[solved] How can I start another plugin?

[gnu]

I wrote a little, hacky viewer that opens a mp3 file, extracts the unsynced lyrics, saves them to a file  and opens the file with the text viewer plugin. The extracting of the lyrics itself works OK, but I'm having problems with displaying them.
I simply wanted to start the text viewer plugin from within my plugin, but I was told this is impossible.
Is there really no way to start another plugin? It wouldn't have to run simultanosly to my plugin, it would only have to be started AFTER my plugin has terminated. How can I do that?

p.s.: I would ask this on IRC, but my browser seems to crash after a few minutes every time I open the IRC channel.... ??

One possible cause is stack exhaustion, since the target will almost certainly have less available stack space than the sim. For example, if you declare a large array inside a function, this will eat up a huge amount of stack space. Might it be that?

EDIT: The original title of this thread was "Plugin works in sim but not on target" - hence my slightly cryptic reply.

Sorry, now I edited the title of my thread so it actually describes what I want.

I want my plugin to start another plugin. Can I do that?

Only one plugin can run at a time but it may be possible to tell rockbox to start another plugin from inside a plugin, which will then replace the currently running one. Check out how rockbox loads plugins and add that function(s) to the plugin api and try it out

Yes it is possible. Take a look at plugin_load in plugin.h.

[gnu]

Well, I tried that and it does not work. I always get the following error message from cygwin.

Code: [Select]

/home/Admin/rockbox/apps/plugins/lyric_viewer.c:25: undefined reference to `_plugin_load'
collect2: ld returned 1 exit status
make[2]: *** [/home/Admin/rockbox/sim_x5/apps/plugins/lyric_viewer.rock] Error 1

This is quite strange, since the function "plugin_load" is declared in plugin.h and I've included this .h file!.
And why does the error message say " _plugin_load"?

I'm out of my (admittedly quite limited ) wits, so I've attached my lyric_viewer.c; the only important bit is the "plugin_load" at the end of it.

You need to do rb->plugin_load because the function is a member of the rockbox plugin api structure.

[gnu]

No, it's not.
I get something like "the struct plugin_api has no member 'plugin_load'" when I try that.
As far as I can tell, it's a 'normal' function declared inside of plugin.h; but nevertheless my plugin can't see it...

If you just made this plugin for yourself and have no desire to make it part of commercially released Rockbox you could just add it to the plugin API.
It would be bad practice though because of the redundancy but it would work.

There's no "commercially" released Rockbox...

Solved - I used the list widget to display my text.
