I'm working on a Linux machine with GHC 7.8.2 and cabal 1.20.0.1.
I'm trying to install semigroups and whenever I do, I get the dreaded error message about missing dyn_hi files.
/home/me/.cabal/lib/x86_64-linux-ghc-7.8.2/semigroups-0.14
setup-Simple-Cabal-1.18.1.3-x86_64-linux-ghc-7.8.2: Error: Could not find
module: Data.Semigroup with any suffix: ["dyn_hi"] in the search path:
["dist/build"]
cabal: Error: some packages failed to install:
semigroups-0.14 failed during the final install step. The exception was:
I've tried following the advice given here and here. I've removed .cabal/config, .ghc, added shared : True and followed each step.But after multiple repetitions of these instructions I'm still getting the same errors.
Is there any other way to diagnose and fix these errors?

I've had nothing but trouble using cabal, not sure if it's due to a lack of understanding, or a faulty mental model, but things have been tough.
At the moment I'm just trying to get ghc-mod to work for my vim plugins. It usually works for a day or two and then starts failing for seemingly no reason with an error, the error I receive seems to change from time to time, right now I'm getting this one:
$ ghc-mod check Main.hs
ghc-mod: /Users/chris/.stack/snapshots/x86_64-osx/lts-6.15/7.10.3/pkgdb/package.cache:
GHC.PackageDb.readPackageDb: inappropriate type (Not a valid Unicode code point!)
Any ideas about how to fix this sort of thing? I've tried installing it again, but I get this (I think my cabal packages are all screwed up but don't know how to fix it):
$ cabal install ghc-mod

Edit:
Looked away for a second and tried again, now I'm getting this error, getting kinda sick of cabal changing its mind all the time:

This error was caused by having a mismatch between my local stack ghc version and the global ghc-mod ghc version, I updated the ghc version in the stack project to latest and everything is working fine.
I followed "Yesod quick start guide" to install Yesod in Windows 10.
But, when I issued the stack build command, it failed.
Environment
Windows 10 (64bits)
stack-0.1.5 (for Windows10 64bits)

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.

It seems that the cause of the error were the duplicated GHC installation.
Thanks for #Reid comment, I realized that I installed Haskel Platform from exe file before and I also installed GHC through stack by folloing the guide.
I unisatlled GHC of Haskel Platform and executed 'stack setup' command.
Then, I executed 'stack build' command and it seemed worked.
I still have problems with the 'stack build' command, but I solved this issue.
I'm trying to cabal install binary-strict and I get this error:

It could refer to either `Foreign.unsafePerformIO',

Failed to install binary-strict-0.4.8.1
cabal: Error: some packages failed to install:

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 trying to install the regex-dfa package. I installed other regex packages like regex-tdfa, and they worked fine.
However, when I run sudo cabal install regex-dfa I get an error message:

cabal: Error: some packages failed to install:

What can I do about this?
The package is very old, the last (and the only) upload was in 2007. Don't use it if you can. Or contact the maintainer and ask him to update the package.
To fix this particular issue, you can cabal unpack regex-dfa, remove the -Werror and then cabal install it. But I'm not sure you will get another build error after that.
I am on a linux box and trying to experiment with Haskell's Accelerate library but having problems installing it. I have successfully installed the accelerate package but there seems to be a dependency problem, which I have detailed below.
cabal: Error: some packages failed to install:
accelerate-cuda-0.14.0.0 depends on haskell-src-exts-1.14.0.1 which failed to
install.
cuda-0.5.1.1 failed during the configure step. The exception was:
ExitFailure 1
haskell-src-exts-1.14.0.1 failed during the configure step. The exception was:
ExitFailure 1
haskell-src-meta-0.6.0.5 depends on haskell-src-exts-1.14.0.1 which failed to
install.
language-c-quote-0.7.6 depends on haskell-src-exts-1.14.0.1 which failed to
install.
I searched SO and noticed someone else had a similiar issue installed the cuda package, and was resolved by adding the cabal bin path to the PATH; I tried this but it didn't solve this problem.
Please could someone help as I really keen to play with this fantastic library.
I wanted to check accelerate-examples and play with them and I also didn't have CUDA GPU (AMD only) and that's how I eventually installed accelerate-examples with stack:
git clone https://github.com/AccelerateHS/accelerate-examples
cd accelerate-examples
#choose version:
ln stack-8.6.yaml stack.yaml
#build without CUDA targeting:
stack build --flag accelerate-examples:-llvm-ptx --flag accelerate-fft:-llvm-ptx
Installation will build all the examples and print the info regarding where they was put.
Might also need to specify GHC libs path with something like: export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:~/.stack/programs/x86_64-linux/ghc-8.6.5/lib/ghc-8.6.5/rts/
Also checked that accelerate installs as well the same way but even without specifying any flags (I guess because it doesn't build any programs yet?), but examples are what's fun :)
P.S. You can move llvm-ptx flags to stack.yaml config: change # flags: {} line to:
flags:
accelerate-fft:
llvm-ptx: false
accelerate-examples:
llvm-ptx: false
