NOTE

What Happens When You Compile and Link a Program

Compiler-Linker Interaction

Compiler-Linker Interaction

As described in “Looking “inside” a Compiler”, the compilers automatically call ld to create an executable file. To see how the compilers call ld, run the compiler with the -v(verbose) option. For example, compiling a C program in 32-bit mode produces the output below:

$ cc -Aa -v main.c func.c -lm

cc:CCOPTS is not set. main.c:

/opt/langtools/lbin/cpp.ansi main.c /var/tmp/ctmAAAa10102 \\ -D__hp9000s700 -D__hp9000s800 -D__hppa -D__hpux \\ -D__unix -D_PA_RISC1_1

cc:Entering Preprocessor.

/opt/ansic/lbin/ccom /var/tmp/ctmAAAa10102 main.o -O0 -Aa func.c:

/opt/langtools/lbin/cpp.ansi func.c /var/tmp/ctmAAAa10102 \\ -D__hp9000s700 -D__hp9000s800 -D__hppa -D__hpux \\ -D__unix -D_PA_RISC1_1

cc:Entering Preprocessor.

/opt/ansic/lbin/ccom /var/tmp/ctmAAAa10102 func.o -O0 -Aa

cc:LPATH is /usr/lib/pa1.1:/usr/lib:/opt/langtools/lib: /usr/ccs/bin/ld /opt/langtools/lib/crt0.o -u main main.o func.o -lm -lc

cc:Entering Link editor.

The next-to-last line in the above example is the command line the compiler used to invoke the 32-bit mode linker, /usr/ccs/bin/ld. In this command, ld combines a startup file (crt0.o) and the two object files created by the compiler (main.o and func.o). Also, ld searches the libm and libc libraries.

In 64-bit mode, the startup functions are handled by the dynamic loader, dld.sl. In most cases, the ld command line does not include crt0.o.

If you are linking any C++ object files to create an executable or a shared library, you must use the CC command to link. This ensures that c++patch executes and chains together your nonlocal static constructors and destructors. If you use ld, the library or executable may not work correctly and you may not get any error messages. For more information see the HP C++ Programmer's Guide.
