Hi everyone, I'm new to the world of gcc.
I don't know if this is the right place to post, but I'm having some
issues that are really annoying.
I've created a Unix-like system, and although it's not very complete
yet, I want to make a cross-compilation chain for it so that I can use
some open source c libraries.
I modify these files:
config.sub, fixincludes/mkfixinc.sh, config.gcc, gcc/config/caffeinix.h,
libgcc/config.host
But after I compiled gcc, I ran into problems when I ran it.
I tried to compile a test file (it has nothing but the main function),
but I got the following error:
❯ ./riscv64-caffeinix-gcc -o test test.c
Assembler messages:
Fatal error: invalid -march= option: `rv64imafdc_zicsr'
Information I can provide:
Host: Ubuntu 22.04
Newlib (compiled by myself): 2.5.0
And the compiled gcc information:
❯ ./riscv64-caffeinix-gcc -march=rv64gc -Q --help=target
[ ... ]
Assembler messages:
Fatal error: invalid -march= option: `rv64gc'
❯ ./riscv64-caffeinix-gcc -v
More important would be to see the -v output when you ran the compiler
and got the error message from the compiler. Most likely it's not
finding a risc-v assembler.
