I tried:
# AC_LIB_HAVE_LINKFLAGS(lib name, dependencies, includes, optional test code)
AC_LIB_HAVE_LINKFLAGS([jbig2dec],[],[],[extern void* jbig2_ctx_new(); void* t =
jbig2_ctx_new;])
=> same
I also tried adding a dummy '#include' just in case:
AC_LIB_HAVE_LINKFLAGS([jbig2dec],[],[#include <stdlib.h>],[extern void*
jbig2_ctx_new(); void* t = jbig2_ctx_new;])
=> same too :/
Just in case: to try a new M4 wording I:
- edit configure.ac
- run 'autoreconf' or 'autoconf'
- run ./configure --help | grep -i with
