Hi Frank,
  I switched to 6, and started working through the quick-start recipe. All went 
well until I tried to build the hello app:
peter@peter-HP:~/quick-start/app/hello$ ./waf configure 
--rtems=$HOME/quick-start/rtems/6 --rtems-bsp=arm/xilinx_zynq_zc702
Setting top to                           : /home/peter/quick-start/app/hello
Setting out to                           : 
/home/peter/quick-start/app/hello/build
Traceback (most recent call last):

field.startswith('rtems'))
StopIteration


Not sure what I did wrong.
I have attached the files I generated for the app

Pete.

Hi Frank,
THanks for responding. The output is:

peter@peter-HP:~/quick-start/src/rsb/rtems$ /usr/bin/python3-config --ldflags
-L/usr/lib/python3.10/config-3.10-x86_64-linux-gnu -L/usr/lib/x86_64-linux-gnu  
-lcrypt -ldl  -lm -lm
peter@peter-HP:~/quick-start/src/rsb/rtems$ /usr/bin/python3-config --ldflags 
--embed
-L/usr/lib/python3.10/config-3.10-x86_64-linux-gnu -L/usr/lib/x86_64-linux-gnu 
-lpython3.10 -lcrypt -ldl  -lm -lm

So I guess you are right.
I am starting pretty much from scratch, so I chose 5 as the most recent 
released version. Would I be better off switching to 6?
Pete.

Hi Pete,

this looks like bug 
https://urldefense.com/v3/__https://devel.rtems.org/ticket/4631__;!!P4SdNyxKAPE!AC1ZvL2wAQCQ7iQRpVCcyO-eP2P-xD3OJxSxyVv2nG86THYXD4jA0AyeoYw8zCGRzOtFZCoiACmEEpE5mKYzHi9gMHKQBlqzPA$

It was fixed for RTEMS 6 but may be not for RTEMS 5?

I am adding Chris Johns to CC as he fixed this bug in RTEMS 6.

If it is this bug, the cause is that on newer OS the command
`/usr/bin/python3-config --ldflags` needs an additional `--embed` option
while on older OS it does not even understand it. I am not using RTEMS 5
so maybe someone else can provide you advice.

Pete, which version of Python are you using?
What is the output of the following commands on your machine?

/usr/bin/python3-config --ldflags
/usr/bin/python3-config --ldflags --embed

Greetings
Frank
