Hi, guys. I'm new to Autoconf. Recently I wrote an very, very simple example of using autotools. The example worked OK(all worked OK, including generated Makefiles). But when I added macro AC_CHECK_HEADERS([...]) and it went well to generate configure shell script. So I ran ./configure, it's OK! Still I checked config.log, and found there is an error showing: "error: ac_nonexistent.h, no such file or directory." ... "Compilation terminated." Fortunately that is the only error which appeared several times in the config.log file. I tried the same example on both Fedora 14 and RHEL 6.0, similar situations were encountered. So, can someone explain what is going on. Someone people said that ac_nonexistent.h error is expected when developers use AC_CHECK_HEADERS() macro if the target header files do exist. Is that true? Best wishes. _______________________________________________ Autoconf mailing list Autoconf@xxxxxxx http://lists.gnu.org/mailman/listinfo/autoconf
