I made small improvements in the Small Japi Binding, and asked how to make it available. I received a few private messages advising me to build and package the library using a tool called cabal. Since I have used installation tools for PLT, R and LaTeX libraries, I thought cabal was something similar. However, I noticed that there are a lot of complaints against cabal. Therefore, I decided to install cabal, and try it. It seems that it is easier to install packages by hand than using cabal. Here is a typical cabal session:
D:\ghc\ghcapi>cabal update Downloading the latest package list from hackage.haskell.org
D:\ghc\ghcapi>cabal install mkcabal Resolving dependencies... Downloading pcre-light-0.3.1... Configuring pcre-light-0.3.1... Downloading readline-1.0.1.0... Configuring readline-1.0.1.0... cabal: Error: some packages failed to install: mkcabal-0.4.2 depends on readline-1.0.1.0 which failed to install. pcre-light-0.3.1 failed during the configure step. The exception was: exit: ExitFailure 1 readline-1.0.1.0 failed during the configure step. The exception was: exit: ExitFailure 1
Hmm, I get a slightly different error that indicates somewhat better the actual cause. It says that it cannot find sh.exe. The real problem here is that those two packages use ./configure scripts. Those rarely work under windows. For starters you need msys and mingw installed. Even once you've done that however we get the problem of missing C libs. Duncan
