Trying to install the package soegtk. I am running linux mint 17 with the latest (as of Feb. 28) haskell platform and cabal-install. I did install gtk2hs-buildtools and put the .cabal/bin in my path. Cannot install soegtk: Failed to install glib-0.12.5.4 cabal: Error: some packages failed to install: cairo-0.12.5.3 failed during the configure step. The exception was: ExitFailure 1 gio-0.12.5.3 depends on glib-0.12.5.4 which failed to install. glib-0.12.5.4 failed during the configure step. The exception was: ExitFailure 1 gtk-0.12.5.7 depends on glib-0.12.5.4 which failed to install. pango-0.12.5.3 depends on glib-0.12.5.4 which failed to install. soegtk-0.12.1 depends on glib-0.12.5.4 which failed to install. Confession: I abandoned Haskell two years ago because of frustration with cabal and hackage. I decided to get back to the language today, and to start with Haskell School of Expression. I immediately run into the problem that the first thing I try to install with cabal does not work. Thanks for any help. Please tell me things are not just as bad now as they were when I left ;-) - DJP -

New subject: trying to install libraries for Haskell School of Expression

We have sandboxes now, which (I think) weren't there 2 yrs ago. Try this: $ mkdir hse # Directory for Haskell school of expression $ cd hse $ cabal sandbox init # Create a new sandbox $ cabal install gtk2hs-buildtools # Install gtk2hs-buildtools inside sandbox $ export PATH=".cabal-sandbox/bin:$PATH" # Add the binaries installed in (current directory's) sandbox to $PATH $ cabal install gtk # Install gtk (and anything else you need) The above works in my case. Also, if you have a lot of packages installed in "~/.cabal", then I recommend that you remove them and install them in sandboxes where they are actually required. Manually, you'd do it as follows: $ mv ~/.cabal/packages ~/temporary_package_storage # Long name to avoid clash, save downloaded package sources $ rm -rf ~/.ghc ~/.cabal # Remove all packages, and ghc's knowledge of them $ mkdir ~/.cabal # Make a new ~/.cabal directory $ mv ~/temporary_package_storage ~/.cabal/packages # Reinsert the saved downloaded package sources For more info, look here: https://www.haskell.org/cabal/users-guide/installing-packages.html#developin... Also, after some time it becomes natural to deal with cabal. For example, I have that export line in my .zshrc. Thus the sandbox residing in current directory is always in my path. Also, a shell function that you may want to use. cabal-reset () { if [[ ! -d ~/.cabal-packages ]] ; then # If backup does not exist mv ~/.cabal/packages ~/.cabal-packages # Make a backup fi rm -rf ~/.ghc ~/.cabal # Nuke everything mkdir ~/.cabal # Create new ~/.cabal ln -s ~/.cabal-packages ~/.cabal/packages # Symlink backup to ~/.cabal/packages } Hope this helps.

Do you have the devel libraries needed by gtk installed? cabal cannot install them for you, and the runtime libraries are not sufficient. You'll want libcairo2-dev for this, and others for other gtk components (notably libgtk-3-dev but there will be others as well). -- brandon s allbery kf8nh sine nomine associates allbery.b@gmail.com ballbery@sinenomine.net unix, openafs, kerberos, infrastructure, xmonad http://sinenomine.net

Brandon: Thanks. I did have to install some gtk libraries. I am also working in a sandbox now. This moved things ahead somewhat. But I am getting this now from 'cabal install soegtk': Graphics/SOE/Gtk.hs:94:18: Could not find module `System.Time' It is a member of the hidden package `old-time-1.1.0.1'. Perhaps you need to add `old-time' to the build-depends in your .cabal file. Use -v to see a list of the files searched for. Failed to install soegtk-0.9.12.2 I have forgotten anything I once knew about using cabal. I apologize for not learning how to deal with the above on my own, but I am hoping to get over this hump as quickly and painlessly as possible so I don't lose my momentum getting back to Haskell. So, can anyone give me a hint how to fix the above? Best, - DJ - On 15-03-01 02:29 AM, Brandon Allbery wrote:

That is actually all you have to do: in the cabal file of your package you have either a 'library' section or an 'executable' section. These should have a field 'build-depends' simply add 'old-time >= 1.1 && < 1.2' their. See for example the cabal file of the lens package: https://github.com/ekmett/lens/blob/master/lens.cabal If you don't have a cabal file you can initialize one via 'cabal init' or simply install the package in the sandbox via running 'cabal install old-time-1.1' in your sandbox, i.e. the directory you ran 'cabal sandbox init' beforehand.

That would be an out of date [program referring to the old time component (which wasn't very good, but was in base so didn't need dependencies). Just adding a dependency on old-time to the cabal file should be sufficient to get it to work. I don't know why soegtk hasn't been updated to either reference that package or use the modern time package. -- brandon s allbery kf8nh sine nomine associates allbery.b@gmail.com ballbery@sinenomine.net unix, openafs, kerberos, infrastructure, xmonad http://sinenomine.net

Yeah. I think there are a lot of us out there. I won't rant (much) here, because I hope to get some help from time to time. Alienating people is not a good way to get help. But: There are many things I like about the language, but I have always been perplexed by the haskell ecosystem in a couple of ways. However good and/or interesting a language might be, it is not possible to do meat and potatoes development unless there is a good supply of packages/libraries. My first problem was that I often just could not get stuff to install. The second problem was documentation. I hope it has improved a bit. I was always flabbergasted at the (apparent) belief that a few lines of API documentation coughed out by haddock are enough. But that's all there was in a lot of cases. That, and "refer to xxxx research paper" and "figure it out from the types". Hah. Any math paper that consisted of just the equations sorted in alphabetical order would not be well received, I think. I really admired that fact that Michael Snoyman wrote a book about Yesod. For all I know he may not have kept the book up, but at least he realized that people needed an explanation of how to use his software. Well, back to work. I am going to give haskell another try for sure. It's just too tempting to give up on. If it doesn't work, the next stop will be sml or ocaml.

What does that do for me within LTS confines? I know Hoogle, but I don't understand what you mean by "they run a hoogle for the exact version, with every library." ...I just want to understand so I can be as excited as everybody else right now! LOL :) On 2 March 2015 at 12:34, Julian Birch wrote:

I was always flabbergasted at the (apparent) belief that a few lines of API documentation coughed out by haddock are enough. But that's all there was in a lot of cases. That, and "refer to xxxx research paper" and "figure it out from the types". Hah. Any math paper that consisted of just the equations sorted in alphabetical order would not be well received, I think.

I really admired that fact that Michael Snoyman wrote a book about Yesod. For all I know he may not have kept the book up, but at least he realized that people needed an explanation of how to use his software.

Well, back to work. I am going to give haskell another try for sure. It's just too tempting to give up on. If it doesn't work, the next stop will be sml or ocaml.

Best,

Confession: I abandoned Haskell two years ago because of frustration with cabal and hackage. I decided to get back to the language today, and to start with Haskell School of Expression. I immediately run into the problem that the first thing I try to install with cabal does not work.

It is the same reason I have stopped using it. It's a real shame. Those with better education and understanding than mine should be concerned that the uptake of the language is stunted by its package manager.

I love Haskell. I have taught myself (the beginnings at least) of group theory just to better comprehend the mindset of monads. For that alone I am glad I learned Haskell as it has rekindled my interest in maths!

...
Thanks for any help. Please tell me things are not just as bad now as they were when I left ;-)

This mail seems to indicate to me that "cabal hell" is here for some time to come...

New subject: trying to install libraries for Haskell School of Expression

Thanks for the help, guys. Life is short. I have spent the better part of two days trying to get soegtk to install. No luck. Same shit as when I left haskell behind two years ago. I'm out. - DJ - On 15-02-28 11:40 PM, DJ wrote:

Trying to install the package soegtk.

I am running linux mint 17 with the latest (as of Feb. 28) haskell platform and cabal-install.

I did install gtk2hs-buildtools and put the .cabal/bin in my path.

Cannot install soegtk:

Failed to install glib-0.12.5.4 cabal: Error: some packages failed to install: cairo-0.12.5.3 failed during the configure step. The exception was: ExitFailure 1 gio-0.12.5.3 depends on glib-0.12.5.4 which failed to install. glib-0.12.5.4 failed during the configure step. The exception was: ExitFailure 1 gtk-0.12.5.7 depends on glib-0.12.5.4 which failed to install. pango-0.12.5.3 depends on glib-0.12.5.4 which failed to install. soegtk-0.12.1 depends on glib-0.12.5.4 which failed to install.

Confession: I abandoned Haskell two years ago because of frustration with cabal and hackage. I decided to get back to the language today, and to start with Haskell School of Expression. I immediately run into the problem that the first thing I try to install with cabal does not work.

Thanks for any help. Please tell me things are not just as bad now as they were when I left ;-)
