flags

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
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.
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.
ShadowedVariables	Warn when a variable, type declaration, or function is shadowed.
StaticRuntime	Perform a static link against the standard runtime libraries.
UndefinedIndentifiers	Warn if an undefined identifier is evaluated in an #if directive.
Unicode	Enable Unicode strings. If not specified, the default toolset behavior is used.
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)

Flags are often extended by external modules:

• D language flags

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

-- Create symbols for better debugging experience
flags { "Symbols" }
