std::ifstream eclipse and Win32

raulpuro (8)
Hi,

I'm using eclipse + boost + mode -std = c ++ 11, but the compiler gives me error, this program works properly on linux but I need to compile it on Windows XP.

I appreciate your help.

vector<Buffer> desempaquetar (Path const& fname, Path const& dname) {
std::ifstream f(fname.c_str(), std::ios::binary);
ifbuf wr(f);
auto parts = get_fabs(wr);
int i = 0;
for (auto & p: parts) {
------

Error:
void std::basic_ifstream<_CharT, _Traits>::open(const char*, std::ios_base::openmode) [with _CharT = char; _Traits = std::char_traits<char>; std::ios_base::openmode = std::_Ios_Openmode]

Greetings.

Please copy and paste the exact error message in full and indicate which line it is on.

Thanks for your reply, the error is in the lines.

std :: ifstream f (fname.c_str (), std :: ios :: binary);
std :: ofstream f (save_to.c_str (), std :: ios :: binary);


vector<Buffer> desempaquetar(Path const& fname, Path const& dname) {

std::ifstream f(fname.c_str(), std::ios::binary);
ifbuf wr(f);
auto parts = get_descomprimir(wr);

int i = 0;
for (auto & p: parts) {
Path save_to = dname/Path(format("part%||.b", i));
std::ofstream f(save_to.c_str(), std::ios::binary);
f.write(reinterpret_cast<char*>(&p[0]), p.size());
f.close();

++i;
}

return parts;
}

Well, the full log as you can see has more errors but I think they are all for the same reason.

Hi,

Well, this is not a project made for me, i'm trying to adapt him to decode a game, i deleted the file osdep.h, i did not know how to adapt the file osdep.h to windows and thought it was not important ... but in linux operating properly. The creator does not offer support.

Well, if i change the conversion to string, that part compiles but does not understand why it works on linux and xp no.

void save_png(Path const& filename, Image & image, uint width, uint height, bool overwrite=false)

	bool exist = boost::filesystem::exists(filename);

}



P.D. Now I get an error on line std::ifstream f((dir/"pal.PAL"));

Hi,

You ask me where encode is Declared? well this is the link of the class.

#ifdef LODEPNG_COMPILE_DISK
unsigned encode(const std::string& filename,
                const unsigned char* in, unsigned w, unsigned h,

  return encode(filename, in.empty() ? 0 : &in[0], w, h, colortype, bitdepth);
}


But that part now works using filename.string ()

Sorry my English is very poor.

Thanks.
