实验室老师让调试一个DeepLearning的程序，叫做DropConnecte,必须要在64bit的Linux系统上运行，还要配置CUDA，本人比较笨，重装了好多次Ubuntu之后才整成功，特把整理的资料发到这里
1，动态链接库解决方案http://blog.csdn.net/aquakguo0he1/article/details/9764063

一,安装python依赖包
sudo apt-get update
sudo apt-get install python-dev
sudo apt-get install python-numpy
sudo apt-get install python-magic
sudo apt-get install python-matplotlib
sudo apt-get install libatlas-base-dev
二，安装boost
sudo apt-get install libboost-dev
三，安装各种依赖包
sudo apt-get install freeglut3-dev build-essential libx11-dev libxmu-dev libxi-dev libgl1-mesa-glx libglu1-mesa libglu1-mesa-dev
附 ：
在安装cuda samples的时候需要一个贡献库文件libglut.so，默认没有安装，在终端下输入：
sudo apt-get install freeglut3
这个共享库对于32位的Ubuntu被安装在/usr/lib/i386-linux-gnu/libglut.so.3，而对于64位的Ubuntu被安装在 /usr/lib/x86_64-linux-gnu/libglut.so.3，但cuda默认会去寻找/usr/lib/libglut.so，因此我们还需要加一个软链接：
对于64位系统，在终端下输入：
sudo ln -s /usr/lib/x86_64-linux-gnu/libglut.so.3 /usr/lib/libglut.so
四，将原有驱动加入黑名单
gedit /etc/modprobe.d/blacklist.conf
blacklist amd76x_edac
blacklist vga16fb
blacklist nouveau
blacklist rivafb
blacklist nvidiafb
blacklist rivatv
五，卸载原有驱动
sudo apt-get remove --purge nvidia*
六，Xwidows操作安装驱动
sudo service lightdm stop
chmod +x。。。。。
七，安装cudatoolkit
cd /media/Work/ubuntu/cudainstallfile
sudo chmod +x cudatoolkit_4.2.9_linux_64_ubuntu11.04.run
sudo cudatoolkit_4.2.9_linux_64_ubuntu11.04.run
八，修改配置文件
gedit ～/.bashrc
1，在bashrc文本末尾添加如下内容：
export PATH=/usr/local/cuda/bin:$PATH
export LD_LIBRARY_PATH=/usr/local/cuda/lib64:$LD_LIBRARY_PATH
export LD_LIBRARY_PATH=/usr/lib/nvidia-current:$LD_LIBRARY_PATH
export CUDA_ROOT=/usr/local/cuda/bin
2，在sudo gedit /etc/ld.so.conf添加
/usr/local/cuda/lib64
/lib
九，安装SDK
cd /home/laonan/NVIDIA_GPU_Computing_SDK/C
sudo make
测试安装是否成功
cd /home/laonan/NVIDIA_GPU_Computing_SDK/C/bin/linux/release
十，常见问题解决
1,编译时若是出现类似这样的问题：
/usr/bin/ld: cannot find -lXi
/usr/bin/ld: cannot find -lXmu
/usr/bin/ld: cannot find -lglut
collect2: ld returned 1 exit status
是表示有一些必要的 Library 没装，用 apt-cache 找一下再用 apt-get 装起来就可以了：
apt-get install libxi-dev libxmu-dev libglut3-dev
2,若出现
/usr/bin/ld: cannot find -lcuda
collect2: ld returned 1 exit status
或
/usr/bin/ld: cannot find -lGL
collect2: ld returned 1 exit status
是表示找不到 NVIDIA GL 或 CUDA Library，若是您是使用 Ubuntu 内建的驱动程式管理介面安装的 NVIDIA Driver，则将 /usr/lib/nvidia-current 下面的 so 档件一个连结到 /usr/lib 下面即可：
sudo ln -s /usr/lib/nvidia-current/libcuda.so /usr/lib/libcuda.so
sudo ln -s /usr/lib/nvidia-current/libGL.so /usr/lib/libGL.so
3,解决分辨率变低的问题
（1）sudo apt-get install v86d
（2）gksu gedit /etc/default/grub
enter your password when asked and hit the Enter key.
- Replace the following line (line number 9):
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
with this one:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset video=uvesafb:mode_option=1280x1024-24,mtrr=3,scroll=ywrap"
- Replace the following line (line number 18):
#GRUB_GFXMODE=640x480
with this one:
GRUB_GFXMODE=1280x1024
save the file and close it!
（3）gksu gedit /etc/initramfs-tools/modules
When the text window appears, add the following line at the end of the file:
uvesafb mode_option=1280x1024-24 mtrr=3 scroll=ywrap
（4）
echo FRAMEBUFFER=y | sudo tee /etc/initramfs-tools/conf.d/splash
you will get right result like this：FRAMEBUFFER=y
（5）sudo update-grub2
（6）sudo update-initramfs -u
第二种解决分辨率的方法
编辑 gedit /etc/X11/xorg.conf
Section "Device"
Identifier "Configured Video Device"
EndSection
Section "Monitor"
Identifier "Configured Monitor"
Horizsync 30-81
Vertrefresh 56-75
EndSection
Section "Screen"
Identifier "Default Screen"
Monitor "Configured Monitor"
Device "Configured Video Device"
SubSection "Display"
Modes "1024x768" "1152x864"
EndSubSection
EndSection
如果你的xorg.conf编写不正确，导致进不了桌面，请在开机的时候选择recovery mode进入，以root身份登陆文本界面，输入：
rm /etc/X11/xorg.conf
这个命令会删除掉xorg.conf文件
问题三：undefined reference to `gluErrorString'
1) change the order for all occurrences of RENDERCHECKLIB in BOTH /C/common/common.mk and /CUDALibraries/common/common_cudalib.mk like this:
OLD:
LIB += ${OPENGLLIB} $(PARAMGLLIB) $(RENDERCHECKGLLIB) ${LIB} -ldl -rdynamic
NEW:
LIB += $(RENDERCHECKGLLIB) ${OPENGLLIB} $(PARAMGLLIB) ${LIB} -ldl –rdynamic
and add -L../../../C/lib in common_cudalib.mk RENDERCHECKGLLIB definition line:
OLD:
RENDERCHECKGLLIB := -lrendercheckgl_$(LIB_ARCH)$(LIBSUFFIX)
NEW:
RENDERCHECKGLLIB := -L../../../C/lib -lrendercheckgl_$(LIB_ARCH)$(LIBSUFFIX)
2) In all files that use UtilNPP (boxFilterNPP, imageSegmentationNPP, freeImageInteropNPP, histEqualizationNPP), the makefiles have the wrong order of library linking ($LIB is before the source/out files), so go to the /CUDALibraries/src/*NPP/Makefile and change the order like (note this is an example of the freeImageInteropNPP file modification, all others are done similarly):
OLD:
$(CXX) $(INC) $(LIB) -o freeImageInteropNPP freeImageInteropNPP.cpp -lUtilNPP_$(LIB_ARCH) -lfreeimage$(FREEIMAGELIBARCH)
NEW:
$(CXX) $(INC) -o freeImageInteropNPP freeImageInteropNPP.cpp $(LIB) -lUtilNPP_$(LIB_ARCH) -lfreeimage$(FREEIMAGELIBARCH)
3) For randomFog, you also need to add
USERENDERCHECKGL := 1
to the Makefile.
