Hello – I am on a Windows 10,64-bit machine. I installed the MinGW basic installation. When I tried to compile my first hello world program from the command line. #include <stdio.h> int main() { printf("Hello, This is cool! \n"); return 0; } D:\java\gcc HelloWorld.c -o D:\java\Hello.exe no executable. I tried it first with -o Hello.exe, same result The compiler acts like it’s doing something, no errors but no output. So I ran it with the -v switch and got (among other things) d:/mingw/bin/../lib/gcc/mingw32/9.2.0/../../../../mingw32/bin/ld.exe: cannot open output file Hello.exe: Permission denied I am running the command shell as administrator (full control rights) Not sure what the problem is – been searching around the web for a bit.
