CL and Link commands

You can compile and link c/c++ code via cl and link
Generic Examples
cl /Od /D /D_DEBUG /Yd /Zi /EHsc /MTd /GS /Fo"build/" /W3 /nologo /c

Important note for above example

/c - compile only. Without this, it will tries to link as well
/I - add 1 include folder
/D - add 1 user define marco
/D_DEBUG - add debug information


Important note for above example

/DEBUG - link with debug information
>/OUT - output name and location
/LIBPATH - add 1 library path

Sample Usage

cl /Od /D /D_DEBUG /Yd /Zi /EHsc /MTd /GS /Fo"build/" /W3 /nologo /c
/I "include" /I "test\include" /D "MY_MARCO1" /D "MY_MARCO2" src\*.c src\*.cpp

link /DEBUG /OUT:"output\my.dll" /INCREMENTAL:NO /NOLOGO
/LIBPATH:"lib" /LIBPATH:"my\lib" /DLL /SUBSYSTEM:WINDOWS /OPT:REF /OPT:ICF /IMPLIB:"output\my.lib" /MACHINE:X86 first.lib second.lib

Visual C++ Linker Options
Linker Options

LINK is a tool that links Common Object File Format (COFF) object files and libraries to create a executable (.exe) file or dynamic-link library (DLL).

The table below is a comprehensive list of options for LINK.exe. This section also includes information on:

Linker options specified on the command line are not case sensitive: /base and /BASE mean the same thing.

You can specify some linker options via the comment pragma.

/CLRUNMANAGEDCODECHECK specifies whether the linker will apply the SuppressUnmanagedCodeSecurity attribute to linker-generated PInvoke stubs that call from managed code into native DLLs.
