WM6.1 下动态库加载不上与coredll有关问题

WM6.1 下动态库加载不上与coredll有关问题 [复制链接]

动态加载库，在WM6.0下是完全没有问题的  是在多普达上做的一系列测试
现在换成WM6.1（同样是多普达手机）就加载不上，出现以下问题
Data Abort: Thread=840d40a8 Proc=804e88f0 'TestFor.exe'
AKY=00800001 PC=8003bf78(NK.EXE+0x0003bf78) RA=00000238(???+0x00000238) BVA=78eba000 FSR=00000007

测试代码：
TestFor.cpp : 定义控制台应用程序的入口点。
//

#include "stdafx.h"
#include
#include
int _tmain(int argc, _TCHAR* argv[])
{
  FILE *fp= fopen("t.txt","w");

  HINSTANCE hsdl = LoadLibrary( _T("cygavutil-49.dll")); // cygavutil-49.dll  要加载的库
  if(hsdl == 0)
fprintf(fp,"%s\n","failed!");
  return 0;
}

现状PS：有的库能加载有的库不能加载，
很简单的思路就是用PE分析工具分析了一下能加载的库和不能加载的库的区别:下面我贴一下我分析的两个你能加载的库和不能加载的库的分析结果
SDL.dll(能加载，但是编译环境未知)

问题：
三个文件中能加载的两个dll的共性是将输出表和输入表都放在了.rdata里面，（但是理论上放到哪个节都无关紧要，重要的是节的属性要一致），这是由编译器和连接器决定的还是由加载机制决定的？这个能影响动态加载能否成功吗？微软是分开放的，将输出表放在edata里面，输入表放在idata里面

zzqqking · 发表于2008-12-18 00:17

既然在WM6.0下是完全没有问题的，就说明这个dll是可用的，那就不是将输入输出表的问题，否则在WM6.0下也用不了
看看是不是内存的问题，WM6.1也是ce5的内核，所有的dll都存在slot1

加载dll过大或者过多都可能失败，至于输入输出表放在哪个段是完全没有关系的，导入表由于要重定位，是需要RW的，所以单独放一个RW段更加合理

既然在WM6.0下是完全没有问题的，就说明这个dll是可用的，那就不是将输入输出表的问题，否则在WM6.0下也用不了
看看是不是内存的问题，WM6.1也是ce5的内核，所有的dll都存在slot1

当执行一个应用程序时，内核将这个应用程序调用的系统DLL加载到Slot 1（0x0200 0000－0x03FF FFFF）。
在Windows CE.NET中Slot 1专用于XIP DLL使用

应用程序用到的dll也放在这里吗？

应用程序用到的dll放在Slot0 但是所有Dll的空间是共享的，msdn有篇文章是讲这个问题的

如果DLL很大，最好把DLL静态连接到EXE
