problem with the stand alone LWIP

Hi All,

Lwip standalone version can run in Nios2 IDE6.0. following is my stage for reference.

1. unzip lwip-v1.1.zip

2. copy sopc_builder/components/altera_avalon_lan91c111 to kits/nios2_60/components

3. use setup.exe to install package into kits/nios2_60/components

4. move kits/nios2_60/components/altera_avalon_lan91c111 to sopc_builder/components

5. Use IDE to create a blank application project and move all files from lwip_web_server folder to the blank application project

6. remove .cdtbuild and added the four build paths as described in the readme file from c/c++ build of application project.

7. then, compile the project.

8. IDE will respond a lot of error as following in system library.

Regards
