Visual Stdio C + + compiler, linker common command line

The previous use of Visual Stdio is in an IDE environment. These two days of compiling GSL feel particularly inconvenient with the IDE environment, so it took a little time to learn how to use the Visual Stdio C + + compiler and connector at the command line.

I am personally familiar with GCC, so the various usages here have made the GCC analogy, which is also easy to remember.

Compiler CL

The C + + compiler in Visual Stdio is the same, called CL. The following table lists some basic command-line options.

CL	GCC	Description
/E	-E	Output preprocessing results
/fa	-S	Output assembly file
/za	-ansi	Prohibit language extension, these two are not equivalent
/dname	-dname	Defines a macro that is relative to the #define name that is added to the code
/dname=value	-dname=value	Defines a macro relative to the #define name value that is added to the code
/wall	-wall	Turn all warnings on.
/od	-o0	Disable optimization
/o1	-os	Optimized for the most space-saving goals
/o2	-o2	Optimized for the fastest possible speed
/idirecotry	-idirecotry	Specify header File Search path
/C	-C	Generate the target file. obj, not linked
/libpath:direcotry	-ldirecotry	Specifies the library file search path (msvc/libpath is a link option, before the first link option to specify the/LINK option to tell the compiler driver that subsequent options are passed to the linker)
/gr,/gr-	-frtti,-fno-rtti	Turn Rtti on or off
/link	-wl	Link the specified module or pass parameters to the linker
/ld	-shared	Compiling generated DLL files
/ldd		Compiling the DLL file (Debug version)
/md		MSVCRT.LIB links with Dynamic multithreaded version run-the-Library
/MDd		MSVCRTD.LIB link with Debug version of dynamic multithreaded version runtime
/mt		LIBCMT.LIB link to a static multithreaded version run-the-Library
/MTd		LIBCMTD.LIB link to the debug version of the static multithreaded version of the runtime library

In addition to these, there are a lot of command-line options, but for general use, these are enough.

Connector link

Corresponds to the LD in the GCC toolchain.

Link	LD	Description
/base:address		Specify the base address of the output file
/debug		Output Debug Mode version
/def:filename		Specifies the module definition file. Def
/defaultlib:library		Specify the default runtime
/dll	–relocateable	Generate DLL
/entry:symbol	–entry=symbol	Specifying the program entry
/export:symbol		Specify a symbol bit to export symbols
/heap		Specify the default heap size
/libpath:dir		Specify Link-Time library search Path
/map:mapfile	-map MAPFILE	Generate Link Map file
/nodefaultlib		Disable the default runtime library
/out:name	-O Name	Specify the output file name as name
/stack		Specify the default stack size
/subsystem		Specifying subsystems, common options are windows and console

Generate a static library. Lib

Lib can package a series of obj files into a static library. Lib. You can also combine several. lib into one. Lib. or combine several. obj and. Lib into one. Lib.

For example we have add.obj sub.obj div.lib These three files, we want to make them into a all.lib.
Then you can do this:

Lib Add.obj sub.obj div.lib/out: all.lib

If you want to merge these three files into one all.dll then we need a. def file. Which symbols are given to export.
It looks like this:

LIBRARY   all.dllexports   Add   Sub   div

Then execute the link command:

Link/subsystem:windows/dll/def:all.def/out: All.dll add.obj sub.obj div.lib
