...st-case. I noticed that, while linking an .exe file worked for a simple main function that calls another function, linking a DLL does not work. The /DLL parameter is not implemented (nor is /NOENTRY). I managed to add handling of the /DLL and /NOENTRY parameters to lld. /DLL successfully sets the imageType to ImageType::DLL. I added code to change the file extension from .exe to .dll. That far it worked fine and a .dll file was created. It was just then that I realized that lld does not seem to write an export section. ;-) Opening the file in Depedency Walker, I did not see my exported function. &g...

This is what we need to do: 1) Deploy 24 Windows XP VMs in parallel. 2) Boot them from a shared Windows XP C: drive. 3) Since this is a read-only shared image we obviously can''t have multiple VM''s writing to it. 4) All writes to the boot image for logging,
