Trouble installing about pyhector HOT 12 CLOSED

On Mac OSX 10.14.6 I had trouble installing in development mode:

    warning: include path for stdlibc++ headers not found; pass '-stdlib=libc++' on the command line to use the libc++ standard library instead [-Wstdlibcxx-not-found]

             ^~~~~~~~~
    1 warning and 1 error generated.
    error: command 'gcc' failed with exit status 1

I successfully installed with this command:

$ cd pyhector
$ CC="gcc -stdlib=libc++" pip install -e .

from pyhector.

Hi,

how did you install boost? Through Homebrew?

Maybe you can try installing Python3 through Homebrew as well? That's how I tested on OS X, I haven't tried with the built-in Python.

So

brew install python3

mkdir test

cd test

python3 -m venv venv

./venv/bin/pip install pip --upgrade

./venv/bin/pip install pyhector 

from pyhector.

Thanks for the quick response!

I installed boost through Homebrew.

Running your suggestion gave me the same error.

from pyhector.

In your screenshot it lists the OS X version as 10.6, is that right?

Can you give the version of clang?

clang --version

Can you maybe also try installing boost in explicit C++11 mode?

brew install boost --c++11

It might also be necessary to use a different compiler option in setup.py e.g. -stdlib=libc++, but I'm not expert here ...

Hi,
Looks like this is an issue with the C++ Standard flag in Clang.
I hope it's working now...

from pyhector.

Thanks @swillner!
@russellhz to install and test the head version from master you would need to follow the Development instructions here:
https://github.com/openclimatedata/pyhector#development

from pyhector.

@russellhz Did you get a chance to try it again? We just published v0.6.0 with explicitly setting the C++ standard to 11, so you should be able to try with just

pip install pyhector

from pyhector.

@rgieseke I'm getting the same error messages.

This is my clang version.

from pyhector.

Thanks for the feedback, will try again on my Mac later ...

from pyhector.

What confuses me is that your first screen shot is showing macosx-10.6

When I do a fresh clone on my 10.11 machine:

git clone https://github.com/openclimatedata/pyhector.git --recursive

and then

python setup.py build_ext --inplace

I get

running build_ext

There are quite a few issues with compiling with Clang and older versions of OS X (see e.g. http://stackoverflow.com/questions/19774778/when-is-it-necessary-to-use-use-the-flag-stdlib-libstdc/19774902#19774902) and libc++ vs. libstdc++

Maybe your Python is older?

When you just start python, what does it display?

Mine shows

Python 2.7.13 (default, Apr  4 2017, 08:46:44) 
[GCC 4.2.1 Compatible Apple LLVM 8.0.0 (clang-800.0.42.1)] on darwin

from pyhector.

@rgieseke you figured it out.

I have multiple pythons installed on my machine. Home-brew installed one which displays:

while my default python is:

I was able to install pyhector into the Homebrew python. Thank you so much for your help!

That's great to hear! I'll add a note that it might be advisable to use a Homebrew installed Python with a Homebrew installed boost library ...
