You need to change it to the following code to be able to compile it with a standard compliant compiler (gcc is more compliant to the standard on this point). class JSONDeserializer { Value ParseValue(TDR type, const json_string& valueString); }; The error come from the fact that JSONDeserializer::ParseValue is a qualified name (a name with a namespace qualification), and such a name is forbidden as a method name in a class. share|improve this answer edited Dec 30 '13 at 13:11 answered Apr 12 '11 at 22:39 Sylvain Defresne 23k35474 Is ther than a day had elapsed since the release of ETSET 3.2 before it was torpedoed by a fanatical “purity of essence” http://www.fourmilab.ch/fourmilog/archives/2006-05/000699.html enhancement foisted onto software developers worldwide by the C++ cabal at the http://gcc.gnu.org/PR26785 GCC project. In every version of GCC from the get-go through 4.0, code like the following: class struggle { void struggle::propaganda(void) { } }; compiled without so much as a warning, even in persnickety “-Wall” mode. But that was then, and this is now, and while extra qualification the nugatory class qualification on "struggle::propaganda" is redundant since it's an in-line declaration within the class, it would seem to be just an example of specifying something you aren't required to in the interest of documentation—for example, when looking at a listing of a very long class declaration it reminds you of the name of the enclosing class. If error extra qualification you enter a search for: gcc "error: extra qualification" into your favourite search engine, you'll find hundreds (more than 650, from the results I got) of messages documenting Open Source software projects which have been blown away by this “enhancement” of GCC—for what good? Some suggest that this has something to with namespaces in C++: perhaps some obscure incompatibility between the use of qualifiers for class names and namespaces requires blowing away decades of carefully-maintained code. But, should that be the case, it is simply more evidence that C++ has become a legacy language, like COBOL, in which we are obliged to maintain existing code and link to libraries, but which has become demonstrably unsuitable for new software development. Now, when this particular torpedo strikes your vessel beneath the waterline minutes before (or, worse, after) a delivery milestone, it's easy to remedy: simply remove the class qualifier from the inline function declaration: write “void propaganda(void)” instead of “void struggle::propaganda(void)”. But, when doing so, ask yourself that question so appropriate when dealing with figure Login: [x] User account creation filtered due to spam. Bug26785 - "extra qualification" error gives line number of end of declaration Summary: "extra qualification" error gives line number of end of declaration Status: RESOLVED FIXED Alias: None Product: gcc Classification: Unclassified Component: c++ (show other bugs) Version: 4.1.0 Importance: P3 minor Target Milestone: 4.4.0 Assignee: Not yet assigned to anyone URL: Keywords: diagnostic Depends on: Blocks: Reported: 2006-03-21 17:03 UTC by Martin Michlmayr Modified: 2008-08-06 16:42 UTC (History) CC List: 4 users (show) debian-gcc gcc-bugs manu mueller See Also: Host: Target: Build: Known to work: Known to fail: Last reconfirmed: 2006-03-21 17:06:09 Attachments Add an attachment (proposed patch, testcase, etc.) Note You need to log in before you can comment on or make changes to this bug. Description Martin Michlmayr 2006-03-21 17:03:08 UTC The line number mentioned in the "extra qualification" error is not ideal. Instead of showing the line number on which the extra qualification actually occurs it shows the last line of the declaration. (sid)6102:tbm@deprecation: ~] cat > test.cpp class foo { foo::foo(int a, int b, int c); }; int main() { } (sid)6103:tbm@deprecation: ~] g++ test.cpp test.cpp:4: error: extra qualification `foo::' on member `foo' I'd like to see "test.cpp:2: ..." here. Presumably it checks things like that after reading a complete declaration. I would have thought it could track what the first line of the declaration was though. seen with: gcc version 4.1.0 20060219 (prerelease) (Debian 4.1-0exp9) gcc version 4.0.3 (Debian 4.0.3-1) [using -pedantic] Comment 1 Andrew Pinski 2006-03-21 17:05:28 UTC This is the crazy parser getting the line number "wrong". Comment 2 Dirk Mueller 2006-10-16 15:22:11 UTC ehm, this is the same with any warning/error message? why would this case be special? Comment 3 Martin Michlmayr 2006-10-16 15:38:57 UTC (In reply to comment #2) > ehm, this is the same with any warning/error message? why would this case be > special? I never noticed before, but it would still be nice to get this changed. Comment 4
