[jira] Created: (STDCXX-344) [Sun C++] warnings on
std::strstream::rdbuf hiding std::ios::rdbuf
[Sun C++] warnings on std::strstream::rdbuf hiding std::ios::rdbuf
------------------------------------------------------------------
Key: STDCXX-344
URL: https://issues.apache.org/jira/browse/STDCXX-344
Project: C++ Standard Library
Issue Type: Bug
Components: 27. Input/Output
Affects Versions: 4.1.2, 4.1.3
Environment: Sun C++
Reporter: Martin Sebor
Priority: Minor
Compiling the header strstream causes Sun C++ to emit warnings like those below:
CC -c -D_RWSTDDEBUG -mt -D_RWSTD_USE_CONFIG -I/amd/devco/sebor/dev/stdlib/include -I/build/sebor/sunpro-5.8.j8/include -library=%none -g +w /amd/devco/sebor/dev/stdlib/src/strstream.cpp
"/amd/devco/sebor/dev/stdlib/include/strstream", line 188: Warning: std::istrstream::rdbuf hides the function std::ios::rdbuf(std::streambuf *).
"/amd/devco/sebor/dev/stdlib/include/strstream", line 226: Warning: std::ostrstream::rdbuf hides the function std::ios::rdbuf(std::streambuf *).
"/amd/devco/sebor/dev/stdlib/include/strstream", line 266: Warning: std::strstream::rdbuf hides the function std::ios::rdbuf(std::streambuf *).
3 Warning(s) detected.

[jira] Commented: (STDCXX-344) [Sun C++] warnings on
std::strstream::rdbuf hiding std::ios::rdbuf

Martin Sebor commented on STDCXX-344:
-------------------------------------
This affects not only the library build (as shown above) but also any other translation unit that #includes <sstream> (and uses a specialization of one of the class templates defined there). For instance, here's a warning issued for the example program alg1.cpp:
CC -c -D_RWSTDDEBUG -mt -D_RWSTD_USE_CONFIG -I/amd/devco/sebor/dev/stdlib/include -I/build/sebor/sunpro-5.8.j8/include -I/amd/devco/sebor/dev/stdlib/examples/include -library=%none -g +w /amd/devco/sebor/dev/stdlib/examples/tutorial/alg1.cpp
"/amd/devco/sebor/dev/stdlib/include/sstream", line 362: Warning: std::ostringstream::rdbuf hides the function std::ios::rdbuf(std::streambuf *).
"/amd/devco/sebor/dev/stdlib/examples/tutorial/alg1.cpp", line 148: Where: While specializing "std::ostringstream ".
"/amd/devco/sebor/dev/stdlib/examples/tutorial/alg1.cpp", line 148: Where: Specialized in non-template code.
1 Warning(s) detected.

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 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

-------------------------------------
Starting with 5.6, Sun C++ also provides the -errtag option to selectively disable individual warnings. See for example this thread for a discussion of the option: http://forum.java.sun.com/thread.jspa?threadID=5163903

Martin Sebor commented on STDCXX-344:
-------------------------------------
Sun handles this by wrapping their iostream templates in a pair of #pragma disable_warn/enable_warn directives. The downside of this approach is that the pragmas silence all warnings, including those we might want to see.
