Bug ID: 110716
Summary: failed to build cross gcc 10.5 with host gcc 4.6.3
Product: gcc
Version: 10.5.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: bootstrap
Assignee: unassigned at gcc dot gnu.org
Reporter: anmin_deng at yahoo dot com.tw
Target Milestone: ---
I tried to build a cross gcc-10.5 for ARM target on a linux host/build with
gcc-4.6.3.
Previously in May, I successfully built cross gcc-10.4 for ARM target on the
same linux host/build, but now in July the very same procedure and options
failed for building gcc-10.5.
(possibly gcc-10.5 source added with some C++ features not supported by
gcc-4.6.3?)
The building error messages==>
