The +inst_implicit_include option specifies that the compiler use a process similar to that
of the cfront source rule for locating template definition files. For the cfront based HP C++
compiler, if you are using default instantiation (that is, if you are not using a map file), you must
have a template definition file for each template declaration file, and these must have the same
file name prefix.
This restriction does not apply in HP aC++. Therefore, if your code was written for HP C++ and
you wish to follow this rule when compiling with HP aC++, you need to specify the
+inst_implicit_include option.
This option is strongly discouraged and the sources should be modified to conform to the standard.
Example:
aCC +inst_implicit_include prog.C
If prog.C includes a template declaration file named template.h, the compiler assumes a
template definition file name determined by the +inst_include_suffixes option.
See Chapter 5: “Using HP aC++ Templates” (page 132) for more information.
NOTE: This option is supported in C++ only and ignored in C-mode.
+inst_include_suffixes
+inst_include_suffixes "list"
The +inst_include_suffixes option specifies the file name extensions that the compiler uses
to locate template definition files. This option must be used with the +inst_implicit_include
option.
list is a set of space separated file extensions or suffixes, enclosed in quotes, that template
definition files can have.
The default extensions in order of precedence are:
• .c
• .C
• .cxx
• .CXX
• .cc
• .CC
• .cpp
User-specified extensions must begin with a dot and must not exceed four characters in total. Any
extension that does not follow these rules causes a warning and is ignored.
These restrictions do not apply in HP aC++. Therefore, if your code was written for HP C++ and
you wish to follow the cfront-based HP C++ template definition file naming conventions when
compiling with HP aC++, you need to specify the +inst_include_suffixes option.
The following example specifies that template definition files can have extensions of .c or .C:
+inst_include_suffixes ".c .C"
The +inst_include_suffixes option is equivalent to the HP C++ -ptS option.
See Chapter 5: “Using HP aC++ Templates” (page 132) for more information.
NOTE: This option is supported in C++ only and ignored in C-mode.
