C/C++编译问题，静态库，动态库。

现在在一个文件夹下面有动态库libtest.so, libalex.so, 有一个静态库libtest.a,我想编译main.c链接动态库libalex.so和静态库libalex.a，怎么做？ 试过，不行的有： 1. g++ main.c -L./ -lalex -static -ltest (这样static是作用全局的，全用静态库) 2. g++ main.c -L./ -lalex -L./libtest.a (不行，找不到./libtest.a) 3. g++ main.c -L./ -Bdynamic -lalex -Bstatic -ltest (不行，全用动态库) 手误，我是想编译main.c链接动态库libalex.so和静态库libtest.a，请教！

g++ main.c -L. libalex.so -ltest

的dll一起拷贝到别人电脑上去！ 还有一些特别的情况，虽然是针对VC2005的，但是对VC6也有参考价值。 前面一些是我在网上找的，后面的有些是我自己现添加的，希望对你有帮助！ 报错"由于应用程序配置不正确,应用程序未能启动.重新安装应用程序可能会纠正这个问题" //------------------------------------------------------ 这个问题主要出现在XP环境下运行由Visual C++2003/2005编译的MFC程序时 问题现象是XP运行此类程序时,报错"由于应用程序配置不正确,应用程序未能启动.重新安装应用程序可能会纠正这个问题" 这个问题似乎许多人遇见过.在CSDN和微软社区里面都有人提到.但是没有完整的解决方案 这个问题的解决一共会遇见2个子问题 最早出现这个错误我和许多人认为的一样 认为是缺乏DLL库文件导致.但是在测试机复制了DLL甚至安装了.net framework 2.0以后 都无法解决问题,最后确认不是由缺乏DLL所致 因为程序是纯win32的应用程,非托管代码,所以也无需.net framework Visual C++2003/2005默认的MFC程序是使用动态MFC库(Use MFC in a Shared DLL)来链接的 而动态MFC库使用的是Multi-threaded DLL (/MD) 由于XP对于PE文件格式监测更加严格. 就会导致部分使用多线程DLL的可执行文件在调用的时候出错 修改项目属性的编译开关 Project->Property->configuration Properties->C/C++->Code Generation->Runtime Library 修改成Multi-threaded (/MT) 修改了Runtime类型以后 需要将MFC的编译类型也改成静态库 Project->Property->configuration Properties->General->Use of MFC 修改成Use MFC in a Static Library 一部分情况下在这步就能解决问题 另外一部分情况会遇见如下情况 编译器报错 CODE: nafxcw.lib(afxmem.obj) : error LNK2005: "void * __cdecl operator new[](unsigned int)" (??_U@YAPAXI@Z) already defined in libcpmt.lib(newaop.obj) [Copy to clipboard] 产生这个问题的原因是库依赖关系 在Project->Property->configuration Properties->Linker->Command Line 加入编译开关/verbose:lib可以显示详细的库链接顺序 CODE: ------ Build started: Project: PerfMonDemo, Configuration: Release Win32 ------ Linking...

new在nafxcw.lib中再次定义 解决方法如下 Project->Property->configuration Properties->Linker->Input->Additional Dependencies 加入 nafxcw.lib libcpmt.lib Project->Property->configuration Properties->Linker->Input->Ignore Specific Library 加入 nafxcw.lib libcpmt.lib 这样链接程序就不会先按照默认顺序来连接这两个库文件 而是在最后在加入对他们的引用.这样就避免了这个问题 下面是一张可能发生冲突的列表 若要使用此运行时库 请忽略这些库 单线程 (libc.lib)

另外,站长团上有产品团购,便宜有保证
