(This is a follow up discussion of https://github.com/fricas/fricas/pull/96)
I'd like to discuss this again, to avoid problem like https://github.com/fricas/fricas/issues/110, aka to load "libspad.so" when "FRICAS" is not set. First, the binary (instead of shell script) FRICASsys should work when "FRICAS" is not set. Second, during a fricas session, we can safely assume that the environment variable "FRICAS" does not change. Third, if so, the we can use "FRICAS" from C side and use "$spadroot" in Lisp side and still be consistent. Finally, if we are considering the use case of using FRICASsys alone, aka using the Lisp image without the C part, then it is clear that we should (|getEnv| "FRICAS") once, if it does not exist, use some other default value, and store it into an variable ($spadroot) and use that variable later. - Qian -- You received this message because you are subscribed to the Google Groups "FriCAS - computer algebra system" group.
