Problem installing root_pandas with anaconda about root_pandas HOT 11 CLOSED

Hi, I have not encountered this problem. But it is certainly a strange one since your compiler is not finding basic things such as libm and libc :S. I would try and debug in that direction, meaning, where are these libraries in your setup ...

from root_pandas.

How are you installing root? Can you give a full list of the commands used to create the environment?

from root_pandas.

Thank you for spotting missing libraries, I will look at it.
I tried two things for installing ROOT, conda install -c chrisburr root and also installing it from NLesC, with the same result.

I also tried to install missing libraries with conda install gxx_linux-64 but I was then unable to find the packages installed in my env, only the root ones were found.

So, using conda install gxx_linux-64, I was able to install both root_numpy and root_pandas but when I try to import root_numpy (or root_pandas), I have the following error:

Do you have any hint ?
Thanks in advance,

from root_pandas.

Are you using pip install --no-binary root_numpy .... still?

• If not the problem is probably that root_numpy was compiled with a different ROOT version to the one you have installed
• If you did then you're picking up the ROOT libraries from the wrong place so you probably need to play with LD_LIBRARY_PATH

from root_pandas.

Yes I am.
I'm trying to install root only after installing gxx_linux-64, hoping it will use this compiler.

What does which gcc and gcc --version give you?

from root_pandas.

It gives me:
/home/renaudin/miniconda3/envs/cern/bin/gcc
gcc (GCC) 4.8.3 20140120 (prerelease)

My guess is that gcc and the conda cross-platform compiler are in conflict and the first one is picked for root then packages are compiled with the second.

from root_pandas.

I also tried to install your root without depencies, in hope that only x86_64-conda_cos6-linux-gnu-c++ will be used, but I'm stuck with the same error.
And if I don't install gxx_linux-64, I have a compiler error during the root_numpy installation.

from root_pandas.

Just to close the issue, I was able to install root_pandas getting back to Anaconda3-4.4.0.
I would be extremely interested if someone is able to make it work with latest anaconda but for the time being, this is all I need.
Many thanks for your help !

Thanks for reporting back. A few months ago (v5?) conda made major changes to the way gcc is used. It should be much better, but I'm not aware of anyone who has made an updated ROOT package yet. If anyone would like to I'd be happy to share my ideas for making it in a more maintainable way.
