I've looked in the manuals (info gcc) and I sort of understand that you can get gcc to make multiple versions of its libraries, and then control them with flags (e.g -mbig-endian) or with alternate spec files. However, what always bothers me is that most toolchains incorporate a C library, and as far as I can tell, this is not multi-lib aware and so I don't see how you can get the C library to switch. So for example if you build glibc little endian, and then you needed to build a 'hello world' big-endian where would the big-endian libc come from ?? Regards, Stuart ------ Want more information?
