我被卡住了,为什么我不能使用LoadLibrary加载我的动态链接库“接口”。它在加载依赖项时似乎失败了,但我不确定原因。
代码如下:
AfxMessageBox(L"before load library");
HMODULE interfacDll = LoadLibrary(TEXT("C:\\QA\\Pcdlrn\\Win32\\Release\\INTERFAC.DLL"));
if (!interfacDll)
DWORD dw = GetLastError(); // returns 0xc1 (193)
AfxMessageBox(L"after load library");下面是gflags (X86)的加载程序快照的输出:

编辑:虽然下面的是有意义的,但实际上是不正确的。我把它留在这里只是作为参考,但我可能稍后会删除答案。
但是请注意(至少在Windows10上,我经常检查)即使重定位信息在文件中可用,如果模块不是动态链接库,它也不会被应用,所以即使你没有得到那个错误,除非你的INTERFAC.DLL在加载它后对PCLDRN.exe应用重定位,否则尝试使用它很可能会在过程中的某个地方中断。
有了加载器快照的输出,这种情况对我来说似乎很明显。
一旦找到文件,加载器就会抓拍输出(我对行进行了编号):

但是导致加载失败的错误是0x40000003 - STATUS_IMAGE_NOT_AT_BASE。此NTSTATUS的描述为:
{图像已重定位}无法在图像文件中指定的地址映射图像文件。必须对此映像执行本地修复。
(来源:NTSTATUS Values)
默认情况下,EXEs不包含重定位信息(如注释中所述)。通常这不是问题,因为当EXE加载到地址空间中时,地址空间是相当空闲的。但是您的地址空间不是空闲的。更糟糕的是,默认情况下,由Visual C++编译的所有EXEs都共享相同的基地址:
/BASE选项设置程序的基地址,覆盖.exe或DLL文件的默认位置。对于32位图像,.exe文件的默认基地址为0x400000;对于64位图像,默认基地址为0x140000000。对于DLL,32位映像的默认基址为0x10000000,64位映像的默认基址为0x180000000。
(来源:Linker Options: /BASE (Base Address))
这可能就是你遇到的情况。CNCServer.exe已经占用了0x400000,这是PCDLRN.exe唯一可以使用的地方。LdrpMapViewOfSection无法将PCDLRN.exe映射到0x400000,因为它不是免费的,并且由于没有重新定位信息而无法映射到其他任何地方。
从那里,它向上调用堆栈,并更改错误,但不是潜在的问题。这就是缺乏重定位信息。
您也可以看到在输出中包含重定位信息的DLL遇到此错误时发生了什么。最初加载INTERFAC.dll时:
