Cl.exe is a 32-bit tool that controls Microsoft C and C ++ compilers and connectors. The compiler generates a Common Object File Format (coff) object (. OBJ) file. The linker generates an executable file (.exe) or a dynamic link library file (DLL ).
Cl.exe is used to compile source code files into OBJ object files that can be used by the linker. Cl.exe command line parameters are as follows:
CL (option ...) file... [Option | file]... [Lib...] [@ command-file] [/link-opt...]
