Dear Sir,
I would like to build RISC-V g++ and gfortran compiler by downloading all
source codes to host pc (for linux OS) and then rebuild compiler from
scratch. I can build RISC-V gcc compiler from scratch by downloading to
host pc using https://crosstool-ng.github.io/ However, I have not
found any such cross compiler tool for g++ and gfortran. May I request you
to guide me on how to build RISC-V cross C ++ and gfortran compiler from
source codes?
I look forward to hearing from you soon.
Thanking you.
Sincerely,
-Vijay

The same way. The C, C++ and Fortran compilers are all part of the
same source tree.

Moreover, in cross-ng tool (https://crosstool-ng.github.io/) in ct-ng
menu-config there are no option to build C++ and gfortran for RISC-V
architecture. This thing is, I need to modify certain source codes in the
source tree and rebuild both C++ and gfortran for RISC-V architecture. So,
I am looking for a command or tool or config file which will allow me
download all source files for C++ and gfortran compilers, modify certain
part of source code in source tree and re build the compiler from scratch.
I request your assistance in this regard.
Many Thanks.

Using ct-ng menuconfig, in the C compiler menu, I see tick boxes for
C++ and Fortran.

Thanks Jim. Yes, I can see C++ and Fortran for new version of crosstool-ng.
However, I am unable to generate .config file using the following
instructions:
Enable newlib build (C-library section)
Enable "Build a multilib toolchain" (Target options section)
and also
selected C++ (C compiler section)
as mentioned in
https://gist.github.com/franzflasch/02a8aeb2f6ec8e942b14ee9929db38e9
I have attached my version of .config file which I build gcc from scratch.
May I request you to edit this file send me two .config files? One for C++
and other fortran.
Many Thanks.

What exact problem do you run into?

I respectfully decline. I don't have such .config files and have no
interest in generating them.
If you can't figure out how to use crosstool-ng, you could try using
github.com/riscv/riscv-gnu-toolchain instead. Or maybe download a
prebuilt toolchain which is available from various sources like
sifive.com/boards.

Never mind, I have generated config files for C++ and fortran. Thanks for
your time Jim.

Hello Jim and All,
How do I
build riscv32-unknown-elf-dramfs-c++, riscv32-unknown-elf-dramfs-gcc,
riscv32-unknown-elf-dramfs-gfortran,
etc. using crosstool-ng is there any config file(s)?
Many Thanks,
-Vijay

I'm not familiar with dramfs and don't know what you are asking for
there, but an embedded elf toolchain can be built with crosstool-ng.
There are sample config files for riscv32-unknown-elf and
riscv64-unknown-elf.
