Description Dominique Leuenberger 2017-06-08 12:52:30 UTC

qemu has explicit requires/patches to build using GCC6. Back in the days this was  done to favor gcc6 over 4.x/5, in order to produce smaller code.

Since TW now moved to gcc7, this is sort-of contra, as we now favor an older compiler over the current one (and the old one is likely supposed to disappear sooner or later)

It would thus be great if qemu can be built using gcc7 too

Comment 3 Bruce Rogers 2017-06-08 21:02:44 UTC

Liang, I believe what dimstar is pointing out is that we treat gcc6 as if it's the best compiler to use to solve our problem of needing a recent compiler, when in fact gcc7 would be a better choice if available. (note to readers - it's only used for compiling seabios, not other components). We should add the smarts here to require at least gcc6 for compiling seabios, but using whatever is default, if it is >= gcc6. That's what I think we should do to address this.
