Title: New wxSmith/wxSmithlib compiler option caused a compiler error
Post by: yesno on November 03, 2010, 09:09:11 am

The error message was: "cc1plus.exe: error: unrecognized command line option "-Wno-attributes""
All ran fine after i have removed it from wxSmith.cbp (without error messages)

My compiler is MinGW 4.4.0 on WinXPSP3 (MinGW 3.4.5 doesn't know this option, too)
The svn revision is 6817 (rep. 6796)
The unknown option was introduced in revision 6756

The whole commandline was:
mingw32-g++.exe -Wall -g -pipe -mthreads -fmessage-length=0 -fexceptions -Winvalid-pch -Wno-attributes -DHAVE_W32API_H -D__WXMSW__ -DWXUSINGDLL -DcbDEBUG -DCB_PRECOMP -DWX_PRECOMP -DBUILDING_PLUGIN -DwxUSE_UNICODE -DWXMAKINGDLL_PROPGRID -DwxPG_USE_WXMODULE=0 -march=i586 -Wall -IC:/Programme/wxWidgets/lib-2810440/gcc_lib/gcc_dll/mswu -IC:/Programme/wxWidgets/include-2810440 -I../../../include -I../../../sdk/wxpropgrid/include -I../../../sdk/wxscintilla/include -I../../../include/scripting/include -I../../../include/scripting/squirrel -I../../../include/scripting/sqplus -I../../../include/scripting/bindings -I../../../include/mozilla_chardet -I. -IC:/Programme/MinGW-4.4.0/include -IC:/Programme/CodeBlocks/include -IC:/SRC-Extern/codeblocks/trunk/src/plugins/contrib/wxSmith/properties -IC:/SRC-Extern/codeblocks/trunk/src/plugins/contrib/wxSmith -c C:/SRC-Extern/codeblocks/trunk/src/plugins/contrib/wxSmith/properties/wxsarraystringproperty.cpp -o ../../../.objs/plugins/contrib/wxSmithLib/properties/wxsarraystringproperty.o

It's a valid option in gcc 4.4.5

Quote from: http://gcc.gnu.org/onlinedocs/gcc-4.4.5/gcc/Warning-Options.html#index-Wattributes-384

-Wno-attributes
    Do not warn if an unexpected __attribute__ is used, such as unrecognized attributes, function attributes applied to variables, etc. This will not stop errors for incorrect use of supported attributes.

and was valid in gcc 4.3.5 also: http://gcc.gnu.org/onlinedocs/gcc-4.3.5/gcc/Warning-Options.html#index-Wattributes-378 (http://gcc.gnu.org/onlinedocs/gcc-4.3.5/gcc/Warning-Options.html#index-Wattributes-378).

I did not test MinGW 4.4.0, but are you sure the correct compiler is used ?
