Question

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

使用scons的tmv

tmv0.72）{58}＆GT; scons安装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. Using python = /home/rgm/anaconda/bin/python Using default PYPREFIX = /home/rgm/anaconda/lib/python2.7/site-packages Using compiler: /home/rgm/anaconda/bin/g++ compiler version: 4.8.5 Determined that a good number of jobs = 4 Checking for C++ header file fftw3.h... yes Checking for correct FFTW linkage... yes Checking for boost header files... yes Boost version is 1.57.0 Checking for C++ header file TMV.h... yes TMV version is 0.72 Using TMV_LINK file: /Users/rgm/local/share/tmv/tmv-link -L/home/rgm/local/lib -ltmv -lblas -lpthread -fopenmp Mac version is 10.10.5 XCode version is 7.2 Checking for correct TMV linkage...

在config.log中查找有以下行：

Undefined symbols for architecture x86_64: "_fftw_destroy_plan", referenced from: _main in conftest_2.o

Answer 1

这里最近的问题是它无法在运行时找到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"

我之前在Mac上遇到过与Anaconda类似的麻烦。他们似乎试图强迫Mac使用Unix风格的运行时库分辨率，而不是遵循Mac正常的方式，这是根本不同的。特别是，这个@rpath的东西在Linux / Unix系统上运行得非常好，但在Mac上并没有那么多。我想使用他们自己的conda安装的库，他们有办法使它完全正常工作，但它不能很好地与以普通Mac方式安装的外部库相互啮合。

无论如何，由于它只是TMV中的OpenMP内容，并且GalSim中的矩阵操作从来都不是时间关键，因此最简单的选择可能是使用scons install WITH_OPENMP=false安装没有OpenMP支持的TMV。

然后再次尝试安装GalSim。

使用conda环境在OSX上安装Galsim：fftw / tmv文件无法正确链接
