ghci - Compiling Haskell code in Cygwin, and some other bugs in Haskell Platform on Windows -

i trying compile simple hello world programme in haskell, haskell platform 2011.2.0.1. if load code in winghci, , utilize gui compile, .exe created. can run .exe cygwin.

but if seek compile code in cygwin (using ghc --make), linker fails. again, if compile windows cmd prompt, compile+linker works fine.

are there other environment variables need import cygwin, create compile+linker work in it? have set next dirs in cygwin path: 2011.2.0.1/lib/extralibs/bin, 2011.2.0.1/bin (these 2 valid haskell related entries see in windows environment variables).

i noticed couple of invalid items in windows environment variables (this looks bug in haskell installation):

(system var) c/programfiles/haskell/bin - dir not exist because have installed haskell in d disk. (user var) userxxx/applicationdata/cabal/bin - dir not exist.

i tried file bug study in haskellplatform, dont have permission it.

without access development environment or listing of errors you're getting, can assume issue related way you've set path.

ghc on windows comes bundled own gcc compiler (for c code) , ld linker. if you've installed cygwin, you've installed mingw toolchain, comes own version of gcc , ld. then, you've made path variable list /usr/bin before path haskell platform binary directories, makes ghc find mingw linker , c compiler before finds versions bundled ghc.

you need create sure hp directories listed before cygwin directories. should not this:

$ echo $path /bin:/usr/bin:.../2011.2.0.1/bin

instead, should this:

$ echo $path .../2011.2.0.1/bin:/bin:/usr/bin

this guess @ issue might be, , should provide more details improve diagnosis.

How do I check if an insert was successful with MySQLdb in Python? - i have code: cursor = conn.cursor() cursor.execute(("insert new_files (videos_id, filename, " "is_processing) values (%s,%s,1)"), (id, filename)) logging.warn("%d", cursor.rowcount) if (cursor.rowcount == 1): logging.info("inserted values %d, %s", id, filename) else: logging.warn("failed insert values %d, %s", id, filename) cursor.close() fun is, cursor.rowcount always one, though updated database create videos_id unique key. is, insert fails because in tests same videos_id going appear (and when check database, nil inserted). whatever reason, rowcount 1 - logging.warn have spits out rowcount of 1. so, question: can utilize rowcount work out if insert went fine? if so, (presumably) doing wrong? otherwise, how check if insert went fine? your code not commit after modifications (your modifications rolled back). should...
