[Discuss-gnuradio] Multiple Tag Debug blocks output on OS X

[Steven Knudsen]

Hi,

I have a GRC project with multiple Tag Debug blocks. Under Linux, the output appears in the console as one would expect. However, under OS X, the characters of the output appear to be “multiplexed” in some way. The problem goes away if I have only one Tag Debug block enabled. Out of 4 different Tag Debug blocks, it doesn’t seem to matter which subset with more than two is active; the garbled output happens.

It also doesn’t seem to matter if GRC is launched from the built-in Apple Terminal or from an XQuartz terminal.

Has anyone else seen this?

My guess (uneducated at this point) is that maybe there is an issue with an underlying library that is involved in output to stdout, maybe?

Again, everything works perfectly under Linux. GNU Radio on both Linux and OS X is completely up-to-date.

I can live with this, but would like to know what may be happening.
