Title: [WebServer.cpp] ambiguous overload
Post by: thermoman on July 13, 2004, 03:33:26 AM

Hi,

i get this error message while trying to compile rc4:

Code: [Select]

WebServer.cpp: In function `static class wxString CWebServer::_GetTransferList(ThreadData)':
WebServer.cpp:1503: ambiguous overload for `bool ? wxString & : const char[1]'
WebServer.cpp:1503: candidates are: operator ?:(bool, wxString, wxString)
WebServer.cpp:1503:                 operator ?:(bool, const wxChar *, const char *)
WebServer.cpp:1503:                 operator ?:(bool, const wxChar *, const char *)
it is this line:

Code: [Select]

Out.Replace(wxT("[ClearCompletedButton]"),(completedAv && IsSessionAdmin(Data,sSession)) ? pThis->m_Templates.sClearCompleted : wxT(""));
i rewrote this line and substituted it with the following code which compiled without error:

Code: [Select]

       wxString tmp_thermoman;

        if (completedAv && IsSessionAdmin(Data,sSession)) {
            tmp_thermoman = pThis->m_Templates.sClearCompleted;
        } else {
            tmp_thermoman = wxT("");
        }

        Out.Replace(wxT("[ClearCompletedButton]"),tmp_thermoman);
This should be the same semantic - and it compiled well. I don't see the problem with the '?' operator. Give me a hint.

Finally found the solution myself:

You have to replace the wxT("") things with wxString("") in WebServer.cpp and DownloadClient.cpp

Could you also use wxEmptyString?  ;)

Its strange - this only occures when used in

bool ? a : b

but not in normal contect.

I gave your fix a try, and since im lazy i did it like this:
sed s/"wxT("/"wxString("/g file1.cpp > file2.cpp

However now i get:

Did my wannabe haxor sed command change something that shoulnd't be changed?

Edit:
I just took the sed command from the Debian howto. I never used sed before. Appearantly it left me with empty WebServer.cpp and DownloadClient.cpp files. If anyone else wants to use sed to replace all the wxT("") things with wxString("") do it something like this:

Code: [Select]

sed s/"wxT("/"wxString("/g WebServer.cpp > temp && mv temp WebServer.cpp && sed s/"wxT("/"wxString("/g DownloadClient.cpp > temp && mv temp DownloadClient.cpp

maybe ugly, but gets "the job done" [TM] :D

The real haxxor way:

perl -p -i -e 's/wxT\(/wxString\(/g' WebServer.cpp DownloadClient.cpp
