I have met a problem ,when i run ‘’./products/olympe/linux/env/postinst’’ according to the installation steps.
the problem is “unable to locate libclang-11-dev”. And this error will leads to further error bei ‘’
$ ./build.sh -p olympe-linux -A all final -j’
I have tried the Installation both in Ubuntu 18.04 and Debian10.
I thought the real problem is clang-11 is too new and libclang-11.dev are not perfekt avaliable.
In Ubuntu is libclang-11.dev only avalible for groovy(which is new coming version).
In Debian is libclang-11.dev only avalible in some unstable or experimental sources. It will also leads to some new problems.
Have someone resolved this problem?
Running into the same issue here. Bellow is the error I am getting:
$ ./products/olympe/linux/env/postinst >>> ... >>> Reading state information... Done >>> E: Unable to locate package libclang-11.-dev >>> E: Couldn't find any package by glob 'libclang-11.-dev' >>> E: Couldn't find any package by regex 'libclang-11.-dev'
Its weird, I ran through this installation a few weeks ago, and didn’t have this issue. I compared the
postinst script from my previous run and my latest one and they are identical, so I don’t believe its something on Olympe’s side. Digging into the issue I believe the error comes from the following line in the
CLANG_VERSION=$(/usr/bin/python3 -m pip show clang |grep '^Version' |cut -d' ' -f2 |cut -c1-3)
$ /usr/bin/python3 -m pip show clang |grep '^Version' >>> Version: 11.0
As we can see it returns version 11, but that version is not available on Ubuntu 18.04. I will update this post if I find anymore.
Okay found a working solution (not sure if it’s the best one, but I just tested it and it works for me).
Run the commands
# Install correct version of clang $ sudo python3 -m pip uninstall clang $ sudo python3 -m pip install clang==184.108.40.206 # Rerun the process that used to throw the error $ cd code/parrot-groundsdk $ ./products/olympe/linux/env/postinst
I did this whole install a few weeks ago on another machine without issue. From my previous post I realized that my new install has the clang version 11 installed:
$ python3 -m pip show clang >>> Name: clang >>> Version: 11.0 >>> Summary: libclang python bindings >>> ...
Running the same command on the machine where it worked I get the following:
$ python3 -m pip show clang >>> Name: clang >>> Version: 220.127.116.11 >>> Summary: UNKNOWN >>> ...
I am still not quite sure why or when clang version 11 is installed in the process. However to fix it I simply uninstalled version 11 and reinstalled version 18.104.22.168 using the commands:
# Remove the current clang $ sudo python3 -m pip uninstall clang # Install the correct version of clang $ sudo python3 -m pip install clang==22.214.171.124 # Rerun the process $ cd code/parrot-groundsdk $ ./products/olympe/linux/env/postinst
thanks a lot.I have also solved this Problem by modidy postinst file to install lower version of clang.
I think in debian it is safer to install clang6. In Ubuntu it is okay to install clang10
