I noticed in the g-wan User Manual pdf documentation as of 10/19/2012, http://gwan.ch/download that it says:
Updating servlets (C, C++, etc.) When you need to add or update servlets located in the csp directory you can do so without stopping G-WAN (all cached files are updated in real-time).
Yet when I start gwan, it appears to compile everything in the csp directory. That would be down right ugly on a system with 1000's of .c files. Anyway, I tried updating the hello.c file just to see what happens. When I access it again, the changes do not take. I have to restart the server. Also, if I put in a new servlet, like hello2.c, I get "The requested URL was not found on this server." until I restart the server?
what gives?
G-WAN 3.3.28 64-bit (Mar 28 2012 11:24:16) - the latest version I saw in the download as of Oct 19th, 2012

This works for me. I'm running CentOS. The only issue I can find is with header files not updating.
I can't seem to replicate what you're experiencing. What OS are you on?

Gil found the answer. It was permissions. (for the linux newbie like myself) The csp directory must have the same owner/group as how the gwan server is started.
sudo ./gwan -d:www-data:www-data
If started as above, the csp directory must also be www-data as owner and group along with the actual servlet file. In my case it was the hello.c file.

Only applies to the next release which should be soon, version 3.10.x I believe. Search for the tag "g-wan" and you will see other threads where the new version is mentioned.
