Compilation with different c++17 c++14 c++11

in gnu land, it is ok to link different versions together the important part is that you must link it with the appropriate libstdc++.so version which is g++-x version dependent, i.e. don’t compile with different version of g++-x

if you do update a g++ as in the above (from v7 to v8), then you need to recompile everything

compiling from examples directory by hand

in build-unix/Makefile.config

You need to modify the following lines in Makefile.config SYSTEMC_HOME?=/home/adam/Downloads/SystemC/Core/systemc-2.3.3-c++17 TARGET_ARCH = linux64 SYSTEM_INC_DIR = $(SYSTEMC_HOME)/include FLAGS_COMMON = -g -Wall -std=c++2a

in build-unix/Makefile.rules

INCDIR += -I. -I.. -isystem $(SYSTEMC_INC_DIR)

disable version check

line 182 of $SYSTEMC_HOME)/include/sysc/kernel/sc_ver.h add the following (line 171): #define SC_DISABLE_API_VERSION_CHECK 1
