I’ve been trying to find or write a webserver directly on L4Re (*NO* L4Linux involved) based on snapshot “l4re-snapshot-17.12”. At first, I noticed that there was already a web server in “l4re-snapshot-17.12/src/l4/pkg/ankh”. But it was broken, even if I removed the “broken” file to make, nothing was generated under “/path/to/build/pkg/ankh” except “Makefile”.
Yes, the 'broken' file is there because it is, indeed, broken, i.e. not compiling.
Then I intend to write a simple webserver (1st step a socket demo). Although there are socket APIs, I don’t know how to solve the NIC driver issues. The same code works well on Linux but failed on L4Re.
Therefore:
- Is there any way to revive the “ankh”?
- If not, is there any way/demo to write a simple webserver directly on L4Re? Or how to solve the NIC driver issues?
You're right that there's the need for a driver. Reviving ankh is quite a bit of work, and would include fixing/updating DDE first. Maybe looking into dpdk is a better approach here. Then a TCP/IP stack is required, for a simple demo lwip should work I guess (it's in the repo). Overall quite a bit of work.
