[PPL-devel] Re: Locating sicstus.h

so the idea would be that once you know where `sicstus' is you also know where `sicstus.h' is.

Once you've run sicstus you can use the following sicstus code to get the relevant environment variables:

:- use_module(library(system)).

environ('SP_RT_DIR',D1) environ('SP_LIBRARY_DIR',D2) environ('SP_APP_DIR',D3)

it does not directly give you the path to sicstus.h, but it can be (always??) recovered from the value SP_APP_DIR or SP_RT_DIR I guess.

Thanks Samir. The solution

sicstus_prolog_base=$(dirname $(sicstus -f --goal "use_module(library(system)), environ('SP_APP_DIR', X), write(X), nl, halt."))

seems indeed the most reliable one. Best wishes,
