it seems the absolute path was the problem.
My solution is this:
ln -s /home/myuser/data/development/workspace/ngx_mymodule/src/
I don't know why the absolute path doesn't work. The oddest thing is,
that everything gets compiled perfectly well and that the binary
contains strings containing 'ngx_mymodule', so it's in there.
I'm not sure, why the path is relevant after the compile process
succeeded... but it seems to be. Can anybody explain this to me, please?
Or am I just misinterpreting anything?
sorry.. That was just the example...
I used the absolute path of course...
/home/myuser/data/development/workspace/ngx_accesskey/src/ to be exact.
