Not compile when using app.mk

[inochisa]

Can not compile a project using app.mk (e.g. zknAes). The linker output the following error:

This can be solved by removing MEMORY section in the link script. But I am not sure what happens to this.

hmm weird.

it works for me (just had to fix another bug about bad cast).
I'm using :
riscv64-unknown-elf/15.2.0

Maybe the issue is that you use riscv64-elf instead ?
as those binaries are made to be used in baremetal.

Yes, only a small bad cast is needed to be fixed.

This is kind of weird as both riscv64-elf and riscv64-unknown-elf. I am not sure the gcc binary from archlinux has some extra fix or the the binary you used has something others. Sometimes the riscv gcc is like a magic. XD

I will try again to see if there is something that leads to this.

[Dolu1990]

Overall, this error look for me it may be fixed if you add the -mcmodel=medany flags in gcc. (but not sure)

[Dolu1990]

Hooo no, forget it, -mcmodel=medany is already activated :/

[inochisa]

Hooo no, forget it, -mcmodel=medany is already activated :/

Maybe the riscv-elf-newlib from archlinux may be not compiled with -mcmodel=medany. I will figure it out.
