fatal error: 'chrono' file not found #2

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: So I tried the following:
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). |
|
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. mymacmini:LibusbTest xiaofanc$ g++-4.7 -I../headers LibusbTest.cpp -o LibusbTestIn file included from /usr/local/Cellar/gcc/4.7.1/gcc/lib/gcc/x86_64-apple-darwin11.4.0/4.7.1/../../../../include/c++/4.7.1/chrono:35:0, mymacmini:LibusbTest xiaofanc$ g++-4.7 -std=c++11 -I../headers LibusbTest.cpp -o LibusbTest |
|
BTW, I install gcc-4.7 using Homebrew-dupes gcc formula for my Mac (OS X Lion 10.7.4). mymacmini:LibusbTest xiaofanc$ g++-4.7 -v |
|
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... |

The conio issue should be fixed now. |
|
Thanks, now the conio issue is fixed but there are more problems. I guess the C++11 support mymacmini:LibusbTest xiaofanc$ g++-4.7 -std=c++11 -I../headers LibusbTest.cpp -o LibusbTest |

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. |

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. |
|
Great, now the compiling issue is gone. But how to build the library itself? Could you provide a Makefile? mymacmini:LibusbTest xiaofanc$ g++-4.7 -std=c++11 -I../headers LibusbTest.cpp -o LibusbTest |
|
...and here I was thinking that the library was already compiled! :-) I'll need a mac for product testing anyway, I should be able to test under every OS w/one machine then. |
std::exception has no constructor which takes a c-string as argument, this seems to be Microsoft specific.
