Playing tracks with E260 simulator

[OldSchool]

Hello,

I'm new here, so please re-direct me if I've posted to the wrong forum; I haven't seen anything specific to simulator issues.

I'm attempting to run a new WPS on the E260 simulator (it runs on the target, but I want to tweak it a bit). I've built the simulator from source, and it runs on my PC except that when I try to play a track, the following errors appear in the Cygwin window, and the simulator WPS jumps the the next track in the play list:

failed to load archos/_temp_codec0.dll
dlopen(archos/_temp_codec0.dll): d~ûwxøwÿÿÿÿ´û5ÌÅX|´û5;ÆX|

I suspect I've done something wrong in building the simulator, but any help would be much appreciated.

Did you make and make install the simulator, or did you attempt to extract a regular sandisk build to the simulator folder (this is wrong)?

I used the instructions from:

"The Simplified Guide To Compiling The Rockbox Source Code"

- so yes, I did the make and make install - I'm using the Cygwin environment.

I've got it working now. I did an svn update and repeated the steps in the documentation.

BTW: Is there a way to log Cygwin sessions to a text file?

Thanks for your help.

You can redirect output as in a normal linux terminal:

That creates a log file, but there's nothing in it. I'm guessing the file isn't closed properly when I kill the simulator. Sorry, no Linux experience.

You don't need to close redirected files.  If you're not getting output, I'd guess its because you're not redirecting the output correctly.  What did you type?

Sorry, no Linux experience.

This works the same way on Windows.

So much for that excuse. :-)

What I typed (excluding the "$" prompt) was:

$ ./rockboxui.exe > rockboxui.log

From the ~/rockbox/sim directory, this starts the simulator and creates the ".log" file, but the log file is empty after I stop the simulator.

I also tried the examples from the linuxsa.org site:

$ echo This is a line of text > /tmp/file.txt
$ echo This is another line   >> /tmp/file.txt

Both of these work as advertised.

Thanks again for your help (and patience).

Try ./rockboxui.exe &> rockboxui.log

This might be a stupid question, but is there a reason you haven't just downloaded the pre-built simulator?  Unless you're creating your own customized build it should be enough to test-run a WPS.

Llorean:

Yes, that works. Thanks! I've done some more digging as well. I gather that ">" redirects "standard output" and "&>" redirects both "standard output" and "standard error"; the simulator code writes to "stderr",  correct (more-or-less)? Using "2>" also works to redirect just stderr.

MarcGuay:

I'm trying to learn the Cygwin environment. I did do some C programming - many moons ago - thought I might be able to contribute to RB eventually. It looks like I'm off to a slow start I'm afraid.

Cheers
