When using macros like AC_CHECK_LIB for example, the C code generated by autoconf does not compile when -Wstrict-prototypes and -Werror are set in the CFLAGS, and hence the test fails. (error: function declaration isn’t a prototype) etc.
Here is a patch that fixes this problem. diff -Naur autoconf/lib/autoconf/c.m4 autoconf.new/lib/autoconf/c.m4 --- autoconf/lib/autoconf/c.m4 2008-04-06 00:04:48.000000000 +0100 +++ autoconf.new/lib/autoconf/c.m4 2008-09-14 23:42:44.000000000 +0100 @@ -202,7 +202,7 @@ m4_ifdef([_AC_LANG_PROGRAM_C_F77_HOOKS], [_AC_LANG_PROGRAM_C_F77_HOOKS])[]dnl m4_ifdef([_AC_LANG_PROGRAM_C_FC_HOOKS], [_AC_LANG_PROGRAM_C_FC_HOOKS])[]dnl int -main () +main (void) { dnl Do *not* indent the following line: there may be CPP directives. dnl Don't move the `;' right after for the same reason. @@ -224,7 +224,7 @@ #ifdef __cplusplus extern "C" #endif -char $2 ();])], [return $2 ();])]) +char $2 (void);])], [return $2 ();])]) # AC_LANG_FUNC_LINK_TRY(C)(FUNCTION) @@ -266,7 +266,7 @@ #ifdef __cplusplus extern "C" #endif -char $1 (); +char $1 (void); /* The GNU C library defines this for functions which it implements to always fail with ENOSYS.
