Hi Andre,
I'm trying to build LLVM-gcc to compile Ada.
excellent!
But I'm having a few problems.
Oops 
Now when I ran make I get an error that for me it seams very weird.

Looks like you forgot to specify --enable-llvm when configuring
llvm-gcc.
Ciao,
Duncan.

Hello Duncan,
I put enable-llvm this time, but got another error.
In file included from ../../gcc/llvm-backend.cpp:23:
../../gcc/llvm-internal.h:31: fatal error: vector: No such file or directory
compilation terminated.
make[2]: *** [llvm-backend.o] Error 1
make[2]: Leaving directory `/home/andrelct/apps/llvm-gcc/build/gcc'

make[1]: Leaving directory `/home/andrelct/apps/llvm-gcc/build'

Do you have an idea of what it is?
My new config is
../configure --enable-languages=c,c++,fortran,ada --disable-bootstrap
--disable-nls --disable-multilib --enable-checking
--program-prefix=llvm- --prefix=/home/andrelct/apps/llvm-gcc/build/
--bindir=/home/andrelct/apps/gnat-2007/build/bin
--enable-llvm=/home/andrelct/apps/llvm
Thanks
Hi Andre,
In file included from ../../gcc/llvm-backend.cpp:23:
../../gcc/llvm-internal.h:31: fatal error: vector: No such file or directory
compilation terminated.
line 31 of llvm-internal.h is:
#include <vector>
so if that's failing then your C++ compiler is somehow borked.
How did you arrange to use the right gcc for the build? Maybe
that's getting in the way of g++ somehow.
Do you have an idea of what it is?
I suggest you do like this: make sure the system C++ compiler is working
and in your path. To use the Ada enabled gcc for building do:
export PATH=/home/andrelct/apps/gnat-2007/bin:$PATH
before configuring, building etc. (Assuming this is where the GNAT
GPL 2007 gcc is).
My new config is
../configure --enable-languages=c,c++,fortran,ada --disable-bootstrap
--disable-nls --disable-multilib --enable-checking
--program-prefix=llvm- --prefix=/home/andrelct/apps/llvm-gcc/build/
--bindir=/home/andrelct/apps/gnat-2007/build/bin
Not sure why you are using --bindir here?
--enable-llvm=/home/andrelct/apps/llvm
Ciao,
Duncan.

Hey Duncan,
my g++ is broken, but I used g++-4.3 and it worked. Unfortunately there is another problem. If I compile with llvm-gcc the ali file resulting says V "GNAT Lib v4.2" on the first line. So it compiled version 4.2 and so gnatbind and gnatlink does not work because they are version 4.1.3.
If I compile the same program using gcc of the gnat2007, the ali file says that the version is 4.1.3, the right one.
Somehow the lib version that llvm-gcc is being compiled is 4.2. Do you know how to get the 4.1.3 version?
Thanks

yes, that's because llvm-gcc is based on gcc 4.2.
So it compiled version 4.2 and
so gnatbind and gnatlink does not work because they are version 4.1.3.
When you built llvm-gcc, you also built appropriate versions of gnatbind
and gnatmake. Don't mix versions: use
export PATH=path_to_wherever_llvm_gcc_lives:$PATH
before doing stuff. Since the gnatbind and gnatmake you built should be
there too, you will use consistent versions and all will be fine.

Version 4.1.3 is the wrong one: it is the version of GPL 2007. You
want 4.2 because that's what llvm-gcc is.
What are you trying to compile by the way?
Also, does "cd llvm_gcc_build_directory/gcc && make -k check-acats"
work? Do you get any test failures?
Ciao,
Duncan.
