error on install

[andrewcz]

hi all, Trying to use this awesome software :).

getting the below error.

Hi @andrewcz If you re-run the CMake step of the build process, the output log will show whether it has found an install of OpenCV (and which version). It looks like it hasn't found it and hence produced this error. Can you let me know how you installed OpenCV?

[andrewcz]

to be honest, i having trouble installing opencv. its coming up with errors. If you have some ideas that could help i would sincerly appreciate it :). Many thanks, Andrew

[andrewcz]

so it look like it build now trying to build the python library

Hi @andrewcz Good to hear you have overcome your OpenCV lib install issue. This new issue relates to using the older version 2 of SWIG. We currently use version 3. I double checked in a Mint 18.2 VM and that is the case. Although the default Aptitude (apt) install for swig is actually version 3. If you don't require version 2 of SWIG for other projects you can use the following bash commands to change from v2 to v3 (assuming you are using Mint 18.2):

sudo apt purge swig2.0
sudo apt autoremove
sudo apt install swig

If you do require version 2 of SWIG for other projects, there maybe a local work around that could be made with EOgmaNeo to help you get the Python bindings built.

cheers, i am having trouble with the swig install i am using linux 17.3 and trying to install swig from scatch.

[rcrowder]

Make sure that you delete the build/ directory when re-running setup.py

[andrewcz]

got the above. the trouble is installing swig. when i go swig -version, nothing comes up.

[andrewcz]

http://www.linuxfromscratch.org/blfs/view/8.1/general/swig.html. i am following the above instructions about how to install it

[rcrowder]

The make install ... step from those instructions should have placed it in a common location (as long as sudo was used to run make install as root).

using sudo make install ...

Thanks for posting the screen shot. It shows that you've installed Swig into /usr/local/ Which is fine, but on a Mint VM, even with the PATH searching in /usr/local/bin for Swig, it can't find in.. One thing that you can do in your case is to create a soft-link to Swig using:

sudo ln -S /usr/bin/swig /usr/local/bin/swig

[andrewcz]

[rcrowder]

Oops, sorry that should have been a lower-case -s, i.e.

sudo ln -s /usr/bin/swig /usr/local/bin/swig

cheers for your help Richard :) Best, Andrew

[andrewcz]

[andrewcz]

so i was able to install the python module. but for some reason it did not find it on the run. Best, Andrew

[rcrowder]

Hi @andrewcz Glad to hear that you have the library and bindings building. At first I though this issue related to a shared vs statically linked EOgmaNeo C++ library. But after trying to recreate the issue inside Linux Mint (using miniconda3) I haven't so far been able to see the same issue as yourself. An import error like this can also point to the C++ library being linked to one version of Python (v2 for instance), while trying to import it into another version (such as v3). This may happen if after running python setup.py install it is re-run after installing a different version of Python, and the EOgmaNeo/Python/build directory is not deleted between runs of setup.py. Locally the only change I needed to make to the Python build process is to allow it to find a miniconda3 installation. That required one line in the Python/CMakeLists.txt to be duplicated to the following (inserted after line 128 [1], note the first four spaces of indentation):

string(REGEX MATCH "miniconda" ANACONDA_PYTHON_FOUND "${_CONDA_OUTPUT}")

Even with that additional line in the CMakeLists.txt file, the Python bindings built and the sine wave example ran fine for me. Now that you have the appropriate dependencies installed, the only thing I can suggest is to delete and re-clone the repository, pip uninstall eogmaneo, and try the setup.py install again.

[andrewcz]

no worries richard, i think im just going to reinstall everything and see how i go. I am pretty sure its an issue with my computer. Appreciate all the help and support though :) best, Andrew

[rcrowder]

@andrewcz I'll close this issue for now. Create a new issue if you continue to have dependency problems during installation.
