llvm dev - Apr 2010 - [LLVMdev] Is the option --enable-shared discontinued in 2.7?

When I enabled this option I am getting errors, see below.
Is there any way to fix this? There should be an option to have most of 
the code in shared library.

--enable-shared was _created_ in 2.7. If you were passing it in 2.6 or
earlier, it wasn't doing what you expected.

I just tried it again on trunk (not 2.7) on OSX 10.5, and it works.
What platform are you on? Does it work with another version of gcc?

It's description in online documentation appeared long before 2.7 was 
released, which caused me to believe it that this feature was present in 
2.6. But I never tied to use the shared library anyway.

I am on FreeBSD-8.0 i386. I tried it with gcc-4.3.1 and it also breaks 
the build:

Looks like this is platform dependent. libLLVM-2.7.so created has size 
only 4145 bytes and all llvm symbols are missing.
It's empty because there are no .o modules included into it, only 
libraries through -l options were specified in g++ command line.
Libraries normally are specified with -l option to resolve unknown 
imports, not to be just included into .so library.

All .o files should be listed in the command line instead.
