Hi there,

would you please consider adding to ciao_prolog.h the definition of macros allowing to determine the Ciao Prolog version at compile time? I mean, like the macros

SICSTUS_MAJOR_VERSION SICSTUS_MINOR_VERSION SICSTUS_REVISION_VERSION SICSTUS_BETA_VERSION

defined by sicstus.h and the macro

PLVERSION

by SWI-Prolog.h.

Sorry for the delay in the answer... I have just committed a patch to define

CIAO_MAJOR_VERSION CIAO_MINOR_VERSION CIAO_PATCH_VERSION CIAO_SVNREV

You can check for older Ciao version by checking that any of them are undefined, e.g.

#if !defined(CIAO_MAJOR_VERSION) ...Ciao 1.10... #elif CIAO_MAJOR_VERSION == 1 && CIAO_MINOR_VERSION >= 13 ... #endif

Please, tell me if it is enough for PPL.

Cheers, Jose
