Help with RTEMS C User’s Guide

[Tanu Hari Dixit]

Hello Devs,

I have been trying to setup a makefile so as to execute the various code
snippets given in the C User's guide for RTEMS (https://docs.rtems.org/doc-
current/share/rtems/html/c_user/index.html#SEC_Contents) and have failed
miserably. Can you please help me with this?

I have made a file with the first example of printing object names (
https://docs.rtems.org/doc-current/share/rtems/html/c_
user/Key-Concepts-Object-Names.html#Key-Concepts-Object-Names) and i use
the following command to use sparc-rtems4.12-gcc to compile this program

sparc-rtems4.12-gcc --pipe -B/home/thd/development/rtems/
src/builds/erc32_1/sparc-rtems4.12/erc32/lib -specs bsp_specs -qrtems -Wall
-g -O2 -o rtems_object_try rtems_object_try.c

but when i do ./rtems_object_try I get:

./rtems_object_try: Invalid argument

I narrowed in on the above compiler command by reading the makefile as
given here(https://github.com/alanc98/rki/blob/master/Makefile).

What is it that I am missing?

Also is it necessary to use sparc-rtems4.12-gcc and not the gcc available
to me normally on my machine. When I use gcc,
I get the following error:


thd at thd-Inspiron-5537:~/development/rtems/src/programs/rtems_object$ gcc

I am not able to understand what is wrong. It would be great if you could
point that out.
Thank you,
