14 dnl Additional macros used to configure GiNaC. We don't start our own
15 dnl additions' names with AC_ but with GINAC_ in order to steer clear of
17 dnl ===========================================================================
19 dnl Generally, it is a bad idea to put specialized header files for a library
20 dnl into a generic directory like /usr/local/include/. Instead, one should put
21 dnl them into a subdirectory. GiNaC does it, NTL does it. Unfortunately, CLN
22 dnl doesn't do so but some people choose to do it by hand. In these cases we
23 dnl need to #include <cln/cln.h>, otherwise #include <cln.h>. This macro
24 dnl tries to be clever and find out the correct way by defining the variable
25 dnl HAVE_CLN_CLN_H in config.h:
26 AC_DEFUN(GINAC_CHECK_CLN_H,
28 AC_CHECK_HEADERS(cln/cln.h, ,
29 AC_CHECK_HEADERS(cln.h, ,
30 AC_MSG_ERROR([cannot find header for Bruno Haible's CLN]);
35 dnl This macro is needed because the generic AC_CHECK_LIB doesn't work because
36 dnl C++ is more strongly typed than C. Therefore we need to work with the
37 dnl more fundamental AC_TRY_LINK instead.

76 dnl libreadline is based on the termcap functions.
77 dnl Some systems have tgetent(), tgetnum(), tgetstr(), tgetflag(), tputs(),
78 dnl tgoto() in libc, some have it in libtermcap, some have it in libncurses.
