ubuntu安装hhsuite/hhblits全过程！
1.由于是刚刚装好的ubuntu，首先需要安装一些必备工具例如git。
sudo apt install git
报错： 依赖: liberror-perl 但无法安装它
解决：
sudo apt-get update
sudo apt-get upgrade
sudo apt install git
git安装成功！
2.根据官网给出的方法安装hhsuite
# 下载包
git clone https://github.com/soedinglab/hh-suite.git
cd hh-suite
# 编译最新版本，初始化子模块
git submodule init
git submodule update
# 安装
mkdir build
cd build
cmake -DCMAKE_BUILD_TYPE=RelWithDebInfo -G "Unix Makefiles" -DCMAKE_INSTALL_PREFIX=/usr/opt/hhsuite ..
make
sudo make install
sudo apt-get upgrade
sudo apt-get install hhsuite
#测试安装是否成功
hhblits -h
下面是具体安装过程
到cmake这一步时报错：
Command ‘cmake’ not found, but can be installed with:
sudo apt install cmake
解决：安装cmake
sudo apt install cmake
接着输入cmake命令行，又报错：
CMake Error at CMakeLists.txt:2 (project):
No CMAKE_CXX_COMPILER could be found.
Tell CMake where to find the compiler by setting either the environment
variable “CXX” or the CMake cache entry CMAKE_CXX_COMPILER to the full path
to the compiler, or to the compiler name if it is in the PATH.
解决：
sudo apt-get update
sudo apt-get install -y build-essential
make install 又报错：
CMake Error at lib/ffindex/src/cmake_install.cmake:47 (file):
file INSTALL cannot set permissions on
“/usr/opt/hhsuite/bin/ffindex_reduce”
Call Stack (most recent call first):
lib/ffindex/cmake_install.cmake:42 (include)
cmake_install.cmake:42 (include)
解决：
sudo make install
成功！！
3.修改地址
export HHLIB=/home/yl/hh-suite #改成你自己的地址
export PATH=$PATH:$HHLIB/bin:$HHLIB/scripts
或修改.bashrc文件：
命令行输入
gedit ~/.bashrc
在文档最后添加：
export HHLIB=/usr/local/
PATH=$PATH:$HHLIB/bin>$HHLIB/scripts
alias hhblits=’hhblits -d <path_to/uniprot20>’#默认数据库地址，需要修改
4.尝试了官网的另一种方法，先下载包再解压安装，这样的问题是缺少cmake文件，可以在github中下载其他文件放到hhsuit文件夹中。
