Hello,
I am trying to cross compile GCC 4.6.2 on cygwin terminal (32-bit) on
windows 10 (64-bit). The GCC version installed on Cygwin is 4.7.3 (to have
better compatibility).
These are the steps, I used to cross compile the GCC:
# setting of variables
export PREFIX="$HOME/opt/cross"
export TARGET=i686-elf
export PATH="$PREFIX/bin:$PATH"
export sysroot="$HOME/sysroot"
export host=i686-pc-linux-gnu
#Binutils
../binutils-2.22/configure --target=$TARGET --prefix=$PREFIX
--with-sysroot=$sysroot --disable-nls --disable-werror --disable-multilib
make
make install
#GCC
../gcc-8.3.0/configure --target=$TARGET --prefix="$PREFIX" --disable-nls
--enable-languages=c,c++ --without-headers --disable-werror
--disable-multilib
make all-gcc (FAILED !!)
While making for GCC without headers (1st part of GCC), I am getting the
following errors -
checking whether read-only mmap of a plain file works... yes
checking whether mmap from /dev/zero works... no
checking for MAP_ANON(YMOUS)... yes
checking whether mmap with MAP_ANON(YMOUS) works... no
checking whether to enable maintainer-specific portions of Makefiles... no

Does anybody has any idea, why this error is occuring ?
I also added "CXXFLAGS=-msse4.1" in Configure command in gcc, But it
doesn't help.
