Hi There,

I am integrating Python 2.7.3 into our system on Windows. We embedded Python 2.7.3 interpreter to our system.

The problem we met is, our extended Python interpreter cannot load "_socket.pyd" when "import socket" is executed, for example. Here is the error:

Traceback (most recent call last):   File "t.py", line 1, in     import socket;   File "C:\trunk1\third_party\python-2.7.3\win32\lib\socket.py", line 47, in     import _socket ImportError: DLL load failed: The specified module could not be found.

I wrote a small program as listed below to manually load "_socket.pyd" from Python 2.7.3 binary installation  on Windows, and got the same failure.

static void TestDllLoad(const char *dllPath) {     HINSTANCE socketh=LoadLibraryEx(dllPath, NULL, LOAD_WITH_ALTERED_SEARCH_PATH);     if (socketh == NULL) {

fprintf(stderr, "Failed to load shared library: %s\nError: %d\n", dllPath,  GetLastError());     } else { fprintf(stderr, "Successfully load shared library: %s\n", dllPath);     } }

int main() {     /* The following loading success. /     TestDllLoad("<PathToPython2.3.3>\DLLs\_socket.pyd");     / The following loading failed. */     TestDllLoad("<PathToPython2.7.3>\DLLs\_socket.pyd");     return 0;}

I tried MSVC 2008 and a third-party compiler, and got the same result, even after copying "python27.dll" to the testing directory from Python 2.7.3 installation on Windows.

There is a similar failure reported in http://bugs.python.org/issue4566, but it is marked as fixed and closed. 

Anyone has any idea about the problem?

Thanks a lot.
