Hi,
When I build gcc 6.2 following
http://clfs.org/view/clfs-embedded/x86/cross-tools/gcc-static.html on Ubuntu
19.04<http://clfs.org/view/clfs-embedded/x86/cross-tools/gcc-static.html%20on%20Ubuntu%2019.04>
using gcc 8.3,
The error below occurred. Can anyone tell me how can I resolve this problem?
Thanks.
