Hi, I’d like to use Haskell for some processing on a MySQL database. Currently, I use Java program to do that but I’d like to change.And an important information, I’m working on OS X Maverick and I use EclipseFP. I installed mysql-simple package. I had some troubles. First, I had to download pcre to get a pcre.h I put into the /usr/include dir. After, to link the mysql-simple package I did an export LD_LIBRARY_PATH=/usr/local/mysql-5.6.11-osx10.7-x86_64/lib. Thus, the library libmysqlclient.18.dylib was found. All stuff above were done by command line. Now, I want to code a simple program: module Main where import Database.MySQL.Simple main::IO() main = undefined hello :: IO Int hello = do conn <- connect defaultConnectInfo [Only i] <- query_ conn "select 2 + 2" return i But when I try to launch a repl from EclipseFP, I’ve got this error: Loading package mysql-0.1.1.7 ... <command line>: can't load .so/.DLL for: /Users/batman/Library/Haskell/ghc-7.8.3-x86_64/lib/mysql-0.1.1.7/libHSmysql-0.1.1.7-ghc7.8.3.dylib (dlopen(/Users/batman/Library/Haskell/ghc-7.8.3-x86_64/lib/mysql-0.1.1.7/libHSmysql-0.1.1.7-ghc7.8.3.dylib, 9): Library not loaded: libmysqlclient.18.dylib Referenced from: /Users/batman/Library/Haskell/ghc-7.8.3-x86_64/lib/mysql-0.1.1.7/libHSmysql-0.1.1.7-ghc7.8.3.dylib Reason: image not found) How can I set the place of this library ? I read some stuff on the web but I don’t understand everything :( Thanks for your help. Chris
