<h2 id="filesystem">1.4.1. Ports Layout</h2>
<p>Make sure follow directories exist;</p>
<pre>
# mkdir /usr/ports
# mkdir -p /usr/ports/{distfiles,packages,work,pkgbuild}
</pre>
<h2 id="fakeroot">1.4.2. Build as user</h2>
<p>For more information read
<a href="https://crux.nu/Wiki/FakerootPorts">Fakeroot Ports</a>.
Add a user that will be used by ports tools, this example pkgmk;</p>
<pre>
# useradd -r -U -d /usr/ports -s /bin/false pkgmk
</pre>
<p>You can add your self to group pkgmk. Check if members of this
group are under <a href="linux.html#sysctl">tpe</a> protection.</p>
<pre>
# usermod -a -G pkgmk username
</pre>
<pre>
# chown pkgmk /usr/ports/{distfiles,packages,work,pkgbuild}
# chown pkgmk:pkgmk /usr/ports/pkgbuild
# chmod g+w /usr/ports/pkgbuild
</pre>
<p>Configure to
<a href="https://crux.nu/Wiki/HowToSpeedUpBuildingPackages#ram">compile in ram</a>
average of 3GB is recommended for core while firefox need at least 30G.
Discover id of pkgmk user;</p>
<pre>
# id pkgmk
uid=102(pkgmk) gid=102(pkgmk) groups=102(pkgmk)
</pre>
<p>Edit fstab, change uid to id of pkgmk, this example 102;</p>

<h2 id="pkgmk">1.4.3. Configure pkgmk</h2>
<p>Read <a href="https://crux.nu/Handbook3-3#ntoc22">4.5. Adjust/Configure the Package Build Process</a>
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.</p>
<p>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;</p>
<pre>

<p>Check <a href="toolchain.html">toolchain</a> for more options on how packages

<h2 id="prtget">1.4.4. Configure prt-get</h2>
<p>Edit /etc/prt-get.conf;</p>

###
### 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/kde5
### 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 /usr/ports/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

<h2 id="distcc">1.4.5. Ccache and distcc</h2>
<p>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.</p>
<p>Don't set native or generic on /etc/pkgmk.conf.</p>
<pre>
$ prt-get depinst ccache distcc
</pre>
<p>Configure pkgmk and define number of cores available,
in this example get dynamically Edit
<a href="conf/pkgmk.conf">/etc/pkgmk.conf</a> and
set ccaching directory and instructs to use distcc
backend;</p>
<pre>
# ccache settings
export PATH="/usr/lib/ccache/:$PATH"
export CCACHE_DIR="/usr/ports/ccache"
export CCACHE_PREFIX="distcc"
export CCACHE_COMPILERCHECK="%compiler% -dumpversion; crux"
</pre>
<p>Set distcc hosts and respective number of
cpu cores to send work, hosts names, exp; "worker" must
be configured on /etc/hosts.</p>
<pre>
### compile using distcc without ccache
##export PATH="/usr/lib/distcc/:$PATH"
##export DISTCC_HOSTS="localhost/4,lzo,cpp xborg/4,lzo,cpp"
