Le blog de Jean David TECHER, un Réunionnais à Saint-Priest/Lyon

In this ticket I share the first tests I did for LLVM 3.9.0. Since we are in April 2016 then LLVM 3.9 is currently being developped. So it is time to test it . For my own tests I am using cmake version 2.8.12.2

root@amdgaming:~# cmake --version
cmake version 2.8.12.2

LLVM is required to play native Windows games on Linux through Wine when you use Open Source Drivers (Mesa/xf86-video-ati/Gallium Nine). I need LLVM so I can use SIScheduler (R600_DEBUG=sisched) for a couple of games to come.

Then let's go!

• Create a folder for source

  mkdir -pv /opt/Sources/llvm-3.9.0_$(date -I)
  cd /opt/Sources/llvm-3.9.0_$(date -I)

• Download latest LLVM sources and clang sources from SVN Repo

  svn co http://llvm.org/svn/llvm-project/llvm/trunk llvm
  cd llvm/tools/
  svn co http://llvm.org/svn/llvm-project/cfe/trunk clang

• It is recommended to build LLVM binairies out of llvm sources folder. We will create another folder

  mkdir -pv /opt/Builds/llvm-3.9.0_$(date -I)_build
  cd /opt/Builds/llvm-3.9.0_$(date -I)_build

• Configure LLVM using cmake

  cmake -G "Unix Makefiles" \
  	-DCMAKE_INSTALL_PREFIX=/opt/llvm/3.7.0 \
  	-DLLVM_ENABLE_ASSERTIONS=Off \
  	-DBUILD_SHARED_LIBS=ON \
  	-DCMAKE_BUILD_TYPE=Release \
  	-DLLVM_TARGETS_TO_BUILD="AMDGPU;X86" \
  		/opt/Sources/llvm-3.9.0_$(date -I)/llvm/

  Notices
  • -DCMAKE_INSTALL_PREFIX is set to /opt/llvm/3.7.0. I started my tests on LLVM for version 3.7 in 2015. Since 2015 on my Ubuntu 14.10 computer I am used to reuse the same folder to test llvm. (perhaps I should update it to /opt/llvm/3.9.0/ ?)
  • -DBUILD_SHARED_LIBS is set to ON to make life easier for Mesa when Mesa will be linked to LLVM. LLVM is built statically (unless I am wrong?)
  • -DCMAKE_BUILD_TYPE=Release avoids to get an annoying issue while ld is trying to link everything for libclang.so. We avoid the error "Memory exhausted" = not enough memory.
  • -DLLVM_TARGETS_TO_BUILD="AMDGPU;X86" are specific targets (AMDGPU support and x86 for my Linux 32 Bits). Specifying targets helps
    • to reduce targets lists and avoid to build unused targets
    • to reduce expected time to build llvm. It is well known that LLVM takes a lot of time to be built
• Build

  make -j4

• Install

  make install

Since February 2016 I maintain another web page so you can download easily latest Wine-Staging Sources repatched with Gallium Nine. Archives are available too.

• Main Web page for Wine 1.9/Mesa 11.2/Gallium Nine
• Wine-Staging sources repatched with Gallium Nine (Latest and Archived Sources). Please have a look in the table and the comments column to have a brief description.

Sources for Wine-Staging 1.9.7 and Gallium Nine are available on mediafire.com http://www.mediafire.com/download/418h06bsep1cc93/Wine-Staging-1.9.7_Gallium-Nine_Steam-Hacks.tar.bz2

I play this game since January 2016. Today I am finaly in the TOP 50 users for my playtime through 15-Feb-2016 - 21-Feb-2016. That's the first time I won something . Well 53 hours is low compared to 150 hours for the 1st one. This is not too bad . My current challenge is to play this game with limited resources (no OP weapon from DLC) Original news: http://steamcommunity.com/games/366160/announcements/detail/857178084759072510

Game works pretty well with Gallium Nine.

Prerequisites

Using Winetricks you should just have to install vcrun2005. But while I was trying to launch the installer I noticed that installer wanted to install VCRUN2015 SP1. So I stop the installation and I just run

winetricks -q vcrun2015 vcrun2005 allfonts

After that I re-launched the installer. I just installed vcrun2015 for the peace of Mind.

Tips to know

• The game is able to download sources/ update itself
• Bypassing Gameguard is not recommended compared to what I read on WineHQ WebSite for this game
