Just use the source supplied with the Windows "uClinux 2.6 Distribution for Nios II" posted in the forum.
Remove CRs from the source-files by using dos2unix or stripcr.c included at the end of this mail (have also included a script which calls this prog.).
Build instructions:
Installdir=/usr/local/nios2-gnutools (or whatever you want)
Sourcedir contents:
binutils
gdb
gcc
make
newlib
Get rid of Cygwin inserted CRs:
./
stripcr.sh In sourcedir do:
[1] Binutils
mkdir binutils-build
cd binutils-build
../binutils/configure --target=nios2-elf --program-prefix=nios2-elf- --prefix=$Installdir --exec_prefix=$Installdir -v
make all
make install
[2] GCC
export PATH=$PATH:$Installdir
mkdir gcc-build
cd gcc-build
../gcc/configure --target=nios2-elf --program-prefix=nios2-elf- --prefix=$Installdir --exec_prefix=$Installdir --with-newlib --with-headers=../newlib/newlib/libc/include -v
make all
make install
[3] Make
mkdir make-build
cd make-build
../make/configure --target=nios2-elf --program-prefix=nios2-elf- --prefix=$Installdir --exec_prefix=$Installdir -v
make all
make install
[4] Newlib
cp newlib/newlib/configure.host.normalc newlib/newlib/configure.host
mkdir newlib-build
cd newlib-build
../make/configure --target=nios2-elf --program-prefix=nios2-elf- --prefix=$Installdir --exec_prefix=$Installdir -v
make all
make install
[5] GDB
mkdir gdb-build
cd gdb-build
../make/configure --target=nios2-elf --program-prefix=nios2-elf- --prefix=$Installdir --exec_prefix=$Installdir -v
make all
make install
Hope this is helpful
Regards
