How to install in virtualenv? #760

Closed mgiaco closed 7 years ago

mgiaco commented 7 years ago

Hello,

Can someone help me on how to install mraa in virtualenv? I have already installed the lib on my BBB and it seems to work. But now i would like to install it in a virtualenv for that i activated the virtualenv - rebuild it and run a make install .. But if i try to run a test app from the virtualenv mraa is not found. So I am doing anything wrong.

thx

arfoll commented 7 years ago

I think if you activate the virtualenv and then build mraa (make sure to rerun cmake from a clean build dir) it should got to the right place. Check the cmake cache to see the PYTHON2_PACKAGES_PATH and PYTHON3_PACKAGES_PATH are good and override them with your virtualenv packages path if wrong. Another option is just to copy the mraa.py and _mraa.so directly to the packages path?

mgiaco commented 7 years ago

So I followed your advice. The path was wrong I changed it to the virtualenv path but I does not work. So I have to copy it by hand. By the way mraa also works with python3 - right?

arfoll commented 7 years ago

so python3 & python2 binaries are different but yes mraa works with both

do you have the output of cmake, cmake -LA and VERBOSE=1 make install? might be able to work something out.

If you need anything more please do not hesitate to contact me. cheers mathias

alext-mkrs commented 7 years ago

Here's the specific reason - it doesn't find the Python 3 libs, thus builds only Python 2 bindings:

-- Found PythonInterp: /home/debian/pywork/venv/bin/python2.7 (found suitable version "2.7.9", minimum required is "2.7") 
-- Found PythonLibs: /usr/lib/arm-linux-gnueabihf/libpython2.7.so (found suitable exact version "2.7.9") 
-- Found PythonInterp: /usr/bin/python3 (found suitable version "3.4.2", minimum required is "3") 
>>>>>> -- Could NOT find PythonLibs (missing:  PYTHON_LIBRARIES PYTHON_INCLUDE_DIRS) (Required is exact version "3.4.2")

You do have them installed, don't you?

mgiaco commented 7 years ago

Yes I only use python2.7 now but I will switch to python3. Is it a good idea to install booth on the same image. Do I really need the exact version 3.4.2? because my plan was to use this one here http://layers.openembedded.org/layerindex/recipe/23823/ ... Okay here is this version available: http://recipes.yoctoproject.org/rrs/recipedetail/297/

What do you think?

arfoll commented 7 years ago

There "should" be no issue using any python3 to build. But we don't test that scenario so there may be a few weird ones. Having both on the same image is really no issue, pretty much all distros do this.

Btw you can build mraa in a recipe too, or you can build it with your OE toolchain with our cmake/Toolchains/oe-sdk_cross.cmake. See the docs/building.md for more details

mgiaco commented 7 years ago

Okay I will try that, many thanks.
