This section discusses the following topics:
| Major Components of the Compilation System |
The HP aC++ compiling system consists of the following components:
- aCC:
aCC is the driver. This is the only supported interface to HP aC++ and to
the linker for HP aC++ object files.
Location: /opt/aCC/bin/aCC
- ctcom:
ctcom is the compiler for version A.05.60. It compiles C++ source statements.
Preprocessing is incorporated into the compiler.
Location: /opt/aCC/lbin/ctcom
- ecom:
ecom is the compiler for version A.06.00. It compiles C++ source statements.
Preprocessing is incorporated into the compiler.
Location: /opt/aCC/lbin/ecom
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, parameter
number and name.
Location: /opt/aCC/bin/c++filt
- ld:
The linker links executables and builds shared libraries.
Location: /usr/ccs/bin/ld
HP aC++ Run-time 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++ Run-time 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)
- IOStream 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
Note: Some of the following runtime libraries are provided in both shared and
archive versions. Header files for these libraries are located at /opt/aCC/include and .

| Using the aCC Command |
|
To invoke the HP aC++ compiling system, use the aCC command at the shell prompt.
The aCC command invokes a driver program that runs the compiling system
according to the filenames and command line options that you specify.
Example:
$ aCC myprog.c

| Compiling and Executing a Simple Program |
Compiling a Simple Program
The best way to get started with HP aC++ is to write, compile, and execute a simple program,
like the following one:
#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 named getting_started.C:
$ a.out
Enter an integer: 7
14 is twice 7.

| Debugging Programs |
|
You can use the HP WDB Debugger to debug your C++ programs.
To do so, first compile your program with either the -g, the -g0, or the -g1 option.
Examples:
-
The -g0 option enables generation of debug information:
$ aCC -g0 program.C
-
The gdb command runs the HP WDB Debugger:
$ gdb a.out

| 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.
