I'm using anaconda 64bits on a manjaro distribution. I created a python3.6 enviroment using conda create -n tensorflow python=3.6 anaconda.
I also installed pip install tensorflow-gpu==1.12 and conda install cudnnif that matters.
On my original python 3.7 outside of anaconda (/usr/bin/python3) it installs fine, but when I enter the virtualenv by conda activate tensorflow, and try to install by pip install regex==2017.4.5 it yelds an error.
Other versions of the package seem to be getting the same error, it is not version specific.
See the error message below:

Some things I noticed above:
Upon building, the error message pointed out
file not recognized: file format not recognizedSomething called "ld" exited a fail status on the building process
collect2: error: ld returned 1 exit status. I suppose this is just to signify that something went wrong while builind on /run/ or /usr/temp, but it may be helpful.
I don't actually believe it's a problem with gcc, since other packages install fine.
I also don't believe it to be an error of system-wide dependencies, because outside of the virtualenv everything works fine.
And please keep in mind: I am using a manjaro, arch distributions don't have -dev or -devel packages (e.g. python-devel) to install separatelly. Normally those come included with the original package (i.e. python or python3).
Thanks for any help :).
