Compiling and Linking in the OSS Environment
In addition to the C++ compiler pragmas recognized as command-line flags as described in
Chapter 13: Compiler Pragmas, the OSS c89 and c99 utilities have a -Wcplusplus flag that
affects both compilation and linking. This flag:
• Defines the __CPLUSPLUS feature-test macro to modify C header files for C++.
• Causes all specified files with names suffixed by .c to be compiled as C++ files.
If a linker is also involved or in other words if -c flag is not used, using the -Wcplusplus flag
causes the standard C++ libraries to be linked.
If the -Wcplusplus flag is not specified and none of the files operated upon by c89 or c99 has
a suffix of .C, .cpp, .cc, or .cxx, c89 or c99 compiles the source files only as C files; if the
-c flag is also omitted, c89 or c99 only links the C standard library.
Pragmas for the Standard C++ Library
You need to use the MAPINCLUDE and CPATHEQ pragmas to map UNIX or OSS pathnames to
Guardian file names. HP provides a CPATHEQ file for this purpose; the file is named SLMAP for
the Standard C++ Library. Like any CPATHEQ file, the SLMAP file maps OSS directory and file
names to the Guardian namespace ($volume.subvolume). Similarly, there is a TLHMAP file for
mapping names in Tools.h++ version 7.
The contents of a CPATHEQ file such as the
SLMAP file:
#ifndef __SLMAP
#define __SLMAP
#pragma mapinclude "rw/math.h" = "mathh"
#pragma mapinclude "rw/random.h" = "randomh"
#pragma mapinclude "rw/stddefs.h" = "stddefsh"
#pragma mapinclude "rw/stdgen.h" = "stdgenh"
#pragma mapinclude file "algorithm.cc" = "algoricc"
#pragma mapinclude file "bitset.cc" = "bitsetcc"
#pragma mapinclude file "complex.cc" = "complecc"
#pragma mapinclude file "deque.cc" = "dequecc"
#pragma mapinclude file "iterator.cc" = "iteratcc"
