Mac OS X 10.5.8 (Intel 32bit), DMD 1.051, LDC Trunk, Tango trunk.

Problem 1: bob hangs after calling ldc or dmd to compile first tango module. Compiler compiles successfully, and bob hangs after it.

(ldc/import:) ./build/bin/osx32/bob -c=ldc -r=ldc -p=osx -vu .
ldc -c -I./tango/core -I./tango/core/rt/compiler/ldc -I. -I./tango/core/vendor -release -oftango-core-Array-release.o ./tango/core/Array.d 
<ldc generates .o, bob hangs here>

Sampling bob from mac system monitor shows this:

Sampling process 31119 for 3 seconds with 1 millisecond of run time between samples
Sampling completed, processing symbols...

Problem 2: bob.sh builds libtango.a fine, but on my mac, linking that lib fails (with dmd or ldc setup): dmd -c test.d and all compilation with dmd or ldc succeeds, but calling ld with linking tango fails with printing missing symbols from libtango.a (lots, maybe all):

(lots of missing symbols from all .o in libtango.a)

What can be the source of problem with linking?

Hi Digited, I think I heard that bob.sh doesn't do the correct thing on OSX, so the problem probably lies there. It is difficult for me to debug though. But maybe you could create ticket(s) for your problem(s)?

On MacOSX, bob.d compiled with ldc works, but bob.d compiled with dmd hangs when executed.
As far as I see, the line that causes the problem is "dup2(pout.sink.fileHandle(), STDOUT_FILENO);" in tango.sys.Process.

Done: #1858 (bob.sh) #1859 (bin/bob)
