Building error nupic.core in Ubuntu 16.04 LTS

but I really do not know how to uninstall those eggs.
Should I remove them from my harddisk?

I really don’t know. It looks like you installed them with pip at some point in the past. Maybe you can review your shell history for pip commands? I don’t understand how pip decides where to put stuff. It depends on user permissions and the --user flag. You’re hopefully not using sudo for these commands…

I am going to sleep now (it is midnight in Germany), maybe I have some ideas tomorrow morning. Best thanks for your support.

I used the following methods for solving problems:
1- delete the directory “nupic.core” and “nupic.research” for solving "eggs"
2- upgrade pip 8.1.1 into pip 8.1.2
3- clone nupic.core and install
pip install https://s3-us-west-2.amazonaws.com/artifacts.numenta.org/numenta/nupic.core/releases/nupic.bindings/nupic.bindings-0.4.4-cp27-none-linux_x86_64.whl
pip install nupic
Please note that I have to use “sudo pip install …” due to written permission into python 2.7 directory.
4- build nupic.core
Once again, I have the same error as before:
/usr/bin/ar: invalid option – ‘R’

I think, it seems to be a problem with CMake.
Can anyone help me?
Thanks

In the meantime, 2 steps for nupic installation were successfully done

pip install https://s3-us-west-2.amazonaws.com/artifacts.numenta.org/numenta/nupic.core/releases/nupic.bindings/nupic.bindings-0.4.4-cp27-none-linux_x86_64.whl
pip install nupic

After that I tried to build the nupic.core again, and had the same error as before.
After very long debugging, I found out I have to modify the script “libtool” in the directory
./nupic.core/build/scripts/ThirdParty/Build/Apr1StaticLib at the line 147 as follows:

#AR="gcc-ar RANLIB=gcc-ranlib"
AR="gcc-ar"

After modifying the file “libtool” I can build all the thirdparty SW.
But I am not sure if there is any further problem after this modification.

Can you explain this effect?

By building nupic.core, we have additional errors

Are those errors known by you?
Best thanks

I’m not sure I’m going to be able to help you until I’ve done a complete installation test on Ubuntu 16, and I won’t have time to do that for awhile. My apologies :frowning:.

@rhyolight
No problem that you do not have time for it.
Now, I find out a systematical solution for this building problem:
In the file: CommonCompilerConfig.cmake at the line 313,
please change:
set(EXTERNAL_STATICLIB_CONFIGURE_DEFINITIONS_OPTIMIZED_STR “AR=gcc-ar RANLIB=gcc-ranlib”)
into
set(EXTERNAL_STATICLIB_CONFIGURE_DEFINITIONS_OPTIMIZED_STR “AR=gcc-ar”)

Best regards
