Hi Raphael, Can you please let me know which exact version of g++ are you using? In addition, please try using the Try also with I'll make a point on adding a bit of documentation about this additional environment variable. |

Hi, Thanks, that has got me a bit further, I was trying to edit the environment variable using os.environ(). My g++ version is I think the most recent version of clang: mps017431:examples rs548$ g++ -v I have just moved over to a mac so am a bit inexperienced I'm afraid. It now throws these two warnings but then seems to have installed correctly: Using -std=c++11 to enable C++11 support but then when I run python usage.py in examples I get the following: Traceback (most recent call last): Many thanks for your help. I aim to extend your code to fitting two galaxy profiles in blended images so will eventually be wanting to add a c++ class. I have included the full output from setup.py below incase it is helpful. Best regards, Raphael. mps017431:pyprofit rs548$ CC=g++ PYPROFIT_CXX11="-std=c++11" python setup.py install Installed /Users/rs548/anaconda/lib/python3.5/site-packages/pyprofit-1.0-py3.5-macosx-10.6-x86_64.egg |

Hi Raphael, Thanks for the information. The compilation warnings are fine, and the module indeed compiled successfully, so the original problem I would say it is fixed, and I'm closing this ticket accordingly. You were using g++ which is usually the name for the GNU C++ compiler, so I thought you were using that one. If you keep using clang, use cland/clang++ for compiling C/C++ programs. Maybe that would have picked up the correct standard automatically already. Regarding the new problem, I'll create a second ticket to record it. I've seen this issue before elsewhere and I think I have an idea of what might be causing it. On a final note, if you are actually planning to work mostly on C++ you might want to use libprofit (ICRAR/libprofit repository) directly instead of pyprofit, which simply wraps libprofit. |

Great, thanks. I wondered if there might be python 3 issue. We may decide to use c++ but plan on possibly using some old python code and python is our preferred code here for development. Thanks again for your help. Best, Raphael. |
Hello,
Thank you very much for making this software available. I am trying to use the software with a view to applying it to galaxy deblending problems we are working on at the University of Sussex Astronomy Centre.
I am struggling to install the python package using 'python setup.py install' which throws the following error:
/var/folders/zx/nzb1wy_d0yj1g8wznhz1ns68000930/T/tmplanbqx8y.cpp:4:21: error: cannot deduce type of initializer list because

No C/C++ compiler with C++11 support found. Use the CC environment variable to specify a different compiler if you have one
Using None to enable C++11 support
It is clearly a c++ compiler problem. I seem to be able to compile the test code in the setup.py file using g++ on a mac with 'g++ -std=c++ main.cpp' but when that is run in setup.py it throws the error after setting the CC envirnoment variable to g++.
Do you have any suggestions for fixing this problem. I get the same errors when I try to use pip.
Sorry if I'm doing something stupid.
