Top Forums Programming update executable file Post 8964 by anent on Friday 19th of October 2001 03:40:52 PM

Thanks rwb & MacMonster,
I want to clear out a little bit.
I have my executable file ready. and if i make changes in the source code and again if i compile the code. it takes the same time for compiling.

what i need is : the already available executable should be updated without overwriting with the executable created with the same name.

ie.,
gcc test.c -o myprog
o/p : myprog - executable file
if i run it again, - after small modification
gcc test.c -o myprog
o/p : myprog - exe file - but same compiling time.
but the modification made to the source is a little bit.

Idea:
Case 1; If i create some modules of C source codes.and if i modify the code to any one of the module.
How can i reduce my runtime of the exe file creation.
Case 2; If it is a single module.. then.

any inputs are appreciated.

elksemu

elksemu(1)						      General Commands Manual							elksemu(1)

NAME

       elksemu - Embedded Linux Kernel Subset emulator

SYNOPSIS

       /lib/elksemu program [arguments]

DESCRIPTION

       Elksemu is a program that allows 8086 ELKS programs to be run under Linux-i386. These programs can be compiled using the bcc(1) C compiler.

       It  is not usual to invoke /lib/elksemu directly, either the simple patch or kernel module distributed with it will cause the kernel to run
       /lib/elksemu with the correct arguments whenever the user tries to execute an ELKS executable directly.

OPTIONS

       There are no flag options to elksemu, the first argument is the name of the program to run the rest are arguments that are  passed  to  the
       Elks program.

       The  elksemu  program is normally installed suid-root and in this event it is able to run execute only (chmod 111) elks executables and act
       correctly on the suid permission bits on those executable. This may be considered a  security  hazard  so  elksemu  does  not  have  to	be
       installed suid-root.

SEE ALSO

       bcc(1), as86(1), ld86(1)

BUGS

       Elksemu is incomplete.

       The program may still have security bugs!
