Re: [Hol-info] hol4 relocatable build

SourceForge Headquarters 1320 Columbia Street Suite 310 San Diego, CA 92101 +1 (858) 422-6466

Dear Mark,

This (HOLDIR being hardcoded) is a known (but previously undocumented
outside of private emails) issue.
I have created an issue for it, and some of the discussion about how to fix
it and hard problems:
  https://github.com/mn200/HOL/issues/105
I am also interested in making HOL4 installable after building so I can
make a package for Parabola (and Arch Linux).

Your second issue about executable stack markings I'm less familiar with.
Have you submitted your polyml patch upstream?
What is the right way to fix it? Do we just need -Wa,--noexecstack to be
passed at all times to poly during the build?
Is it suitable for non-GNU-based systems? Perhaps I leave this one for you
to sort out by patching for Gentoo.
I guess you need help tracking down other ways in which executables are
created during the build process? (It might be a bug that machine_flags
doesn't catch them all.)

Cheers,
Ramana
