Building Executables

The -Bdynamic and -Bstatic options are still available, but their behavior is different. These options now refer to library inclusions to the executable rather than to the binding. Executable binding is set exclusively with the new -dy and -dn options in the Solaris 7 software. The -dy option is the default. It is required to create a dynamically linked executable. The -dn option is required to create a statically linked executable.

The -Bdynamic and -Bstatic options apply only when using the -dy option. -Bdynamic tells the link editor to include shared libraries, while -Bstatic tells it to include archive libraries. These options act as a toggle governing subsequent -l arguments until the next -Bdynamic or -Bstatic option is encountered.

The following examples show SunOS release 4 and Solaris 7 commands that can be used to create similar executables.

• sunos4.1% ld -Bstatic test.o -lx

  Uses libx.a and creates a static executable

• sunos5.x% cc -dn test.o -lx

  Uses libx.a and creates a static executable

• sunos4.1% ld -Bdynamic test.o -lx

  Uses libx.so and creates a dynamic executable

• sunos5.x% cc test.o -lx

  Uses libx.so and creates a dynamic executable

• sunos4.1% ld -Bdynamic test.o -Bstatic -lx

  Uses libx.a and creates a dynamic executable

• sunos5.x% cc test.o -Bstatic -lx

  Uses libx.a and creates a dynamic executable
