More debugging showed where the error was:
In the misc.c around line 161
FARPROC apr_load_dll_func(apr_dlltoken_e fnLib, char* fnName, int ordinal)
{
if (!lateDllHandle[fnLib]) {
lateDllHandle[fnLib] = LoadLibrary(lateDllName[fnLib]);
if (!lateDllHandle[fnLib])
return NULL;
}
if (ordinal)
return GetProcAddress(lateDllHandle[fnLib], (char *) ordinal);
else
return GetProcAddress(lateDllHandle[fnLib], fnName);
}
The LoadLibrary("kernel32") returned NULL, which caused the problem.
The error code is 126, can not find the module kernel32 ? why it can not
find the kernel32.dll, it is in the c:\windows\system32 ...
Anyone can help me out?
Thanks,
Lijuan
