gcc 2.95 has a different C++ ABI than gcc 3.2.3. You'll have to build/link all C++ code with the same compiler. ------------------------------------------------------------------------- From: Sagar Shah <sagars at dpsl dot net> To: gcc-help at gcc dot gnu dot org, cygwin at cygwin dot com Date: Tue, 15 Jul 2003 14:43:41 -0700 Subject: gcc on cygwin Hi all, i had developed an application that uses libraries like libgnome, libgnomecanvasmm, libbonobo etc. i have used wstring effectively in my application, the application is running on Linux. the same application i tried to built on Windows using cygwin with development versions of autotools, gcc 3.2.3 etc. what i observed is a strange, that gcc 3.2.3 doesn't have wstring support, i searched through google for the solution and reasons, what i concluded, no support for wstring on cygwin platform. and when i tried using 2.95.x version the sample application of wstring worked properly, but when i tried to built my application using gcc 2.95, many undefined references for code that is implemented in my library files libbonobouimm, gtk-win32 etc what i think is since i have built them using gcc 3.2.3, gcc 2.95 is not getting them. well i want to know is my guess right, if yes what should i do for it. Any Help would greatly be appreciated. TAI Regards Sagar Shah
