The external does not build on the Raspberry Pi - asio error

[lucaturchet]

Hello, I am trying to build the abl_link~ external on a raspberry Pi 4, but I get some errors related to the actual cpp code. I am not sure if it is a matter related to libpd, it seems that the errors are related to the syntax itself. After launching
make -j4 PDINCLUDEDIR=/usr/local/include/pd

I get the error:

abl_link~.cpp: In function 'void abl_link_tilde_reset(t_abl_link_tilde*, t_symbol*, int, t_atom*)': abl_link~.cpp:116:7: error: 'error' was not declared in this scope; did you mean 'asio::error'? 116 | error("abl_link~ reset: Unexpected number of parameters: %d", argc); | ^~~~~ | asio::error

and then:

abl_link~.cpp: In function 'void* abl_link_tilde_new(t_symbol*, int, t_atom*)': abl_link~.cpp:143:7: error: 'error' was not declared in this scope; did you mean 'asio::error'? 143 | error("abl_link~: Unexpected number of creation args: %d", argc); | ^~~~~ | asio::error

Could you please provide some guidance?

this is a duplicate of #29, and has been fixed with #30 (not yet merged)

Also, on Raspbian you should be able to simply install the pd-ableton-link package with apt.
