build error: clang3.8 - boost1.54 - Ubuntu 14.04.5 LTS

[FinchPowers]

Hi!

Is it supposed to build with clang or not? I saw issues and a branch related to it, so I'm unsure because on the other hand the doc only states "gcc".

So if it's not meant to work, here I have my answer. Otherwise, here is some of the errors I've got.

First, the exact compile command:

clang++-3.8 -fPIC -m64 -fno-omit-frame-pointer -msse3 -msse4.2 -Wall -Werror -Wno-sign-compare -Woverloaded-virtual -Wno-deprecated-declarations -Wno-deprecated -Winit-self -Qunused-arguments -Wno-mismatched-tags -Wno-unused-function -ftemplate-backtrace-limit=0 -pipe -ggdb -std=c++0x -fno-builtin-malloc -fno-builtin-calloc-fno-builtin-realloc -fno-builtin-free -o build/x86_64/obj/mldb/ext/casablanca/./Release/src/http/client/http_client_asio.cpp.9819bedd7c25b3339b1e1430acb29b55.lo -c ./mldb/ext/casablanca/./Release/src/http/client/http_client_asio.cpp -MP -MMD -MF build/x86_64/obj/mldb/ext/casablanca/./Release/src/http/client/http_client_asio.cpp.d -MQ build/x86_64/obj/mldb/ext/casablanca/./Release/src/http/client/http_client_asio.cpp.9819bedd7c25b3339b1e1430acb29b55.lo -O3 -DBOOST_DISABLE_ASSERTS -DNDEBUG -D_DEBUG -Imldb/ext/casablanca/Release/src/pch -Imldb/ext/casablanca/Release/include -Imldb/ext/casablanca/Release/libs -Wno-overloaded-virtual -Wno-unused-local-typedefs -Wno-unknown-pragmas -D_DEBUG -Imldb/ext/casablanca/Release/src/pch -Imldb/ext/casablanca/Release/include -Imldb/ext/casablanca/Release/libs -Wno-overloaded-virtual -Wno-unused-local-typedefs -Wno-unknown-pragmas

Then the build errors

./mldb/ext/casablanca/./Release/src/http/client/http_client_asio.cpp:44:2: error: "Cpp rest SDK requires c++11 smart pointer support from boost"
#error "Cpp rest SDK requires c++11 smart pointer support from boost"
 ^
./mldb/ext/casablanca/./Release/src/http/client/http_client_asio.cpp:1432:21: error: no matching member function for call to 'expires_from_now'
            m_timer.expires_from_now(m_duration);
            ~~~~~~~~^~~~~~~~~~~~~~~~

The output of clang++-3.8 -v is

Lastly, if I rebuild everything with g++/gcc 4.8.5 instead, the same command works.

Any help is appreciated. Thanks!

I had very similar issue with Android NDK r16b (armv7, libc++):

solved by patching Release/src/http/client/http_client_asio.cpp: replaced m_timer.expires_from_now(m_duration) via m_timer.expires_from_now(std::chrono::microseconds(m_duration.count()))
