Installation fails

[9daccad9]

Dear Community,
I've got a Problem during the Installation of timetrap. I want to install on debian "stretch" Linux.
First I installed with "apt-get" the package ruby. I think that was ok - here a Listing of dpkg:

roman@luna:~$ dpkg -l | fgrep ruby
ii  libruby2.3:i386              2.3.3-1+deb9u4                 i386         Libraries necessary to run Ruby 2.3
ii  rake                         10.5.0-2                       all          ruby make-like utility
ii  ruby                         1:2.3.3                        i386         Interpreter of object-oriented scripting language Ruby (default version)

ii  ruby-test-unit               3.1.7-2                        all          unit testing framework for Ruby
ii  ruby2.3                      2.3.3-1+deb9u4                 i386         Interpreter of object-oriented scripting language Ruby

Then I chanched to root and made the command as described:

root@luna:/home/roman# gem install timetrap
Fetching: sequel-4.43.0.gem (100%)

What did I made wrong? Do I have to download anything before using the command "gem
install timetrap"?

Can anyone help me?

You may need to install the dev packages with sudo apt-get install ruby2.3-dev (googling for "mkmf.rb can't find header files for ruby at /usr/lib/ruby/include/ruby.h" the first hit is that stack overflow page :) )

If that doesn't work, I often find these issues go away if you install ruby using rvm it seems to do a really good job of making sure all the dependencies are installed correctly.

Good luck - let us know what works!

I have installed the package ruby-dev, but still there are problems when trying to install timetrap:

Using rvm seems to difficult for me. Although I have some experience in linux, I have really no knowledge in ruby

[fdornak]

I had same problem, after installing
sudo apt install ruby-dev && sudo apt install libsqlite3-dev
installation of timetrap finished successfully

[9daccad9]

I have now also installed libsqlite3-dev, but there are still errors while installing timetrap ...
Cause I am no expert on ruby, so I will try another program ....
Thank you for your help!

[jerith666]

FWIW timetrap is packaged for nix; it will manage all the gory details of all the dependencies for you. Just install nix then nix-env -i timetrap.

[categulario]

dependencies have been upgraded, closing for now. Feel free to file a new issue or re-open this one if it happens again.

[JezzaHehn]

I've been using timetrap for years (fantastic program, thanks a million to all the devs involved) and have had this install issue a few times. Today I installed Ubuntu 20.04 and received a matching error and a similar experience — installed ruby-dev, libsqlite3-dev but it wasn't enough.

The fix for me was found at this stackexchange post.

sudo apt-get install ubuntu-dev-tools

and now the gem installed perfectly. It's a bit of a large package for this, but I anticipate this is a version-specific dependency issue. Hopefully this might save future users some searching. :)

hi @JezzaHehn, thanks for posting your solution
