Thank you!
Used the wrapper and tried cleaning things up a little (deleted .cabal, .ghc, cabal update). I'm still getting code loading errors - does that seem related?
The surrounding error is at http://lpaste.net/95041.
WHY IS THERE A SUDO.
and this seems to not work if the user used a bin-dist ghc install.
schell: You shouldn't have had to delete .cabal & .ghc -- those aren't affected by the Xcode changes.
The build error you are seeing is a problem with bindings-GLFW - which references the Objective-C run-time symbol __objc_empty_vtable. That symbol changed significantly in 10.9, which causes the error. They seem to know about this issue in the bindings-GLFW repo, and have a fix in head.
it works great, thanks!
mzero: Got it, thanks. I read that ghc 7.7+ (HEAD) will build and link bindings-GLFW fine, so in my quest to build GLFW-b I'm trying to build ghc HEAD. I'm naively using your wrapper to configure the build but am getting a nasty error, I think it might be related to any of the 3(?) issue that are keeping the new haskell platform from releasing. Here's the build output: http://lpaste.net/95206
I installed the wrapper. I have deleted my .cabal and .ghc directories. I first ran cabal update, then cabal install cabal-install. This worked but I don't seem to be able to install other packages:
$ cabal install hashtables
Resolving dependencies...
Configuring hashtables-1.1.2.1...
Failed to install hashtables-1.1.2.1
Last 10 lines of the build log ( /Users/james/.cabal/logs/hashtables-1.1.2.1.log ):
cabal: Error: some packages failed to install:
hashtables-1.1.2.1 failed during the configure step. The exception was:
ExitFailure 10
The log file is empty.
A bit later, having not changed anything I can think of, running 'cabal install hashtables' yields 'Bus error: 10'.
In case feedback is still useful, this script doesn't notice ghc that is installed via stow. (It did patch my existing binary HP one with ghc 7.4.1 though)
I guess I should note that when I upgraded to Mavericks, ghc still seemed to work anyway, but I'm not really following the issue closely enough to know if something broke.
On my system, the builtin echo on line 42 eats up the leading -E. Replacing with /bin/echo fixes that. Yay shell!
Also, clang complains incessantly about the -nodefaultlibs flag, I stripped that out with "${@/-nodefaultlibs/}".
Hi,
I think currently the script does not escape spaces properly. I've stumbled upon this problem when I was trying to build darcs with this wrapper: http://bugs.darcs.net/issue2355?
The
-DPACKAGE_VERSION_STATE="+1 patch"parameter for GHC behaves weirdly and results in build failure as shown in the log: http://pastebin.com/zVK2GkRz@elaforge Could you post a gist with your fix for
-nodefaultlibs?I've fixed the
-nodefaultlibswarning in https://gist.github.com/tibbe/8448715.Works beautifully, thank you!
