SPARC-RTEMS5-GCC ignores or don't find libraries

[Vaibhav Gupta]

You need to take care of multiple flags to run sparc-rtems5-gcc
And do not make changes to RTEMS source tree, I too did that mistake once.
.
If you have successfully built RTEMS (i.e completed with step where you
need to run "make install").
.
The hello.c  gets automatically compiled and is placed to path:
{RTEMS build}/erc32/sparc-rtems5/c/erc32/testsuites/samples/hello.exe
,
.
or you can run :
$ cd ~
$ cd quick-start
$ find ./ -name \hello.exe
you will be able to get path.
.
If you want to execute it, just run
$ sparc-rtems5-run {RTEMS build}/erc32/sparc-rtems5/c/
erc32/testsuites/samples/hello.exe
(replace with the path to hello.exe , I typed, with the one you find on
your system).
.
And if you make changes to hello.c
save the changes,
just go to b-erc32 folder and run:
$ make
$ make install
and use sparc-rtems5-run to see changes in .exe file
