.IP CFile
Builds a C source file given a lex (.l) or yacc (.y) input file.
-The hard-coded suffix .c is
-automatically added to the target
+The suffix specified by the $CFILESUFFIX construction variable
+(.c by default)
+is automatically added to the target
if it is not already present. Example:
.ES
env.CFile(target = 'foo.c', source = 'foo.l') # builds foo.c
env.CFile(target = 'bar', source = 'bar.y') # builds bar.c
.EE
+
+.IP CXXFile
+Builds a C++ source file given a lex (.ll) or yacc (.yy) input file.
+The suffix specified by the $CXXFILESUFFIX construction variable
+(.cc by default)
+is automatically added to the target
+if it is not already present. Example:
+
+.ES
+env.CXXFile(target = 'foo.cc', source = 'foo.ll') # builds foo.cc
+env.CXXFile(target = 'bar', source = 'bar.yy') # builds bar.cc
+.EE
.LP
C/C++ source files are automatically scanned for dependencies by
.B scons
.IP BUILDERS
A list of the available builders.
-[CFile, Object, Program, Library] by default.
+[CFile, CXXFile, Object, Program, Library] by default.
.IP CC
The C compiler.
.IP CFILESUFFIX
The suffix for C source files.
This is used by the internal CFile builder
-when generating destination files from Lex (.l) or YACC (.y)
-input files.
+when generating C files from Lex (.l) or YACC (.y) input files.
The default suffix, of course, is
.IR .c .
.IP CXX
The C++ compiler.
+.IP CXXFILESUFFIX
+The suffix for C++ source files.
+This is used by the internal CXXFile builder
+when generating C++ files from Lex (.ll) or YACC (.yy) input files.
+The default suffix is
+.IR .cc .
+
.IP CXXFLAGS
General options that are passed to the C++ compiler.
- Add a configurable CFILESUFFIX for the Builder of .l and .y files
into C files.
+ - Add a CXXFile Builder that turns .ll and .yy files into .cc files
+ (configurable via a CXXFILESUFFIX construction variable).
