pyemd not building on MacOS X "Catalina" + Python 3.7

[arianpasquali]

pyemd fails to install on python 3.7 environment on Mac OS X Catalina (version 10.15 beta). similar to issue [#39] (https://github.com/wmayner/pyemd/issues/39)

I am using virtualenv with python 3.7.1.

Any updates? Textacy fails to install because of this.

Facing the same issue; any solutions?

[big-c-note]

Same here

[umamicode]

having the same problem here, is this a common issue?

[AkuSilvenius]

Just faced this issue as well, using:

macOS Mojave 10.14.6 Python 3.7.3 (default, Mar 27 2019, 16:54:48) [Clang 4.0.1 (tags/RELEASE_401/final)] :: Anaconda, Inc. on darwin

[umamicode]

**just my experience, will delete if this causes a confusion hey guys, i solved this problem by solving the problem associated with the 'gcc' issue which is: error: command 'gcc' failed with exit status 1 in the error code. it seems that the latest version of macOS replaced stdlibc++ with libc++ (honestly, i'm not familiar with the terminology but..) so all we need to do is

but rather than (the captured image was trying to install korean nlp module btw) in the code, do whatever u were trying to do (i was trying pip install textacy myself)

this is the original blog post i've used. (KOREAN), but would be easier to google in your own languages https://lsjsj92.tistory.com/561

[simonsone]

I had the same problem on OSX Mojave. found just doing export MACOSX_DEPLOYMENT_TARGET=10.10 didn't work for me. However, I found that that running xcode-select --install worked for me, and afterwards I could install with pip3 install pyemd. I am on OSX Mojave. See https://github.com/wmayner/pyemd/issues/39

[wmayner]

I will have some time to look into the various installation issues in a few weeks. In the meantime I'm happy to review PRs.

same issue here

[NicolasNunezSahr]

Same issue here, using:

Debian GNU/Linux 9.12 (stretch) Python 3.7.3

[rpgoldman]

The solution by @umamiguy does not work for me. The problem seems to be -- as for many other libraries -- the python glue code for C++ expects to find headers in /usr/include, but this directory is not available because of Apple's SIP (no idea what that is). This causes problems with include <cmath> that ... I don't understand C++ well enough to grok.

This yields error messages like:

    In file included from pyemd/emd.cpp:566:
    In file included from pyemd/lib/emd_hat.hpp:95:
    In file included from pyemd/lib/emd_hat_impl.hpp:13:

    using ::fpclassify;
          ~~^

[112358fn]

As suggested here

This can be fixed by deleting /Library/Developer/CommandLineTools and running sudo xcode-select -s /Applications/Xcode.app

Not very elegant but I hope it helps.

[mschwedeler]

Had the same issue. For the system:

macOS: 10.15.7-x86_64 CLT: 12.0.31.1 Xcode: 12.4

after doing the following, I could install pyemd into a Python 3.8 virtual environment:

• Open the file cmath (in my case "/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/include/c++/v1").
• Locate the line #include <math.h>. In my case this is line 304.
• Replace with #include </Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/include/c++/v1/math.h>

Don't ask me why. See also here.
