问题
I installed MinGW on my Windows 8 laptop and tried to compile a C code file with
gcc test.c -o test.exe
the compiler gave no warnings or errors but it did not create test.exe
how do i get the compiler to create the file
test.c
My terminal session
An interesting observation:
When I deliberately introduce an error in the code and try to compile the compiler shows the error
Code with error
Compiler output
When I try compiling the same code using Command Prompt
This is what it shows
But the file does exist in the MinGW\bin directory
I moved the
test.c
file to
C:\
and started the command prompt in the
C:\MinGW\bin
directory
and here is what it outputs
Problem partially solved:
I disabled hybrid boot in windows 8 and restarted the computer. The compiler now works in Command Prompt but not in PowerShell.

Try to compile your code normally as
gcc test.c
If you get default output file a.exe,then go for
gcc test.c -o test.exe
回答2:
I would suggest you go through this compilation instruction :-
gcc -o test.exe test.c
I believe this code runs perfectly on your windows system.Please inform if it doesn't!

I know this is an old question, but I came across this after having this same issue and managed to solve it.
When I installed MinGW on my computer, I didn't add the MinGW bin directory to my PATH (<mingw install dir>\bin). I had written some code that referred to the GNU compiler binaries by their full path, and when I tried to compile something I experienced the same behavior you described.
So it seems like MinGW won't work properly unless it is added to your PATH. I think it's weird that gcc didn't complain about it though.

One possibility is Microsoft's use of VirtualStore.
This can cause problems with "missing" files with Cygwin. See for example, Cygwin sees a file that windows can't--I want to access this file from python and https://superuser.com/questions/400600/file-only-visible-to-cygwin-not-windows.
To verify whether this is the case, try doing a search of your entire hard drive for the file test.exe. Or try MinGW's ls rather than dir.
And since the OP "partially solved" the problem by moving to another directory, this could be the cause.
