Tossing this out in the event someone recognizes something and can point me in a direction to debug/correct the issue I am having.

Wanting to move the BBS from physical hardware to a virtual. am using VMware ESXi 6.7. I was able to convert the physical to virtual disk, can boot the disk, other applications I was running, MySQL and Apache seem to not be affected by the new virtual hardware setup. But sbbs seems to be, I keep getting illegal instruction when trying to startup the bbs services.

Thining something may have been compiled to physical CPU capabilities that didn't work on the virtual CPU, I just finishing clearing source directories and re-compiling sbbs on the virtual setup. I did not pull new source code in, just re-compiled what was present, everything compiled without errors. I still get the illegal instruction when sbbs tries to startup.

When I attempt to start sbbs, this is the console output:

Illegal instruction


Anyone run into something similar and have ideas what to do next?

Illegal instruction

Are you sure you compiled clean?

I've had that before, on x86_64 platforms thinking that compiled on 1 server should work on the other. Turned out there must have been CPU differences - so a "clean" compile resolved it for me.

yes, no doubt the compile is clean. typical warning messages but no errors.

Later today I'm going to kill off all the source directories on the VM and pull in fresh from CVS and try that.

yes, no doubt the compile is clean. typical warning messages but no errors.

new compiles again tonight, no errors during the compile, still seeing illegal instruction message to sbbs console.

found these in syslog and kern.log:

syslog <==

Weird. so i try starting without the Web Server and I have no 'illegal instruction' for a long time, and then finally:

For now I guess I keep things running on the physical hardware. Not sure what gives that it will compile fine in the virtual env but throw these errors when trying to run.

... Use it up.Wear it out. Make it do Or do without.
