You mean XP 64-bit? (i.e. NT 5.2, right?) This is the only practical reason I can think of for using DOSBox to build anything. For sure, it would be much much faster not using DOSBox, as that is extremely slow. I've never used VMware honestly, but it should be much faster. (Heck, almost anything would be faster.) At least I would try VMware if I were you. (QEMU ain't too fast either. Not sure about others: VirtualPC, VirtualBox, BOCHS, etc., but I suspect the worse.) > I have no real need for djgpp, but it seems neat, and like everyone > else I have the hardware/software to run it, and I like to build > things myself. The only need here is targeting native DOS (although it runs on most Windows, too). If you don't like DOS or have no need / desire to compile for it, DJGPP will fulfill no need. > (Sure is slow, e.g. building zip/unzip with gcc under DosBox. > Will try native and VMware/VirtualPC later..) I made a list of ways to speed up GCC, but I'm not sure how useful they would be in your situation. (e.g. -Os is between -O and -O2 in both compilation time and output speed) http://www.bttr-software.de/forum/board_entry.php?id=4619 In particular, you *could* always install native FreeDOS as dual boot and run that, but you may have to use a GParted liveCD to shrink your NTFS partition a bit to make a spare FAT partition. This may not be worth the effort (or slight risk, even), but it would definitely be faster (and DOSLFN works fine in FreeDOS). http://gparted.sourceforge.net/livecd.php http://rugxulo.googlepages.com
