I see you are using backslashes for the command path. Are you running this in Windows CMD or a Cygwin bash?
You really should be working in bash, but it might work in CMD.

In CMD, try getting rid of the quotes ("). I think CMD will pass them to gcc, whereas bash would consume them.

Otherwise, what's your current directory? Can you cd to /cygdrive/c/virtuech/src/misc/cygwrap? And then run this:

gcc -Wall -O2 cygwrap.c -o mysimics/cygwrap.exe

Also, does the mysimics directory exist?

Thank you very much Ken...

Actually i am not manually doing this process.. I have to create a workspace for my simics simulation project.. I gave the below command in my cygwin bash shell in order to create a workspace....

"MEERAN@RABIYATHRAJA-HP ~$ /cygdrive/c/virtutech/bin/workspace-setup.bat mysimics

The above batch file do various task to create a workspace as below.

Setting up Simics workspace directory: mysimics
Created directory: C:\cygwin\home\MEERAN\mysimics
Created directory: C:\cygwin\home\MEERAN\mysimics\.workspace-properties
Created directory: C:\cygwin\home\MEERAN\mysimics\modules
Compiling 'cygwrap' wrapper
C:\cygwin\bin\gcc -Wall -O2 "/cygdrive/c/virtutech/src/misc/cygwrap/cygwrap.c" -
o "/home/MEERAN/mysimics/cygwrap.exe"
gcc: /cygdrive/c/virtutech/src/misc/cygwrap/cygwrap.c: No such file or directory

gcc: no input files

The last four lines where the workspace-setup.bat tries to compile the cygwrap is the place of war here. I have checked the path of cygwrap.c and it exists. And the compile operation is automated not manual...

Please help me...

Is the virtutech directory under C:\ or under C:\cygwin\?

Your .bat file is saying it's under C:\.

GCC is being executed, but it can't find the file, so that path must be wrong.
My first guess is that virtutech is really under C:\cygwin, not C:\.
If that's the case, just delete "/cygdrive/c".

gcc /virtutech/src/misc/cygwrap/cygwrap.c ...

Otherwise, verify that path. Something in it is wrong.


BTW, using a .bat file guarantees you are using the Windows CMD shell instead of bash.
That can work, but it's a shame. Bash is wonderful. I encourage you to use it.
