# \section{Building C and C++ code}
#
# \OMake{} provides extensive support for building C and C++ programs. In order to use the functions
# defined in this section, you need to make sure the line
# \begin{verbatim}
# open build/C
# \end{verbatim}
# is present in your \verb+OMakeroot+ file.
#
# \subsection{Autoconfiguration variables}
# These variables will get defined based on the ``autoconf-style'' \verb+static.+ tests executed
# when you run \OMake{} for the first time. You can use them to configure your project accordingly,
# and you should not redefine them.
#
# You can use the \verb+--configure+ command line option (Section~\ref{option:--configure}) to force
# re-execution of all the tests.
#
# A different set of autoconfiguration tests is performed depending on the build environment
# involved --- one set of tests would be performed in a \verb+Win32+ environment, and another ---
# in a Unix-like environment (including Linux, OS X and Cygwin).
#
# \subsubsection{Unix-like systems}
# \varlabel{GCC_FOUND}{GCC\_FOUND} A boolean flag specifying whether the \verb+gcc+ binary was found in your path.
# \varlabel{GXX_FOUND}{GXX\_FOUND} A boolean flag specifying whether the \verb.g++. binary was found in your path.
# 
# \subsubsection{Win32}
# \varlabel{CL_FOUND}{CL\_FOUND} A boolean flag specifying whether the \verb+cl+ binary was found in your path.
# \varlabel{LIB_FOUND}{LIB\_FOUND} A boolean flag specifying whether the \verb+lib+ binary was found in your path.
#
# \subsection{C and C++ configuration variables}
#
# The following variables can be redefined in your project.
#
# \var{CC} The name of the C compiler (on \verb+Unix+ it defaults to \verb+gcc+ when \verb+gcc+ is present and
#   to \verb+cc+ otherwise; on \verb+Win32+ defaults to \verb+cl /nologo+).
# \var{CXX} The name of the C++ compiler (on \verb+Unix+ it defaults to \verb+gcc+ when \verb+gcc+ is present
#   and to \verb+c+++ otherwise; on \verb+Win32+ defaults to \verb+cl /nologo+).
# \var{CPP} The name of the C preprocessor (defaults to \verb+cpp+ on \verb+Unix+, and \verb+cl /E+ on \verb+Win32+).
# \var{CFLAGS} Compilation flags to pass to the C compiler (default empty on \verb+Unix+, and \verb+/DWIN32+
#   on \verb+Win32+).
# \var{CXXFLAGS} Compilation flags to pass to the C++ compiler (default empty on \verb+Unix+, and \verb+/DWIN32+
#   on \verb+Win32+).
# \var{INCLUDES} Additional directories that specify the search path to the C and C++ compilers (default is \verb+.+).
#   The directories are passed to the C and C++ compilers with the \verb+-I+ option.
#   The include path with \verb+-I+ prefixes is defined in the \verb+PREFIXED_INCLUDES+ variable.
# \var{LIBS} Additional libraries needed when building a program (default is empty).
# \var{CCOUT} The option to use for specifying the output file in C and C++ compilers
#     (defaults to \verb+-o+ on \verb+Unix+ and \verb+/Fo+ on \verb+Win32+).
# \var{AS} The name of the assembler (defaults to \verb+as+ on \verb+Unix+, and \verb+ml+ on \verb+Win32+).
# \var{ASFLAGS} Flags to pass to the assembler (default is empty on \verb+Unix+, and \verb+/c /coff+
#     on \verb+Win32+).
# \var{ASOUT} The option string that specifies the output file for \verb+AS+ (defaults to \verb+-o+
#     on \verb+Unix+ and \verb+/Fo+ on \verb+Win32+).
# \var{AR} The name of the program to create static libraries (defaults to \verb+ar cq+ on \verb+Unix+,
#     and \verb+lib+ on \verb+Win32+).
# \var{LD} The name of the linker (defaults to \verb+ld+ on \verb+Unix+, and \verb+cl+ on \verb+Win32+).
# \var{LDFLAGS} Options to pass to the linker (default is empty).
# \varlabel{LDFLAGS_DLL}{LDFLAGS\_DLL} Options to pass to the linker when compiling a shared library (defaults to \verb+-shared+ on \verb+Unix+ and \verb+/DLL+ on \verb+Win32+).
# \var{LDOUT} The option to use for specifying the output file in C and C++ linkers
#     (defaults to \verb+-o+ on \verb+Unix+ and \verb+/Fe+ on \verb+Win32+).
# \var{YACC} The name of the \verb+yacc+ parser generator (default is \verb+yacc+ on \verb+Unix+, empty on \verb+Win32+).
# \var{LEX} The name of the \verb+lex+ lexer generator (default is \verb+lex+ on \verb+Unix+, empty on \verb+Win32+).

# Make sure generated files are built before scanning

# \begin{doc}

# Because the C scanners do not normally know anything about generated source files (such as
# generated header files), these files may need to be created before running the scanner.

# if \verb+config.h+ and \verb+inputs.h+ are both generated files, specify:
# \begin{verbatim}
# CGeneratedFiles(config.h inputs.h)
# \end{verbatim}
#
# The \verb+CGeneratedFiles+ function is \emph{global} --- its arguments will be generated
# before any C files anywhere in the project are scanned for dependencies. The
# \verb+LocalCGeneratedFiles+ function follows the normal scoping rules of OMake.
