boost-errors when compiling library
bgewehr opened this issue · 7 comments
Hi!
I want to use this library for making the ems-collector able to send and receive MQTT.
The compiler throws errors like this:
MqttAdapter.cpp:41:22: required from here
/usr/include/boost/multi_index/composite_key.hpp:460:53: error: no match for call to ‘(const std::less<short unsigned int>) (const std::tuple<short unsigned int, unsigned char>&, short unsigned int)’
if(comp.get_head()(vc.get_head(),c.get_head()(v)))return true;

I have discussed the issue with the author of ems-collector, but without success:
maniac103/ems-collector#18
Can you give me the right hint to resolve that?
My -std=c++14 was on -std=c++1y and that did not cause the errors. Still investigating.
It seems that the error is caused by https://svn.boost.org/trac/boost/ticket/10315
It is fixed as boostorg/multi_index@6d6bb75
Which version of the boost library are you using? If it is 1.55 or older, please update 1.57 or newer.
The standard library is 1.55 in Debian Linux
https://packages.debian.org/jessie/libboost-all-dev
Thanks, redboltz. I'll update my readme accordingly. It would be great if you could update your readme to list the requirements of boost 1.57 and c++14 (which isn't bitfield only anymore, it's also required for auto in lambda parameters).
Compile worked with c++1y also
@maniac103 , I updated README.md. Also I removed generic lambda from the library code.
I close the issue. Thank you for your cooperation.
If there are any problems, please reopen the issue.
I can confirm the library compiles fine again with GCC and -std=c++0x. Thanks!
