Run time libraries such as the C RTL are associated with the image at
link time. While you may be able to do tricks with logicals to use a
different file, the association is still static since symbols are
resolved at link time and the image will just branch to specific
addresses where the routine is expected to reside within the shareable
image.
This is qwuite diffferent from lib$find_image_symbol where nothing
happens at link time and the finding and resolving of symbols within
some image file is done truly at run time.
No and no.
Static linking means that the code of the library is in the
executable EXE.
Dynamic linking means that the code of the library is in a
shareable EXE.
Static linking is a concept practically unknown on VMS.
I agree with you up until this point.
I have many applications that link against OLB libraries. The code from the library gets copied into the executable. My build procedures rarely link against OBJ files. Much better to have them in a library.
