problems compiling lwip module inside pico-extras

[lealoureiro]

Hello,

Not sure if is the right place to report this issue, but i'm having problems to compile lwip lib that is inside pico-extras.

/usr/local/Cellar/arm-none-eabi-gcc/9-2019-q4-major/gcc/bin/../lib/gcc/arm-none-eabi/9.2.1/../../../../arm-none-eabi/bin/ld: CMakeFiles/rmiieth.dir/Users/leandro/Projects/pico-extras/lib/lwip/src/core/netif.c.obj: in function `netif_set_addr':

collect2: error: ld returned 1 exit status
make[2]: *** [rmiieth.elf] Error 1
make[1]: *** [CMakeFiles/rmiieth.dir/all] Error 2
make: *** [all] Error 2

The functions are defined inside acd.c but seems like this file is not listed for compilation and thus functions will be missing during linkage.

I'm trying to compile and test this project/repo: https://github.com/strags/pico-rmiieth , out of the box without modification.

OS: Mac OS X 10.15.7 (also tried inside Debian Docker image) CMake Version: 3.20.2

Thanks in advance!

Regards, Leandro

Just out of curiosity: Does this project compile for you? https://github.com/Hermann-SW/pico-webserver

lwIP is no longer in pico-extras; it is in pico-sdk as pico_lwip
