That is a cross-built native compiler. To build that you need to have a cross-compiler already. You want to just do a $SOURCE_DIR/configure --prefix=$PREFIX --target=$TARGET and no --host, and the other configure options only after you have seen you do need them. > Make command stops: > > arm-linux-gnueabihf-gcc -g -O2 -O2 -g -O2 -DIN_GCC -W -Wall > -Wno-narrowing -Wwrite-strings -Wcast-qual -Wstrict-prototypes > -Wmissing-prototypes -Wold-style-definition -isystem ./include -fPIC > -fno-inline -g -DIN_LIBGCC2 -fbuilding-libgcc -fno-stack-protector > -fPIC -fno-inline -I. -I. -I../.././gcc > -I/gcc-host/source/gcc-14.2.0/libgcc > -I/gcc-host/source/gcc-14.2.0/libgcc/. > -I/gcc-host/source/gcc-14.2.0/libgcc/../gcc > -I/gcc-host/source/gcc-14.2.0/libgcc/../include -DHAVE_CC_TLS -o > pr-support.o -MT pr-support.o -MD -MP -MF pr-support.dep -fexceptions -c > /gcc-host/source/gcc-14.2.0/libgcc/config/arm/pr-support.c > -fvisibility=hidden -DHIDE_EXPORTS > /gcc-host/source/gcc-14.2.0/libgcc/config/arm/pr-support.c: In function > '__gnu_unwind_execute': > /gcc-host/source/gcc-14.2.0/libgcc/config/arm/pr-support.c:260:45: > error: '_UVRSC_PAC' undeclared (first use in this function); did you > mean '_UVRSC_FPA'? > 260 | if (_Unwind_VRS_Pop (context, > _UVRSC_PAC, 0, _UVRSD_UINT32) > > | ^~~~~~~~~~ > > | _UVRSC_FPA This is defined in ginclude/unwind-arm-common.h . Figure out why that isn't included in your config? Or maybe it already works better if you no longer do superfluous and/or cargo-cult configure options :-) Segher
