[zeromq-dev] Small issue compiling zmq

[Paulo Henrique Silva]

Hi,

I had just a small issue while compiling zmq 0.6.1. After a run of
estimate_cpu_freq I exported PERF_CPU_FREQUENCY as instructed but
after make I got:

make[3]: Entrando no diretório
`/home/henrique/ph/guarilha/zmq-0.6.1/perf/tests/zmq'
if g++ -DHAVE_CONFIG_H -I. -I. -I../../../libzmq/zmq

'local_lat.cpp' || echo './'`local_lat.cpp; \
	then mv -f ".deps/local_lat-local_lat.Tpo"
".deps/local_lat-local_lat.Po"; else rm -f
".deps/local_lat-local_lat.Tpo"; exit 1; fi

make[3]: ** [local_lat-local_lat.o] Erro 1

Looks like g++ 4.3.3 on Ubuntu 9.04 doesn't like my
PERF_CPU_FREQUENCY. After a quick google I found that I can (and
probably should) explicitly declare the constant unsigned on my export
to make g++ happy, like

-DPERF_CPU_FREQUENCY=2194499568UL

Thanks for the great system,
