DiskSim的安装过程（一）
最近要和师兄做一个关于瓦记录的项目，要用到DiskSim来模拟硬盘的读写，现在就记录下我的安装过程
首先用师兄传给我的disksim_1.0源码试了一下，安装过程如下：
- 解压缩
- 在src文件夹中（也就是Makefile的目录）执行make，虽然在编译试有些警告信息但是编译能够通过
[WangZhi@Panda-CentOS DiskDim]$ tar -zxf disksim1.0.tar.gz [WangZhi@Panda-CentOS DiskDim]$ cd disksim1.0 [WangZhi@Panda-CentOS disksim1.0]$ ls CVS doc README src valid [WangZhi@Panda-CentOS disksim1.0]$ cd src [WangZhi@Panda-CentOS src]$ ls COPYRIGHT disksim_cache.c disksim_disk.c disksim_global.h disksim_ioface.h disksim_logorg.c disksim_pfsim.h hplcomb.c CVS disksim_cache.h disksim_diskcache.c disksim_hptrace.h disksim_ioqueue.c disksim_logorg.h disksim_redun.c Makefile disksim_assertlib.h disksim_controller.c disksim_diskctlr.c disksim_interface.c disksim_ioqueue.h disksim_orgface.h disksim_stat.c rms.c disksim_bus.c disksim_controller.h disksim_disk.h disksim_intr.c disksim_iosim.c disksim_pfdisp.c disksim_stat.h syssim_driver.c disksim_bus.h disksim_ctlrdumb.c disksim_diskmap.c disksim_iodriver.c disksim_iosim.h disksim_pfface.h disksim_synthio.c syssim_driver.h disksim.c disksim_ctlrsmart.c disksim_diskmech.c disksim_iodriver.h disksim_iotrace.c disksim_pfsim.c disksim_synthio.h [WangZhi@Panda-CentOS src]$ make
- 按照文档上的测试时出现了如下的错误

错误为：
free(): invalid next size (fast)是在内存回收时出了问题
我决定去下载最新的版本（V4）试一下，我下载的是不带DIXtrac的版本， http://http://www.pdl.cmu.edu/DiskSim/
这次安装的过程和第一次差不多也是解压编译，只不过V4版本的Makefile文件就在根文件下
[WangZhi@Panda-CentOS DiskDim]$ tar -zxf disksim-4.0.tar.gz [WangZhi@Panda-CentOS DiskDim]$ cd disksim-4.0 [WangZhi@Panda-CentOS disksim-4.0]$ ls COPYING diskmodel doc libddbg libparam Makefile memsmodel README src utils valid [WangZhi@Panda-CentOS disksim-4.0]$ make
在编译的时候出现了如下的错误
disksim_iosim.c: In function ‘iosim_load_map’: disksim_iosim.c:364: warning: cast to pointer from integer of different size disksim_iosim.c: In function ‘io_initialize’: disksim_iosim.c:712: error: duplicate case value disksim_iosim.c:712: error: previously used here make[1]: *** [disksim_iosim.o] Error 1 make[1]: Leaving directory `/home/WangZhi/Desktop/DiskDim/disksim-4.0/src' make: *** [all] Error 2
disksim_iosim.c的712行源码为：
703 void io_initialize (int standalone)
704 {
705 if (disksim->iosim_info == NULL) {
706 iosim_initialize_iosim_info ();
707 }
708
709 bus_set_depths();
710 // fprintf (outputfile, "Back from bus_set_depths\n");
711
712 StaticAssert (sizeof(ioreq_event) <= DISKSIM_EVENT_SIZE);
713 device_initialize();
714 bus_initialize();

716 iodriver_initialize(standalone);
717 }
参考这篇文章 http://http://blog.chinaunix.net/uid-28412198-id-3765266.html 将这一行注释再运行编译程序，果然没问题了，再次运行验证程序

出现了 Segmentation fault 的错误 再去搜索这个错误，发现在 http://http://blog.sina.com.cn/s/blog_6464a7210100ghsy.html有如下的描述
SSD extension for DiskSim is an extensional module of DiskSim which implments SSD I/O Models. It is implemented by Microsoft Research.
Compiling DiskSim and SSD extension is very simple, but when I tried, there was some problem.
This article addresses those problems.
DiskSim does not compile in 64bit environment. Never try it. Even if you succeded compilation, it will not run -- just produces segmentation fault.
DiskSim requires bison and flex, which are parser generators for parameter file parsing codes.
原来disksim不支持64位的系统。。。。。。。。。
看来待会儿得装个32位的系统再试试
