e seen is that it has something to do with propagating exceptions in multithreaded programs. However, Qt doesn't use exceptions, so unless you use them yourself, it shouldn't be a problem. I haven't had any problems with the DLL removed, and many others haveРreported smooth sailing as well. However, this could create problems if you use exceptions andРthreads in your program.РAs far as I know piled multithreaded applicaions should always be dynamically linked to mingwm10.dll, so this file should be available puters running the application. It seems that U++ somehow removes this nasty limitation. How is that possible?РTechnorati : gnu, mingw РDel.icio.us : gnu, mingw РIce Rocket : gnu, mingw РFlickr : Рgnu, mingw РZooomr : gnu, mingw Р : gnu, mingw РRiya : gnu, mingw Р43 Things : gnu, mingw
