Cross-compile arm32 toolchain with hard float, but Error in gcc final
Details of cross toolchain：
TARGET="arm-linux-gnueabihf"
HOST="$(gcc -dumpmachine)"
BUILD="$(gcc -dumpmachine)"
1、 GCC FIRST:
CFLAGS_FOR_TARGET="${-march=armv7-a -mhard-float}"
CXXFLAGS_FOR_TARGET="${-march=armv7-a -mhardfloat}" ./configure --build=$BUILD
--host=$HOST --target=$TARGET --without-headers --with-newlib
make -j 16 && make install
this step is OK
2、GLIBC HEADER
CC="arm-linux-gnueabihf-gcc -mhard-float"
$ROOT_TAR_SRC/$EGLIBC/configure --with-float=hard --with-fp
this step is OK
3、GCC SECOND
CFLAGS_FOR_TARGET="${-march=armv7-a -mhard-float}"
CXXFLAGS_FOR_TARGET="${-march=armv7-a -mhardfloat}" --enable-shared
this step is OK
4、GLIBC
CC="arm-linux-gnueabihf-gcc -mhard-float"
$ROOT_TAR_SRC/$EGLIBC/configure --with-float=hard --with-fp
this step is OK
5、GCC Final
CFLAGS_FOR_TARGET="${-march=armv7-a -mhard-float}"
CXXFLAGS_FOR_TARGET="${-march=armv7-a -mhardfloat}" --enable-shared
compier error：the error is checking libgcc terminated。 the checking log at
File， the reason is stubs.h， but I add the option -mhard-float. How I solve
this Error?
