Chandan, When I try to compile UML/WIN32 according to the instruction in page http://toad.net/~chandan/umlwin32/download.html, but I get the following error message. Did you have this problem ? After I checked the make file and I found it is because a command "rev" cannot be found. $ make linux ARCH=um gcc -D__WIN32__ -D__KERNEL__ -I/usr/src/umlwin32/include -Wall -Wstrict-prototyp es -Wno-trigraphs -O2 -fno-strict-aliasing -fno-common -g -U__i386__ -Ui386 -D UM_FASTCALL -D__arch_um__ -DSUBARCH=\"i386\" -DNESTING=0 -D_LARGEFILE64_SOURCE - I/usr/src/umlwin32/arch/um/include -Derrno=kernel_errno -DKBUILD_BASENAME=main -c -o init/main.o init/main.c init/main.c: In function `calibrate_delay': init/main.c:358: warning: unused variable `lps_precision' init/main.c:357: warning: unused variable `loopbit' init/main.c:357: warning: unused variable `ticks' init/main.c: In function `start_kernel': init/main.c:580: warning: assignment from incompatible pointer type . scripts/mkversion > .tmpversion gcc -D__WIN32__ -D__KERNEL__ -I/usr/src/umlwin32/include -Wall -Wstrict-prototyp es -Wno-trigraphs -O2 -fno-strict-aliasing -fno-common -g -U__i386__ -Ui386 -D UM_FASTCALL -D__arch_um__ -DSUBARCH=\"i386\" -DNESTING=0 -D_LARGEFILE64_SOURCE - I/usr/src/umlwin32/arch/um/include -Derrno=kernel_errno -DUTS_MACHINE='"um"' -D KBUILD_BASENAME=version -c -o init/version.o init/version.c make CFLAGS="-D__WIN32__ -D__KERNEL__ -I/usr/src/umlwin32/include -Wall -Wstrict -prototypes -Wno-trigraphs -O2 -fno-strict-aliasing -fno-common -g -U__i386__ -Ui386 -DUM_FASTCALL -D__arch_um__ -DSUBARCH=\"i386\" -DNESTING=0 -D_LARGEFILE64 _SOURCE -I/usr/src/umlwin32/arch/um/include -Derrno=kernel_errno " -C kernel make[1]: Entering directory `/usr/src/umlwin32/kernel' make all_targets make[2]: rev: Command not found make[2]: Entering directory `/usr/src/umlwin32/kernel' rm -f kernel.o ld -r -o kernel.o ld: no input files make[2]: *** [kernel.o] Error 1 make[2]: Leaving directory `/usr/src/umlwin32/kernel' make[1]: *** [first_rule] Error 2 make[1]: Leaving directory `/usr/src/umlwin32/kernel' make: *** [_dir_kernel] Error 2 Roger Chandan Kudige <ch...@to...> wrote: >The intent is to make UML/Win32, a native linux environment under windows >without using emulators or virtual machines.
