Re: [Boost-users] [cfe-dev] [llvm-dev] Error: ISO C++17 does not allow 'register' storage class specifier [-Wregister], when building Boost 1.69.0
I'll build using C++14 mode, then. I wonder if Python 3.7.1 has this issue as well? If it doesn't, then maybe Boost should switch over to that version of Python. ________________________________ From: Matthieu Brucher <matthieu.brucher@gmail.com> Sent: Tuesday, December 25, 2018 2:56 PM To: Oleg Smolsky Cc: Craig Topper; Osman Zakir; clang developer list; cfe-users@lists.llvm.org; llvm-dev@lists.llvm.org Subject: Re: [cfe-dev] [llvm-dev] Error: ISO C++17 does not allow 'register' storage class specifier [-Wregister], when building Boost 1.69.0 The issue comes in part form the Python headers that have the keyword.

Python 2.7 will always have this issue. Python 3 may have fixed the issue, but Python 3 is supported by Boost.Python for a long time now. The question is which Python version you want to wrap. It seems that you don't know the Python 2 and Python 3 are different products. You may not even need to build these then. If you are using Python 2, you don't have a choice, ou have to either fix the headers or remove the error in another way.

I realize that the "why" probably doesn't help you move forth with your problem, so here are a couple suggestions how to get over it:
- Build Boost in C++14 mode with -std=c++14 - Cut out "register" from the Boost source and rebuild - Try a newer Boost version, it may have been fixed
