I am wondering that if it it possible to run compile and run .c files without creating a project?Yes, but with limitations. Just try!
#include<stdio.h>
int main()
{
printf("Dr.Optix :D");
return 0;
}
Dr.Optix ,The default shortcut for compile current file is "Strg+Shift+F9" (easy to see if you open the "Build" menu).
For some reason, I cannot get it to work. It(F9) is just running previously compiled project. I have tried clean, clean workspace etc. I cannot get it to compile the currently open file that is not part of any project. Bear in mind though I do not want to delete or get rid of my open projects. I just want to be able to compile a file that is not part of any projetc, just for convenience.
