Our application is a 3-tier Architecture with PB 10.5 as Front End ,C++ component deployed in EAServer 5.5. as Middletier and Oracle 10g as the backend. The middle tier in the existing system is running in SOLARIS and we are migrating to WINDOWS 2003. Business logic is done by C++ components deployed in the EAServer. To regenerate the components we are using the following environment, IDE - Visual Studio 2005 Compiler - VC 8.0 But there is one specific C++ component, which is using lots of UNIX IPCs and there are many interdependencies between files. So to build that component ,we are using CYGWIN environment. Cygwin is a Linux emulator , using which the UNIX code can be cross compiled to build the exe to run in the windows environment. Our application is depending on the third party libraries Roguewave and EAServer libraries. For creating the exe of the component in CYGWIN, we are using EAServer includes and libraries of Windows environment. CYGWIN ENVIRONMENT VERSION : CYGWIN_NT-5.0 EAServer Version : 5.5 gcc compiler :3.3.4 Roguewave for CYGWIN :10.0 Sample piece of code from Makefile, $(LINKER) -o $(BUILD_TARGETS) *.o -L/cygdrive/c/check -ljcppExtProcess -ljcc -ljutils jcppExtProcess, jcc, jutils are windows dlls. We are able to create the exe,but the exe is not working. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 1 [main] cvbura 7500 _cygtls::handle_exceptions: Exception: STATUS_ILLEGAL _INSTRUCTION 19572 [main] cvbura 7500 open_stackdumpfile: Dumping stack trace to cvbura.exe ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Please find the attached trace file(using strace command in CYGWIN environment) and the stack dump file. Doubt 1. Is EAServer libraries are compatible in CYGWIN environment? 2. Do we need to include the UNIX EAServer libraries (means .so and .a )or Windows EAServer (.dll and lib) build the exe in CYGWIN?
