Thanks for reporting this. I can confirm this on Solaris 10, even with CVS Autoconf. The issue is that /lib/cpp is found as preprocessor, it does not understand the `#error' directive, but `#error' is used in system headers: $ echo '#include <stdio.h>' | /lib/cpp - >/dev/null; echo $? "/usr/include/sys/isa_defs.h", line 500: undefined control 2 $ sed -n 500p /usr/include/sys/isa_defs.h #error "ISA not supported" I think it's only the test that needs adjusted though, not the Autoconf macros: they correctly choose `cc -E' as preprocessor, which does understand `#error': $ echo '#include <stdio.h>' | cc -E - >/dev/null; echo $? 0 Cheers, Ralf > ## ------------------------ ## > ## Summary of the failures. ## > ## ------------------------ ## > Failed tests: > GNU Autoconf 2.59 test suite test groups: > > NUM: FILENAME:LINE TEST-GROUP-NAME > KEYWORDS > > 54: c.at:142 AC_PROG_CPP without warnings > ## ---------------------- ## > ## Detailed failed tests. ## > ## ---------------------- ## > > 54. c.at:142: testing ... > c.at:145: /lib/cpp </dev/null || exit 77 *snip* > checking how to run the C preprocessor... ./mycpp > checking for egrep... egrep > checking for ANSI C header files... yes > checking for sys/types.h... yes > checking for sys/stat.h... yes > checking for stdlib.h... yes > checking for string.h... yes > checking for memory.h... yes > checking for strings.h... yes > checking for inttypes.h... yes > checking for stdint.h... yes > checking for unistd.h... yes > checking stdio.h usability... yes > checking stdio.h presence... no > checking for stdio.h... no > checking autoconf_io.h usability... no > checking autoconf_io.h presence... no > checking for autoconf_io.h... no > configure: creating ./config.status > config.status: creating config.h > c.at:161: cat state-ls.after > No differences encountered > No differences encountered > c.at:166: sed '/#/!d > /INTTYPES/d > /MEMORY/d > /PACKAGE_/d > /STDC_HEADERS/d > /STDINT/d > /STDLIB/d > /STRING/d > /SYS_STAT/d > /SYS_TYPES/d > /UNISTD/d' config.h > No differences encountered > --- - Tue Mar 7 06:09:02 2006 > +++ /usr/tmp/local/autoconf/016/autoconf-2.59/tests/testsuite.dir/at-stdout > Tue Mar 7 06:09:02 2006 > @@ -1,3 +1,3 @@ > /* #undef HAVE_AUTOCONF_IO_H */ > -#define HAVE_STDIO_H 1 > +/* #undef HAVE_STDIO_H */ > > 54. c.at:142: 54.
