1.3. Ports

This instructions are done inside chroot.

1.3.1. Build as user

For more information read Fakeroot Ports. Add a user that will be used by ports tools, this example pkgmk;

        # useradd -U -M -d /usr/ports -s /bin/false pkgmk

You can add your self to group pkgmk, Members of this group will not be under tpe protection.

        # usermod -a -G pkgmk c9admin

        # chmod -R 774 /usr/ports
        # chmod 775    /usr/ports

1.3.2. Ports Layout

This configuration will build and save files inside home directory of the user pkgmk. Work directory will be mounted on ram to speed up the build process and added to fstab. Let's start by creating layout directories

        # sudo -u pkgmk mkdir /usr/ports/distfiles
        # sudo -u pkgmk mkdir /usr/ports/packages
        # sudo -u pkgmk mkdir /usr/ports/work
        # sudo -u pkgmk mkdir /usr/ports/pkgbuild

Configure to compile in ram average of 3GB is recommended for core while firefox need at least 30G. Discover id of pkgmk user;

        # id pkgmk
        uid=102(pkgmk) gid=102(pkgmk) groups=102(pkgmk)

Edit fstab, change uid to id of pkgmk, this example 102;

        pkgmk /usr/ports/work tmpfs size=30G,uid=102,defaults 0 0

1.3.3. Configure pkgmk

Read 4.5. Adjust/Configure the Package Build Process to take advantage of your specific hardware. Packages build with native flag will not run on different hardware. This is the best choice if you want gcc to find the best settings based on your hardware.

Edit /etc/pkgmk.conf and remove pipe from compiler flags;

        export CFLAGS="-O2 -march=x86-64"

If you want native build change the above example to;

        export CFLAGS="-O2 -march=native -mtune=native"

"-protector-strong" which only insert stack canaries in fuctions where overflow might actually happen

Discover number of cores/cpus to hard code -j option.

        $ nproc
        2

Set number of cores to use;

        export MAKEFLAGS="-j2"

Example of complete pkgmk.conf for x86_64 with 4 cores, separate distribution files, packages and work directories, uses crux mirror to get the sources.

        #
        # /etc/pkgmk.conf: pkgmk(8) configuration
        #

        export CFLAGS="-O2 -march=native -mtune=native"
        export CXXFLAGS="${CFLAGS}"

        export MAKEFLAGS="-j4"

        case ${PKGMK_ARCH} in
                "64"|"")
                        ;;
                "32")
                        export CFLAGS="${CFLAGS} -m32"
                        export CXXFLAGS="${CXXFLAGS} -m32"
                        export LDFLAGS="${LDFLAGS} -m32"
                        export PKG_CONFIG_LIBDIR="/usr/lib32/pkgconfig"
                        ;;
                *)
                        echo "Unknown architecture selected! Exiting."
                        exit 1
                        ;;
        esac

        #PKGMK_SOURCE_MIRRORS=(http://crux.nu/distfiles/)
        PKGMK_SOURCE_DIR="/usr/ports/distfiles"
