I tried to start using D with ldc and got a link error on osx 64 bit

1. Hello, I'm finally starting to code with D and as I wish to target sooner or later ARM platform I want to use llvm directly. So I compiled it yesterday on OSX Snow Leopard 64bit and got this problem while trying to compile the helloworld :
   
   
   test.d hello world :

   import std.stdio;
    
   void main()
   {
     writeln("Hello World!");
   }

   
   
   ldc2 test.d
2. Undefined symbols for architecture x86_64:
3.   "__tlv_bootstrap", referenced from:

13. collect2: ld returned 1 exit status
14. Error: /usr/bin/gcc failed with status: 1
    
    
    I guess that I have a link problem with phobos, but as phobos was compiled during the build of ldc, I would expect it to work. Do I have to add additionnal arguments for linking my program with phobos ? So basically here, my question would be what should I do for correcting this problem ?

Hi,

I cannot reproduce the problem on my OS X box, everything works
smoothly after running »make install«. I'm running OS X 10.7.5 with
Xcode 4.4.1, with LDC built against LLVM 3.1 compiled from sources
(using ./configure). "gcc" is "i686-apple-darwin11-llvm-gcc-4.2". What
is your environment?

The strange thing is that as far as I know, _tlv_bootstrap is just a
»marker« symbol picked up by the toolchain for programs which use TLS.
There should be no need to link to anything manually to get its
definition.

On a general note, GDC seems to be a bit further than LDC right now
w.r.t. ARM support. I definitely plan to look into it in the near
future, but getting a solid x86/x86_64 release out is the top priority
right now.

David
