Python: Python.h file missing

Question

I am using Ubuntu 16.04. I am trying to install Murmurhash python library but it is throwing error: command 'x86_64-linux-gnu-gcc' failed with exit status 1 . I looked on Internet and it is says that this error is due to missing python header files. So i did

sudo apt-get install python-dev  

but still the error is there. Is the error because i have Anaconda installed or what ? Can somebody help me as in how to rectify this error. Error is as follow :

running install
running build
running build_ext
building 'mmh3' extension
x86_64-linux-gnu-gcc -pthread -DNDEBUG -g -fwrapv -O2 -Wall -Wstrict-prototypes -fno-strict-aliasing -Wdate-time -D_FORTIFY_SOURCE=2 -g -fstack-protector-strong -Wformat -Werror=format-security -fPIC -I/usr/include/python2.7 -c mmh3module.cpp -o build/temp.linux-x86_64-2.7/mmh3module.o

The C++ part of the Python package seems to be faulty and as a result it does not compile. – Retrorse

@KlausD. But the same is running in Ubuntu 12.04 – Wrasse

The GCC got more strict over the years. You might be able to compile manually by setting the right flags to suppress the error. You can see them in [ ] at the end of the lines. – Retrorse

Answer 1

I just tried a docker container with ubuntu 16.04

apt-get update
apt-get install -y python-pip
pip install mmh3

That seems to be working. In your machine, you can just try.

sudo apt-get install -y python-pip
sudo pip install mmh3

With this you will be sure whether it is or not an anaconda problem with gcc.

I also checked anaconda with ubuntu 14.04 with the command pip install mmh3. It appears to be working too.
