10 years ago I believe this error has to do with a new version of GCC. I was able to compile successfully after making a slight change, as seen in commit 221336091ec99e8814b791a9135ae3ea73e14746
It was just moving the #define BIT from qemu/hw/eepro100.c to qemu/qemu-common.h
I have a problem while trying to run step 2 of the MARSSx86+DRAMSim2 configuration (Go into the marss folder and type scons dramsim=/full/path/to/DRAMSim2). I have successfully resolved all previous dependency issues by installing necessary packages.
I get an undefined reference to BIT in kvm.c
