安装方法：https://bedtools.readthedocs.io/en/latest/content/installation.html
$ wget https://github.com/arq5x/bedtools2/releases/download/v2.25.0/bedtools-2.25.0.tar.gz
$ tar -zxvf bedtools-2.25.0.tar.gz

源码安装，直接make，会报错如下：我的gcc版本：gcc version 4.4.7 20120313 (Red Hat 4.4.7-17) (GCC)，
CURRENT_VERSION =
Updating version file.
* Creating BamTools API
- Building in src/utils/FileRecordTools
* compiling FileRecordMgr.cpp
cc1plus: error: unrecognized command line option "-std=c++11"
make[1]: *** [../../../obj//FileRecordMgr.o] Error 1
make: *** [src/utils/FileRecordTools] Error 2
这是因为gcc版本太低，提高版本，make顺利通过：
export PATH=/share/work/biosoft/gcc/gcc-v4.8.0/bin/:$PATH
