Yes, same here on aarch64-linux (Debian Stretch). I had to hand in the
libglm-dev package, but just to find this later on:

g++ -Wall -DHAVE_CONFIG_H -D_FILE_OFFSET_BITS=64 -DUSEGC  -pthread
-DFFTWPP_SINGLE_THREAD  -I. -Igc-8.0.2/include -I/usr/include/tirpc
-ansi -O2 -pipe -fno-var-tracking -o shaders.o -c shaders.cc In file
included from /usr/include/c++/6/unordered_set:35:0, from
shaders.cc:8: /usr/include/c++/6/bits/c++0x_warning.h:32:2: error:
#error This file requires compiler and library support for the ISO C++
2011 standard. This support must be enabled with the -std=c++11 or
-std=gnu++11 compiler options. #error This file requires compiler and
library support \ ^~~~~ Makefile:341: recipe for target 'shaders.o'
failed make[1]: *** [shaders.o] Error 1

So I needed to change the "CXXFLAGS=-ansi" to
"CXXFLAGS=-std=c++11" (from the “Special considerations for asymptote”
section of http://tug.org/texlive/build.html ). Now it builds and
passes all its tests. Whatever that means for those pitiful platforms
where we don't have C++11.

Best,
Johannes
