When trying to build midisnoop-0.1.2 I get the following error:

This is on CentOS 6.3 with rtmidi 2.0.1 installed from source with ALSA and
Jack support built in.

What version of Qt are you compiling against?

Comment #2 on issue 2 by adr-goog...@uridium.org: build error

QT 4.6.2, the version that ships with CentOS 6.3.

I found the following related discussion:
http://forums.openpilot.org/topic/3204-is-qt-47-mandatory-now/

Would it be possible to use 'toTime_t' instead of 'toMSecsSinceEpoch' as
suggested in that thread so that midisnoop builds with QT < 4.7 too?

QT is a fundamental system package with loads of dependencies so
unfortunately I can't upgrade it to a newer version.

The resolution of toTime_t () is seconds, which isn't useful for these
timestamps. I'll do a bit of research later on how to solve this problem.

I've added what I *believe* is a fix to trunk. Check the source out from
trunk and let me know if the fix works for you.

Many thanks! Midisnoop now builds without errors on Centos 6.3 and the
program runs fine when I launch it, so I guess you can close this issue.
I haven't tested snooping actual MIDI traffic yet, but if I notice any
time-stamp problems when doing that I will open a new issue.
