Specifies build flags to modify the compiling or linking process.

flags { "flag_list" }

Parameters

flag_list is a list of string flag names; see below for a list of valid flags. The flag values are not case-sensitive. Flags that are not supported by a particular platform or toolset are ignored.

Flag	Description	Notes
ExcludeFromBuild	Exclude a source code file from the build, for the current configuration.
FatalCompileWarnings	Treat compiler warnings as errors.
FatalLinkWarnings	Treat linker warnings as errors.
FatalWarnings	Treat all warnings as errors; equivalent to FatalCompileWarnings, FatalLinkWarnings
LinkTimeOptimization	Enable link-time (i.e. whole program) optimizations.
Maps	Enable Generate Map File for Visual Studio
MFC	Enable support for Microsoft Foundation Classes.
MultiProcessorCompile	Enable Visual Studio to use multiple compiler processes when building.
No64BitChecks	Disable 64-bit portability warnings.
NoBufferSecurityCheck	Turn off stack protection checks.
NoCopyLocal	Prevent referenced assemblies from being copied to the target directory (C#)
NoFramePointer	Disable the generation of stack frame pointers.
NoImplicitLink	Disable Visual Studio's default behavior of automatically linking dependent projects.
NoImportLib	Prevent the generation of an import library for a Windows DLL.
NoIncrementalLink	Disable support for Visual Studio's incremental linking feature.
NoManifest	Prevent the generation of a manifest for Windows executables and shared libraries.
NoMinimalRebuild	Disable Visual Studio's minimal rebuild feature.	Visual Studio has deprecated this feature as of vs2015.
NoPCH	Disable precompiled header support. If not specified, the toolset default behavior will be used.
NoRuntimeChecks	Disable Visual Studio's default stack frame and uninitialized variable checks on debug builds.
OmitDefaultLibrary	Omit the specification of a runtime library in object files.
RelativeLinks	Forces the linker to use relative paths to libraries instead of absolute paths.
ShadowedVariables	Warn when a variable, type declaration, or function is shadowed.
StaticRuntime	Perform a static link against the standard runtime libraries.	Deprecated - use staticruntime "On" instead.
UndefinedIdentifiers	Warn if an undefined identifier is evaluated in an #if directive.
WinMain	Use WinMain() as entry point for Windows applications, rather than the default main().
WPF	Mark the project as using Windows Presentation Framework, rather than WinForms.
C++11	Pass the c++11 flag to the gcc/clang compilers (msvc ignores this currently)
C++14	Pass the c++14 flag to the gcc/clang compilers (msvc ignores this currently)
C90	Pass the c90 flag to the gcc/clang compilers (msvc ignores this currently)
C99	Pass the c99 flag to the gcc/clang compilers (msvc ignores this currently)

Applies To

Project and file configurations, though not all flags are yet supported for files across all exporters.

Availability

Unless otherwise noted, Premake 5.0 or later.

Examples

-- Enable link-time (i.e. whole program) optimizations.
