stages riscv64

[minou666]

I wanted to create a stage3 for the BeagleV which uses a riscv64 but couldn't get crossdev to create the cross compiler.

I was able to do that on gentoo as well as create the whole stage3. I am also able to chroot into in using fchroot. I am then able to emerge programs in the chroot

I used the cross compiler to do the whole thing.

riscv64-unknown-linux-gnu-emerge --ask @system

and add a few extra program like my favorite editor joe

 

I had to change one line for the ebuild to get it to work on gentoo

PYTHON_COMPAT=( python3+ )
to PYTHON_COMPAT=( python3_{6..9} )

Any idea how to get crossdev to work for riscv64 on funtoo?

I followed the instruction for how to do it on funtoo, it failed emerging cross-gcc-stage1

On gentoo gcc is 10 so I tried with a requirement to use gcc 10 with identical results

checking if mkdir takes one argument... no
--with-arch=znver1 is not supported.  The argument must begin with rv32e, rv32i, rv32g, rv64i, or rv64g.
