[jira] Commented: (STDCXX-988) [gcc 4.3.0] /usr/include/limits.h has not been included from include/ansi/limits.h

["Martin Sebor (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/STDCXX-988?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12611207#action_12611207 ] 

Martin Sebor commented on STDCXX-988:
-------------------------------------

Hmm. In 4.2.1, [{{<limits.h>}}|https://svn.apache.org/viewvc/stdcxx/tags/4.2.1/include/ansi/limits.h?view=markup] uses the gcc extension {{#include_next}} to include the compiler's {{<limits.h>}}. That file also uses {{#include_next <limits.h>}} to bring in the system header. The tail end of gcc 4.3.0 {{<limits.h>}} is below. It looks as though this directive, instead of finding the system header finds our own {{<limits.h>}} again, possibly because we fail to {{#define _GCC_NEXT_LIMITS_H}}...

{noformat}
    115 #endif /* _LIMITS_H___ */
    116 /* This administrivia gets added to the end of limits.h
    117    if the system has its own version of limits.h.  */
    118 
    119 #else /* not _GCC_LIMITS_H_ */
    120 
    121 #ifdef _GCC_NEXT_LIMITS_H
    122 #include_next <limits.h>                /* recurse down to the real one     122 */
    123 #endif
    124 
    125 #endif /* not _GCC_LIMITS_H_ */

>   The regression tests of the asio library from boost are [failed to compile|http://beta.boost.org/development/tests/trunk/developer/output/gcc-4-3-0-stdcxx-4-2-2_x86_64-boost-bin-v2-libs-asio-test-basic_datagram_socket-test-gcc-4-3-0_stdcxx_422-debug-address-model-64-architecture-x86-instruction-set-nocona-stdlib-stdcxx-4-2-2-threading-multi.html] due to undefined symbol IOV_MAX. According to POSIX this symbol should be defined in <limits.h> header. But when compiling with stdcxx the /usr/include/limits.h file has not been included at all.
