Hi, my software uses an extern library which has its version number in it header.h like following: #define LIB_VERSION 424242 I need to check this version number (because the API was changed and this introduced an incompatibility). I think about something like AC_CHECK_DEFINE_VALUE... bug nothing like that seems to exist. Does someone knows how to do that?
