installing aur packages with makepkg and root execution issues

[aslakstubsgaard]

since yogurt has become depricated i'm installing openfoam from the aur with

git clone https://aur.archlinux.org/openfoam.git
cd openfoam
makepkg -si

this results in

==> Creating package "openfoam"...
  -> Generating .PKGINFO file...
  -> Generating .BUILDINFO file...
  -> Adding install file...
  -> Generating .MTREE file...
  -> Compressing package...
==> Leaving fakeroot environment.
==> Finished making: openfoam 7-1 (Mon Nov 25 18:13:21 2019)
==> Installing package openfoam with pacman -U...
error: you cannot perform this operation unless you are root.
==> WARNING: Failed to install built package(s).

while running makepkg -si in fakeroot enviroment yields

==> ERROR: Running makepkg as root is not allowed as it can cause permanent,
catastrophic damage to your system.

my way around that was subsequently running pacman -U from fakeroot

pacman -U openfoam-7-1-x86_64.pkg.tar.xz

if there's a way around this i'd like to know. but think the readme needs more of a procedure, rather then the one line now given.

also, makepkg can't install repo dependencies without fakeroot. so the procedure if i'm not missing something is

• first in junest, run git clone ... and makepkg -s to find out what repo dependencies your missing
• now in junest -f, install missing repo dependencies with pacman -S ...
• and then back in junest and the package folder, run makepkg -s to build the tar files
• finally back in junest -f, navigate back to the same folder, run pacman -U ...pkg.tar.xz

Which makepkg have used?

You need to use the one located in: /opt/makepkg/bin/makepkg

[aslakstubsgaard]

which makepkg gives /usr/bin/makepkg, but i don't have a /opt/makepkg folder. this junest installation was also initially set up over a year ago. installing a fresh junest on another system produces the /opt/makepkg folder.

the procedure then boils down to:

git clone ...
cd ...
/opt/makepkg/bin/makepkg -si

great!

recommendations on how to build the /opt/makepkg folder it on older installations?

I think this is not clear enough in the readme.
