yuzu-wiki/Building-for-Linux.md

Dependencies:

You'll need to download and install the following to build yuzu:

• SDL2
  • Deb: apt-get install sdl2 or apt-get install libsdl2-2.0-0 or apt-get install libsdl2-dev
  • Arch: pacman -S sdl2
  • Fedora: dnf install SDL2-devel
  • Gentoo: emerge media-libs/libsdl2
• Qt
  • Deb: apt-get install qtbase5-dev libqt5opengl5-dev
  • Arch: pacman -S qt5
  • Fedora: dnf install qt5-qtbase qt5-qtbase-devel
  • Gentoo: emerge dev-qt/qtcore dev-qt/qtopengl
• GCC v5+ (for C++14 support)
  • Deb: apt-get install build-essential
  • Arch: pacman -S base-devel
  • Fedora: dnf install sys-devel/gcc
• CMake 3.6+
  • Deb: apt-get install cmake
  • Arch: pacman -S cmake
  • Fedora: dnf install cmake
  • Gentoo: emerge dev-util/cmake
• Clang 3.8 (optional build alternative)
  • Deb: apt-get install clang libc++-dev (in some distros, clang-3.8).
  • Arch: pacman -S clang, libc++ is in the AUR. Use pacaur or yaourt to install it.
  • Gentoo: emerge sys-devel/clang sys-libs/libcxx
• Curl
  • Deb: apt-get install libcurl4-openssl-dev
  • Arch: pacman -S libcurl-compat
  • Gentoo: emerge net-misc/curl

Cloning yuzu in Git:

git clone --recursive https://github.com/yuzu-emu/yuzu
cd yuzu

The --recursive option automatically clones the required Git submodules too.

Building unicorn:

cd externals
git clone https://github.com/yuzu-emu/unicorn
cd unicorn
UNICORN_ARCHS=aarch64 ./make.sh
export UNICORNDIR=$(pwd)
cd ../..

For platforms which use python3 by default, you manually have to configure UNICORN_QEMU_FLAGS before running ./make.sh. Example: UNICORN_QEMU_FLAGS="--python=/usr/bin/python2" UNICORN_ARCHS=aarch64 ./make.sh

Building yuzu in Debug Mode (Slow):

Using gcc:

mkdir build && cd build
cmake ../ -DUSE_SYSTEM_CURL=1
make
sudo make install

Optionally, you can use "cmake -i .." to adjust various options (e.g. disable the Qt GUI).

Using clang:

Note: It is important you use libc++ vs. , otherwise your build will likely fail. libc++ is not 100% complete on GNU/Linux, but works well for this build. The libstdc++ std::string is a different data structure than the libc++ std::string. See: LLVLM.org. If libc++ is not used, some warnings are treated as errors. Using clang is only really recommended for users not using GCC >= 5. Also see Clang Comparison.

mkdir build && cd build
cmake  -DCMAKE_CXX_COMPILER=clang++-3.8 \
	-DCMAKE_C_COMPILER=clang-3.8 \
	-DCMAKE_CXX_FLAGS="-O2 -g -stdlib=libc++" \
        -DUSE_SYSTEM_CURL=1  ..
make
sudo make install (currently doesn't work, needs to be fixed)

Debian/Ubuntu: Owing to bug #808086 the build might fail. To have it build, add the following after line 1938 of /usr/include/c++/v1/string. (see discussion on StackOverflow for more details.)

#if _LIBCPP_STD_VER <= 14
    _NOEXCEPT_(is_nothrow_copy_constructible<allocator_type>::value)
#else
    _NOEXCEPT
#endif

Additionally, on Ubuntu, do sudo apt-get install libc++abi-dev && sudo ln -s /usr/include/libcxxabi/__cxxabi_config.h /usr/include/c++/v1/__cxxabi_config.h

Building yuzu in Release Mode (Optimized):

mkdir build && cd build
cmake .. -DCMAKE_BUILD_TYPE=Release -DUSE_SYSTEM_CURL=1
make
sudo make install (currently doesn't work, needs to be fixed)

Building with debug symbols:

cmake .. -DCMAKE_BUILD_TYPE=RelWithDebInfo -DUSE_SYSTEM_CURL=1
make

Running without installing:

After building, the binaries yuzu and yuzu-qt (depending on your build options) will end up in build/src/<binary_name>/.

# SDL
cd build/src/yuzu/
./yuzu

# Qt
cd build/src/yuzu_qt/
./yuzu-qt

Debugging:

cd data
gdb ../build/src/yuzu_qt/yuzu-qt
(gdb) run
<crash>
(gdb) bt
