64位环境编译DiskSim 4.0
DiskSim没有64位版本，即使侥幸编译成功，运行时也会出现段错误。因此需要对源码进行一些修改，才能在64位环境使用，下文总结了在Ubuntu 64bit上编译DiskSim的全过程。
DiskSim需要bison和flex，如下：
在链接libmems_internals.a时，提示mems_hong_seek.c中的sqrt、acos等引用未定义，这个错误的原因是未链接math库。检查memsmodel/Makefile，发现：
其中LDFLAGS变量包含了-lm，应该将$(LDFLAGS)移到-lmems_internals后面。此类错误不止一处，在src/Makefile里定义的LDFLAGS
需要加-lm放到最后。同样的，在dixtrac/Makefile里，LDFAGS的定义
也需要将-lm放到最后。
这个错误的意思是switch语句里面，两个case使用了相同的值。出错的代码在src/disksim_iosim.c:712，代码很有意思：
而StaticAssert的定义是：
sizeof(ioreq_event)和DISKSIM_EVENT_SIZE的值可以在编译时获得，当不等式不成立时，c==0导致编译错误。这行代码旨在检测运行环境是否32位。有的解决方法是加上-m32选项，这个选项会将程序按照32位编译，但是我试过之后会遇到其它问题，而且既然不是32位环境，这句判断也就多余，所以我这里将其注释，并且继续按照64位程序进行编译。
到此，程序应该已经编译成功，但是如果尝试运行的话，一定会遇到很多段错误，不信可以运行valid/runvalid试一试。我在一个博客（DiskSim 4.0 - 64bit patch和DiskSim 4.0 + SSD extention : 64bit patch）里找到了解决方案，patch如下：
patch不是很完善，可手动添加。
现在运行valid/runvalid不会出现段错误了。
1.安装bison和flex
DiskSim需要bison和flex，如下：
apt-get install bison flex
2.math库的依赖问题
在链接libmems_internals.a时，提示mems_hong_seek.c中的sqrt、acos等引用未定义，这个错误的原因是未链接math库。检查memsmodel/Makefile，发现：
mems_seektest: mems_seektest.o libmems_internals.a
$(CC) -o $@ mems_seektest.o $(LDFLAGS) $(CFLAGS) -lmems_internals
其中LDFLAGS变量包含了-lm，应该将$(LDFLAGS)移到-lmems_internals后面。此类错误不止一处，在src/Makefile里定义的LDFLAGS
LDFLAGS = -lm -L. -ldisksim $(DISKMODEL_LDFLAGS) $(MEMSMODEL_LDFLAGS)
$(LIBPARAM_LDFLAGS) $(LIBDDBG_LDFLAGS)
需要加-lm放到最后。同样的，在dixtrac/Makefile里，LDFAGS的定义
LDFLAGS = -L. -lm -l$(LIBNAME) -ldxtools
$(LIBDISKSIM_LDFLAGS)
$(MEMSMODEL_LDFLAGS)
$(DISKMODEL_LDFLAGS)
$(LIBPARAM_LDFLAGS)
$(LIBDDBG_LDFLAGS)
$(ST_LDFLAGS)
也需要将-lm放到最后。
3.duplicate case value
这个错误的意思是switch语句里面，两个case使用了相同的值。出错的代码在src/disksim_iosim.c:712，代码很有意思：
StaticAssert (sizeof(ioreq_event) <= DISKSIM_EVENT_SIZE);
而StaticAssert的定义是：
#define StaticAssert(c) switch (c) case 0: case (c):
sizeof(ioreq_event)和DISKSIM_EVENT_SIZE的值可以在编译时获得，当不等式不成立时，c==0导致编译错误。这行代码旨在检测运行环境是否32位。有的解决方法是加上-m32选项，这个选项会将程序按照32位编译，但是我试过之后会遇到其它问题，而且既然不是32位环境，这句判断也就多余，所以我这里将其注释，并且继续按照64位程序进行编译。
4.段错误
到此，程序应该已经编译成功，但是如果尝试运行的话，一定会遇到很多段错误，不信可以运行valid/runvalid试一试。我在一个博客（DiskSim 4.0 - 64bit patch和DiskSim 4.0 + SSD extention : 64bit patch）里找到了解决方案，patch如下：
