c++ - gcc (mac/linux) error no matching function for call while VisualStudio compiles ok -

-

i've got problem cross-platform compile. code below compiles on win, mac , linux (program qt based) in order make compile on mac , linux have defined if/else.

windows compiler (vs2010) finds definition mac (gcc4.2) , linux (ubuntu12lts) cant find it...

any ideas? maybe im missing technical terminology in order search this? want able use "table->setmark(i,myobj());" systems doesnt seem have platform specific code.

///// .h    void setmark(int row, myobj& mark)        { value(row).setmark(mark); }    const myobj& getmark(int row) const       { return value(row).getmark(); } /////   ///// .cpp    myobj obj;    bool ret = false, ifhandled = false;    m_root_command.evaluate(obj,ret,ifhandled);     if (m_marked) {       table *table = m_thisobj.gettable();       (int = 0; < table->getrowcount(); i++) { #if defined(_win32)          // works in windows, fails compile          // on other platforms error below          table->setmark(i,myobj()); #else          // want rid of workaround          // , use above code platforms          myobj objtmp = myobj();          table->setmark(i,objtmp); #endif       }       m_marked = false;    } /////  ///// error program.cpp: in member function 'myobj program::evaluate()': program.cpp:264:36: error: no matching function call 'table::setmark(int&, myobj)' program.cpp:264:36: note: candidate is: table.h:326:9: note: void table::setmark(int, myobj&) table.h:326:9: note:   no known conversion argument 2 'myobj' 'myobj&' make: *** [program.o] error 1 /////

you cannot bind temporary non-const reference. use table->setmark(i,myobj()); need change declaration

void setmark(int row, myobj& mark)

into

void setmark(int row, const myobj& mark)

likewise setmark function delegates to.

edit: fact works in vs apparently known bug/feature
