llvm dev - Dec 2010 - [LLVMdev] Building LLVM-GCC on Linux/PowerPC failed

Hi, folks

    I am trying to build LLVM-GCC 4.2 on a Linux/PowerPC machine.
Actually, the PowerPC is a PS3. The source was downloaded from
http://llvm.org/releases/2.8/llvm-gcc-4.2-2.8.source.tgz

  Here is my system information and configuration options:

----------------------------------------------------------------------
$ uname -a
Linux ps3 2.6.32-rc2-00995-g96ebbe6-dirty #2 SMP Fri Oct 2 15:12:28 CST
2009 ppc64 Cell Broadband Engine, altivec supported GNU/Linux
$ gcc --version
gcc (Gentoo 4.3.2-r3 p1.6, pie-10.1.5) 4.3.2
$ ../configure --prefix=/tmp/chenwj --enable-langugaes=c,c++
-----------------------------------------------------------------------

  And here is the compiling error,

-----------------------------------------------------------------------

                 from /usr/include/stdio.h:28,

  Any suggestion appreciated.

Adding -m64 to CFLAGS should help.

CFLAGS=-m64 ../configure --prefix=/tmp/chenwj --enable-langugaes=c,c++

Also check that there isn't a -m32 amongst CFLAGS

Hi, Csaba

  Thanks for the tip. My PS3 workstationn is installed a 32-bit OS. I will
install a 64-bit OS soon and try what you said.

  Thanks again.

Yes, the kenel is 64 bit, but you may still have a pure 32
bit userspace (thats what my dual G5 PowerMac running Linux
has).

Does your maching have directories like /lib64 and /usr/lib64?

If you compile a program like:

    #include <stdio.h>
    int main (void) {
        printf ("sizeof (void*) : %zd\n", sizeof (void*)) ;
        return 0 ;
    }

what is the size of a void pointer?

Does this change if you add -m64 to the gcc command line?

Here genmodes is already built via llvm. Given that there is no proper
ppc-linux/ppc64-linux codegen support, it's not unexpected that you're
seeing a segfault here.

Try to configure with --disable-bootstrap

Don't know if it helps, but clang at least builds nicely. Unfortunately
I have a 32bit runtime installed and this seems to cause problems
somewhere - clang defaults to 64bit assembly (if I understood the output
correctly), and the assembly made from running 
'clang --ccc-host-triple=powerpc-linux-gnu' is not accepted by the
default system assembler. It might work better on a 64bit system. 

And I probably should file a bug. Is ppc32 still maintained?

Due to reasons I outlined in my prev. e-mail. Now you can notice that
the build proceed much further. Try to add --disable-libmudflap as well.

Hi, Anton

  Finally, I built LLVM-GCC 2.8 on a Linux/PS3 machine.

  I just put my configuration options here,

---------------------------------------------------------------------------
../llvm-gcc-4.2-2.8.source/configure -prefix=/tmp/chenwj/install
--disable-bootstrap --disable-libmudflap --disable-multilib
--disable-libgomp --program-prefix=llvm-
--enable-llvm=/tmp/chenwj/install --enable-languages=c,c++
---------------------------------------------------------------------------

  Hope this help others. :)

chenwj
