Re: [lwip-users] Updating from 0.5.3 to 0.6.2

Hi,

I'm just curious, I'm using 0.6.0. Is there a netconn_delete bug there as
well?

Thanks
Nishen

Subject: [lwip-users] Updating from 0.5.3 to 0.6.2


Hi all,

I've migrated my MPC port of lwip to version 0.6.2. I've implemented the new
driver architecture, I've adopted sys_arch.c (timeout, ...) and removed the
netconn_delete bug. What I see is that ping works fine, but using http or
telnet hangs, means that I see no response. The debug log shows me that the
ESTABLISHED state is reached. Ping works further on. I append a log to this
mail.

Trying to use LWIP_EVENT_API leads to unresolved symbols and the following
bug in line 507 of file tcp_in.c:
LWIP_ASSERT("pcb->accept != NULL", pcb->accept != NULL);
pcb->accept not known. Is the event API ready to use?

Due to the case that CVS does not work with our proxy server I depend on zip
paket of lwip, which does not contain the proj and the arch part! (Is it
possible to add these files in future releases?) So I can't see if something
more has changed.

Can perhaps anybody send me the latest CVS stable tree as gz or zip?

I really appreciate your help. What can I do to solve this problem?
