issue in finding python in the sdk of tda4-evm

Hi Aneesh,

Can you please elaborate on the problem statement further?

Does installing any of these dependencies on the host help you to move further? I do see that the numpy other python modules can be installed by adding it to the target filesystem using the methods that you are already familiar with.

I believe that I'm missing some information to help understand your problem clearly. If the above suggestion is not useful, please consider expanding the details further so that I can help you out.

Hi karthik,

I have elaborated the problem statement below.

Aneesh,

I think I understand the problem. Can you please help me with an example public repository using which I can experiment the solution to test and provide to you? 

Or we can work offline and certainly have a meeting to go over this. Let me know separately if you think a meeting is easier.

Regards

Karthik

Hi karthik,

As per the discussion in the yesterday meeting i have shared the steps and sample application to you through an email for reproducing the problem on your side.I am attaching the steps and sample application below also for tracking.

1.crete a new sdk_exp folder and untar the sdk arago-core-psdkla-bundle-j7-evm.tar.xz file in sdk_exp folder using below commands:

$mkdir sdk_exp

$cd sdk_exp

$tar -xvf arago-core-psdkla-bundle-j7-evm.tar.xz

2.Now run the below script to install the sdk.

$./sdk-install.sh

3.Now untar the python-test in the sdk_exp folder using below command.

$tar -xvf python_test.tar.xz

4.Source the sdk environment for cross-compiling using below command.

$source linux-devkit/environment-setup

5. Execute below commands inside the python_test folder.

$mkdir build

$cd build

$cmake ..

$make

Thanks and Regards,

Aneesh,

Thanks. I have been able to recreate the issue. I'm looking into the options for resolving the same.

In the meanwhile, if you have any other suggestions to get me upto speed with where you are.

Hi Aneesh,

We are now in discussions about this patch: http://arago-project.org/git/?p=meta-arago.git;a=commitdiff;h=a3f404323a3be6bc1902a6e167c2eae288f2eb2e, reverting this patch seems to get us a bit further.

Your test doesn't use numpy so you can uncomment the numpy dependency and see if you can get the tests to be compiled and working.

Can you try this at your end and let us know your results?

Regards

Karthik

Hi karthik,

Last week, we also found the same thing which is mentioned in the patch and I have commented the python binaries removing step like below from the ~/meta-arago-extras/recipes-core/meta/meta-toolchain-arago.bb file and tested the sdk with sample test application.

# Remove python binaries
# gdb links with libpython and loads core modules, which bundled with binaries
#rm -rf ${SDK_OUTPUT}/${SDKPATHNATIVE}${bindir_nativesdk}/python*

The cmake is able to find the python Interpreter and Development packages but still have the issues in finding the NumPy packages. As the numpy is also one of the main required package, we need the support to fix for the numpy issue.

Thanks and Regards,

Aneesh

Hi Aneesh,

I suggest that we start engaging in the python3 related forums and understand the dependency here.

I'm trying to discuss internally with our experts also, will keep you posted if I find anything. I have already tried include numpy with the below patch and that didn't seem to help:

diff --git a/meta-arago-extras/recipes-core/packagegroups/nativesdk-packagegroup-arago-tisdk-host.bb b/meta-arago-extras/recipes-core/packagegroups/nativesdk-packagegroup-arago-tisdk-host.bb

Hi Aneesh,

As mentioned in the previous post, we have included the patches to add the python and numpy into the nativesdk.

With that we have seen the above test case passing after commenting out the numpy dependency.

So, with regard to including the python-numpy package, it is still an unknown and we are not sure what else is missing.

 $ find . -name numpy*

./sysroots/x86_64-arago-linux/usr/lib/python3.8/site-packages/numpy

./sysroots/x86_64-arago-linux/usr/lib/python3.8/site-packages/numpy/core/include/numpy

./sysroots/x86_64-arago-linux/usr/lib/python3.8/site-packages/numpy/core/include/numpy/numpyconfig.h

./sysroots/x86_64-arago-linux/usr/lib/python3.8/site-packages/numpy/distutils/numpy_distribution.py

./sysroots/x86_64-arago-linux/usr/lib/python3.8/site-packages/numpy/distutils/__pycache__/numpy_distribution.cpython-38.pyc

./sysroots/x86_64-arago-linux/usr/lib/python3.8/site-packages/numpy-1.17.4-py3.8.egg-info

.. etc 

We have a suspicion that it may be related to the cmake usage itself and since we are having an offline conversation on cmake, I suggest we close this thread here and continue in a consolidated thread. 

This also needs to be worked with the python community.

Karthik
