when i open hls project with vivado hls，i set synthesis section'cflags -std=c++0x in hls project settings dialog,it's compiler ok，I want to know how to pass parameters std=c++0x or -std=gnu++0x compiler options to into synthesis section'cflags in hls project settings dialog by gcc/v++ commands on accelerate platform design,There seems to be no relevant parameters here, g++ -Wall -g std=c++0x..... has no effect,it not pass parameters std=c++0x or -std=gnu++0x compiler options to into synthesis section'cflags in hls project

/opt/Xilinx/Vivado/2019.2/lnx64/tools/gcc version is 4.6.3 , Should this be upgraded to version 4.8.x? Because I learned from the information that the c++11 feature is fully supported after the version of compiler gcc 4.8.x,how to upgraded /opt/Xilinx/Vivado/2019.2/lnx64/tools/gcc version to 4.8.x?

2019.2 means a version of year 2019, which is very old. If you get a version 2022.1 for example, you will get a more modern tool chain, supporting C++14 and some C++17.
