Programming a BEA Tuxedo Application Using COBOL

Building Clients

To build an executable client, compile your application with the BEA Tuxedo system libraries and all other referenced files using the buildclient(1) command. Include the -C option to indicate that you are compiling a COBOL program. Use the following syntax for the buildclient command.

buildclient -C filename.cbl -o filename -f filenames -l filenames

The following table describes the options to the buildclient command.

buildclient Options

This Option or Argument . . .
Allows You to Specify . . .

filename.cbl

The COBOL application to be compiled.

-o filename

The executable output file. The default name for the output file is a.out.

-f filenames

A list of files that are to be link edited before the BEA Tuxedo system libraries are link edited. You can specify -f more than once on the command line, and you can include multiple filenames for each occurrence of -f. If you specify a COBOL program file (file.cbl), it is compiled before it is linked. You can specify other object files (file.o) separately, or in groups in an archive file (file.a).

-l filenames

A list of files that are to be link edited after the BEA Tuxedo system libraries are link edited. You can specify -l more than once on the command line, and you can include multiple filenames for each occurrence of -l. If you specify a COBOL program file (file.cbl), it is compiled before it is linked. You can specify other object files (file.o) separately, or in groups in an archive file (file.a).

-r

The resource manager access libraries that should be link edited with the executable server. The application administrator is responsible for predefining all valid resource manager information in the $TUXDIR/updataobj/RM file using the buildtms(1) command. Only one resource manager can be specified. Refer to Setting Up a BEA Tuxedo Application for more information.

This Option or Argument . . .	Allows You to Specify . . .
filename.cbl	The COBOL application to be compiled.
-o filename	The executable output file. The default name for the output file is a.out.
-f filenames	A list of files that are to be link edited before the BEA Tuxedo system libraries are link edited. You can specify -f more than once on the command line, and you can include multiple filenames for each occurrence of -f. If you specify a COBOL program file (file.cbl), it is compiled before it is linked. You can specify other object files (file.o) separately, or in groups in an archive file (file.a).
-l filenames	A list of files that are to be link edited after the BEA Tuxedo system libraries are link edited. You can specify -l more than once on the command line, and you can include multiple filenames for each occurrence of -l. If you specify a COBOL program file (file.cbl), it is compiled before it is linked. You can specify other object files (file.o) separately, or in groups in an archive file (file.a).
-r	The resource manager access libraries that should be link edited with the executable server. The application administrator is responsible for predefining all valid resource manager information in the $TUXDIR/updataobj/RM file using the buildtms(1) command. Only one resource manager can be specified. Refer to Setting Up a BEA Tuxedo Application for more information.

Note: The BEA Tuxedo libraries are linked in automatically; you do not need to specify any BEA Tuxedo libraries on the command line.

The order in which you specify the library files to be link edited is significant: it depends on the order in which functions are called in the code, and which libraries contain references to those functions.

By default, the buildclient command invokes the UNIX cc command. You can set the ALTCC and ALTCFLAGS environment variables to specify an alternative compile command, and to set flags for the compile and link-edit phases, respectively. By default, ALTCC is set to cobcc. For more information, refer to Setting Environment Variables.

Note: On a Windows NT system, the ALTCC and ALTCFLAGS environment variables are not applicable; setting them will produce unexpected results. You must compile your application by first using a COBOL compiler, and then passing the resulting object file to the buildclient command. For example:

buildclient -C -o audit -f audit.o

The following example command line compiles a COBOL program called audit.cbl and generates an executable file named audit.

buildclient -C -o audit -f audit.cbl
