|#9423||fixed||shutdownCapability sometimes loops indefinitely on OSX after hs_exit()||AndreasVoellmy|
Issue #9284 relates to forkProcess, which previously invoked the same code that is invoked by hs_exit and uncovered this problem. The resolution of #9284 is to not invoke the equivalent of hs_exit (for reasons that you can see in #9284). However, hs_exit can be called by programs that explicitly create and teardown a Haskell runtime, so the problem displayed by #9284 can still occur for those programs.
The problem has only been observed on OS X, though it probably could occur on Linux OSes as well.
|#2083||worksforme||linker reports missing symbols Main.c:(.text+0x12): undefined reference to `__stginit_ZCMain'||Andrew U. Frank|
i use 6.8.2 on linux (ubuntu 7.10). i use mainly eclipse and ghci, but when i try to compile a program, the linker reports the undefined references. for the minimal program 'hello world' i get
Main.c:(.text+0x12): undefined reference to `__stginit_ZCMain' Main.c:(.text+0x2c): undefined reference to `ZCMain_main_closure'
for more interesting programs i get a lot more (i have experimented with wxhaskell and phooey, tv, eros -- and some problems with compiling them in the right order etc..)
suprisingly the problem goes away if the program is called Main.hs - then it links properly, but not when it is called Test.hs. the same program with
main = putStr....
according to the ghc documentation, it is permitted to have in file Test.hs the module main. (and it works properly in ghci)
Documentation for the Error monad. Please take a minute to review it. This is one those parts of the library newbies have difficulties to grok.
Converted the module documentation to Haddock format. Per Jeff Newbern's gracious permission included relevant informationan example from his cool tutorial "All About Monads" http://www.nomaware.com/monads/. Added an example for ErrorT. Use String instead of [Char].
Deadline for the proposal - 2 weeks.
