[pacman-dev] [Usage] run pacman without root
by nly＠disroot.org 08 Jan '20

08 Jan '20

Is it possible to use pacman without root, and locally, say `~/pacman` instead of global `/usr'. I built and installed pacman from git sources. $ cd pacman && git checkout v5.2.1 $ autoreconf -vif $ ./configure --prefix=$HOME/pacman/usr/local --enable-static --with-libcurl --with-gpgme $ make $ make install Adding pacman to path, `.bashrc': source /home/nly/pacman/usr/local/etc/profile # (4.) $ pacman -Q nano warning: database file for 'core' does not exist (use '-Sy' to download) error: package 'nano' was not found $ pacman -Sy error: you cannot perform this operation unless you are root. I've linked to the etc/pacman.conf (3.) and etc/pacman.d/mirrorlist (2.). Thanks, Amar ---------------- 1. makepkg-conf: http://nly.info.tm/pacman/makepkg.conf 2. mirrorlist: http://nly.info.tm/pacman/mirrorlist 3. pacman-conf: http://nly.info.tm/pacman/pacman.conf 4. bash-profile: http://nly.info.tm/pacman/profile

[pacman-dev] [Build-Requirement] In configure.ac 'File3.8' with Seccomp is required.
by nly＠disroot.org 08 Jan '20

08 Jan '20

Steps: # Checkout source git clone <pacman-git> cd pacman git checkout v5.2.1 # Build <setup the build env> autoreconf -vif && ./configure --> Fail configure fails to find the latest versoin, 3.8, of `file'. This version 3.8 of `file' is not even available in the official Arch packages. Is it possible to build with an earlier version of `file'? File version 3.8 was released about a month ago. thanks, Amar
