Of course I will share my binaries if necessary. Absolutely. They are 32
bits, thought.

My compilation notes are these, in SPANISH. I don't think they are
useful to you:

"""
* LLVM 2.7 (09/jun/10)

URL: http://llvm.org/

Estado: En produccion en Stargate-Host

Intento compilar con

  ./configure --enable-shared --disable-static

pero no funciona, asi que configuro "./configure" a secas.

Para instalar, tengo que añadir "SHELL=/bin/bash" a "docs/Makefile".

Se puede probar con "make check". No vale la pena bajarse la testsuite
completa.

Hay que compilar tambien su "clang" correspondiente. Para ello hay que
copiarlo dentro y compilarlo todo de una vez.


[...]

* CLANG 2.7 (09/jun/10)

URL: http://clang.llvm.org/

Estado: En produccion en Stargate-Host.

Compilador de C basado en LLVM.

Hay que compilarlo al mismo tiempo que su LLVM correspondiente. Es
decir, "clang" es una extension que hay que meter dentro del LLVM y
compilarlo todo junto.

Una vez compilado, hay que meterse en su directorio y hacer "make test",
"make install".

"""

Maybe the useful bit is that "clang" must be copied inside LLVM and the
entire package be compiled at once.


My build environment is very customized, with years of refinement. My GCC:

"""
[root at babylon5 /]# gcc -v
Using built-in specs.
COLLECT_GCC=gcc
COLLECT_LTO_WRAPPER=/usr/local/libexec/gcc/i386-pc-solaris2.10/4.5.0/lto-wrapper
Target: i386-pc-solaris2.10
Configured with: ../gcc-4.5.0/configure --with-gnu-as
- --with-ld=/usr/ccs/bin/ld --without-gnu-ld --enable-shared
- --enable-languages=c,c++,fortran,objc,obj-c++
Thread model: posix
gcc version 4.5.0 (GCC)
"""

Note that I use GCC but the linker is Solaris 10 one, not GNU. Note also
that I compile 32 bits usually.

I am very impressed with CLANG. I would support Illumos to be able to be
compiled with it.

PS: All this is under Solaris 10. I am not an OpenSolaris user at this
moment.
