Write the CUP in an ANSI C compliant C language. Compile the CUP's C source program to create an object file. Use the cc command for TP1/Client/W.

Table 3-2 shows the compiler options that must be set.

Table 3-2 Required compiler options (in HI-UX/WE2, HP-UX, and non-Windows environments)

TP1/Client version	Option	Meaning
TP1/Client/W	-Aa	Compile as ANSI C.

Example

C language UAP source programs:

• cupmain.c (main function)
• cupfnc1.c (internal function 1)
• cupfnc2.c (internal function 2)

Compile each source program as shown below.

TP1/Client/W

 
cc -c -I/usr/include -Aa cupmain.c
cc -c -I/usr/include -Aa cupfnc1.c
cc -c -I/usr/include -Aa cupfnc2.c
 

When the source programs contain dc_xxx_xxx_s functions that support a multi-thread environment, enter commands as shown below.

 
xlc_r -c cupmain.c
xlc_r -c cupfunc1.c
xlc_r -c cupfunc2.c
 

Executing the above cc commands produces the following object files:

• cupmain.o (object file containing the main function)
• cupfnc1.o (object file containing internal function 1)
• cupfnc2.o (object file containing internal function 2)

The CUP executable file is created by linking the files shown below. Use the cc command for TP1/Client/W.

• CUP object files (main function and internal functions)
• TP1/Client library

Example command lines for linking the above files are shown below.

Example

Creating the CUP executable file "example"

• Main function object file
  cupmain.o
  
• Internal function object files
  cupfncl.o and cupfnc2.o
  

Link the files as shown below.

TP1/Client/W

 
cc -o example cupmain.o cupfnc1.o cupfnc2.o
   -L/usr/lib -lclt
 

To create a CUP that supports a multi-thread environment, link the files by using the following command:

 
xlc_r -o example cupmain.o cupfnc1.o cupfnc2.o -L/usr/lib -lclt
 

The -L option can be omitted.
