use CC not CXX to compile abc

[rxrbln]

Compiling Yosys w/ "make CC=gcc CPP=cpp CXX=g++ PREFIX=/usr docdir=/usr/doc/yosys ABCREV=default" I otherwise get:
/usr/lib64/gcc/x86_64-t2-linux-gnu/8.1.0/../../../../x86_64-t2-linux-gnu/bin/ld: src/base/main/mainInit.o: in function Abc_FrameInit': mainInit.c:(.text+0xcf): undefined reference to Glucose_Init(Abc_Frame_t_)'

You might want to revisit #285 and see if it is still relevant.

Well, it occurs with yosys f02623a from some weeks ago as packaged in #t2sde (https://t2sde.org/packages/yosys), compiling natively. Looks like C++ symbol mangling vs. plain C. gcc vs. g++ mismatch, ..?

Actually it will be enough to use make CC=gcc CXX=gcc PREFIX=/usr docdir=/usr/doc/yosys ABCREV=default"
This way you would replicate exactly what yosys is doing inside it's Makefile
Or even better do it two-step:
make config-gcc
make PREFIX=/usr docdir=/usr/doc/yosys ABCREV=default"

not really best practice, right?

[mmicko]

Right, but issue is on abc compile side, and mixing C and C++ there, and you were right, name mangling is actual problem there
