building error on ubuntu

[godmiaozi]

i build the generated cxx files on ubuntu with g++

build cmd: g++ -std=c++14 test.cpp -Icpplib -fconcepts -o testexe

I get the following error:

is there any specific prerequisites for building the CXX files. hope can get feedbacks, thx

try to use clang 11 but I think "concepts" are not supported there yet

@ASDAlexander77 thx for your reply. i would like to ask several more questions.

• how much of the TypeScript specification has been supported?
• i have some similar idea to translate typescript into some other representations. But instead of translating typescript into C/C++, i would like to translate typescript into some bytecode format(something like java/JavaScript bytecode). Do u have any suggestion for that.
• is there any demo or tutorial which can guide me to traverse the TS AST and generate bytecode?
