# compute directories for invoking GCC
|
|
#
|
|
# The gcc toolset can be user-configured using the following
|
|
# variables:
|
|
#
|
|
# GCC_ROOT_DIRECTORY
|
|
# The directory in which GCC was installed. Defaults to
|
|
# unset. Usually, there is no need to set this variable at
|
|
# all. However, if G++ is not in the path it is usually
|
|
# sufficient to configure this one variable. More fine-grained
|
|
# configuration is available by setting the following:
|
|
#
|
|
# GCC_BIN_DIRECTORY
|
|
# the directory prefix used to find the gcc executables. Defaults to
|
|
# $(GCC_ROOT_DIRECTORY)/bin/, or "" if GCC_ROOT_DIRECTORY is
|
|
# not set.
|
|
#
|
|
# GCC_INCLUDE_DIRECTORY
|
|
# the directory in which to find system includes. Defaults to
|
|
# $(GCC_ROOT_DIRECTORY)/include.
|
|
#
|
|
# GCC_STDLIB_DIRECTORY
|
|
# the directory in which to find the standard library
|
|
# objects associated with this build of gcc. Defaults to
|
|
# $(GCC_ROOT_DIRECTORY)/lib.
|
|
#
|
|
# GXX
|
|
# The name by which g++ is invoked. You can also use this in
|
|
# lieu of setting the <cxxflags> property to force options such
|
|
# as "-V3.0.4" into the g++ command line: "-sGXX=g++ -V3.0.4".
|
|
#
|

# Similar to GXX, the name by which gcc is invoked for "C"
|
|
# language targets.
