Hi all, I am working on a project that requires mixing linux code with windows code. I have a lot of code that is already written for linux and it compiles fine under cygwin, but I need to use it under windows so that I can have access to a MATRIX Vision camera that has drivers only for windows. The CD that came with the camera installed the drivers along with libraries that allow me to interface with it. The example code runs fine in Visual Studio. In cygwin with gcc, to compile and link against the dll I link against two .lib files that came with the camera's software using these commands: gcc -c -g -mwindows -I./include/ -o ./Build/mvTest.o ./src/blah.c gcc -o ./bin/mvTest ./Build/mvTest.o $(LIBS) Where $(LIBS) is: LIBS=./lib/mvDeviceManager.lib \ ./lib/mvDisplay.lib \ -lpthread The simple test code I have compiles and links against these libs (and headers) with no problems. But when I run it it crashes, and gdb gives me this output: --------- $ gdb ./bin/mvTest.exe GNU gdb 6.3.50_2004-12-28-cvs (cygwin-special) Copyright 2004 Free Software Foundation, Inc.

Exit anyway? (y or n) y -------- This same code runs fine in Visual Studio. Is this problem just something that cygwin can't solve? Or is there something I could try to get this to work? My cygwin configuration is attached. Any helpful suggestions would be GREATLY appreciated as I'm running out of time to get this working. -- Greg Slepak Software Developer CIMAR @ University of Florida
