Numerous changes over the last few days. Please pull the latest from github before proceeding. When I compile on Dave s system using Sun C ( 5.12), I needed to change the line endings to LF from CR-LF. If dos2unix took a list of filenames to convert in-place then we d merely do: $ dos2unix makefile *.txt *.c *.h */*.h */*.c Since dos2unix doesn t work like I d hope, we can get around this with unzip: $ unzip aa master.zip $ mkdir temp $ cd temp $ unzip ../master.zip $ cp simh-master/VAX/*.bin simh-master/VAX/*.exe ../simh-master/VAX/ $ cd ../simh-master $ /opt/csw/bin/gmake vax GCC=/opt/solarisstudio12.3/bin/CC Hitting an issue when using SunCC from Solaris Studio now: bash-3.2$ /opt/csw/bin/gmake vax GCC=/opt/solarisstudio12.3/bin/CC lib paths are: /lib /usr/lib using libm: /lib/libm.so using librt: /lib/librt.so using libpthread: /lib/libpthread.so /usr/include/pthread.h using libdl: /lib/libdl.so /usr/include/dlfcn.h using libpcap: /usr/include/pcap.h *** *** vax Simulator being built with: *** - compiler optimizations and no debugging support.
