When building GCC cross-compiler for a freestanding environemnt, "__float128 is not suppported for this target" is reported as an error when you include . How can you eliminate this error
I built and configured the the GCC cross-compiler like so
export PREFIX="$PWD/opt/cross"
export TARGET=i686-elf
export PATH="$PREFIX/bin:$PATH"
# Configure, build, and install the GCC cross-compiler
git clone git://gcc.gnu.org/git/gcc.git gcc
mkdir build-gcc
cd build-gcc
../gcc/configure --target=$TARGET -- prefix="$PREFIX" --disable-nls --enable-languages=c,c++ --without-headers --disable-hosted-libstdcxx
make all-gcc
make all-target-libgcc
make all-target-libstdc++-v3
make install-gcc
make install-target-libstdc++-v3
And when I try to include #include <cstddef>, I get the following error
In included file: __float128 is not supprted on this target
Note: I should add that my program compiles just fine. Even with all warnings turned on.
