Dear cygwin AT cygwin DOT com,
I saw this problem was raised for few times on list, but do not see
final solution. I want to create native Windows frontend to
cygwin-based dynamic library.
What I did:
1. I did DLL, it works fine with cygwin application.
2. If I try to use it from native application it hangs on LoadLibrary.
3. I did DllMain function with impure_ptr initialization and finally
compiled as described in FAQ.
4. Now DLL loads and simple functions (for example strcpy()/ctrcat()
based) work OK, but any "syscall" from DLL to cygwin
function (for example printf()) causes NULL pointer reference.
Is subj possible? May be some additional initialization is required?
