When compiling with clang++-6.0.1 I saw the error message expose: ```build/include/botan/tls_record.h:23:14: fatal error: 'tr1/functional' file not found ``` I opened the sources and found out that there code was in deal (from include/botan/tls_record.h): ``` #if defined(BOTAN_USE_STD_TR1) #if defined(BOTAN_BUILD_COMPILER_IS_MSVC) #include <functional> #else #include <tr1/functional> #endif #elif defined(BOTAN_USE_BOOST_TR1) #include <boost/tr1/functional.hpp> #else #error "No TR1 library defined for use" #endif ``` So, when compiling with clang++, it selects BOTAN_USE_STD_TR1 and _NOT_ BOTAN_BUILD_COMPILER_IS_MSVC so trying to include 'tr1/functional' that doesn't exist when clang++ is on Could we fix the issue? Thank you

The problem is not Clang itself but rather libc++, which does not support TR1. Clang with libstdc++ works fine. The easiest resolution is likely to simply disable the SSL/TLS code in the 1.10 ebuild. This is appropriate anyway as 1.10 only supports SSLv3 and TLS 1.0 both of which are broken at a protocol level. This can be done by adding `--disable-modules=ssl` to the configure.py invocation. I will send a PR for that via github. FYI Botan 1.10 is completely EOL at the end of this year, and only security issues are being addressed. We stopped patching functionality bugs in this branch 2 years ago. It looks like the only dependency in portage that still requires 1.10 is Qt Creator.
Thank you Jack Yes, you have been absolutely right I put the flag '-stdlib=libstdc++' and with c++03 standard it got compiled and linked So, also I noticed the application of this version not be built with >= c++11 standard I am wondering how we can make qt-creator maintainers switch to a newer version of botan, is it possible? Thank you
I am closing the issue. I would readdress it to a 'dev-qt' team; will try to make them switch to a newer botan I am really grateful to you for the support given
