This would suggest the produced program severely botches the DOS box. Does this happen with a trivial one-liner, like hello world? Btw, do you really use the above command line to compile C++ programs? Most programs won't link without -lstdcxx, unless you don't use any C++ classes and operators; even cin and cout need that library. So I'm curious: how *did* you compile your C++ programs, exactly? > DPMI memory available: 7639 kb > DPMI swap space available: 10101 kb > > Machine has 40 MB RAM installed. Don't pay attention to what go32-v2 reports on NT: the NT DPMI server lies to it about the amount of memory it can allocate to DPMI clients. If you want to know the truth, throw together a small program that allocates memory in chunks slightly smaller than 4KB, and make it report how many chunks it succeeded to allocate before malloc returned NULL. Then multiply by 4KB, and you get the amount of available DPMI memory. > It means, DPMI is indeed, being loaded. If go32-v2 and the compiler can run, then the DPMI services *are* loaded. The error message you cite actually tells something else: it says that DPMI services are on, but there's not enough DPMI memory to even start the program. Based on what you tell, I would guess that the program you try to run screws the DOS box so badly that it is wedged for all practical purposes after that. The question is why. You will have to dig deeper to understand that. Post your findings here, if you cannot figure them out.
