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?
I would use a more low-level macro such as AC_COMPILE_IFELSE, e.g., as
follows (not tested)
AC_COMPILE_IFELSE(
[AC_LANG_PROGRAM([@%:@include <header.h>],
[ #if LIB_VERSION >= 424242
// OK
#else
# error version too old
#endif
])
],
[ACTION-IF_OK], ACTION-IF_NOT_OK])
Cheers,
Peter
