I tried building ldc2 but failed. I installed llvm 2.8 but ldc2 fails at 
building the file gen/arrays.cpp:
build/ldc2/gen/arrays.cpp:445: error: ‘struct Type’ has no member named 
‘mutableOf’

BTW it gives me many warnings when building. How did you build ldc2? I'll guess 
I have a incompatible version. Could check http://www.dsource.org/projects/ldc 
because it's down.

Debian comes with a packaged ldc.
$ ldc --version
LLVM D Compiler rev. 
based on DMD v1.056 and llvm 2.6 (Fri Feb 26 11:01:51 2010)
...

I made it almost work. I could not find the compiler switch to build a static 
library. What's ldc's equivalent for dmd's -lib?

I think I found the answer to my last question. To build static libraries one 
has to use ar. I try to add this.

I can build using ldc1. But we have sample apps in our test suite that require 
phobos. So I'd like to try ldc2 to make sure that works. Can you provide me 
some information on building ldc2?

Thanks. We are looking forward to support ldc2.
How did you compile it? I'll guess there is some combination of llvm and ldc2 
that will compile.

Sorry. I'm having problems understanding that. Which version of llvm and ldc 
should I use? I did hg clone http://bitbucket.org/prokhin_alexey/ldc2 (tip is 
at 1711:2db59994970e) for ldc and used this llvm 
http://llvm.org/releases/2.8/llvm-2.8.tgz.

My tip is now at 1728:119b166d3fdb. gen/configfile.cpp.o failed with 
gen/configfile.cpp:8:25: error: libconfig.h++: No such file or directory.
I installed libconfig++ and compiling works. Maybe you can add a check for 
libconfig++.

We have a little test program.
testCompiler.d:
int main(char[][] args)
{return args.sizeof-1;}

When I do
$ ldc -offoo -c testDCompiler.d

I get:
Error: failed to auto-select target: No available targets are compatible with 
this triple, see -version for the available targets., please use the -march 
option

Then I did:
$ ldc -march=i486 -offoo -c testDCompiler.d

getting:
Error: you must specify a target triple as well with -mtriple when using the 
-march option

How do I build the testCompiler.d?

Try to rebuild LDC:
$ cd path_to_ldc_build_dir
$ cmake -DDEFAULT_TARGET=i686-pc-linux-gnu 
-DDEFAULT_ALT_TARGET=x86_64-pc-linux-gnu .
$ make

Thank you.
$ ldc -offoo -c testDCompiler.d
object.d: Error: module object is in file 'object.d' which cannot be read
import path[0] = /usr/include/d
import path[1] = /usr/include/d/ldc

I tried adding the path from my dmd installation to ldc.conf. Had no effect. 
Where do I need to add the import path?
Adding it manually
$ ldc -I/home/jkm/local/x86_64-linux-gnu/src/druntime/import -offoo -c 
testDCompiler.d

results in
/home/jkm/local/x86_64-linux-gnu/src/druntime/import/object.di(21): found 
'char' when expecting ')'
/home/jkm/local/x86_64-linux-gnu/src/druntime/import/object.di(21): no 
identifier for declarator immutable
/home/jkm/local/x86_64-linux-gnu/src/druntime/import/object.di(21): semicolon 
expected to close alias declaration
/home/jkm/local/x86_64-linux-gnu/src/druntime/import/object.di(21): Declaration 
expected, not ')'

cmake . -DD_VERSION:STRING=2 -DRUNTIME_DIR:PATH=/usr/include/d/tango 
-DPROGRAM_PREFIX:STRING=2

or

cmake . -DD_VERSION:STRING=2 -DRUNTIME_DIR:PATH=/usr/include/d/dmd/phobos 
-DPROGRAM_PREFIX:STRING=2

i add number 2 at ldc because i use too ldc (d1)

Thanks. But not done yet.
$ ldc2 -offoo testDCompiler.d
/usr/bin/ld: cannot find -ldruntime-ldc
collect2: ld returned 1 exit status
Error: linking failed:

I have no libdruntime-ldc.so or .a. 

$ make runtime
fails with
../src/druntime/src/core/runtime.d(385): Error: class 
core.runtime.defaultTraceHandler.DefaultTraceInfo interface function

make[2]: *** [runtime/CMakeFiles/druntime-ldc.dir/all] Error 2
make[1]: *** [runtime/CMakeFiles/runtime.dir/rule] Error 2

Which version of dmd are you using. I have v2.050.
