I try to build qhull from hackage and get the error
fatal error: qhull_ra.h: No such file or directory
2 | #include "qhull_ra.h"
`gcc' failed in phase `C Compiler'. (Exit code: 1)
The file is in the Cdir and the relevant parts of the cabal file are
include-dirs: ./Cdir
C-sources: ./Cdir/libqhull_r.c
, ./Cdir/geom_r.c
, ...
The file qhull_ra.h is not listed as C-sources, because it is a header file.
I did not write the code and are not experienced with including C code into haskell packages. The failure occurs sometimes and sometimes not, but I cannot tell when. What is wrong? I want to upload the package (authorized by the author); what do I have to change to make it compile with cabal install?
I've noticed that cabal install is (since recently) much more strict than cabal build when looking for files. So, I believe here the problem is that your include files are not being picked up by cabal.
I think you can fix that by listing your header files in a includes: field. So at least:
include-dirs: Cdir
includes: qhull_ra.h
c-sources: Cdir/libqhull_r.c

someone could help me?! I'm working in a Haskell Yesod site for college on a C9 workspace, I've already installed by command Yesod and update cabal, but when I try "stack build" command, this miserable error message appears:

Seriously, I tried a bunch of things to fix it, but nothing is working =S
Just read the error message carefully:

Perhaps you need to add ‘http-types’ to the build-depends in your .cabal file.
Use -v to see a list of the files searched for.
The line Perhaps you need to add ‘http-types’ to the build-depends in your .cabal file tells you what to do: You must add http-types to the build-depends: section of the library aulahaskell in your cabal file.
If this does not help, please post your cabal file.
How did you start the yesod project? It's recommended to do:
stack new my-yesod-project yesod-(your database here)
cd my-yesod-project
stack build
Thank you, guys! It was a problem on how I was starting the project, some files weren't installed on my workspace, so I delete the files, reinstall Yesod and cabal, create another new version after following this steps: https://www.yesodweb.com/page/quickstart
I'm new to Haskell but I want to try and write some OpenGL experiments in it.
I've successfully installed OpenGL, GLUT and a few other packages but when I attempt to install GLUtil I get the following error:
Building GLUtil-0.9.0.1...

ExitFailure 1
I tried using older versions of GLUtil and its dependencies but it always ended the same way and I eventually just cleared and reinstalled the Haskell Platform (I didn't know about sandboxing).
One thing that stands out is that -includeC:\Users\Dav... looks to me like a typo, as if there should be a space between -include and C:\... but I don't know how to change this. I couldn't find CmdLine.hs, just the interface file CmdLine.hi which yielded no results.
Does anyone have any advice on how to remedy this?
It appears that there should be a space between the -include and the file name.
I created a version of GLUtil-0.9.0.1 that is already preprocessed and should work for you:
https://github.com/erantapaa/GLUtil-0.9.0.1-no-cpp
It assumes you are using GHC 7.10.x or later.
The steps to remove the dependency on CPP were:
files JuicyTextures.hs and ShaderProgram.hs just use CPP to include Control.Applicative for older versions of GHC, so I just commented out those lines. Also remove CPP from the LANGUAGE pragma.
Linear.hs uses CPP to generate code. You can create the pre-processed output with:
gcc -E - < Linear.hs > new-Linear.hs
Then remove lines beginning with a hash (#) and remove CPP from the LANGUAGE pragma.
in GLUtil.cabal comment out/remove the lines:
if impl(ghc >= 7.10.1)
Build-depends: hpp >= 0.3 && < 0.4
GHC-Options: -pgmPhpp -optP--cpp -optP-P
else
Build-tools: cpphs
GHC-Options: -pgmPcpphs -optP--cpp -optP
I'm using Ubuntu 14.10 with GHC 7.6.3 and cabal installed via the Ubuntu package installer, and trying to use the Heap data structure, which I naively installed using:
cabal install heap
As soon as I started importing the library into my code, I got the following linking error:
...
Loading package primitive-0.5.0.1 ... linking ... done.
...
Loading package heap-1.0.0 ... linking ... done.
...
Loading package primitive-0.5.2.1 ... linking ... done
...
GHCi runtime linker: fatal error: I found a duplicate definition for symbol
hsprimitive_memset_Word32
whilst processing object file
/home/simon/.cabal/lib/primitive-0.5.2.1/ghc-7.6.3/HSprimitive-0.5.2.1.o
This could be caused by:
* Loading two different object files which export the same symbol
* Specifying the same object file twice on the GHCi command line
* An incorrect `package.conf' entry, causing some object to be
loaded twice.
GHCi cannot safely continue in this situation. Exiting now. Sorry.
This answer notionally explains what to do, but the instructions are not specific enough for me to follow.
How do I get Heap to use primitive-0.5.2.1 (I'm assuming that this lightly used library is the one that is out of date), or should I be doing something completely different?
One solution might be to specifically install an earlier version of heap:
cabal install heap-0.6.0
You might have to first unregister heap-1.0.0.
Another option is to blow away your ~/.ghc directory. Of course, you will have to reinstall cabal packages.
I think the best option is to start using cabal sandboxing for your projects.
Edit: heap-1.0.0 contains QuickCheck tests and thus brings in all of the QuickCheck dependencies. To install that version without QuickCheck, try this:
In a new directory, run cabal get heap-1.0.0
cd heap-1.0.0
Edit heap.cabal and remove the Build-Depends: line
Run cabal install
I'm trying to compile haskell ghc from source. I try to configure my cabal config from different folder than /usr/. From the start it always succeed in building any package.
At some point (after installing package cabal-install), I change my config for cabal to include another "library-dirs". Then, something wrong happens (probably because wrong string to be inserted in field "library-dirs" in cabal config). So, I try to reconfigure my cabal config file again (I even delete the config file and try to clean the ghc package cache) and comment field "library-dirs" options but it still fails. I also already tried to remove the cabal package directory (a directory where cabal save the cache about the packages).
This is the output when using "ghc-pkg check" :
Warning: library-dirs: {stripped} doesn't exist or isn't a directory
This is the output right now when I building package using cabal or manually from Setup.hs :
sudo -E cabal --config-file=/opt/haskell/config/config install hashable -O2 --global --flags="-fllvm" --prefix=/opt/haskell 2>error --upgrade-dependencies --reinstall

Can anybody help me or guide me ? Or at least tell me where ghc are actually save the information of "library-dirs" configuration for an uninstalled package ?

Thank you.
I believe this might be due to the fact that each package contains the full path to the location when it was first created. Look into. .ghc/YOUR_PLATFORM/package.conf.d(for me, it's .ghc/x86_64-darwin-7.6.3/package.conf.d). You'll see a lot of .conf files, and each will contain hardcoded paths:
[...]
import-dirs: /Users/pejvan/Library/Haskell/ghc-7.6.3/lib/pandoc-types-1.12.3.3/lib
library-dirs: /Users/pejvan/Library/Haskell/ghc-7.6.3/lib/pandoc-types-1.12.3.3/lib
[...]
haddock-interfaces: /Users/pejvan/Library/Haskell/ghc-7.6.3/lib/pandoc-types-1.12.3.3/doc/html/pandoc-types.haddock
haddock-html: /Users/pejvan/Library/Haskell/ghc-7.6.3/lib/pandoc-types-1.12.3.3/doc/html
You can either manually update the files for the contents to point to the right location or write a script which would do it for you.
Then you need to update the package.cache files (might require a sudo here and there):
pejvan$ ghc-pkg recache
pejvan$ ghc-pkg recache --user
Finally, check that everything is now fine:
pejvan$ ghc-pkg check
This is the output from cabal install codec-image-devil:
Resolving dependencies...
Configuring Codec-Image-DevIL-0.2.3...
cabal: Missing dependency on a foreign library:
* Missing C library: IL
This problem can usually be solved by installing the system package that
provides this library (you may need the "-dev" version). If the library is
already installed but in a non-standard location then you can use the flags
--extra-include-dirs= and --extra-lib-dirs= to specify where it is.
cabal: Error: some packages failed to install:
Codec-Image-DevIL-0.2.3 failed during the configure step. The exception was:
ExitFailure 1
I tried --extra-include-dirs and --extra-lib-dirs. but they didn't work. so I edited the .cabal in Codec-Image-DevIL-0.2.3.tar.gz. I don't know if I'm even supposed to change that. but it worked for pthread.
I added these two lines:
include-dirs: C:\Users\Rumbold\Documents\libs\IL\include, C:\Users\Rumbold\Documents\libs\pthread\include, .
extra-lib-dirs: C:\Users\Rumbold\Documents\libs\IL\lib, C:\Users\Rumbold\Documents\libs\pthread\lib, .
They are indented so they are in the Library section. I don't know if I got the format for lists right, just something i stumbled upon while googling. The libs and `header files are all in the correct place, I think.
any clue how i can get it to work?
Edit_1:
I got it to work with --extra-include-dirs and --extra-lib-dirs, so I don't need to edit the cabal anymore. but IL still doesn't work. is there a way to find out which files it's looking for?
Wdit_2:
Alright it works. I had to rename DevIL.lib and DevIL.dll to libIL.lib and libIL.dll. (not sure if I had to do both, but that's what I did. also kept them under their old names)
Edit_3:
Getting lots of errors like:
"cabal\Codec-Image-DevIL-0.2.3\ghc-6.12.3/libHSCodec-Image-DevIL-0.2.3.a(DevIL.o):fake:(.text+0x2379):
