#100 sky130 Makefile typo Issue opened by standanley I believe there is a small typo in the pull request merged on 1/26. I'm looking at line 160 in sky130/Makefile.in: 66e53e5#diff-110f5cdd52092b0ae64eac540e7fdc13a19e212e688d29e5420692503fd21b14R160 When adding the "libraries/" directory on the end of the --enable-sky130-pdk configuration value, it assigns the variable SKYWATER_PATH to itself using recursive assignment. This causes the error "Recursive variable 'SKYWATER_PATH' references itself". One fix is to change the = to := But I think the intended behavior might be to append a copy of the path to itself with the /libraries added. In that case, I think we should change = to += on line 160, and = to := on line 158. I'd appreciate it if someone more familiar with Makefiles and/or understanding of the intended behavior takes a look at this. RTimothyEdwards/open_pdks
