When using gcc command,it presents :NO such file or directory

I recommend you go about it with something similar to this ...

>type stub.c
void main() {}

>C:\ti\ccsv6\tools\compiler\gcc-arm-none-eabi-4_8-2014q3\bin\gccvar.bat

>arm-none-eabi-gcc stub.c -M
stub.o: stub.c

>arm-none-eabi-gcc stub.c -o stub -lc -lgcc -lnosys

The command on line 1 shows you the contents of stub.c  The command on line 4 shows you how to invoke a batch file that changes the path, but only for the current command window.  The command on line 6 is what you attempted to do.  The results are dumped to the screen, instead of being captured in a file.  The command on line 9 shows you how to build and link all in one command line.  The 3 -l options tell the compiler to use those standard libraries in the link. 

Thanks and regards,
