If I write a C++ program and compile it into an executable file AND, don't have to install the program, will I have trouble running that C++ written program on other platforms? Do portability issues accross different platforms only arise when I have to install the program?
I'm currently breezing through a book called Portable C++ though I'm only building a stand-alone C++ program which will use WXWidgets (which is cross platform) though I'm not sure if this is necessary.
Do I still have to address portability issues even when building a stand-alone app (executable from a flash drive) where nothing is installed and I'm not accessing system files.
Thanks to anyone who can shead shome light on this.
