Thank you. For the record, this works: #+name: gnc_cav #+header: :includes '("<iostream>" "<ginac/ginac.h>") #+header: :libs -I/usr/local/include -L/usr/local/lib -lginac -lcln #+header: :flags -std=c++17 #+header: :namespaces std GiNaC #+header: :var job="vectors" :var vol=113.13115406160385926 :var r=1.0995524816924328312 #+header: :var a=4.916 :var c=5.4054 #+header: :main no Note the :libs line specifies an include path. A bit unintuitive, but it does the job. Specifying a path in the :includes does not work (and nothing in the docs suggests that it should). By the way, 'C-c C-v v' also provides access to the file sent for compilation. Thanks again, Roger
