Re: Dynamic loader usage in RTEMS 5.1
Hi John, Have you studied the libdl tests yet? Code is in rtems.git/testsuites/libtests/dl* and build rules are in rtems.git/spec/build/testsuites/libtests/dl* You can probably get some hints from looking at the build log and the command that gets created. -Gedare On Fri, Jan 13, 2023 at 1:58 PM John Clemens wrote: > > I'm trying to understand how to build/link code to use the dynamic > loader in RTEMS v5.1.

Dynamic loader usage in RTEMS 5.1
I'm trying to understand how to build/link code to use the dynamic loader in RTEMS v5.1. I'm using https://docs.rtems.org/releases/rtems-5.1/user/exe/loader.html as a reference. My codebase has a core object and several components that will be loaded at boot time. I do the 2-pass linking step with the embedded global symbol table on my core object, and then run rtems-syms to generate "*-sym.o" objects for my runtime files (but do -not- send them through a second linking pass). Now I have a core object and several "fooX.o" and "fooX-sym.o" files.. what do I do from here? Are the fooX-sym.o files supposed to be linked into the core object somehow? I'm sure I'm missing an obvious step. Any pointers? Thanks! john.c -- John Clemens ___ users mailing list users@rtems.org http://lists.rtems.org/mailman/listinfo/users
