fatal error: 'chrono' file not found

[LudovicRousseau]

On Mac OS X I have:

In file included from LibusbTest.cpp:18:
In file included from ../headers/libusbpp.h:3:
In file included from ../headers/device.h:2:
In file included from ../headers/Configuration.h:5:
In file included from ../headers/interface.h:6:

../headers/Transfer.h:4:10: fatal error: 'chrono' file not found
# include <chrono>

 ^

1 error generated.
make: **\* [LibusbTest] Error 1```

I also do not have the `<future>` header.

I guess that is because my C++ compiler (clang) is not yet C++11 compliant.

`$ c++ --version
Apple clang version 3.1 (tags/Apple/clang-318.0.61) (based on LLVM 3.1svn)
Target: x86_64-apple-darwin11.4.0
Thread model: posix`

I also tried with GCC but I have the same problem:
`$ g++ --version
i686-apple-darwin11-llvm-g++-4.2 (GCC) 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2336.9.00)`

After a quick search, I came up with this:

http://urfoex.blogspot.com/2012/06/c11-fixing-bug-to-use-chrono-with-clang.html

There's a link to a patch....I'll just quote the page verbatim:

"""Funny thing: there is a fix to it:
http://clang.llvm.org/libstdc++4.7-clang11.patch

So I tried the following:

1. Opening the file: /usr/include/c++/4.7/type_traits
2. Going down to line 1749
3. Changing the line to what the patch said:
   { typedef typename decay<decltype(true ? declval<_Tp>() : declval<_Up>())>::type type; };"""

I'm not sure if that will fix the issue, but I wrote the library using C++11 features, the latest GCC should support all of the ones I've used. (VS2012 has the least, of the two).

[zarthcode]

Maybe there's an easy way to use boost as a substitute for missing C++11 features?

I installed gcc-4.7 and it now complains about conio.h.

Wow, after a minute of digging, it looks like conio.h is actually non-standard! I used it simply to provide a way to pause to read the output. I guess I need to pickup a mac-mini...

[zarthcode]

The conio issue should be fixed now.

[mcuee]

Thanks, now the conio issue is fixed but there are more problems. I guess the C++11 support
of gcc 4.7.1 is really experimental.

Actually, these are all issues with the C library funcitons, (as well as the exception class). Looks like the microsoft compiler allows construction of an exception with a string parameter where it probably shouldn't be ...breaking compatibility. No C++11 related errors there! (whew!)

As for the memset errors, I'm not sure why I never got an error on that. I suspect it was included as part of <wchar.h>. I've changed all references to use std::fill instead.

The strlen/strcpy methods should be in : once again there's no errors from windows helping me out here. But I believe I have ironed out all of the issues about

I may soon have some Mac hardware to test this out on so I can support this better.

[LudovicRousseau]

You can also install virtualbox and create a virtual machine with Ubuntu (or anther GNU/Linux system) inside.

Apple uses LLVM/clang instead of GCC. So you may find differences.

[mcuee]

Great, now the compiling issue is gone. But how to build the library itself? Could you provide a Makefile?
