1.3. Ports

This instructions are done inside chroot.

1.3.1. Ports Layout

Make sure follow directories exist;

	#  mkdir /usr/ports
	#  mkdir -p /usr/ports/{distfiles,packages,work,pkgbuild}

1.3.2. Build as user

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

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

You can add your self to group pkgmk. Check if members of this group are under tpe protection.

        # usermod -a -G pkgmk username

	#  chown pkgmk /usr/ports/{distfiles,packages,work,pkgbuild}
	#  chown pkgmk:pkgmk /usr/ports/pkgbuild
	#  chmod g+w /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,mode=0750 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, remove pipe from compiler flags and let the system get from nproc how many cpu's it can use for compiling;

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

        export CFLAGS="-O2 -march=x86-64"
        export CXXFLAGS="${CFLAGS}"

        export JOBS=$(nproc)
        export MAKEFLAGS="-j $JOBS"

        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=(https://hive.gnu.systems/mirror/distfiles/)
        # PKGMK_SOURCE_DIR="$PWD"
        PKGMK_SOURCE_DIR="/usr/ports/distfiles"
        # PKGMK_PACKAGE_DIR="$PWD"
        PKGMK_PACKAGE_DIR="/usr/ports/packages"
        # PKGMK_WORK_DIR="$PWD/work"
        PKGMK_WORK_DIR="/usr/ports/work/${name}"
        # PKGMK_DOWNLOAD="no"
        # PKGMK_IGNORE_SIGNATURE="no"
        # PKGMK_IGNORE_MD5SUM="no"
        # PKGMK_IGNORE_FOOTPRINT="no"
        # PKGMK_IGNORE_NEW="no"
        # PKGMK_NO_STRIP="no"
        # PKGMK_DOWNLOAD_PROG="wget"
        # PKGMK_WGET_OPTS=""
        # PKGMK_CURL_OPTS=""
        # PKGMK_COMPRESSION_MODE="gz"

        # End of file

If you want native build change the above example to;

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

Check toolchain for more options on how packages are build.

1.3.4. Configure prt-get

Edit /etc/prt-get.conf;

        ###
        ### prt-get conf
        ###

        # note: the order matters: the package found first is used
        prtdir /usr/ports/core
        prtdir /usr/ports/opt
        prtdir /usr/ports/xorg

        # the following line enables the multilib compat-32 collection
        #prtdir /usr/ports/compat-32

        # the following line enables the user maintained contrib collection
        prtdir /usr/ports/contrib
        prtdir /usr/ports/ports
        prtdir /usr/ports/mate
        prtdir /usr/ports/kde

        ### use mypackage form local directory
        # prtdir /home/packages/build:mypackage

        ### log options:
        # writelog enabled         # (enabled|disabled)
        # logmode  overwrite       # (append|overwrite)
        # rmlog_on_success yes     # (no|yes)
        logfile  /var/log/pkgbuild/%n.log
                                   # path, %p=path to port dir, %n=port name
                                   #       %v=version, %r=release

        ### use alternate cache file (default: /var/lib/pkg/prt-get.cache
        # cachefile /mnt/nfs/cache

        ### print README information:
        readme verbose           # (verbose|compact|disabled)

        ### prefer higher versions in sysup / diff
        preferhigher yes      # (yes|no)

        ### use regexp search
        # useregex no        # (yes|no)

        ### run pre- and post-installs scripts; yes is equivalent to the
        ### --install-scripts option
        runscripts yes            # (no|yes)

        ### expert section ###

        ### alternative commands
        makecommand      sudo -H -u pkgmk fakeroot pkgmk
        addcommand       sudo pkgadd
        removecommand    sudo pkgrm
        runscriptcommand sudo sh

1.3.5. Ccache and distcc

Ccache avoids same code to be compiled by saving the output from compilers and identifying same input by using hashes and distcc distributes compiling process across machines.

Don't set native or generic on /etc/pkgmk.conf.

        $ prt-get depinst ccache distcc

Add to /etc/profile;

        export PATH="/usr/lib/ccache/:$PATH"
        export CCACHE_DIR="/var/cache/ccache"
        export CCACHE_COMPILERCHECK="%compiler% -dumpversion; crux"
