1# $FreeBSD$ 2 3# Setup variables for the compiler 4# 5# COMPILER_TYPE is the major type of compiler. Currently gcc and clang support 6# automatic detection. Other compiler types can be shoe-horned in, but require 7# explicit setting of the compiler type. The compiler type can also be set 8# explicitly if, say, you install gcc as clang... 9# 10# COMPILER_VERSION is a numeric constant equal to: 11# major * 10000 + minor * 100 + tiny 12# It too can be overriden on the command line. When testing it, be sure to 13# make sure that you are limiting the test to a specific compiler. Testing 14# against 30300 for gcc likely isn't what you wanted (since versions of gcc 15# prior to 4.2 likely have no prayer of working). 16# 17# COMPILER_FEATURES will contain one or more of the following, based on 18# compiler support for that feature: 19# 20# - c++11 : supports full (or nearly full) C++11 programming environment. 21# 22# This file may be included multiple times, but only has effect the first time. 23# 24 25.if !target(__<bsd.compiler.mk>__) 26__<bsd.compiler.mk>__: 27 28.if ${MACHINE} == "common" 29# common is a pseudo machine for architecture independent 30# generated files - thus there is no compiler. 31COMPILER_TYPE= none 32COMPILER_VERSION= 0 33.elif !defined(COMPILER_TYPE) || !defined(COMPILER_VERSION) 34_v!= ${CC} --version 2>/dev/null || echo 0.0.0 35 36.if !defined(COMPILER_TYPE) 37. if ${CC:T:M*gcc*} 38COMPILER_TYPE:= gcc 39. elif ${CC:T:M*clang*} 40COMPILER_TYPE:= clang 41. elif ${_v:Mgcc} 42COMPILER_TYPE:= gcc 43. elif ${_v:M\(GCC\)} 44COMPILER_TYPE:= gcc 45. elif ${_v:Mclang} 46COMPILER_TYPE:= clang 47. else 48.error Unable to determine compiler type for ${CC}.
