For those interested, the patch for parsing the paths that contain spaces
(windows installs of mysql), I passed along the changes for Setup.lhs so that
the split skips spaces inside quotes:
mysqlBuildInfo :: LocalBuildInfo -> IO BuildInfo
mysqlBuildInfo lbi = do
let mysqlConfig = rawSystemProgramStdoutConf verbosity mysqlConfigProgram
(withPrograms lbi)
includeDirs <- return . map (dropWhile (\x -> elem x "-I") ) . split =<<
mysqlConfig ["--include"]
ldOptions <- return . split =<< mysqlConfig ["--libs"]
return emptyBuildInfo {
ldOptions = ldOptions,
includeDirs = includeDirs
}
where
verbosity = normal -- honestly, this is a hack
split :: [Char] -> [[Char]]
split xs@(l:lx) = if (elem '\"' xs)
then let x = dropWhile (== '"') xs
y = takeWhile (/= '"') x
in y : split ( dropWhile (\n -> elem n "\" \r\n\t") (drop
(length y) x))
else let x = takeWhile (\n -> not (elem n " \r\n\t") ) xs
in x : split ( dropWhile (\n -> elem n " \r\n\t") (drop
(length x) xs))
split [] = []
This hasn't fixed everything, such that I have a complete install of HDBC-mysql
on Windows, but it is a step.

Roderick, thanks for passing this along. To be honest, I haven't tried to
build this on Windows yet. I have an old PC that I keep meaning to get things
going on. If you're able to get things working, I'd be more than happy to
integrate any changes that you want to send along... patches are very much
appreciated! :)
thanks!

Hello,
In order to build (cabal install HDBC-mysql) the HDBC-mysql package, I am
having to make the following changes:
(1) I had to change the mysql (5.1.45 community distrib msi) to use a wrapper
exe on the mysql_config.pl and put this in c:\program files\mysql\bin since
although the c:\program files\mysql\scripts\, where mysql_config.pl resides,
was in the path, even the commandline call to it was not finding or using
it...very strange. This of course doesn't directly have to do with the
HDBC-mysql package.
--The quick wrapper was:
import System.Environment(getArgs)
import System.Process(readProcessWithExitCode)
import System.Exit(exitWith,ExitCode(ExitSuccess))
main = do
args <- getArgs
(ecode,out,err) <- readProcessWithExitCode "c:\\Perl64\\bin\\perl.exe"
("C:\\Program Files\\MySQL\\scripts\\mysql_config.pl" : args) ""
if ecode == ExitSuccess
then mapM_ putStrLn (lines out)
else mapM_ putStrLn (lines err)
exitWith ecode
-- so now the output is:
"C:\Program Files\MySQL\lib\mysqlclient.lib" "wsock32.lib" "advapi32.lib" "user3
2.lib"
(2) Once that was done, the "cabal install HDBC-mysql" call was able to find
the mysql_config. However, it was splitting the values returned by mysql_config
on space, and thus failed to find mysql.h, as the resulting command was:
C:\Program Files (x86)\Haskell Platform\2009.2.0.2\gcc.exe -c -BC:\
Program Files (x86)\Haskell Platform\2009.2.0.2\gcc-lib -IC:\Program Files (x86)
\Haskell Platform\2009.2.0.2\include\mingw -D__GLASGOW_HASKELL__=610
-IIC:\Program -Iles\MySQL\include\mysql" ...
-- then I tried taking the -I out of the mysql_config.pl script and got the
following from the "cabal install HDBC-mysql"
command was: C:\Program Files (x86)\Haskell Platform\2009.2.0.2\gcc.exe -c -BC:\
Program Files (x86)\Haskell Platform\2009.2.0.2\gcc-lib -IC:\Program Files (x86)
\Haskell Platform\2009.2.0.2\include\mingw -D__GLASGOW_HASKELL__=610
-I:\Program -Iles\MySQL\include\mysql" ... blah blah blah
cabal: Error: some packages failed to install:
HDBC-mysql-0.6.1 failed during the building phase. The exception was:
exit: ExitFailure 1
... so finally I am downloading your package to see if I can figure out a fix
for windows boxes. Just thought I would give you a heads up on this
windows-related bug.
Thanks,
Roderick
