I built the gcc toolchain with --enable multilib as mentioned in https://docs.sel4.systems/Hardware/rocketchip.html.
While building Sel4 test (after running ninja) I get the following error,

~/sel4/build$ ninja

Since I am very new to this, I hope that I can get some help with this problem.

Also these are the environment variables,
swetha@swetha-Inspiron-5570:/sel4test/build$ echo $RISCV
/opt/riscv
swetha@swetha-Inspiron-5570:/sel4test/build$ echo $PATH
/opt/riscv/bin:/home/swetha/.local/bin:/home/swetha/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin

I don't know anything about sel4. If you are having a problem with that, you should probably ask the sel4 folks.

You didn't show the gcc command that failed. There should be a /usr/include/features.h in the sysroot and the compiler should have found it. Try debugging the build a bit. However, I would expect riscv-pk to be built by an embedded elf compiler not a linux compiler. I don't know if using a linux compiler to build it can work.
