HP DCE/9000 Application Development Tools for HP-UX 11i Release Note

HP DCE/9000 Version 1.8 Application Development Tools for HP-UX 11i Release Note

Developing DCE Applications with HP DCE/9000

This chapter provides information about developing, building, and debugging DCE

applications with HP DCE/9000.

NOTE The HP DCE applicationdevelopment software, including the IDL compiler, the

NIDL-to-IDL translator, DCE interface deﬁnition ﬁles and header ﬁles, the

International version of the DCE archive library, and the pthreads archive

library, may not be included in the HP-UX bundle that you installed. If you

intend to developHP DCE applications, you must explicitly install any software

that you require.

Building DCE Programs

NOTE Hewlett-Packard supports only the ANSI C compiler for building HP DCE

applications. Hewlett-Packard cannot provide support for problems with HP

DCE applications not compiled using ANSI C. This restriction also applies to

applications on HP-UX 10.x systems built using the HP-UX user-space threads

library (libcma).

When compiling and linking HP DCE applications, note the following:

• In order for the correct header ﬁle contents to be used, deﬁne _HPUX_SOURCE when

compiling your HP DCE application: -D_HPUX_SOURCE.

• In order for the correct header ﬁle contents to be used, deﬁne _REENTRANT and

_PTHREADS_DRAFT4 when compiling HP DCE programs as -D_REENTRANT and

-D_PTHREADS_DRAFT4 for the following reasons:

✓ To ensure that the threadsafe routines such as putc, putchar, getc, and get char are

used instead of the non-thread-safe macro versions deﬁned in stdio.h.

✓ To get deﬁnitions of new structures and to provide ANSI C prototype information for

the new reentrant interfaces.

• If you include <pthread.h>, you must do so before other header ﬁles in your C source ﬁle.

Also note that <pthread.h> deﬁnes _REENTRANT.
