Lwip basic question

Hi,

First of all,

I have to make decision between InterNiche Stack and LwIP stack.

I am using opencores ethernet mac which is tested with InterNiche stack, but i don't know how to make that.

LwIP stack is formerly used in my company but for an old project that used different MAC, NIOS, IDE....

We chose lwIP because it's smaller, faster, and more reliable (and the support behind it is good). It's also free but this was a bonus - that didn't matter. The Altera TSE driver is slow and inefficient - and buggy. If you need IPv6 then lwIP is not an option for you.

After I add the path to the include path in build project properties (even if i already add it in include path & symbols), I have errors :

When I double-click on this error, it doesn't lead me to the error location, I have to manually edit file and go to the error line.

"go to error location" works well with opencores ethernet files (component in fpga and then in system library).

OK, well, I see this with all errors in Eclipse - so this is an IDE problem. I've just gotten used to it I suppose. :mad:

I suspect bad syntax handler with some C keywords like struct, typedef, enum....

I say that because I had experienced troubles with typedef keyword.

If it is too hard to implemant LwIP, I will have a look at InterNiche.

It may be hard to implement, but it will be worth it.

Maybe those include problems is related to your first post : undefined reference to netconn_new()

OR NETCONN_UDP is badly defined (exists in api.h ;-))

This wasn't my post, but I do see the error tracking bug you're talking about.
