我已经用 conda 安装了 fftw 和 boost；

conda install -c https://conda.anaconda.org/anaconda boost

conda install -c https://conda.anaconda.org/nlesc fftw

tmv 与 scons

tmv0.72){58}> scons install PREFIX=/home/rgm/local

具有前面指定的各种变量的 scons，如下所示：

scons 
scons: Reading SConscript files ...
SCons is version 2.3.5 using python version 2.7.10
Python is from /System/Library/Frameworks/Python.framework/Versions/2.7/include/python2.7
Using the following (non-default) scons options:
PREFIX = /home/rgm/local/
TMV_DIR = /Users/rgm/local
FFTW_DIR = /Users/rgm/anaconda/
BOOST_DIR = /Users/rgm/anaconda/
These can be edited directly in the file gs_scons.conf.
Type scons -h for a full list of available options.

查看 config.log 有如下几行：

  "_fftw_destroy_plan", referenced from:
  _main in conftest_2.o

这里最接近的问题是它在运行时找不到 OpenMP 库 (libgomp.1.dylib)。以下是 config.log 中的相关行：

g++ -o .sconf_temp/conftest_16 -fopenmp .sconf_temp/conftest_16.o -Llib -L/Users/rgm/anaconda/lib -L/Users/rgm/local/lib -L/home/rgm/local/lib -ltmv_symband -lfftw3 -lpthread -ltmv -lblas -lpthread
.sconf_temp/conftest_16 > .sconf_temp/conftest_16.out
dyld: Library not loaded: @rpath/./libgomp.1.dylib
  Referenced from: /data/vault/rgm/soft/MACOS/GalSim/.sconf_temp/conftest_16
  Reason: image not found
sh: line 1: 20592 Trace/BPT trap: 5       .sconf_temp/conftest_16 > ".sconf_temp/conftest_16.out"

我以前在 Mac 上遇到过类似的问题。他们似乎试图强制 Mac 使用 Unix 风格的运行时库解析，而不是遵循 Mac 的正常方式，这是根本不同的。特别是，@rpath 这个东西在 Linux/Unix 系统上运行得非常好，但在 Mac 上就不行了。我猜他们自己安装了 conda 的库，他们有办法让一切正常工作，但它与以普通 Mac 方式安装的外部库不太吻合。

无论如何，因为它只是 TMV 中的 OpenMP 东西，而且 GalSim 中的矩阵运算从来都不是时间关键的，所以您最简单的选择可能是使用scons install WITH_OPENMP=false.

然后再次尝试安装 GalSim。
