Hi,
apologies in advance for my bad english...
I'm using eVC++ 4 for developing an WinCE 5.0-Application with the
"PicoMod"-Core. In this Application, I want to use std::map like this:
typedef map<const char*, someobject*, comp_func> mymap;
The Problem is, when I try to instantiate a variable of type mymap, I get
following linker error:
ChildView.obj : error LNK2019: unresolved external symbol "public: __cdecl
std::_Lockit::_Lockit(void)" (??0_Lockit@std@@QAA@XZ) referenced in
function
"public: __cdecl std::_Tree<char const *,struct std::pair<char const *
const,int *>,struct std::map<char const *,int *,struct ltstr,class
std::allocator<int *> >::_Kfn,struct ltstr,class std::allocator<int *>
::~_Tree<char const *,struct std::pair<char const * const,int *>,structstd::map<char const *,int *,struct ltstr,class std::allocator<int *>
::_Kfn,struct ltstr,class std::allocator<int *> >(void)"(??1?$_Tree@PBDU?$pair@QBDPAH@std@@U_Kfn@?$map@PBDPAHUltstr@@V?$allocator@PAH@std@@@2@Ultstr@@V?$allocator@PAH@2@@std@@QAA@XZ)
A second error tells me the same for _Lockit::~_Lockit. By googling, I
found
out this might be a multi-/single-threading issue, but the proposed
solution
for that is changing the run-time library, which is not possible because
the
only available choice is the "CE Runtime *".
To ensure the problem was not constructed in some other class of mine, I
created a new eVC-Project, which immediately had the same error.
Anyone got a clue what the problem might be?
