Re: [Boost-users] [type traits] Using Boost.Geometry with Clang/LLVM & VC14

Hi Ernest, The boost build is with plain VC14 (bootstrap, without any hacking whatsoever), not clang (that's no problem). The RC1 build is fine, the trouble is later on in the headers, when using Clang. When I try to build my app (with GGL), the previously reported errors show up, both with 1.61 and 1.60. The problem is not in GGL, but in type_traits (and typeof, but that seems to be fixed, ready for merging). Have a good day, degski On 20 March 2016 at 11:15, Ernest Zaslavsky wrote:

Hi,

Did you build it using boost bootstrapping or you have to do some “hacks”?

Does your experience apply to 1.61 RC or 1.60 too?

I've successfully compiled Boost 1.61.0 Beta 1 Release Candidate with VC14 (no Clang-Cl.exe) in debug and release.

This has exposed the "hacks" I mentioned earlier in this thread. When compiling my test program with Clang-Cl (latest) and VC14, the following errors are reported. (in my hacks I just added std:: to the boost code in the appropriate places, untill Clang stopped complaining.

Then there are more errors, but they are either the same as the ones I've reported earlier, or the result of the above errors.

Have a good day,
