# Setup variables for the compiler

#
|
|
# COMPILTER_TYPE is the major type of compiler. Currently gcc and clang support
|
|
# automatic detetion. Other compiler types can be shoe-horned in, but require explicit
|
|
# setting of the compiler type. The compiler type can also be set explicitly if, say,
|
|
# you install gcc as clang...
|
|
#
|
|
# COMPILER_VERSION is a numeric constant equal to major * 10000 + minor * 100 + tiny. It
|
|
# too can be overriden on the command line. When testing it, be sure to make sure that you
|
|
# are limiting the test to a specific compiler. Testing against 30300 for gcc likely isn't
|
|
# what you wanted (since versions of gcc prior to 4.2 likely have no prayer of working).
|
|
#
|
|
# COMPILER_FEATURES will contain one or more of the following, based on compiler support
|
|
# for that feature: c++11 (supports full (or nearly full) C++11 programming environment).
|
|
#
|
|
# This file may be included multiple times, but only has effect the first time.
