make[3]: vivado: Command not found ../common.mk:2: recipe for target 'all' failed

Nobody has claimed this yet.

Hi
I am trying lowrisc-chip v0.7 by the command:
make nexys4_ddr_ariane

I do source the vivado path by
source /tools/Xilinx/Vivado/2018.3/*.sh
and
which vivado
do found the path of vivado.
However, I do still encounter the command not found as below.
Any hint?

Nicolas

Start with the make nexys4_ddr_ariane command and the failing invocation in fpga/xilinx/xlnx_axi_clock_converter, where tcl/run.tcl is run through common.mk. Check how the Vivado path is passed into nested make processes and confirm that vivado is available there. Done means the build reaches the next FPGA generation step without “vivado: Command not found.”
