  Attached below are instructions for making shared libraries
  on Sun OS4. Does anyone know what the equivalent instructions
  are on ULTRIX and OSF/1 using gcc?

  E-mail but feel free to post.

  Thanks,

  Emmett
 

   1.  Make for a subroutine/function:

      cc -PIC -c filename.c -o filename.o


   2.  Make the shared library (libtest.so.1.1)

      ld -o libtest.so file1.o file2.o file3.o -assert pure-text

      (Now rename libtest.so to libtest.so.1.1)

   3.  Linking the main program (make sure that libtest is in the LD_LIBRARY_PATH
   during runtime): 

      cc main.o -o a.out -L/yourlibdir -Bdynamic -ltest

First, the simple one:

	On ULTRIX, you can't produce or use shared libraries.
	End of story.

Second, the other simple one:

	On DEC OSF/1, you don't do anything special with GCC to
	create shared libraries. Read the section 3 of the Programmers
	Guide. Basically, you just create a normal library with all
	the normal flags you're used to. If you later decide that
	the library is to your liking:


		libfoo.a


	Then:

		ld -shared -no_archive -all libfoo.a -none -lc -o libfoo.so

	This example assumes that your shared library in turn is dependent
	only on the C library. If other libraries are needed in turn (say
	the math library), these go into the section after "-none".
