Re: Re: Using a DLL built with cygwin in VC++
First of all, have you read the Cygwin FAQ (specifically, *all* the questions in the Programming FAQ? Read the caveats about linking Cygwin DLLs into VC++ programs. Specifically, Q 16. After you have understood what you're actually trying to do, you may want to try to follow the instructions in Q 16 to generate your .lib and .def files, and then make sure to put in the correct crt hooks, etc. I've read all of the Cygwin's programming faq, I've tried the method they described in How can I build a relocatable dll?, first of all, there's no __imp_reent_data symbol in Cygwin dll, but there's reent_data, I used it instead, I've successfuly compiled and linked, but when I run my app I get an access violation writing at address 0x0, VS2005's debugger says that it's cygwin.dll is trying to do so. Then, I tried to remove all Cygwin API calls from my gcc compiled DLL and recompiled my app, everything worked fine. This exception occurs only if there're Cygwin API calls in DLL. So, what shall I do ? -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/

Using a DLL built with cygwin in VC++
Hello, I'm trying to use a DLL created with cygwin in my VC++ project. I have a DLL file and I need to create .lib in order to use the DLL in VC++, I use the following command sequence: dlltool --export-all-symbols --output-def mylib.def mylib.dll #cygwin's dlltool lib /DEF:mylib.def /OUT:mylib.lib #VC++'s lib Then, I link my VC++ application using the mylib.lib, but the linker says: mylib.lib : fatal error LNK1127: library is corrupt What should I do ? -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
