软件安装文档很简单：https://genome.sph.umich.edu/wiki/Vt#Installation

 #this will create a directory named vt in the directory you cloned the repository
 1. git clone https://github.com/atks/vt.git  

 #change directory to vt
 2. cd vt 

 #run make, note that compilers need to support the c++0x standard 
 3. make 

 #you can test the build
 4. make test

make[1]: *** [cram/cram_io.o] Error 1
make[1]: Leaving directory `/share/work/biosoft/vt/vt-0.57721/lib/htslib'
make: *** [lib/htslib/libhts.a] Error 1

这是因为make htslib时候找不到xz软件的include导致，找到htslib的Makefile： vi lib/htslib/Makefile 添加如下内容：

-I/share/work/biosoft/xz/xz-v5.2.3/include/

保存之后继续make。

报错2：

svm_train.cpp: In member function ‘void<unnamed>::Igor::inverse_normalize(std::vector<float, std::allocator svm_train.cpp:165: error: no matching function for call to ‘sort(__gnu_cxx::__normal_iterator<float**, std:erator<float**, std::vector<float*, std::allocator<float*> > >, <unnamed>::Igor::inverse_normalize(std::vecator<float> >&)::<anonymous struct>&)’

这是因为你的gcc版本太低，最低要求4.8.1，更换较高版本：

export PATH=/share/work/biosoft/gcc/gcc-v4.8.0/bin/:$PATH

添加library路径：

export LIBRARY_PATH=/share/work/biosoft/xz/xz-v5.2.3/lib/:$LIBRARY_PATH

再make顺利编译完成
