log4cxx错误消息 [英] log4cxx error massage

问题描述

我正在使用VS2005和log4cxx 10.0.1记录日志.
我下载并构建了log4cxx.
然后将.dll和.lib文件复制到正在运行的(新)项目中.
还制作了.xml文件.
以及所有必要的更改以构建新项目.

我成功建立了新项目，但是当我运行该项目(新)时，弹出一个错误消息框，提示

过程入口点?getLogger @ Logger @ log4cxx @@ SA?AV?$ ObjectPtrT @ VLogger @ log4cxx @@@ halpers @ 2 @ QB_W @ Z不能位于动态链接库log4cxx.dll中."

Also made the .xml file.
and all required changes to build new project.

I built new project successfully but when i run the project(new), an error msg box is poping up saying

"The procedure entry point ?getLogger@Logger@log4cxx@@SA?AV?$ObjectPtrT@VLogger@log4cxx@@@halpers@2@QB_W@Z could not be located in the dynamic link librarylog4cxx.dll"

is there any one to help me out for this...i stuck in this...Any help will be realy appriciated..Thanks in advance...

一些想法:构建应用程序时使用__declspec(dllimport)，而构建DLL时使用__declspec(dllexport)?我相信如果其中一个或另一个不存在，那么它们将使C ++名称混乱，如果为true，则将导致它在运行时无法在DLL中找到该函数.

(这些东西对我来说一直有点像魔术饼干，我从未尝试过.)

另外，如果从C ++调用DLL的.h文件，可能需要用extern "C" {包裹起来，这似乎是这种情况.尽管我原本希望log4cxx标头已经包含此标头:

A couple of ideas: was __declspec(dllimport) used when building the app and __declspec(dllexport) when building the DLL? I believe those will mess with the C++ name mangling if one or the other is not present, which if true would cause it not to find the function in the DLL at run-time.

(Those have always been a bit like magic cookies to me, I''ve never experimented with them.)

Alternatively, the .h file for the DLL may need extern "C" { wrapped around it if being called from C++ which appears to be the case. Although I would have expected the log4cxx header to include this already:

#ifdef __cplusplus
extern "C" {
#endif

[function definitions]

#ifdef __cplusplus
}
#endif
