I tried compiling /apps/tests/TestNetwork, and the same warnings were
given. (in lines 488, 570, and 592 of CTPForwardingEngineP, the
comparison
"(qe->client < CLIENT_COUNT) " is always false due to limited range of
data type) Also, I got two new errors: "app.c:(.test+0x6884):
warning: internal error: unsupported relocation error" and
"app.c:(.test+0x68ce): warning: internal error: unsupported relocation
error". In my original code, I do instantiate a CollectionSenderC, so
I doubt that's the problem. Omprakash suggested that the problem
might be my environment and/or compiler, so here's some information
about it:
nescc --version gives
nescc: 1.2.8a
gcc: gcc (GCC) 4.1.2 20080928 (prerelease) (Ubuntu 4.1.1.13ubuntu5)
and some copyright information.
The operating system is Xubuntos 2.0 (a Ubuntu distribution), and it's
the only computer I have access to which has the nescc compiler on it.
I'm not sure what other information would be useful, but I'd be glad
to provide more if you tell me what you need and how to get it.
Thanks in advance,
