Building DCE Programs
Header Files
In addition to the standard POSIX libraries and HP C/XL functions, you
may have to include the DCE header files, which can be found in the
/usr/include/dce directory. If your C applications use Try/Catch for
exception handling, you should include the following statement in the C
programs:
#include <dce/pthread_exc.h>
There are no MPE/iX equivalent libraries for /usr/lib/libbb.a or
/usr/lib/libc_r.a. The reentrant functions that are defined in MPE/iX
and the thread-safe wrapper functions are in /usr/lib/libdce.a.
MPE/iX does not have the file strings.h. The HP-UX strings.h includes
string.h, sys/stdsyms.h and some definitions that are strictly for C++
and HP-UX.
Compiler Flags
When compiling DCE applications using ANSI C under the MPE CI, set the
following compiler switches:
-D_POSIX_SOURCE -D_MPEXL_SOURCE -D_SOCKET_SOURCE -D_REENTRANT -Aa
When compiling under the MPE POSIX shell, you need the above flags except
for the -Aa optoin. If -Aa is set, /bin/c89 displays a large amount of
error messages (by definiton, the POSIX environment always uses the ANSI
C compiler).
Unresolved Externals
When porting applications from a unix environment to MPE/iX, you may
receive unresolved external errors during a compile, link, or run phase.
It is likely that the unresolved externals are not part of the POSIX.1
standard. To find out if a function is defined in the POSIX environment,
look at the manpage for that function on a UNIX system. At the bottom of
the manpage, there is a section titled STANDARD CONFORMANCE, which lists
the function name and the standard it conforms to. If the manpage does
not have POSIX.1 listed as one of the standards then that function is not
part of the MPE/iX Posix Environment. To get around this porting issue,
you may have to write a routine to emulate the functionality for the
unresolved external.
MPE/iX Makefile Example
