Components of the Compilation System

The HP aC++ compiling system consists of the following components:

aCC: The aCC driver is the only supported interface to HP aC++ and to the linker for HP aC++ object files.
cc: cc is the HP-UX C compiler.
c89: c89 is the HP-UX ANSI-conforming C89 compiler.
c99: c99 is the HP-UX ANSI-conforming C99 compiler.
ecom: The ecom compiler (for A.06.*) compiles the C++ source statements. Preprocessing is incorporated into the compiler.
ctcom: The ctcom compiler (for A.05.*) compiles the C++ source statements. Preprocessing is incorporated into the compiler.

The other HP aC++ executable files are:

C++filt: C++filt is the name demangler. It implements the name demangling algorithm which encodes function name, class name, and parameter number and name.
ld: ld is the linker. It links executables and builds shared libraries.

HP aC++ Runtime Libraries and Header Files:

Standard C++ Library
       /usr/lib/hpux32/libstd.so (32-bit shared version)
       /usr/lib/hpux32/libstd.a  (32-bit archive version)
       /usr/lib/hpux64/libstd.so (64-bit shared version)
       /usr/lib/hpux64/libstd.a  (64-bit archive version)

HP aC++ Runtime Support Library
       /usr/lib/hpux##/libCsup.so       
       /usr/lib/hpux##/libstd.so and libstd_v2.so
       /usr/lib/hpux##/libstd_v2.so and librwtool_v2.so 
       /usr/lib/hpux##/libstream.so
       Libraries in /usr/include/hpux##

       (where ## is 32 or 64 provided as part of the HP-UX core system)

Standard C++ Library
       /usr/lib/hpux32/libstream.so (32-bit shared version)
       /usr/lib/hpux32/libstream.a  (32-bit archive version)
       /usr/lib/hpux64/libstream.so (64-bit shared version)
       /usr/lib/hpux64/libstream.a  (64-bit archive version)

       Header files for these libraries are located at /opt/aCC/include/.

Using the aCC Command

To invoke the HP aC++ compiling system, use the aCC command at the shell prompt. TheaCC command invokes a driver program that runs the compiling system according to the filenames and command line options that you specify.

Compiling a Simple Program

The best way to get started with HP aC++ is to write, compile, and execute a simple program, as shown in the following example:

#include <iostream.h>
int main()
{
      int x,y;
      cout << “Enter an integer: “;
      cin >> x;
      y = x * 2;
     cout << “\n” << y <<“ is twice “ << x <<“.\n”;
}

If this program is in the file getting_started.C, compiling and linking the program with the aCC command produces an executable file named a.out:

$ aCC getting_started.C

Executing the Program

To run this executable file, just enter the name of the file. The following summarizes this process with the file getting_started.C:

$ a.out

Enter an integer: 7

14 is twice 7.

Debugging Programs

You can use programming and debugging aides.

HP Code Advisor

HP Code Advisor is a code checking tool that can be used to detect programming errors in C/C++ source code. Use "/opt/cadvise/bin/cadvise" to invoke the tool. A brief description is available with the -help option.

$ /opt/cadvise/bin/cadvise -help

Additional information is available at: http://www.hp.com/go/cadvise/.

HP WDB Debugger

You can also use the HP WDB debugger to debug your C++ programs after compiling your program with either the -g, the -g0, or the -g1 option.

Example:

The -g0 option enables generation of debug information:

$ aCC -g0 program.C

The gdb command runs the HP WDB debugger:

$ gdb a.out

For more information on the HP WDB debugger, refer to “Debugging Options”.

Accessing Online Example Source Files

Online example source files are located in the directory /opt/aCC/contrib/Examples/RogueWave. These include examples for the Standard C++ Library and for the Tools.h++ Library.
