I use GNU Autoconf 2.63 on CentoOS 6.3 32-bit. In my configure script I check the sizes of some types, like:
AC_CHECK_SIZEOF(char) AC_CHECK_SIZEOF(int) AC_CHECK_SIZEOF(long) , but the result is always 0 when running ./configure: checking size of char... 0 checking size of int... 0 checking size of long... 0 The same configurations run fine on Mac OS X SL and Ubuntu though. Any ideas why AC_CHECK_SIZEOF returns 0 on CentOS? -- View this message in context: http://old.nabble.com/Autoconf-AC_CHECK_SIZEOF-always-0-on-CentOS-tp34267681p34267681.html Sent from the Gnu - Autoconf - Bugs mailing list archive at Nabble.com.
