osx - 在anaconda中编译图形工具时未检测到C ++ 14编译器，多个版本的gcc [英] osx - C++14 compiler not detected, multiple versions of gcc when compiling graph-tool in anaconda
问题描述
我的最终目标是让Python包 graph_tool 在我的系统上运行，如果可能的话也运行在ipynb上。我已经 brew install graph-tool ，如此处所示，但仍然不足。 因此，我遵循 conda instructions here ，我做出了不错的进展，直到遇到配置问题。
$ conda创建-n py36env python = 3.6.3 anaconda
（py36env）$ conda install -c conda-forge cgal
...和其他所需的库

我不太熟悉编译器的东西，但我检查我的系统，如下所示：

在conda env之外：

是：EDITS INCLUDED
1） conda gcc 4.8.5 和 Homebrew gcc 7.2 在我的系统上？我很困惑，因为它们都是最新的软件包。
编辑：无处在线，我明白指出这一点，但我的理解（aka受教育的猜测bc它是凌晨3点，我需要睡眠） conda gcc 4.8.5 只是相当于 brew gcc 4.8.5 ，并且Anaconda仅仅是在开发一个支持C ++ 14的'官方'gcc。与此同时，我 conda install -c salford_systems gcc-5 和 ./configure 似乎发现自己是C ++ 14编译器。 YAY（但是这也导致我出现了一个新的问题TBA）
注意：我也曾尝试运行 ./configure 文件，其中 conda gcc 4.8.5 和 brew gcc 7.2.0 （切换默认gcc编译器在此处引导），但仍然存在<$ $的相同错误c $ c> ./configure 找不到C ++ 14编译（所以忽略）
2）我也是有Xcode 8.3.3，也带有铿锵声，这是什么海湾合作委员会symlinked ... ... ??不知道关于设置/关系
3）如何调整我的系统（例如路径），以便配置过程检测到C ++ 14编译器？编辑：解决方案1）

My ultimate goal is to get python package graph_tool working on my system and also on ipynb if possible. I have already brew install graph-tool, as indicated here, but that's still insufficient.
So I follow conda instructions here, and I make decent progress, until I encounter a compiler issue with the configuration.
$ conda create -n py36env python=3.6.3 anaconda
(py36env) $ conda install -c conda-forge cgal
... and so forth with the other required libraries
(py36env) Tams-MacBook-Pro:graph-tool-2.25 tamtam$ ./configure --prefix=/Users/tamtam/anaconda3/envs/py36env/ --with-python-module-path=/Users/tamtam/anaconda3/envs/py36env/lib/python3.6/site-packages

I'm not very familiar with compiler things, but I check my system as follows:
(py36env) Tams-MacBook-Pro:graph-tool-2.25 tamtam$ conda list | grep gcc
gcc 4.8.5 8
And outside of the conda env:
$ gcc -v
Using built-in specs.
COLLECT_GCC=gcc
COLLECT_LTO_WRAPPER=/Users/tamtam/anaconda3/envs/py36env/bin/../libexec/gcc/x86_64-apple-darwin11.4.2/4.8.5/lto-wrapper

Thread model: posix
gcc version 4.8.5 (GCC)
And with Homebrew
$ brew list --versions | grep gcc
gcc 7.1.0 7.2.0
$ /usr/local/bin/gcc-7 --version
gcc-7 (Homebrew GCC 7.2.0) 7.2.0
$ echo $PATH
/Users/tamtam/anaconda3/bin:/Users/tamtam/anaconda/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/Library/TeX/texbin
So my questions are: EDITS INCLUDED
1) What's the difference between the conda gcc 4.8.5 and Homebrew gcc 7.2 on my system? I'm confused because they're each up-to-date packages.
EDIT: Nowhere online that I perused explicitly states this, but I am understanding (aka educated guess bc it's 3am and I need sleep) conda gcc 4.8.5 to just be equivalent to brew gcc 4.8.5, and that Anaconda is just way behind on developing an 'official' gcc supporting C++14. In the meantime I conda install -c salford_systems gcc-5 and ./configure seems to find itself a C++14 compiler. YAY (but this also led me to a new problem T.B.A.)
NOTE: I had also tried running the ./configure file with both conda gcc 4.8.5 and brew gcc 7.2.0 (switching of default gcc compiler guided here), but still same error of ./configure not finding C++14 compile (so ignore this)
2) I also have Xcode 8.3.3 that also comes with clang, which is what gcc is symlinked to... ?? No idea about the setup/relation
3) How can I adjust my system (for example, paths) so that the configuration process will detect a C++14 compiler? EDIT: resolved per 1)
(This solution is also included within the edits at the bottom of my question.)
