Re: [lwip-users] How to build LwIP1.3.0 for Xilinx PPC405

[Kevin]

Thanks, Gabriele. It works as you indicated!

Is there a way to build this lwip without going through libgen? I tried to run "makefile" under lwip130/src folder inside "EDK Shell" and keep getting complains about cannot find files, so I manually add path to the include variable. Here is my modified "makefile"

By running this makefile, I still get following error:

Now, my question is: is there a quick way to automatically let powerpc-eabi-xxx know the include path without using libgen? I am sure xps GUI deal with this somewhere, but I couldn't find this underlying command. Could you please give me a help on this?

Thank you so much!

OK, so you don't need to write a makefile, but to edit the MSS file of your "software platform". This will cause the libgen command to copy lwip sources from the local repository (I.E. your xilinx installation), and generate the makefile too.
You can do that by "Software Platform Settings" dialog, both in SDK and in XPS. Select lwip130 checkbox (and if you wish the lwip options in the OS and libraries tab. This is equivalent to edit the opt.h in lwip sources).
Remember that each time you run libgen this will overwrite the lwip sources copy in your project directory.

Hope this helps.
