Just to avoid doubt, I want to be absolutely clear what you're

Kahuna, any news? Did you manage to get your build working?
Sorry I was without internet during the weekend (THE HELL ON
EARTH!!! :-), I'm using gcc 4.8.1 binary distribution for osx to
compile gcc-4.8.2, I also tried gcc-4.7.0 to compile latest
gcc-4.7.3 with identical result (the gcc-4.8.1 was downloaded
from
http://sourceforge.net/projects/gnuada/files/GNAT_GCC%20Mac%20OS%20X/4.8.1/)
and gcc-4.7.0 from the equivalent place for it.
the problem seems to be related to double underscore and simple
underscore during the linking process. Compiling an empty main()
and then linking produce lot of errors similar to
Undefined symbols for architecture x86_64:
"_D10TypeInfo_a6__initZ", referenced from:
….
if I make
nm libgphobos.a | grep D10TypeInfo_a6__initZ
I get:
U _D10TypeInfo_a6__initZ
U _D10TypeInfo_a6__initZ
U _D10TypeInfo_a6__initZ
U _D10TypeInfo_a6__initZ
00000000000002b0 S __D10TypeInfo_a6__initZ
U _D10TypeInfo_a6__initZ
so maybe the compiler is failing when building the libgphobos.a
With gcc-4.8.2 I get the equivalent for libgphobos2.a
maybe the linker for OSX is not compatible with something deep
inside gdc?? I have compiled c++ and c code without problems
using those compilers and the references for c++ classes are
correctly constructed with double underscore prefix..
Any idea?
