how to install libreoffice on heroku - heroku

I am trying this http://documentcloud.github.io/docsplit/ on heroku which require libreoffice to be installed on heroku to cut docs in to pdfs.
Is there any build pack available for this or how to create a build pack for this

I was looking for an answer to this also, so I ended up building my own LibreOffice buildpack: https://github.com/rishihahs/heroku-buildpack-libreoffice

Imagemagick buildpack for Heroku-18 stack

I am upgrading my Heroku tech stack to Heroku-18 from heroku-16. I am getting error while deploying beacause of un supported Imagemagic build pack for Heroku-18. Is there any option to use another Imagemagic version that supports in Heroku-18 stack.thanks in advance.
Apparently Heroku 18 already comes with Imagemagick, so you no longer need the separate buildpack.

if you are installing Redmine in your local system which has OS Windows 10, you no need to install all the required set of Softwares separately, you can go and download the Bitnami Redmine here
the download is an installer you can easily install all the software includes Database aswell.
I think this will helps you.
I do not know why you are trying to install redmine the ways you quote usually first check if it is already installed via command prompt and write, gem list.
If not installed, gem install 'redmine' or gem update 'redmine'
I would do a check to see if redmine is actually still an active gem.

I can't get libvips to compile on heroku

I have spent days trying to get the outdated libvips buildpacks working on Heroku. I finally got https://github.com/wwarne/heroku-buildpack-vips to work, but it doesn't seem to have been compiled with libpoppler, so I don't have pdf support which I need. I have tried repeatedly to run the build.sh file, but I have not been successful.
Does anyone know of a way to get libvips installed on heroku with poppler pdf support without adding 200mb to my slug by using apt-get install?

Heroku toolbelt installation not working

I have Heroku installed in my machine and I can check the version just for verification as you can see in the picture.
So now, I want to install heroku toolbelt but I am having problems to do so.
Everytime I go to the link: https://toolbelt.heroku.com/windows. I get redirected to this link:https://devcenter.heroku.com/articles/heroku-cli which is just to install heroku.(which I already have installed).
Is there another way around I can use to intall toolbelt?

Upgrading ImageMagick on Heroku

Is this possible? If so how I do upgrade from Version XXX to Version XXXX?
I can't seem to find any docs on it.
Thanks!
No.
Heroku maintain imagemagick as part of the service so you'd have to convince them to upgrade it across the platform.
The way to upgrade ImageMagick on heroku now is by using a 'buildpack'.
If you search through the buildpacks on heroku: https://elements.heroku.com/search/buildpacks?utf8=%E2%9C%93&q=imagemagick you can see there are quite a few dedicated to updating ImageMagick.
You can install a custom buildpack by using the following command line call:
$ heroku buildpacks:set https://github.com/heroku/heroku-buildpack-erlang
Buildpack set. Next release on random-app-1234 will use https://github.com/heroku/heroku-buildpack-erlang.
Run `git push heroku master` to create a new release using this buildpack.
More information about buildpacks can be found here: https://devcenter.heroku.com/articles/buildpacks
