Thank you for your suggestions.
I was under the impression that the other web-servers needed PHP or similar in order to be able to do the following:
1. Via the web-page allow users to supply information which then is stored in a config file on the rasperry (like a name for the audio player, or ALSA settings).
2. Then via the web-page execute a script on the raspberry which would restart the player with the new settings.
According to the developer of Oliweb server this is supported out of the box with this little web-server.
Therefore, I'm still very interested in figuring out how to "make" in tinycore.
Is it Ok what I have described in a few posts above? If it is the right method in tinycore, then I will need to have a look in the makefile to see if there is a problem.
If the problem is missing linux headers as suggested by Rich, how do I manage this?
