peglib.hpp is a header-only library used to generate parsers with peg syntax. It takes 34 seconds to compile main.cpp which includes said header, which is why im trying to precompile peglib.hpp
Command used to precompile header:
g++ peglib.hpp
Compile main.cpp:
g++ -H main.cpp -o main
However, compilation time does not change. It is noted that peglib.hpp and peglib.hpp.gch are in the same directory. No ! or x; precompiled header isn't even detected with -H option.
Some info:
peglib.hpp requires c++17.
main.cpp includes the header but does not use it, only returns 0 from main.
Im using Termux with clang version 17.0.6 on android 9 arm.
I installed an ubuntu distro and it worked fine, looks like its a Termux problem
