error with extended ISA

[op21beyond]

Hi,

With default ISA (rv64imafdc), everything goes well.
But when I tried ISA=rv64imafdc_zba_zbb_zbs (RISC-V B BitManp standard extensions), many errors occur while building riscv64-unknown-linux-gnu-gcc.
some of the errors: -V option. isl/schedule.h not found. stdio.h not found. ...
Can anyone share how to solve this issue?

Hi, sorry to hear that. It seems that the last commit for RSS was made last year when these extensions were still under draft status. I assume that the error you are experiencing may be due to an out-of-date toolchain. I suggest upgrading your toolchain first or waiting for our upcoming upgrade in the next few weeks.
