@suezhanglove - what compiler are you using ? You need c++14 support to build mapnik@master.

[suezhanglove]

zs@zs-vm:~/mapnik-3.x$ g++ -v gcc version 5.4.0 20160609 (Ubuntu 5.4.0-6ubuntu1~16.04.4)

my gcc version is 5.4.0

[artemp]

Please, try gcc6 series which have better c++14 support. apt-get update -y && apt-get install gcc-6

[suezhanglove]

Thanks a lot ! i'll try!

[suezhanglove]

fix it! i update gcc to gcc6series. it works well.But meet another problem.
