I am trying to install dph-examples in mac os x version 10.7.2 and I got this error. How ever on ghci , I can see
ghci>import Data.Array.Parallel.
Data.Array.Parallel.Base Data.Array.Parallel.Base.DTrace Data.Array.Parallel.Base.TracePrim Data.Array.Parallel.Stream
but not Data.Array.Parallel , Data.Array.Parallel.Prelude and Data.Array.Parallel.Prelude.Double. I copied the example ( it uses these libraries ) given on Data-Parallel-Haskell and its working fine. My program is compiling and running so my question is, why i am not able to see these library at ghci prompt. Also i am not able to find the reference for sumP function at the Data-Array-Parallel. I am using ghc-7.2.1.
GHC depends on Xcode 3.2:
The package requires Xcode 3.2 (in particular, the "Unix Development Support") to be already installed.
— GHC 7.2.1 download page
Xcode 3.2 should already come with LLVM, so if it's not already installed, installing it should fix things. If you already have it installed, then your installation might be broken somehow; you could try reinstalling it to make sure. I think Xcode 4 isn't fully supported by GHC yet, so if you have it installed, that might be the problem; you could try uninstalling it and installing 3.2 instead.
Warning: Couldn't figure out LLVM version!
Make sure you have installed LLVM
Perhaps you didn't install LLVM? Go install LLVM.

I use Xcode 7.2 on OS X 10.11.
However, I must build using older Xcode SDK (10.8) to support older platform.
I have a problem when I link to libpng installed using homebrew.
A bunch of warnings like following pop up:
Object file
(/usr/local/Cellar/libpng/1.6.21/lib/libpng.16.a(pngwutil.o)) was
built for newer OSX version (10.11) than being linked (10.8)
The problem would be obviously solved if I could force homebrew to compile recipe using older Xcode SDK (10.8) but haven't find a way to accomplish this.
Any suggestion is welcome.
I just updated to OS X Mavericks and it seems it messed up my whole compiler setup. Not only do I have to reinstall a JDK in order to use a Java compiler, I get the following error when I'm trying to compile C/C++ using GCC/G++:
/usr/local/Cellar/gcc/4.7.2/gcc/lib/gcc/x86_64-apple-darwin12.2.1/4.7.2/../../../../include/c++/4.7.2/cwchar:46:19: fatal error: wchar.h: No such file or directory
Not sure what to think other than upgrading messed it up. My question is: how do I set up g++ to compile on OS X? If it's already set up, what is the problem here?
If I can provide more information, please let me know.
Note: I've installed gcc 4.7 using homebrew, but it doesn't seem to work. When I use g++-4.7 code.cpp specifically, I get the same error.
Installing the Command Line Tools (OS X Mavericks) for Xcode - Late October 2013 solved it for me. Here is the link:
OSX: Xcode Downloads
The often mentioned xcode-select --install command kept saying it cannot find the requested software.
To clarify: You need to already have gcc-4.7 installed using Homebrew. The update to the latest version of CMD Tools only fixes compatibility issues caused by upgrading from Mountain Lion to Mavericks.
The ironic thing is that all this used to work on my Mac, but Apple no longer supports 10.5.8, so I was forced to update to Snow Leopard, 10.6. And everything broke (thank you Apple).
On the surface, it seems simple. Build an open source package like octave under Snow Leopard (Mac OS X 10.6)
Apple has made this difficult, to say the least. They no longer download XCode for older operating systems unless you are a paid developer. My Macbook pro 2.16Ghz cannot load Lion, so that option is not available.
My old fink doesn't work because it was old. In order to build a new one, I need Xcode 3.2, which I can't get (see above).
I downloaded a free gcc 4.2, and it works fine.
So in order to try to build octave, it's the old style gnu install:
./configure
make
make install
./configure fails because there is no fortran installed. That's a special case because the install of gcc didn't include fortran. So a fallback would be building a complete gcc which I have done in the past.
downloaded gcc 4.9:
gcc-4.9-20130728
inside, gcc49
gcc can't build because it needs the three subsidiary packages gmp, mpfr and mpc
I am now trying to build these, so that I can bootstrap a complete gcc build, but in the meantime, is there any simpler way to bootstrap these things? I find it hard to understand why no binaries are available for:
fink
octave
which would solve part of my current problems.
You can still get XCode. You just have to be registered on Apple Developer, but you do not have to pay for the license. You then download it through the Mac App store, or you can get a link that opens it in the App store here. Finally, you have to install the command line tools from within Xcode. These can be found under the Components tab of the Download Preferences panel.
Let me know if that does not help. My iMac running 10.6 is currently in for repairs, so I am on my 10.7 laptop and cannot test all the specifics yet.
Until recently I used to have Xcode 4.2 with the osx-gcc-installer installed on top of it, which worked quite well for older versions of Ruby.
The thing is, that now that I installed Xcode 4.3 with the command line tools (for homebrew), I found that I don't have gcc-4.2 on my system.
From what I was able to find, the usual way to install pre 1.9.3 is to either get an older version of Xcode, or using the osx-gcc-installer. I also found a warning saying that if I install osx-gcc-installer over Xcode 4.3, it will cause problems with node.js.
As I'm currently doing both iOS and node.js development alongside Ruby, I can't really do any of these things. Which means I can only work with 1.9.3, which is the only Ruby version that can be compiled with LLVM.
Is there a clean way to install any older version of Ruby without sacrificing Xcode 4.3? The solution that comes to my mind is having gcc-4.2 in some kind of non-system-wide sandbox and specify it's path when installing Ruby, but I'm not really sure how to do this properly.
Update:
See this link for the process required to get GCC-4.2 onto a machine with Xcode 4.3 without overwriting other components.
Xcode 4.3, Homebrew, and Ruby
It will obviate the need for the instructions below:
RVM should work if you set the default compiler for RVM to gcc. Place this in your .bashrc or .zshrc.
export CC=/usr/bin/gcc-4.2
RVM should then use GCC to compile.
If you don't want to have CC set permanently then you could try installing with:
CC=/usr/bin/gcc-4.2 rvm install 1.8.7
I have installed the developer tools. I can compile code via Xcode and according to the docs /usr/bin/gcc & /usr/bin/cc should point to /usr/bin/gcc-4.0. Neither the symlinks or gcc-4.0 exist on my system (Snow Leopard). All I wish to do is compile some C on the terminal! I'm amazed by how complicated this task is. The command GCC is unsurprisingly returning "gcc: command not found".
Can anyone shed some light on this?
No! Reinstalling is the wrong answer!
Newer versions of XCode require you to install the command-line versions of the tools separately. In XCode, go to Preferences | Downloads, check the Components tab, and install them from there:
These binaries should be there after installing xcode. Check your path settings, and if you still don't have these reinstall xcode
Command line tools are no longer included with the latest XCode (even as an add on). Now you can download them here:
https://developer.apple.com/downloads/index.action
Did you install the latest Xcode after installing Snow Leopard, or is this the version of Xcode from a previous OS installation?
On my system with a clean Snow Leopard install the default compiler (and the one symlinked from cc and gcc) is gcc-4.2
I do have gcc-4.0 too, although it's not the default.
