Subject [jira] Resolved: (STDCXX-873) [EDG eccp 3.9/SuSE 9] wcslen() not declared in <wchar.h>
Date Tue, 15 Apr 2008 17:11:05 GMT

     [ https://issues.apache.org/jira/browse/STDCXX-873?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Martin Sebor resolved STDCXX-873.
---------------------------------

    Resolution: Fixed

Turns out the problem is caused by the GNU libc headers which make use of the {{long long}}
type. Since we compile with the EDG eccp -A option for strict C++ 98 conformance the compiler
errors out on the {{long long}} type in all config tests that #include such headers. The fix
committed in [rev648332|http://svn.apache.org/viewvc?rev=648332&view=rev] suppresses the
error during the configuration process.

Here's the command line and the compiler output for the config test for {{wcslen()}}:

{noformat}

> The C++ '98 function {{wcslen()}} required to be declared in {{<wchar.h>}} and
{{<cwchar>}} is not declared in our version of the former header when compiling with
EDG eccp on SuSE Linux 9. The function is declared in {{<cwchar>}} as expected.
