Unrecognized character error while building nexys4_ddr_ariane.o

[abdullahyildiz]

I'm trying to build FPGA bitstream of lowRISC with Ariane. I'm working on ariane-v0.7 branch.

I get the following error when riscv64-buildroot-linux-gnu-gcc tries to read from pipe:

$ make nexys4_ddr_ariane

Is this related to shell type/version?

Indeed the flow requires that /bin/sh is aliased to /bin/bash (not the default). But I cannot recall if this relates to your problem.

Yes, you are right. I forgot to change the default shell from dash to bash.
