Bug ID: 100945
Summary: Building gcc fails because mthumb\r unrecognized
option
Product: gcc
Version: 11.1.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: kclifford at tranaptic dot ca
Target Milestone: ---
I'm building gcc 11.1.0 with
host=i686-w64-mingw32
build=x86_64-pc-cygwin
config-ml.in parses the output of "arm-eabi-gcc --print-multi-lib". Because the
build machine is cygwin it thinks the line end is \n but the host is mingw and
the line end is \r\n so the building of $flags using sed leaves behind a \r
which is interpreted as part of the resulting flag.
In two places in config-ml.in I modified:
flags=`echo $$i | sed -e 's/^[^;]*;//' -e 's/@/ -/g'`
to
flags=`echo $$i | sed -e 's/^[^;]*;//' -e 's/@/ -/g' -e 's/\r//g'`
which fixed the problem.
As an additional note the same problem occurred on 10.2.0 but I didn't get to a
fix on that version.
