Hi Group, i'm trying to complete an haskell pgsql interface. all compiles well when using ghc's generated executable but it segfaults when i do a pqexec. -- PGresult *PQexec(PGconn *conn, const char *query); foreign import ccall "libpq-fe.h PQexec" pqexec::X_PGconn->CString->IO X_PGresult here's the offending code: create conn=do putStrLn "creating table products" putStrLn ("\t"++screate) q<- newCString screate -- segmentation fault here! rs<- pqexec conn q stat<- pqcmdstatus rs stats<-peekCString stat putStrLn ("\tstatus is: "++ show stats) ra<- pqcmdtuples rs ras<-peekCString ra putStrLn ("\trows affected is: "++ show ras) screate= "CREATE TABLE products (" ++ "product_no integer," ++ "name text," ++ "price numeric" ++")" i'm using pgsql 7.4, gcc 3.3.4, ghc 6.2.2 i tried compiling with -fvia-C and it doesn't finish compiling. i'm asking this question in the fear that i have done something wrong. i have posted my code the code, makefile and generated .hc file here: http://www.eyan.org/haskell/ -- kind regards, eyan http://www.eyan.org
