I am trying to do some research that involves instrumenting LLVM IR,
that I need to test for performance and scalability on a bunch of systems.
I've started trying by trying to get sparc-sun-solaris2.10 (niagara)
working. It appears that neither llvm nor llvm-gcc will build natively
on the system, so I think that I need to build an llvm-gcc cross compiler.
The documentation for building gcc (in general) as a cross compiler
seems to be somewhat dated... and I'm not a very accomplished gnu
hacker. I /think/ that I need to do 5 things.
1) Get the solaris include files. No problem.
2) Build binutils for the target. No Problem.
3) Build a stage1 gcc. Problem.
4) Build a glibc.
5) Build a full gcc.
I configured llvm-gcc with
./../../src/llvm-gcc-svn/configure
--prefix=/Users/luked/opt/sparc
--program-prefix=sparc-llvm-
--enable-languages=c,c++
--build=i686-apple-darwin9
--host=i686-apple-darwin9
--target=sparc-sun-solaris2.10
--disable-nls
--with-gmp=/opt/local
--with-mpfr=/opt/local
--enable-llvm=/Users/luked/install/obj/llvm-svn
--without-headers
--with-newlib
which appears to work fine. While building I get the error at the end of
the email, which I'm fairly sure is related to something that I am doing
wrong, but I'm not sure what it is.
I've been following the instructions in
https://www6.software.ibm.com/developerworks/education/l-cross/l-cross-ltr.pdf
Any advice would be great.

These two are wrong. You don't want to use newlib. You want to use headers from solaris, as otherwise, you'll get:> ../../../../src/llvm-gcc-svn/gcc/tsystem.h:90:19: error: stdio.h: No > such file or directory:-)

I'm not exactly following this. I have gcc installed on all of the systems that I work with.>> The documentation for building gcc (in general) as a cross compiler >> seems to be somewhat dated... > > The scheme has not changed (much) in the past 15 years.Good.>> 4) Build a glibc. > > No, I'd nix this part.OK, I didn't understand the dependency on glibc. I was just following that IBM document.> >> --without-headers > > ? > >> --with-newlib > > ? > > These two are wrong. You don't want to use newlib. You want to use > headers from solaris, as otherwise, you'll get: > >> ../../../../src/llvm-gcc-svn/gcc/tsystem.h:90:19: error: stdio.h: No >> such file or directory > > :-)OK. So I've discovered --with-sysroot which seems to be grabbing and patching the include files correctly. Now it's dieing with ./options.h:462: error: 'HOST_BITS_PER_INT' undeclared here (not in a function) ./options.h:462: error: bit-field 'padding' width not an integer constant which appears to be llvm-gcc specific because it doesn't happen in vanilla 4.2.4. I'm definitely moving forward though. Thanks for the advice.
