Hi,
I build binutils-2.23.2, gcc-4.8.1, newlib-2.0.0 in Cygwin:
1. Full install cygwin.
2. Run cygwin.
3. CC="gcc -B/usr/bin"
4. /src/binutils-2.23.2/configure --target=arm-elf
--prefix=/gnutools/arm-elf --enable-interwork \
--enable-multilib -v 2>&1 | tee configure.out
5. make -w all install 2>&1 | tee make.out
6. PATH=/gnutools/arm-elf/bin:$PATH; export PATH
7. /src/gcc-4.8.1/configure --target=arm-elf --prefix=/gnutools/arm-elf
--enable-languages="c,c++" \
--enable-interwork --enable-multilib --with-gnu-as --with-gnu-ld
--with-newlib \
--with-headers=/src/newlib-2.0.0/newlib/libc/include -v 2>&1 | tee
config.out
8. make -w all-gcc install-gcc LANGUAGES= 2>&1 | tee make.out
It stoped and displayed:
checking for clock_t... yes
checking for F_SETLKW... yes
checking if mkdir takes one argument... no
*** Configuration arm-unknown-elf not supported
Makefile:3860: recipe for target `configure-gcc' failed
make: *** [configure-gcc] Error 1
I don't know what's wrong and how to resolve it. If I use --target=i386-elf
or arm-eabi, I can build the toolchain. But why arm-elf can't?
Best regardes
eMartian

arm-elf support was obsoleted in gcc-4.7 and dropped in gcc-4.8.
R.
