LoadLibrary失败,找不到模块错误 - 可能存在依赖性问题(LoadLibrary is failing with module not found error — possible dependency problems)

我一直在尝试使用C ++(来自32位应用程序,在Windows 7 64位上)加载32位dll。 LoadLibrary返回NULL,并且GetLastError返回126“无法找到指定的模块”。

我将完整的地址传递给LoadLibrary函数。 我在Dependency Walker中打开了dll,它说GPSVC.dll是一个缺失的依赖。

从谷歌搜索我已经完成,看起来像Dependency Walker经常错误地将此GPSVC.dll显示为缺少依赖,并且没有32位版本,所以我不认为那是实际问题。

过去我没有做太多关于dll的讨论,所以希望这是一个相对简单的问题我可以借鉴。

在此先感谢您的帮助!


I have been trying to load a 32-bit dll using C++ (from a 32-bit application, on windows 7 64-bit). LoadLibrary returns NULL, and GetLastError returns 126 for "The specified module could not be found."

I am passing in the complete address to the LoadLibrary function. I opened the dll in Dependency Walker, which said GPSVC.dll was a missing dependency.

From the googling I've done, it looks like Dependency Walker often falsely shows this GPSVC.dll as a missing dependency, and there is no 32-bit version of the it, so I don't think that that's the actual problem.

I haven't done too much finagling with dlls in the past, so hopefully it's a relatively simple problem that I can learn from.

Thanks in advance for any help!

fn:last()的文档示例显示了此函数的非常相似的用法。 在谓词中使用函数的缺点是,它们是针对序列中的每个项目进行评估的。 使用fn:subsequence和可选的fn:count应该更高效,并绕过你的问题:

let $items := (1, 2, 3)
return xdmp:spawn-function(function () {
   xdmp:log(subsequence($items, 3, count($items))) (: you can omit 3rd param with same effect :)
})

HTH!


The example for the docs of fn:last() is showing a very similar usage of this function. The downside for using functions in predicates is though that they are evaluated for each item in the sequence. Using fn:subsequence and optionally fn:count should both be more efficient, and by-pass your issue:

let $items := (1, 2, 3)
return xdmp:spawn-function(function () {
   xdmp:log(subsequence($items, 3, count($items))) (: you can omit 3rd param with same effect :)
})

HTH!
