We created a DLL using cygwin and have written a class based python
module
for the same. We have created a sample script for the class based python
module, that creates an object of the class and calls various methods in
the
class. This Test script works fine while I run it from IDLE. However
when I
run it from command prompt it either hangs or just returns without
executing
the functions. When it returns I do not get a error trace.
When I tried to findout where exactly the issue is happening. the issue
occurs when I try to call the *cygwin_dll_init* method of the
cygwin1.dll .
This cygwin1.dll is actualy a dependency to the DLL we have built. So we
have to load this DLL and call this *cygwin_dll_init* method before
loading
my DLL.
cyg = cdll.LoadLibrary("cygwin1.dll")
cyg.cygwin_dll_init() #hangs or returns here
mydll=cdll.LoadLibrary("my.dll")
mydll.func1()
I'm trying to understand what exactly is the difference, when we call it
IDLE and when we call it from command prompt using the python command. I
will have to get the script working from command prompt as well.
A few comments:
* why do you initialize cygwin1.dll in Python? If it's a dependency of
my.dll, it might be better to load and initialize it there.
* for this function prototype: void cygwin_dll_init(void);
you should declare it using:
cyg = cdll.LoadLibrary("cygwin1.dll")
cyg.restype = None
cyg.cygwin_dll_init() #hangs or returns here
...
Anyway, I don't see why a console application would fail but not inside
IDLE.
