# This file is used by Portage to customise your packages.
# Check the manual page for make.conf or the gentoo wiki for more flags.

# These flags are used by your PC's C, C++, and Fortran compilers.
# In this file, all these compilers will use the same flags.
# --march=native will compile all packages for your PC's architecture, 
#    ensuring nothing is ever cross-compiled.
# -O2 means our compiler will try and optimise code during compilation.
#    It's not recommended to go to -O3 for all packages, so we'll go
#    with the -O2.
# -pipe dictates how different stages of compilation communicate.
#    -pipe means use pipes instead of temporary files.

# Defines additional software licenses for us to use.
# I am trying to use more FOSS software, so I only want to packages that Gentoo considers free software.
# The '-*' means 'only use the following licenses'
# Even if this causes problems, I can add exceptions for problematic packages.
ACCEPT_LICENSE="-* @FREE linux-fw-redistributable no-source-code"

# Recent packages are on 'testing' branches. This variable sets the testing branch we'll use for packages.

# MAKEOPTS determines how many parallel compilations should occur when
# installing a package. It's usually not worth making this higher than the
# number of available CPUs.
# For example, I am using an AMD 7950X, which has 16 cores and 2 threads per core, for a toral of 32 available processes.
# -j is the number of processes to run in parallel.
# -l is the maximum allowed load average, which should be about j*0.9
MAKEOPTS="-j32 -l28.8"
# Similar story with this one

# This is used to tell Portage what graphics card you are using (if any).
# Your choices are:
# * 'amdgpu radeonsi' for newer open-source amd drivers

# * 'nvidia' for the proprietary nvidia drivers
# * 'radeon radeonsi' for older open-source amd drivers

# Portage uses the USE variable to determine the default way to build
# a package. You can add/remove flags using the USE variable in this file.
# NOTE: This does not overwrite the value of USE that Portage uses, it only
# appends to it! It also applies to ALL packages you build, so only
# put a flag here if you want it to apply system-wide!
#  alsa:       Add support for the advanced linux sound architecture.
#  bluetooth:  Add bluetooth support
#  elogind:    Build packages that normally require logind from systemd.
#  examples:   Download code examples where applicable.
#  ffmpeg:     Enable certain kinds of audio/video codec support.
#  ipv6 :      Add support for ipv6.
#  multilib:   Allow compilation of 32-bit binaries.
#  opengl:     Add support for openGL graphics.
#  pipewire:   Add pipewire support
#  pulseaudio: Add support for pulseaudio.

#  udev:       Enable virtual/udev integration.
#  vaapi:      Video stuff.
#  vdpau:      Video stuff.
#  vulkan:     Build in Vulkan driver support.
#  wayland:    Add support for Wayland.
#  X:          Although I am using Wayland, some packages use this flag to add xwayland support.
#  xwayland:   Same story.
#  -emacs:     Don't add support for emacs.
#  -gnome:     Don't add GNOME support.
