I am trying to build software from source (specifically, Asymptote 2.66). This worked fine on Ubuntu 18.04.
But a number of the files the make file needs, such as:
- byteswap-16.h and libio.h in /usr/include/x86-64-linux-gnu/bits/
- limits.h in /usr/lib/gcc/x86-64-linux-gnu/7/include-fixed
are simply not present in Ubuntu 20.04. Well, not present in the expected locations. They can be found in /snap/gnome-3-34-1804.
Every bit of help online says to install
But all of these are installed. Other than manually copying needed files one by one, is there a way to get all the necessary files to build from source?
