Hello,

  Not strictly a fedora devel question but I’m hoping all the experience and 
knowledge will be able to help. I need a newer poppler in epel 7. I’ve managed 
to bring it up to 0.68. However moving past that results in a compilation 
error. It seems the compiler (?) needs to support the c++14 standard. I’m using 
devtoolset-8 to get gcc 8.3.1 and from what I can find via google, this really 
should support c++14 (in this case std::string_literals). However when it 
compiles it sets the std to c++1y which was an alias for the draft of c++14 
from what I can gather. If I go into a mock shell however and manually run it 
with --std=c++14 it still fails. When I grep through the includes for each it 
seems both have definitions for them but it still fails. Can anyone supplement 
what I have wrong here? Should c++ 8.3.1 be able to handle 
std::string_literals? It somewhat confuses me that people are talking about the 
compiler and not some library supporting it. Any pointers/help would be 
appreciated. Here’s a snippet of the build log.

Thanks in advance for anyone able to shed some light on this for me.
