Re: Which C++ language version?
Oha. Learned something new. I will try this! I think we should work in the direction of the standard guideline that is published by Barne Stourstupe. That will lead us to c++11. I think that will prepare us for the future. We move slowly anyway. Am 26.

That version is not listed here: https://gcc.gnu.org/projects/cxx-status.html Under the C++98 section it does mention that the 2003 modifications are supported with -std=c++98 and -std=gnu++98. That version is also not listed in the clang documentation. - To unsubscribe, e-mail: dev-unsubscr...@openoffice.apache.org For additional commands, e-mail: dev-h...@openoffice.apache.org

I think we are depending on some GNU extensions to C++98, so our code is not strictly C++98 compliant. Try -std=gnu++98. That's what I switched to in the FreeBSD port when clang was upgraded and changed its default C++ version from C++98 + extensions to C++14. Some of our code is definitely not compliant to C++14 or newer. Our code compiles with -std=gnu++98, and I think that -std=c++0x and -std=c++11 may work as well. Some of the errors with -std=c++14 are easily fixable, but not all. I think there are some places in the code where fixing it for -std=c++14 would break it for -std=gnu++98. That doesn't mean that we can use all C++11 features. We are confined to the subset of C++0x implemented by the version of gcc in CentOS 6 (see https://gcc.gnu.org/gcc-4.4/cxx0x_status.html and read the warnings), as well as whatever is is implemented by the version of the Windows toolchain that we use. - To unsubscribe, e-mail: dev-unsubscr...@openoffice.apache.org For additional commands, e-mail: dev-h...@openoffice.apache.org

Don't we use C++ 2003?

Re: Which C++ language version?
I had to build with -std=c++11 on gcc 7. C++98 did not work as far as I remeber. C++17 did lead also to failure I believe. So I think we use features from the partial support already. Am 26.

Which C++ language version?
What version of the C++ standard should we code to? For example, can the move to STL use features that were added in C++ 11? - To unsubscribe, e-mail: dev-unsubscr...@openoffice.apache.org For additional commands, e-mail: dev-h...@openoffice.apache.org
