Have a look at:

  http://seqaxp.bio.caltech.edu/pub/SOFTWARE/MAKE_OPT_FROM_OLB.COM

Which I use like this to build shared images from .olb files (assuming it 
doesn't also need further touch up work to the .olb to handle, for instance,
global symbols.)

$ write sys$output "Starting to build XPM shared library"
$ @MAKE_OPT_FROM_OLB xpm.olb X11  XPMDATATYPES,XPMCOLORKEYS
$ link/share=[]xpm_shr.exe xpm.opt/opt
$ write sys$output "Moving XPM_SHR to SYS$SHARE"
$ copy xpm_shr.exe sys$share
$ set file/prot=w:re sys$share:xpm_shr.exe

The make_opt_from_olb procedure crates likes like:

SYMBOL_VECTOR = (XPMFREEATTRIBUTES=PROCEDURE)

but it cannot find out about global variables.  You have to figure our 
where those are required by hand and write up that part of the .opt file. 
Here's a more complicated example used to build xforms that does some of 
this.

$ write sys$output "Starting to build XFORMS shared library"
$ create xpm2.opt
$ open/append ofil xpm2.opt
$ write ofil "sys$share:xpm_shr.exe/share"
$ search/out=ofil/match=nor global_psects.opt "this string is not in the file"
$ close ofil
$ @MAKE_OPT_FROM_OLB xforms.olb GL,X11 "" xpm2.opt

Where global_psects.opt has a bunch of lines in it like:

SYMBOL_VECTOR = (FL_CUR_COLOR=PSECT)

corresponding to global variables.
