Usage Guidelines
TDS version of the TNS/R native C/C++ cross compiler produces object code that runs
only on NonStop S-series system in either the Guardian or the OSS environment.
Source code that is compilable by the TNS/R native C and C++ compilers running on
NonStop S-series system is also compilable by the native PC cross compiler, except
for these differences:
•
The default target environment for the PC cross compiler is the Guardian
environment. To produce programs that run in the OSS environment, specify the
-Wsystype=oss flag to the c89 utility.
•
The native C PC cross compiler supports embedded SQL. When you enable SQL,
HP C passes the SQL options you choose to cfe so that embedded SQL
statements are compilable. Additional options are required on the PC as well.
•
To use the C/C++ cross compiler, the source files must reside in the PC
namespace. Because the cross compiler runs on the PC, the compiler cannot see
files located on NonStop server nodes. Therefore, you must transfer your source
files from the server to the PC using file transfer protocol (FTP).
When your source files are on the PC, they can be distributed anywhere in the PC
namespace. Likewise, any files that are output from the PC cross compilers can be
distributed anywhere in the PC namespace.
•
PC source files with #include path names use the backslash (\) separator.
These path names are correctly interpreted by the PC cross compilers. However,
PC path names cannot be used by the native compilers that run on NonStop
servers.
•
The PC cross compiler interprets the slash character (\) in #include path names
as a backslash (\). Therefore, OSS source files with directory names can map
automatically to the PC namespace.
•
The PC cross compiler handles source-file name suffixes in the same manner as
c89. Source-file names must be identified with the .suffix format just as are
OSS file names. Guardian, however, does not allow the .suffix file-name
format. Therefore, Guardian file names drop the period, and the suffix becomes the
last character of the file name. However, the.suffix format must be used when
