简介一下安装CosmoSIS的辛酸历程，可能可以帮助跟我一样的菜鸟
安装机器在一台没有sudo权限的小服务器，系统centus_7，python用的是Anaconda2
https://bitbucket.org/joezuntz/cosmosis/wiki/Manual%20Install
按照指南安装dependencies，系统里确定有gcc,git，其他4个不确定就分别下载，研究安装方法和调试错误花了好多天……
下载gsl-latest.tar.gz
tar gsl-latest.tar.gz
cd gsl-2.1
./configure --prefix=$HOME/lib/gsl
make
make install
cfitsio3390.tar.gz
tar xvf cfitsio3390.tar.gz
cd cfitsio
./configure --prefix=$HOME/lib/cfitsio （最后对CosmoSIS进行make的时候失败了多次，回到这里多次尝试，加了CFLAGS=-fPIC CPPFLAGS=-fPIC，也不知道是不是这个的原因……）
make shared（不加shared的话只生成libcfitsio.a，没有libcfitsio.so）
make install
fftw-3.3.5.tar.gz
tar xvf fftw-3.3.5.tar.gz
cd fftw-3.3.5
./configure CFLAGS=-fPIC LDFLAGS=-fPIC CPPFLAGS=-fPIC FFLAGS=-fPIC --prefix=$HOME/lib/fftw （死马当活马医加了一堆-fPIC成功了……可以./configure --help查查）
make
make install
lapack-3.6.1.tgz
唯一一个按照网上攻略能装成功的，http://maslino.website/post/compile-installation-blas-and-lapack.html
tar zxf lapack-3.6.1.tgz
cd lapack-3.6.1
cp INSTALL/make.inc.gfortran make.inc # On Linux with lapack-3.2.1 or newer
make lapacklib
vi make.inc
修改选项，给OPTS和NOOPT这两个设置都加上-fPIC选项，结果如下：
FORTRAN = gfortran
OPTS = -O2 -frecursive -fPIC -m64
DRVOPTS = $(OPTS)
NOOPT = -O0 -frecursive -fPIC -m64
LOADER = gfortran
:x
make
python的东西anaconda里面都有，再按照cosmosis网站上介绍的安装emcee，下载cosmosis主体
3 setup script里面，Edit the new file setup-my-cosmosis也蛮麻烦的，附上我的setup-my-cosmosis
#This script is only used if you did a manual installation of CosmoSIS;
#i.e. if you did not use the "bootstrap" script and have no "ups" directory
#See the wiki https://bitbucket.org/joezuntz/cosmosis/wiki/edit/Manual%20Install
#on how to change and use this file
export COSMOSIS_SRC_DIR=$HOME/cosmosis

export GSL_LIB=$HOME/lib/gsl/lib

export CFITSIO_LIB=$HOME/lib/cfitsio/lib

export FFTW_INC_DIR=$HOME/lib/fftw/include
#The lapack linear algebra package
#On a mac this should just say "-framework Accelerate" or "-framework veclib" if that doesn't work
export LAPACK_LINK="-L ~/InstallCosmosis/lapack-3.6.1/liblapack.a -llapack -lblas"
#You may need to add :${DYLD_LIBRARY_PATH} to the end of this
export DYLD_LIBRARY_PATH=/usr/lib64/libgfortran.so.3.0.0:${COSMOSIS_SRC_DIR}/cosmosis/datablock/:${COSMOSIS_SRC_DIR}/cosmosis-standard-library/likelihood/:${COSMOSIS_SRC_DIR}/cosmosis-standard-library/likelihood/planck/plc-1.0/lib/:${COSMOSIS_SRC_DIR}/cosmosis-standard-library/likelihood/planck2015/plc-2.0/lib/

export PYTHONPATH=${COSMOSIS_SRC_DIR}:${PYTHONPATH}
export PATH=${COSMOSIS_SRC_DIR}/bin:/usr/bin/gcc:~/anaconda2/bin/python:${PATH}
其中那几个软件包都是在安装时用--prefix选择的位置，lapack不知道怎么选择位置，装在了安装包文件夹下
gcc/python的位置用which gcc/python得到
libgfortran的位置用rpm -ql libgfortran
之后在对cosmosis进行make时，libgfortran出错，使用conda update libgfortran进行修复
网上另一修复办法为
conda remove libgfortran
conda install libgcc --force
回到cosmosis网页完成安装，make成功，cosmosis demos/demo1.ini成功
