chrono failed to build on MacOsX Yosemite 10.10.5 with Clang about chrono

[hmazhar]

Hi Vincent,

Clang hasn’t been tested with chrono, I usually use OSX home-brew and "brew install gcc”
The gcc compilers work on OSX, if clang is a requirement please let me know and I can work on fixing the problems.

Thanks,
Hammad

Hi Hammad,

Ok, I'll switch to gcc for a while and try to fix the issue with clang later.

Thanks,
Vincent.

[andrewseidl]

Try building the latest from the develop branch with Clang. The code in tag 2.0.0 is almost two years old at this point.

[vacary]

Thanks for the advice.

Unfortunately, I got the same error. I will switch to gcc

[andrewseidl]

It still looks like you're on an out of date version of Chrono: some of the compiler options in there were removed/changed about a year ago, and the sources have been reorganized in the last couple of weeks.

git checkout develop && git pull and check the date of the most recent commit via git log -1 (it should be from today or yesterday).

It builds fine for me with Clang on 10.10.5, no GCC.

[vacary]

This is fixed. Thank you very much and sorry for the noise.
I was on the master branch...
Cheers
