Hi all,
i am using momentics and qnx neutrino (education program). I have a problem
with the driver development kit:
I want to modify and make the usb class driver and I always get errors like
the following:
“undefined reference to `usbd_abort_pipe’”
I get similar errors for all used usbd functions.
Is there a special library i have to include? I use the include file
sys/usbdi.h .
Thank you
You should link against the library usbdi.
cheers, peter

Thank you,
i have the 2 static libs “libudi.a” and “libusbdi.a” from the ddk copied in
my working dir, but no success, i’ve got the same error messages.

You will need to specifically mention those libs. Use -l libname on the
cc command line. See ‘use cc’.

I am a lucky user of the Momentics IDE, and I have checked the library
paths. Maybe the problem depends on my target, (a ppc5200). Shortly I tried
to use the tan function out of the math lib, and i’ve got the same error
message…

Did you compile with:
qcc blah.c -lm -o blah
Please follow-up to newsgroup, rather than personal email.

I’m not using the IDE so I’m a little fuzzy on this.
At link time you can specify library paths “-L” and libraries “-l”.
If you only specifying library paths your only specifying half of what
you need.
Thanks to all,
I have solved the problem. The missing -lm was my fault…
