[lwip-users] Need help compiling LWIP

[Anmol Sehgal]

Hi Sylvain,

 

We are trying to compile LWIP-2.0.2 library, which we downloaded from the URL: http://download.savannah.nongnu.org/releases/lwip/lwip-2.0.2.zip

 

We also downloaded the working git project for LWIP-1.4.1 from the URL: https://github.com/digitalsorcery/LWIPAndroidJNI

And in a similar way, we are trying to build LWIP-2.0.2 in the above-mentioned project, but getting compilation errors.

Please find below the  error logs :

Any help would be appreciated.
