installing ibx with ocaml 4.01.0 on osx maverick

[Christophe Ollier]

I am trying to install ibx. Was working before I upgraded to 4.01.0. Are you aware of any issues?

The following actions will be performed: - install ibx.0.7.1 1 to install | 0 to reinstall | 0 to upgrade | 0 to downgrade | 0 to remove

Hi, I assume that this is a compatibility issue with a newer version of Core in which the transfer function is no longer present in the Queue module. I will fix that once I find some time.

[Christophe Ollier]

Thank your for taking care of the issue. Do you know which version of core I should use and as I am new with ocaml how I should use it (opam install core-x.xx ?)

[Oliver Gu]

On my machine Core 109.55.02 does not produce the above compilation error. You should be able to install it via opam install core.109.55.2 after removing your current core package.

[Oliver Gu]

The problem is fixed and tested with core 111.06.00.

[Christophe Ollier]

many thanks. I am going to test it.

[Christophe Ollier]

Thanks Oliver. It works now on osx and async 111.03.00 core 111.06.00 and ibx 0.7.2. Now I don't now if it is related to a change in Core but when I run ./plot_hist_bars.native AAPL, the chart is drawing (gnuplot wxt window open) but close immediatly. It was not the case before

[Oliver Gu]

Hi, I don't think that the issue is related to Core. It probably has something to do with gnuplot. However, I was only able to reproduce your bug by removing the persist string on line 8 of the gnuplot.ml file. Maybe there is better way/command to persist your plot.

[Christophe Ollier]

Hi. It might be related to Pipe that close gnuplot (here about ruby https://stackoverflow.com/questions/16363350/piped-program-window-closes-instantly). But I don't know how to set it up with ocaml.
