When trying to install clckwrks, I get the following error after a couple cabal install tries:
~/Progs/clckwrks/clckwrks$ cabal install
Resolving dependencies...
Configuring happstack-server-tls-7.1.0...
cabal: Missing dependency on a foreign library:
* Missing C library: cryptopp
....
Why can I not find this library in the repositories? Is it the Crypto++ from cryptopp.com? Oddly enough there's no mention of this on the getting started guide at http://clckwrks.com/page/view-page-slug/3/get-started .
Yes, you need to install crypto++. If you'll get the same error after installing this lib, look at this question.
BTW, actually, the problem is in happstack-server-tls, not in clckwrks, so they haven't mentioned it.
Update
On server running you can get error about ssl/localhost.key and ssl/localhost.cer. In this case - look for the answer here.

I've been trying to compile the Kadena chainweb-node project from source (via the docs found here) in a docker container running the arm64v8/ubuntu base image on an Apple M1 host machine and I keep getting errors. Thanks to the super helpful folks in the #haskell IRC channel, I've made it over a number of small hurdles, but the build still fails with:
Undefined symbol: ossl_sha3_512_functions
I can not find any resources on how to fix this but one of the #haskell community members informed me that these symbols are not provided by the openssl 3.0 API. That person created an issue here: https://github.com/larskuhtz/hs-hashes/issues/14
I've found that I can use the docker base image haskell:8 which comes preinstalled with ghc, cabal, and openssl 1.1.1 to cabal build chainweb-node successfully using a slightly different set of apt-get dependencies. However, when trying to cabal install the binaries so that I can run chainweb-node, I get:
Failed to build chainweb-2.14.1. The failure occurred during the configure
step.

I've tried cabal install criterion and the other missing deps, one by one, but the cabal install gives me the same errors.
Can someone tell me what I'm doing wrong and help me get a working chainweb-node binary built from source and installed using docker?
So I am trying out a Haskell developing with the following IntelliJ plugin:
https://plugins.jetbrains.com/plugin/7453?pr=
GitHub page here:
https://github.com/rikvdkleij/intellij-haskell
The only issue I have with this plugin is as follows: When I try to run my code I keep getting this error message saying that the Cabal Configure Failed. NOTE: Before anyone asks, I have told IntelliJ that GHCs is located at usr/bin/ghc. And yes, I am running Ubuntu-MATE 16.04
Why am I getting this error, and is there a way to fix it?
EDIT: Cabal --version returns the following output:
cabal-install version 1.22.6.0
using version 1.22.5.0 of the Cabal library
Running Cabal Configure, from terminal, in my project directory results in the following output:
Resolving dependencies...
Configuring Test-0.0.1...
cabal: At least the following dependencies are missing:
doctest -any
And IntelliJ knows my cabal data path to be:
/home/avi/.cabal
I'm trying to cabal install binary-strict and I get this error:
src/Data/Binary/BitBuilder.hs:205:37:
Ambiguous occurrence `unsafePerformIO'
It could refer to either `Foreign.unsafePerformIO',
imported from `Foreign' at src/Data/Binary/BitBuilder.hs:38:1-14
or `System.IO.Unsafe.unsafePerformIO',

(and originally defined in `GHC.IO')
Failed to install binary-strict-0.4.8.1
cabal: Error: some packages failed to install:
binary-strict-0.4.8.1 failed during the building phase. The exception was:
ExitFailure 1
I'm running ghc 7.6.3. If it's relevant, I have binary-0.7.2.3 installed too.
As written, binary-strict only works for base >= 4.7. GHC 7.6.3 uses base = 4.6.* so it will not work. You should file a bug with the maintainer and work around the issue by adding hiding (unsafePerformIO) to the import Foreign line of the file in question.
I only just found out about this. It is now fixed. Also I have listed the git repo in the package details so you can now raise issues and I will know about them. Thanks to Thomas for suggesting the fix.
I'm currently trying to use pandoc (as a Haskell module, not as a program) to convert MediaWiki text to other formats.
Let's assume this program:
import Text.Pandoc.Readers.MediaWiki
main = do print "foo"
When using runghc to run it, I get the following error message:
pandock.hs:1:8:
Could not find module `Text.Pandoc.Readers.MediaWiki'
Use -v to see a list of the files searched for.
My first assumption was that pandoc was either not installed or incorrectly installed. Therefore I reinstalled it with --force-reinstalls
$ cabal install pandoc --reinstall
[...]
In order, the following will be installed:
pandoc-1.12.3.1 (reinstall) changes: old-time-1.1.0.1 added
[...]

The output of runghc -v pandock.hs is quite long, I assume the relevant part is:
*** Chasing dependencies:

Locations searched:

However, both ~/.cabal/lib/x86_64-linux-ghc-7.6.3/pandoc-1.12.3.1/Text/Pandoc/Readers/Mediawiki/MediaWiki.hi and ~/.cabal/bin/pandoc exist. How can I make GHC properly recognize the cabal-installed package?
Any help will be appreciated!
When trying to reproduce this issue on other computers, only 2 out of 5 computers had this issue. On both of them I installed cabal packages in about the same way and order.
In retrospect I assume this issue arose because of some broken packages wreaking havoc:
$ ghc-pkg check
There are problems in package feed-0.3.9.2:

The following packages are broken, either because they have a problem

yesod-test-1.2.1
Note that neither pandoc nor yaml (I installed it after asking the question and had the exact same issues as with pandoc) are listed there.
For users also having a similar problem, please ensure:
The package is installed and you're not inside any sandbox where the package is not installed.
In the directory where you're executing the test script, ensure that there is no Text/Pandoc folder (or equivalent, depending on the package causing the problem
Run your test script with runghc -v to check if it searches the proper directory
ghc-pkg list lists your package as installed, and no packages are broken (use ghc-pkg check to check)
I solved my problem by renaming ~/.cabal and ~/.ghc. Note that I did this lacking a proper solution, I think you should only do this as a last resort.
I want to use Yesod web framework with yesod-auth-oauth, but I encountered a dependency problem while cabal-dev install:
/Users/kenta/myapp/oryza% cabal-dev install
Resolving dependencies...
cabal: cannot configure yesod-platform-1.0.2. It requires data-default ==0.4.0
For the dependency on data-default ==0.4.0 there are these packages:
data-default-0.4.0. However none of them are available.
data-default-0.4.0 was excluded because authenticate-oauth-1.3.0 requires
data-default ==0.3.*
data-default-0.4.0 was excluded because data-default-0.3.0 was selected
instead
data-default-0.4.0 was excluded because oryza-0.0.0 requires data-default
==0.3.*
I don't have any idea of what's wrong.
What I did is just inserting one line in Cabal file:
yesod-auth-oauth >= 1.0 && < 1.1
The default scaffolding works fine, which is created through yesod init.
The version information
yesod-core: 1.0.1
cabal-dev: 0.9.1 (build with Cabal 1.14.0)
cabal-install: 0.10.2
GHC: 7.0.4
OS: Mac OS X Lion
Thanks.
This looks like an overly restrictive upper bound in the authenticate-oauth package. It would be best to follow up directly with the maintainer of that package.
In general, these kinds of issues are a side-effect of following the Package Versioning Policy. Basically, it's a trade-off between having these "refuse to compile" annoyances and more insidious "can't compile" problems.
I don't remember for sure, but I think my change to the cabal file for yesod-auth-oauth fixes this.
