Dependencies on Linux Distribution

[gerhswitsiem]

I use the package in a r docker container (r-ver). To successful install the package the following packages are necessery:

• "libcurl4-openssl-dev"
• "libssl-dev"
• "curl"

Please add this dependencies in your documentation.

Technically, I agree with you. However if we follow the dependencies we see that {influxdbr} imports {jsonlite} which imports {curl} which lists the required packages. So the issue is rather the installation of {curl}, isn't it?

[gerhswitsiem]

This could be the issue. But if we know this problem and the dependencie chain require this tools, it should be a sign in the documentation that there could be some struggles.

Thank you for your review on this case.

IMHO there is not need to add this to the system requirements. The error message on the install has sufficient clues on how to solve the problem.

Ok - then I think we can close this issue. If somebody else have some trouble with this, he can find this issue and get the solution.
Thanks for your affort.

@gerhswitsiem Agreed. Thanks!
