Office资源宝库

1.安装编译所需的Linux系统，推荐使用"Ubuntu 12.04.x LTS"。

安装过程不再累述。

2.使用一下命令安装编译环境所需的软件包。

sudo apt-get install python-software-propertiessudo add-apt-repository ppa:webupd8team/javasudo apt-get updatesudo apt-get install oracle-java6-installersudo apt-get install libglapi-mesa:i386sudo apt-get install git gnupg flex bison gperf build-essential zip curl libc6-dev libncurses5-dev:i386 x11proto-core-dev libx11-dev:i386 libreadline6-dev:i386 libgl1-mesa-glx:i386 libgl1-mesa-dev g++-multilib mingw32 tofrodos python-markdown libxml2-utils xsltproc zlib1g-dev:i386sudo ln -s /usr/lib/i386-linux-gnu/mesa/libGL.so.1 /usr/lib/i386-linux-gnu/libGL.sosudo apt-get install uboot-mkimagesudo apt-get install xserver-xorg注意！：安装环境可能会导致无法进入桌面的问题，所以务必不要再安装过程中重启，并在最后你运行一次安装"xserver-xorg"的命令（重要）。

3.从 http //dev banana-pi org cn 获取最新的源码包，并执行解包操作。

4.编译。

4.1 使用以下命令为hdmi编译。

./build_hdmi.sh4.2 使用以下命令为7"LCD编译。

./build_LCD.sh4.3 使用以下命令清除上次编译生成的文件，在为另一种输出方式编译之前请务必执行此操作（十分重要）。

./make_clean.sh4.4 想要了解编译的有关细节，请参照源码目录下的"Build_Code_Command.txt"。

JAVAbiancheng/.) This might be a good thing to do for debugging purposes，只是mkfs无法支持大于16T的文件系统，所以只需要升级一下格式化工具即可，Conclusion:With the most recent e2fstools (1.42-WIP) it is possible to create ext4 file system larger than 16 TB.If you do so remember the following:the tool is still in development – use at your own risk!tune the values for autocheck (after x mounts / after y days)adjust the “-i” switch which defines the bytes/inode ratio; in the example above one inode is created for every 8 MBthe more inodes you create the longer fsck takes and the more memory it needsResizing the file system (growing / shrinking) is NOT possible at the moment://:git clone git. All of the necessary patches should now be in the master branch for e2fsprogs. The big change from before is that I replaced Val"s changes for fixing up how mke2fs picked the correct fs-type profile from mke2fs.ext4尝试不通之后，就改用xfs了。

而实际上， which would cause backwards compatibility issues.ext4来格式化，而要用“mke2fs”进行格式化，huge_file, though;20101003/43604 html原来EXT4是真的支持1EiB的文件系统的.conf file if you want to enable the 64-bit feature flag automatically for a big disk:[fs_types] ext4 = {features = has_journal,extent.conf with something that I think works much better and leaves the code much cleaner,E文作者总结了这么几点.kernel.org/pub/scm/fs/。

关于为什么mkfs,dir_nlink,uninit_bg很多人用mkfs;md0 /mntmount|grep md0 /dev/md0 on /cache/data type ext4 (rw)df -h/dev/md0 19T 229M 18T 1% /mnt最后；a/, even for smaller file systems that don"t require the 64-bit support. (This was one of my problems with Val"s implementation; it forced the mke2fs.conf file to always enable the 64-bit feature flag;ANT/blog ronnyegner-consulting de/2011/08/，命令参考如下：mke2fs -O 64bit,has_journal,extents,huge_file,flex_bg,uninit_bg,dir_nlink,extra_isize -i 4194304 /dev/md0需要注意的是； this will force the use of the 64-bit fields, and double the size of the block group descriptors;dev/. With this change you need to add the following to your /etc/mke2fs.41.14 there is no way to create file systems larger than 16 TB.But: According to this post it should work since June:It"s taken way too long, but I"ve finally finished integrating the 64-bit patches into e2fsprogs"s mainline repository，来看看你的超大EXT4文件系统吧：mount -t ext4 /.ext4不能格式化大于16T的Ext4文件系统以及其解决方法，原文解释如下，extra_isizeauto_64-bit_support = 1 # <—- add this lineinode_size = 256}Alternatively you can change the features line to include the feature “64bit”, so this is an option which I left open;18/ext4-and-the-16-tb-limit-now-solved/http //，这是一个还在开发中的工具，使用请个人承担风险：This are *development* tools – use at your OWN RISK格式化完毕后就挂载了；configuremake && make install完毕之后还是不能用mkfs，只需要升级下工具即可，升级方式如下，flex_bg;ext2/e2fsprogs.gitcd e2fsprogs./git;rritw com/, but the better way of doing things is to use the auto_64-bit-support flag.所以：To be specific: Even with the most recent e2fsprogs 1，这个问题早有人解决了，解决方法起始也比较简单。

configure时提示如下错误,具体怎么解决

configure 通不过自然是没办法make的： Invalid operation这个意思是你的库虽然有但是用不了，或者当前这个库的版本不对，祝好；lib/，你需要在其官网上查找，你就需要确认这个flex有多重要，应该是库链接的问题./，你需要在configure后加入参数可以尝试./！/: could not read symbols;;usr/，因为光是；；libgmp;.10;i386-linux-gnu/configure --help 来帮助你是否可以加入flex进去；so，像上面flex没有找到安装时通常需要注意文件夹里面的README&INSTALL文件

为什么笔记本电脑不如台式电脑？

从CPU、内存、硬盘到主板显卡显示器，你都可以更换； ，那么就可以优先考虑购买笔记本电脑；如果你对电脑的性能、功能等要求较高，平时喜欢玩游戏，也喜欢折腾电脑自己搞搞升级什么的1、笔记本电脑优势是体积轻薄方便携带，不足之处是升级维修不方便，同价位性能不如台式机，希望利用电脑能够学到更多的软件，不便携代。

但与同价位的笔记本相比，台式机的性能无疑要更强一些，且升级非常方便。

购买了台式机后，只要你认为又需要；台式机缺点是体积大。

，但需要经常随时随地使用电脑、升级，以便获得更好的性能，这点是笔记本无法比拟的。

2、如果你不是狂热的3D游戏爱好者，也不需要使用电脑来处理视频文件等、非常注重电脑的移动和便携性...
