lib调用 奇葩的事情

[xia56108430]

请教大家个问题！有没有人遇到过，希望指教下！

在程序中调用一个a.lib，而a.lib调用b.lib！

现在的情况是

如果一个完整的a。lib库（不调用b。lib），在依赖项中，放着b.lib，程序运行不起来！，就是外围程序都运行部起来！

此时，b。lib根本就没调用，连a。lib也没调用！

[beyondma]

是不是签名的事情，让你的A加载不进来啊？

[北方大冬瓜]

lib 是静态编译用的吧？应该不必设置依赖，加入到工程里就可以吧

没遇到过，还是设置问题吧～～～

奇怪的问题，LZ可以看看TCPMP的例子。是动态的嵌套调用。

谢谢，我仔细看看！

目标都是ARM！

然后我用dumpbin看了下lib里面的信息
是这些！

说实在，不明白什么意思？
看了下，其他的lib好像跟这个有点区别！
正常的，没有ordinary name这项，Summary很多！

求牛人指教下！

签名？什么意思？

[biosli]

这个问题很具体没法帮你分析只能告诉你点注意事项。
1、在a.lib中只能包含b.lib的头文件引用不能包含b中的函数实现，因为静态链接库是把用到的函数包起来的，所以假如a.lib和b.lib中同时有一个函数实现会在连接期报错。
2、a.lib和b.lib的工程目标选项应该一致，比如你编译了b.lib用的是Debug|Windows Pocket PC 5.0，你的a.lib也应该是在Debug|Windows Pocket PC 5.0下编译的。
3、静态链接库a.lib和b.lib是分别编译的，你应该还有一个exe工程，这个工程应该同时引用a.lib和b.lib，因为你调用a.lib中函数的同时有可能需要用到b.lib的内容。


另外，我想知道楼主所说的“运行不起来”指的是什么。运行提示如果是红叹号“无法运行”，基本可以断定是我上面说的错误2.

[sxcnfly]

a与b库你说没有被调用，应该是根本就不会被链接进去，如果链接进去了就说明还是被调用了，出现这种情况还是库与宿主程序的编译选项不一致导致的。
