ubuntu 编译openpts

在ubuntu12.04和14.04上编译openpts，遇到了很多无语的问题。现将一些过程记录。

1、获取源码

     我的源码是openpts-0.2.6版本，

    http://openpts.osdn.jp/

2、解压源码包

  tar xvf openpts-0.2.6.tar.gz

3、根据README来编译

    1)、安装必要的包。

    sudo  apt-get install  automake autoconf libtool cvs fakeroot debhelper  gettext   trousers libtspi-dev tpm-tools 

      libxml2 libxml2-dev   libuuid1 uuid-dev  check 

  2)、根据错误安装别的包

    apt-get install autopoint

  3)、根据错误修改源码

4、这是折腾很久的问题，也查了很多资料，求教了很多人，没有任何办法。分析了很多遍makefile

  错误信息如下：

有一篇文章http://trousers.sourceforge.net/

  所以了我推出了两个可能。一是GCC的原因，而是由于库链接顺序的问题。

我在一台机器上安装gcc4.4版本。另一台机器安装gcc4.6

1、在GCC4.4的机器上成功编译

2、在GCC4.6的机器不能成功编译。这是由于动态链接库的问题。gcc的链接顺序语法。

  通过分析undefined log信息，分别查找这些函数在哪些库中，基本的trouser给libopenpts库提供基本的函数，而libopenpts库需要用到其他的库函数，所以必须这些库函数必须要在libopenpts的后面。

做如下修改： 

  将AM_LDFLAGS 定义语句稍微修改一下即可。

改动前

AM_LDFLAGS = $(LIBXML2_LIBS) $(LIBCRYPTO_LIBS) $(TSS_LIBS)   -lopenpts  \    
   $(am__append_2) $(am__append_16) $(am__append_18)

改动后：  

AM_LDFLAGS = -lopenpts $(LIBXML2_LIBS) $(LIBCRYPTO_LIBS) $(TSS_LIBS)  \    
     $(am__append_2) $(am__append_16) $(am__append_18)

编译遇到警告的错误时，按照函数手册修改即可。
