Ubuntu22.04安装Madagascar遇scons报错：sfpseudodepth环境冲突

问题概述 #

我是Linux新手，在Ubuntu22.04系统上安装Madagascar时，执行make install后出现错误，根源是SCons报重复目标定义的错误。尝试修改安装路径后问题依旧。

错误信息 #

执行make install时的错误：

make: *** [Makefile:7: install] Error 2

SCons核心报错：

scons: *** Two environments with different actions were specified for the same target: sfpseudodepth

我的SConstruct文件内容 #

操作步骤及配置输出 #

1. 执行configure命令 #

(base) master@MasterComputer:~/Python/Madagascar/madagascar-4.0$ ./configure --prefix=/home/master/Python/Madagascar

关键配置输出：

checking for Python ... /home/master/anaconda3/bin/python
checking Python version ... 3.9.13
checking for RSFROOT ... /home/master/Python/Madagascar
checking for SCons ... /home/master/anaconda3/bin/scons

scons: *** Two environments with different actions were specified for the same target: sfpseudodepth
File "/home/master/Python/Madagascar/madagascar-4.0/build/user/xuxin/SConstruct", line 61, in <module>

2. 执行make install命令 #

(base) master@MasterComputer:~/Python/Madagascar/madagascar-4.0$ make install

输出：

RSFROOT=/home/master/Python/Madagascar PYTHONPATH=/home/master/Python/Madagascar/lib/python3.9/site-packages /home/master/anaconda3/bin/scons install
scons: Reading SConscript files ...

scons: *** Two environments with different actions were specified for the same target: sfpseudodepth
File "/home/master/Python/Madagascar/madagascar-4.0/build/user/xuxin/SConstruct", line 61, in <module>
make: *** [Makefile:7: install] Error 2

问题原因 #

从配置输出可见，系统未安装LAPACK库，此时SConstruct的逻辑出现冲突：

1. 开头progs变量已包含pseudodepth
2. 因lapack检测为no，进入elif root:分支，调用env.RSF_Place('sfpseudodepth'...)并执行安装
3. 后续遍历mains = Split(progs)时，又为pseudodepth创建编译任务并执行安装

同一目标文件sfpseudodepth被两个不同的SCons操作重复定义，触发报错。

修复方案 #

1. 修改SConstruct文件 #

移除开头progs变量中的pseudodepth，确保该程序只在一个分支中处理：

progs = '''
integral1
'''

修改后，LAPACK存在时会将pseudodepth添加到编译列表；LAPACK不存在时，只会执行RSF_Place逻辑，不会重复定义目标。

2. 安装依赖（可选，如需pseudodepth功能） #

如果需要使用pseudodepth工具，先安装LAPACK依赖：

sudo apt-get install liblapack-dev libblas-dev

之后重新执行./configure和make install即可正常编译。
