Compile PARI to OUT_DIR and statically link to it (before the build script was trying to install things system wide).
Move all PARI files into a non-versioned directory called pari so that PARI can be upgraded without changing build script.
Stop rebuilding PARI on every compilation by only rebuilding when pari/CHANGES changes.
Add .gitignore which attempts to ignore things PARI creates during the build

Brilliant !

Before merging - lets say there is new PARI version. What are the steps required to update?

LLFourn commented 4 years ago

I'd say this is the best way to go about it:

comment out lines under pari/ in .gitignore
replace pari directory with new pari version and stage pari/ directory.
cargo build
add lines back to .gitignore as needed to ignore all the pari build artefacts until workspace is clean
commit new pari/ directory and .gitignore.
