Error compiling Verilog examples with Yosys 0.37 on Mac OS

[frantic0]

Hello,

I have been trying to compile and upload with the latest Yosys 0.37+34 oss-cad-suite-darwin-x64-20240127.tgz on Mac OS Sonoma 14.2

I can successfully compile and upload the blink verilog examples but not the pll, pwm_rainbow, usb_acm_device examples, which are of interest.

I am adding the result of the make on pll. Any ideas of what is not working?

Thank you

$ make
ecppll -i 48 -o 100 -f pll.v
Pll parameters:
Refclk divisor: 12
Feedback divisor: 25
clkout0 divisor: 6
clkout0 frequency: 100 MHz
VCO frequency: 600
yosys -s "plltest.ys"

install gnu make with brew install make and then build using gmake instead of make

Thank you @jrsa

not sure why, but the makefile entry for generating the .ys files wasn't working for me.

I was able to build it with make by changing the makefile and replacing the following

%.ys: $(VERILOG_FILES)
 	$(file >$@)
 	$(foreach V,$(VERILOG_FILES),$(file >>$@,read_verilog $V))
 	$(file >>$@,synth_ecp5 -top $(TOP_MODULE)) \
 	$(file >>$@,write_json "$(basename $@).json") \

with this

%.ys: $(VERILOG_FILES)
	@echo "Generating Yosys script $@"
	@echo "read_verilog $(VERILOG_FILES)" > $@
	@echo "synth_ecp5 -top $(TOP_MODULE)" >> $@
	@echo "write_json $(basename $@).json" >> $@

it's most likely because something in the original makefile is only supported by GNU make, and not by BSD make which is what ships with OS X
