make failed about qtxlsxwriter

[VSRonin]

Can I ask what compiler are you using?

[zuzuviewer]

@VSRonin
GNU Make 3.82.
g++ 4.8.5 20150623 (Red Hat 4.8.5-11)

[VSRonin]

Strange that it would require C++17 standard. it should not.
Can I ask how you are building the library?

[zuzuviewer]

@VSRonin ，I follow README document's "Usage(1): Use Xlsx as Qt5's addon module" steps

[VSRonin]

Sorry to be this inquisitive, I still haven't narrowed down where the problem might be.
Would you be able to use CMake to build the project and see if that works?

[zuzuviewer]

it was work with cmake 3.9.0

[VSRonin]

This is very strange, in theory the 2 methods should be equivalent.
Thanks for bearing with me on this, hope the CMake solution is good enough

[zuzuviewer]

Yes,the CMake solution is good
