated by a semicolon (';'). Make sure that you do not lose the original value. You are just appending more to the end separated by a semicolon. Restart your computer. A Cygnus Solutions entry will appear in your Programs menu, and an icon may appear on your desktop. Don't use them! You will use it using the g++ command on a DOS prompt as explained below. You should now be able to run g++ from a DOS (Command Prompt) window. For example, to compile a file called C:\mine\hello.cpp, connect to the C:\mine folder and enter g++ -g hello.cpp -o hello -lm You'll then be able to run the compiled program by entering hello in the DOS window. If you've installed Emacs as described here, you will also be able to run g++ from Emacs. If, when you do this, Emacs tries to compile with the command make -k, you made a mistake during the Emacs installation. If you want to learn how to run g++ on emacs, see here. If you'd like to learn more about where this free compiler came from, we downloaded it from an older site of http://sourceware.org/cygwin/. If you wish to clean up a little, you may delete the file: full.exe at this point. Your g++ compiler is installed under C:\cygnus.

使用LoadLibrary 时，加载失败，调试器弹框中断，报错：Entry Point Not Found；拿dll的代码跟调，发现连dllmain都没进，用老版本的dll可以加载上，新版本就不行，然后各种百度，有人说是像是某个隐式链接的dll与lib的版本不对。但是我的lib都是重新生成的，还不行。最后没办法了，各种瞎找资料，在看一个英文网站上偶然有了点思路：https://ofe...

问题描述在使用封装好的vs .exe文件的时候，编译没问题，最后会跳出无法定位程序输入点xxx于动态链接库xxx.dll的问题。在网上冲浪好久，各种方法都试过了，更新dll文件也不行。解决方案调试结束后会出现：ntdll.dll0x00007FFE41CB23F6 (ntdll.dll)处(位于 *** 中)引发的异常: 0xC0000139: Entry Point Not Found。所以从 Entry Point Not Found 这个问题着手，偶然看到说是 Windows 文件已损坏或丢

本文告诉大家如果在使用 release 编译时，无法启动应用，出现 Entry Point Not Found 如何让应用运行

"Entry point was not found." 意味着程序找不到入口点，可能是因为缺少必要的文件或组件。解决方法可能包括：确认安装了所有必要的运行库和组件。检查程序文件是否损坏或缺失。重新安装程序。检查是否有其他程序正在占用所需的文件或端口。确认程序的兼容性问题，比如操作系统版本问题。如果仍然无法解决问题，建议查找程序相关论坛或技术支持，以获取更详细的解决方案。 ...

VC/MFC社区版块或许是CSDN最“古老”的版块了，记忆之中，与CSDN的年龄几乎差不多。随着时间的推移，MFC技术渐渐的偏离了开发主流，若干年之后的今天，当我们面对着微软的这个经典之笔，内心充满着敬意，那些曾经的记忆，可以说代表着二十年前曾经的辉煌……
向经典致敬，或许是老一代程序员内心里面难以释怀的感受。互联网大行其道的今天，我们期待着MFC技术能够恢复其曾经的辉煌，或许这个期待会永远成为一种“梦想”，或许一切皆有可能……
我们希望这个版块可以很好的适配Web时代，期待更好的互联网技术能够使得MFC技术框架得以重现活力，……
