RE: Newbie question - tmpnam error

[Kalai Narayanan-SSI <kalai dot rajah at ssi dot samsung dot com>]

Yann,
 I have a redhat system. I'll try removing the CT_BUILD_PREFIX and try building it once again. 

 Btw, for the new build, I don't want to create another .config once again - but just use the previous one with modification to the CT_BUILD_PREFIX variable - how do I do it?

What host distro do you use?

No, you want crostool-NG to use the native compiler to natively build the tools. Your cross-gcc et al. are built natively. See:

Hmm. Never saw those so far. No clue... :-(

crosstool-NG does not have aarch64 (aka arm64) support for now. Sorry.
