Description

When I tries to install the vector library on Linux, GHC 7.7 cannot find a necessary primitive library:

% cabal install vector
...
[ 5 of 19] Compiling Data.Vector.Fusion.Stream.Monadic ( Data/Vector/Fusion/Stream/Monadic.hs, dist/build/Data/Vector/Fusion/Stream/Monadic.o )
Loading package ghc-prim ... linking ... done.
Loading package integer-gmp ... linking ... done.
Loading package base ... linking ... done.
Loading package primitive-0.5.0.1 ... <command line>: can't load .so/.DLL for: libHSprimitive-0.5.0.1.so (libHSprimitive-0.5.0.1.so: cannot open shared object file: No such file or directory)
cabal: Error: some packages failed to install:
vector-0.10.0.1 failed during the building phase. The exception was:
ExitFailure 1

Note that static library of primitive is installed but dynamic one is not.

FYI. If I do

% cabal install --enable-shared primitives

, I can install the vector libraries.

After adding mk/build.mk with the following contents, I don't have to install vector by hand.

InstallExtraPackages = YES

Thanks for the report. I've made Cabal build the shared library by default (although note that you'll need to build cabal-install against the HEAD Cabal in order for the 'cabal' program to do so).

    Build shared libraries by default when building for a dynamic ghc; fixes #7846
    
    GHCi will need a shared library, so we build it by default
