-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 According to Sam Steingold on 3/14/2008 9:41 AM: Hello Sam, and sorry for the delayed reply, | the problem is no with AC_LIB_FROMPACKAGE but with AC_LIB_LINKFLAGS, | AC_CHECK_HEADERS, and AC_SEARCH_LIBS. | | my problem is that cl_cv_have_ffcall is an amalgamation of other checked | variables. | | are you suggesting that what I need is | | AC_DEFUN([CL_FFCALL],[dnl | AC_ARG_WITH([ffcall], | [AC_HELP_STRING([--with-ffcall],[use FFCALL (default is YES, if | present)])], | [cl_use_ffcall=$withval],[cl_use_ffcall=default]) | if test $cl_use_ffcall != no; then | AC_LIB_FROMPACKAGE(avcall,libffcall) I'd get in the habit of consistent quoting: AC_LIB_FROMPACKAGE([avcall],[libffcall]) | AC_LIB_FROMPACKAGE(callback,libffcall) | AC_LIB_LINKFLAGS([avcall]) | AC_LIB_LINKFLAGS([callback]) | AC_CHECK_HEADERS(avcall.h callback.h) | if test "$ac_cv_header_avcall_h" = yes \ | ~ -a "$ac_cv_header_callback_h" = yes 'test cond1 -a cond2' is not portable. Use 'test cond1 && test cond2'. | then | cl_save_LIBS="$LIBS" | AC_LIB_APPENDTOVAR([LIBS], [$LIBAVCALL]) | AC_LIB_APPENDTOVAR([LIBS], [$LIBCALLBACK]) | AC_SEARCH_LIBS(__builtin_avcall) | AC_SEARCH_LIBS(trampoline_r_data0) | if test "$ac_cv_search___builtin_avcall" = no \ | ~ -o "$ac_cv_search_trampoline_r_data0" = no Likewise for 'test cond1 -o cond2'. | then LIBS=$cl_save_LIBS | fi | fi | AC_CACHE_CHECK([whether libffcall is installed],[cl_cv_have_ffcall], | [if test "$ac_cv_header_avcall_h" = yes \ | ~ -a "$ac_cv_header_callback_h" = yes \ | ~ -a "$ac_cv_search___builtin_avcall" != no \ | ~ -a "$ac_cv_search_trampoline_r_data0" != no | then cl_cv_have_ffcall=yes | else cl_cv_have_ffcall=no | fi]) | if test $cl_use_ffcall = yes -a $cl_cv_have_ffcall = no; then Yes, this approach looks like it will avoid the nested messages. - -- Don't work too hard, make some time for fun as well!
