1. libdrm編譯

# 下載
git clone http://anongit.freedesktop.org/git/mesa/drm.git
cd drm
git checkout -b libdrm-2.4.60 libdrm-2.4.60

# 依賴
sudo apt-get install libpciaccess-dev
sudo apt-get install xutils-dev

# 編譯
./autogen.sh
./configure
make
make install

2.1 問題1 dpkg

問題：

make: dpkg-architecture: Command not found

處理方法：

sudo apt-get install dpkg-dev

2.2 問題2 dri3proto

問題：

checking for DRI3PROTO... no
configure: error: Package requirements (dri3proto >= 1.0) were not met:

No package 'dri3proto' found

臨時處理方法：
修改debian\rules中

  ifeq ($(DEB_HOST_ARCH_OS), linux)
#   confflags_DRI3 = --enable-dri3

2.3 問題3 libdrm

問題：

configure: error: Package requirements (libdrm_intel >= 2.4.60) were not met:

Requested 'libdrm_intel >= 2.4.60' but version of libdrm_intel is 2.4.52

解決辦法（不需要）：

export PKG_CONFIG_PATH=/opt/candidates/lib/pkgconfig/

2.4 問題4 vdpau

問題：

checking for VDPAU... no
configure: error: Package requirements (vdpau >= 0.4.1) were not met:

No package 'vdpau' found

處理方法：修改debian\rules中

#   confflags_GALLIUM += --enable-vdpau

2.5 問題5 wayland

問題：

checking for WAYLAND... no
configure: error: Package requirements (wayland-client >= 1.2.0 wayland-server >= 1.2.0) were not met:

No package 'wayland-client' found
No package 'wayland-server' found

處理方法：

sudo apt-get install libwayland-dev-lts-trusty 

2.6 問題6 mir

問題：

checking for MIR... no
configure: error: Package requirements (mir-client-platform-mesa-dev) were not met:

No package 'mir-client-platform-mesa-dev' found

處理方法：修改debian\rules中

# Mir isn't built on AArch64 and PPC
#    ifeq (,$(filter $(DEB_HOST_ARCH),arm64 powerpc ppc64 ppc64el))
#   EGL_DISPLAYS += mir
#    endif

2.7 問題7 llvm 3.6

../../configure: line 23842: llvm-config-3.6: command not found
../../configure: line 23843: llvm-config-3.6: command not found
../../configure: line 23844: llvm-config-3.6: command not found
../../configure: line 23611: llvm-config-3.6: command not found

../../configure: line 23873: test: : integer expression expected
../../configure: line 23878: llvm-config-3.6: command not found

解決方法1：繞過

#  ifeq (,$(filter $(DEB_HOST_ARCH), s390 s390x))
#    DRI_DRIVERS += r200 radeon
#    GALLIUM_DRIVERS += r600 r300
#  endif

#  ifneq (,$(filter $(DEB_HOST_ARCH),amd64 i386 kfreebsd-amd64 kfreebsd-i386 armhf))
#   GALLIUM_DRIVERS += radeonsi
#   confflags_GALLIUM += --enable-gallium-llvm
#   confflags_GALLIUM += ac_cv_path_LLVM_CONFIG=llvm-config-3.6
#  endif

解決方法2 ：安裝llvm 3.6

sudo vi /etc/apt/sources.list

# add
deb http://llvm.org/apt/precise/ llvm-toolchain-precise-3.6 main
deb-src http://llvm.org/apt/precise/ llvm-toolchain-precise-3.6 main

# key
wget -O - http://llvm.org/apt/llvm-snapshot.gpg.key|sudo apt-key add -

再遇到問題（解決方法2）：

The following packages have unmet dependencies:
 llvm-3.6 : Depends: llvm-3.6-runtime (= 1:3.6.2~svn240577-1~exp1) but it is not going to be installed
            Depends: libllvm3.6 but it is not going to be installed
            Depends: libstdc++6 (>= 4.9) but 4.6.3-1ubuntu5 is to be installed
            Recommends: llvm-3.6-dev but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

解決辦法：

deb http://ppa.launchpad.net/ubuntu-toolchain-r/test/ubuntu precise main 
deb-src http://ppa.launchpad.net/ubuntu-toolchain-r/test/ubuntu precise main
