-#### 介绍
-IBM's TCG Software Stack (TSS) for TPM 2.0 and related utilities
-
-#### 软件架构
-软件架构说明
+Linux Specific build notes
+--------------------------
+Written by Ken Goldman
+IBM Thomas J. Watson Research Center
 
 
-#### 安装教程
+Prior to the autotools support, most users began by untarring the
+tarball or cloning the git repo, and then executing 'make' or 'make -f
+<makefile>' in the utils and utils12 directories.  For autotools and the
+existing makefiles to co-exist, the existing "makefile" was renamed to
+"makefiletpmc".
 
-1.  xxxx
-2.  xxxx
-3.  xxxx
+$ cd utils
+$ make -f makefiletpmc
+$ cd utils12
+$ make -f makefiletpmc
 
-#### 使用说明
+This builds a TSS
+- with TPM 2.0 and TPM 1.2 support,
+- connecting to a TPM 2.0 SW TPM,
+- with TSS state files in cwd,
+- with tracing support,
+- and with elliptic curve support.

-#### 码云特技
+Autotools
+---------
 
-1.  使用 Readme\_XXX.md 来支持不同的语言，例如 Readme\_en.md, Readme\_zh.md
-2.  码云官方博客 [blog.gitee.com](https://blog.gitee.com)
-3.  你可以 [https://gitee.com/explore](https://gitee.com/explore) 这个地址来了解码云上的优秀开源项目
-4.  [GVP](https://gitee.com/gvp) 全称是码云最有价值开源项目，是码云综合评定出的优秀开源项目
-5.  码云官方提供的使用手册 [https://gitee.com/help](https://gitee.com/help)
-6.  码云封面人物是一档用来展示码云会员风采的栏目 [https://gitee.com/gitee-stars/](https://gitee.com/gitee-stars/)
+On Linux (and probably other Unix systems), open source projects expect
+the normal shell command 'autoreconf -i && ./configure && make && make install'
+should configure and build the package.
+
+Example 1: To configure the TSS library to use the software TPM, build and
+install the package in ${HOME}/local/bin and ${HOME}/local/lib directories
+execute the following shell commands:
+
+$ autoreconf -i
+$ ./configure --prefix=${HOME}/local --disable-hwtpm
+$ make clean
+$ make
+$ make install
+
+An initial set of the most common TSS "./configure" options are defined
+to enable/disable different features.
+
+--disable-tpm-2.0 - include only TPM 1.2 support
+--disable-tpm-1.2 - include only TPM 2.0 support
+--disable-hwtpm   - don't use the hardware TPM, use a software one instead
+--disable-rmtpm   - when using a hardware TPM, don't use the resource manager
+--enable-noprint  - build a TSS library without tracing or prints
+--enable-nofile   - build a TSS library that does not use files to preserve state
+--enable-nocrypto - build a TSS library that does not require a crypto library
+		    (dependency on "--enable-nofile")
+--enable-noecc    - build a TSS library that does not require OpenSSL elliptic curve support
+--enable-debug    - build a TSS library used for debugging.
+
+Example 2: To configure the TSS library to use the hardware TPM, build and
+install the package in the default /usr/local directories requires root
+privileges.  Executing the following shell commands will make and install the
+package in the default directories.
+
+$ autoreconf -i
+$ ./configure
+$ make clean
+$ make
+$ sudo make install
+
+Other TSS features can be modified by specifying them directly as CFLAGS
+"./configure" options.
+
+CFLAGS='<options>'
+options:
+-O0					- change compiler optimization (default: 02)
+-DTPM_DEVICE_DEFAULT="\"/dev/tpmrm0\""	- change hardware TPM (default: /dev/tpm0)
+-DTPM_DATA_DIR_DEFAULT="\"<pathname>\""	- specify directory for TSS state files
+-DTPM_TRACE_LEVEL_DEFAULT="\"<level>""	- change level of tracing (default: 0)
+	0 - no tracing
+	1 - trace errors
+	2 - trace errors and execution flow
+
+Example 3: To install the package in ${HOME}/local/bin and ${HOME}/local/lib
+directories, compile for the gdb debugger, and connect by default to a socket
+simulator TPM at command port 3333, execute the following shell commands:
+
+$ autoreconf -i
+$ ./configure --prefix=${HOME}/local --enable-debug --disable-hwtpm \
+CFLAGS='-DTPM_INTERFACE_TYPE_DEFAULT="\"socsim\"" -DTPM_COMMAND_PORT_DEFAULT="\"3333\""'
+$ make clean
+$ make
+$ make install
+
+The TPM utility binaries are stored in utils/.lib and utils12/.lib directories
+of the source directory.[1]  To debug using these binaries in the source tree,
+use either the binary stored in .lib or the libtool command.
+
+$ libtool --mode=execute gdb <.lib/utility>
+
+[1] For an explanation, refer to the GNU documentation
+https://www.gnu.org/software/libtool/manual/libtool.html#Debugging-executables.
+
+
+Advanced options
+----------------
+
+For all options and details, see the documentation in ibmtss.doc or
+ibmtss.html.
+
+Some of the more common options are below.
+
+1-3 can also be specified in an environment variable or at run time.
+
+4-8, which are used to reduce the size of the library, must be
+specified at compile time.
+
+1) To default to a hardware TPM (rather than the SW TPM)
+
+Add to CCLFLAGS:
+
+	-DTPM_INTERFACE_TYPE_DEFAULT="\"dev\""
+
+2) To default to /dev/tpmrm0 (rather than /dev/tpm0)
+
+Add to CCLFLAGS:
+
+	-DTPM_DEVICE_DEFAULT="\"/dev/tpm0\""
+
+3) To default to a different directory for TSS state files (rather
+than cwd)
+
+Add to CCLFLAGS:
+
+	-DTPM_DATA_DIR_DEFAULT="\"directory\""
+
+4) To remove TPM 1.2 support
+
+Delete from CCLFLAGS and CCAFLAGS
+
+	-DTPM_TPM12
+
+5) To remove the requirement for a filesystem (see documentation for
+limitations)
+
+Add to CCFLAGS
+
+	-DTPM_TSS_NOFILE
+
+6) To remove the requirement for crypto (see documentation for
+limitations)
+
+Add to CCFLAGS
+
+	-DTPM_TSS_NOCRYPTO
+
+7) To remove print tracing support
+
+Add to CCFLAGS
+
+	-DTPM_TSS_NO_PRINT
+
+8) To remove elliptic curve dependencies
+
+Add to CCFLAGS
+
+	-DTPM_TSS_NOECC
