I have the following environment:

Linux Mint17.1 which comes pre-installed with python 2.7.6.

I setup an altinstall for python 3.3.5

Using python 3.3 I created a virtualenv

I am trying to install TA-Lib in the virtual env but am not having any success.

If I try to install with:

./easy_install TA-Lib

I get the following error:

                        ^

If I try to install with:

./pip install https://github.com/mrjbq7/ta-lib/archive/TA_Lib-0.4.8.tar.gz

I get the following error:

compilation terminated.

/tmp/pip-rxvyyh-build/setup.py:49: UserWarning: Cannot find ta-lib library, installation may fail.

 warnings.warn('Cannot find ta-lib library, installation may fail.')

error: command 'gcc' failed with exit status 1

So basically both approaches result in a final error of:

command 'gcc' failed with exit status 1

I have no problem installing other packages such as numpy, pandas, matplotlib etc in the virtualenv. It is just TA-Lib that is not working.

    Looks like you need to make sure the native packages are installed first, and that the include files and libs can be found by gcc. Perhaps this will help: https://tradingprogram.wordpress.com/2014/05/04/installing-ta-lib-ubuntu/ – bimsapi Apr 29 '15 at 14:40

You don't have installed underlying ta-lib library. You can find more info on the project site https://github.com/mrjbq7/ta-lib :

Sometimes installation will produce build errors like this: func.c:256:28: fatal error: ta-lib/ta_libc.h: No such file or directory compilation terminated.

This typically means that it can't find the underlying TA-Lib library, a dependency which needs to be installed.
