Bug ID: 110607
Summary: Makefile.in build broken build-tools when CXXFLAGS is
defined
Product: gcc
Version: 12.1.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: driver
Assignee: unassigned at gcc dot gnu.org
Reporter: sagebar at web dot de
Target Milestone: ---
This part in the main makefile:
> 177 # These variables must be set on the make command line for directories
> 178 # built for the build system to override those in BASE_FLAGS_TO_PASS.
> 179 EXTRA_BUILD_FLAGS = \
> 180 CFLAGS="$(CFLAGS_FOR_BUILD)" \
> 181 LDFLAGS="$(LDFLAGS_FOR_BUILD)"
Should instead be:
> 177 # These variables must be set on the make command line for directories
> 178 # built for the build system to override those in BASE_FLAGS_TO_PASS.
> 179 EXTRA_BUILD_FLAGS = \
> 180 CFLAGS="$(CFLAGS_FOR_BUILD)" \
> 181 CXXFLAGS="$(CXXFLAGS_FOR_BUILD)" \
> 182 LDFLAGS="$(LDFLAGS_FOR_BUILD)"
Since some components of the build system are compiled as c++, if one wants to
define custom CXX-flags in cross-compilation situations, these flags then also
get used when building build-tools (which causes breakage)
