<p class="MsoNormal"><span style="font-family:"Courier New"">After accounting for the build errors in network-demos/netdemo [1] we reported here [2], we believe there is a runtime error (the error only occurs in RTEMS 5, everything seems to work in RTEMS 4.11).
We are defining a network interface assigned to a 192.168.0.0/24 subnet as we described in [2] and using a Cobham/Gaisler LEON Expandable Application Platform (LEAP) board for testing [3]. See below for information about the runtime error. The upshot, however,
is that we would like to debug the runtime error, but when building the debug target of network-demos/netdemo we get the following build error:<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Courier New""><o:p> </o:p></span></p>

<p class="MsoNormal"><span style="font-family:"Courier New""><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Courier New"">If we replace –qrtems_debug with –fvtv-debug in the Makefile, or just remove –qrtems_debug we get the following build error instead:<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-family:"Courier New""><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Courier New"">Since the linker normally tries to link against `rtems-5/bsp-install/sparc-rtems5/leon3/lib/librtemsbsp_g.a' we assumed that we needed to build a debug version of the rtems kernel + bsp. However,
we have tried building the kernel + bsp with ‘make debug’ [4] and ‘make VARIANT=debug’ [5] and neither of those approaches build ‘librtemsbsp_g.a’.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Courier New""><o:p> </o:p></span></p>
