Dear Sir,

I am working on Open Source Risc-V on the Xilinx Artix-7 35T Arty.
I did all the steps which was given in the procedure, but facing following error.
"riscv64-unknown-elf-gcc: error: unrecognized command line option '-V'"

While executing make Hello word, I got following error, Which I could not rectify.
Following config.log file executed when I tried to make hello word program.

This file contains any messages produced by compilers while
running configure, to aid debugging if configure makes a mistake.

It was created by freedom-metal configure v0.1.2, which was
generated by GNU Autoconf 2.69. Invocation command line was

$ /data2/Risc-V/freedom-e-sdk/freedom-metal/configure --host=riscv64-unknown-elf --prefix=/data2/Risc-V/freedom-e-sdk/bsp/freedom-e310-arty/install --libdir=/data2/Risc-V/freedom-e-sdk/bsp/freedom-e310-arty/install/lib/debug --disable-maintainer-mode --with-preconfigured --with-machine-name=freedom-e310-arty --with-machine-header=/data2/Risc-V/freedom-e-sdk/bsp/freedom-e310-arty/metal.h --with-machine-ldscript=/data2/Risc-V/freedom-e-sdk/bsp/freedom-e310-arty/metal.default.lds --with-builtin-libgloss

Please help me from beginers stage.

On x86_64, & gcc-8.3.0, there is no option '-V'

Run 'gcc --version' to get your gcc version. Development and testing is more than limited on the more exotic architectures. You may have saved in buying yourself an Arm core, but you might have taken on a heap of trouble getting the chip built, and geiitng a credible OS together. Is this your first time working with Risc V? Post your gcc version.

I would have a look around your gcc source or anywhere you can get ideas for the oldest files. It could be expecting gcc-2.95, or something ridiculously old like that. That was the only gcc approved for kernel building at one stage in the dim distant past.

Hi There,

Thank you very much for your reply,
Yeah i am totally new to RISC V,
I run 'gcc --version' this command and got following reply,

Well for building this Project they have given us steps,and I am following those steps.
Please let me know ,where I have gone wrong.

Regards,
Sagar

What's the date of those instructions?
/begin boring history
RISC was a big thing in the 1990s, because it was felt you could miniaturize the cpu core and do clever stuff there perhaps getting speeds up. To do that with ancient design ideas, some saw RISC (Reduced Instruction Set Computers) as the way forward. You have to understand that wafer fab was comparatively huge back then. Now we have multicore CPUs with complete instruction sets doing amazing things with sub-microscopic wafer fab.
/end boring history

I don't know why there's RISC-V in 2010. If you can't get a compile in gcc, be aware that there's LLVM support also, why I dunno. Please go back to your compile. Here, gcc spits out and carries on, so that shouldn't stop you. If we can, we'll ignore it.

Dear Sir,

Even though we ignore this error,
But I am not able to execute the Hello program in Freedom-E-SDK,
Can you tell me exactly How I can tackle these errors,
As my ultimate goal is to execute the Hello program and also running the Make file for this project.

Regards,
Sagar

Who is “they”? Is this homework/schoolwork?

Dear sir,

I have made query to get solution.
If you know anything regarding this query, then do reply,
I want to execute hello program in riscv.

Please post the error you're getting.

When the compile pukes, hit up-arrow and return. that should skip to the last uncompleted line and repeat it. Post the output. That's how you solve these things.

Dear Sir,

I have install all prerequisite software required to compile a bare-metal RISC-V program.
So I am running following command,

I am getting following error

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

From this I have not understoon one point , in last path it says
/data2/Risc-V/freedom-e-sdk/bsp/freedom-e310-arty/build/debug/Makefile

In reality there is no Makefile.

Now it says please look config.log file for more details,
I am putting only error parts from config file as follows,

1. configure:2851: riscv64-unknown-elf-gcc -V >&5
riscv64-unknown-elf-gcc: error: unrecognized command line option '-V'
riscv64-unknown-elf-gcc: fatal error: no input files

2.configure:2851: riscv64-unknown-elf-gcc -qversion >&5
riscv64-unknown-elf-gcc: error: unrecognized command line option '-qversion'; did you mean '--version'?
riscv64-unknown-elf-gcc: fatal error: no input files
compilation terminated.

3.riscv64-unknown-elf/lib/crt0.o: file class ELFCLASS64 incompatible with ELFCLASS32
/usr/local/lib/gcc/riscv64-unknown-elf/7.2.0/../../../../riscv64-unknown-elf/bin/ld: final link failed: File in wrong format
collect2: error: ld returned 1 exit status

4.configure:2951: error: in `/data2/Risc-V/freedom-e-sdk/bsp/freedom-e310-arty/build/debug':
configure:2953: error: C compiler cannot create executables

This are all errors which I have seen in config.log file,

I hope I will get some productive output from Linuxquestions.org.

Warm Regards,

Please find the attached link.

I checked the link.

All these FPGA manufacturers have their own cpu cores. The idea is: Don't buy Arm IP - use ours, because it's cheap/free. So you do, you write your IP for the core which only goes in their chip. It's a way of locking in customers.

He has a Xilinx dev board, and is falling at the first hurdle. Let him post the stuff he's been asked for since post #1 if he wants help. Otherise we can go silent.

The presence of -V and -qversion in your output seems to imply that there's a problem in your makepkg.conf. Try looking in there to fix any possible errors.
