Generally, yes. As Yann explained, the CT_CC_... variables are only used to build gcc itself; they are not set when you use the built gcc to build other projects. The "export ..." method should work, although you might want to try it with the defaults first -- the Linux kernel, at least, should be pretty smart about picking the right flags for the various hardware targets. Picking other flags could very well lead to instability. (There was an issue with "-Os" on some platforms for quite a while, and that's even a fairly standard Linux kernel config option.) Also note that having a toolchain, or even a toolchain and a kernel, is only a small part of building a fully distribution that can run on a given platform. It's been covered here before, e.g.; http://sourceware.org/ml/crossgcc/2013-03/msg00008.html If this level of indirection makes you uncomfortable, you might see if one of the "distribution building" tools (yocto, etc) has your platform as a target. Either way, good luck! Best regards, Anthony Foiani -- For unsubscribe information see http://sourceware.org/lists.html#faq
