Subject [jira] Commented: (STDCXX-344) [Sun C++] warnings on std::strstream::rdbuf hiding std::ios::rdbuf
Date Fri, 24 Aug 2007 00:06:31 GMT

    [ https://issues.apache.org/jira/browse/STDCXX-344?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12522321
] 

Martin Sebor commented on STDCXX-344:
-------------------------------------

Based on the Sun C++ 5.9 output with the -errtags option, the flag that silences the warning
is -erroff=hidef:

$ CC -c -mt -I/amd/devco/sebor/stdcxx/include -I/build/sebor/stdcxx-suncc-5.9-12d/include
 -library=%none -O  -m32 +w -errtags -KPIC  /amd/devco/sebor/stdcxx/src/strstream.cpp
"/amd/devco/sebor/stdcxx/include/strstream", line 195: Warning, hidef: std::istrstream::rdbuf
hides the function std::ios::rdbuf(std::streambuf *).
"/amd/devco/sebor/stdcxx/include/strstream", line 233: Warning, hidef: std::ostrstream::rdbuf
hides the function std::ios::rdbuf(std::streambuf *).
"/amd/devco/sebor/stdcxx/include/strstream", line 273: Warning, hidef: std::strstream::rdbuf
hides the function std::ios::rdbuf(std::streambuf *).
3 Warning(s) detected.
$

With -erroff=hide:

$ CC -c -mt -I/amd/devco/sebor/stdcxx/include -I/build/sebor/stdcxx-suncc-5.9-12d/include
 -library=%none -O  -m32 +w -erroff=hidef -KPIC  /amd/devco/sebor/stdcxx/src/strstream.cpp
