RE: Error building 64 bit gcc in sparcv9-sun-solaris2.8

[Karthikeyan M. D]

Hi,
	Thanks for the reply. I did a cleanup only in toplevel libiberty
directory and not in pic directory inside and built libiberty with
stage1/xgcc and then did the bootstrap again, this time it failed in the
stage comparison saying the object files differs (error below), need the cp
directory to be rebuilt with stage2 xgcc.

Thanks,
Karthik

You told it the build system is sparcv9 so it assumed that the bootstrap
compiler generated sparcv9 code. It didn't; your bootstrap compiler
generates 32-bit sparc code. Hence the top level libiberty was generated
as 32-bit and you're now attempting to link it to 64-bit code.

Clean out the top level libiberty directory and reconfigure and build
using the xgcc you've just built, i.e. something along the lines of:

   CC="../gcc/stage1/xgcc -B../gcc/stage1/" \
       <srcdir>/libiberty/configure <etc>
   make CC="../gcc/stage1/xgcc -B../gcc/stage1/"

(or throw in stage1/ as necessary; can't remember)
Go back and restart the bootstrap; it should then complete (or, at
least, it has for me before from this situation.)

Other ways of building sparcv9:

  1. Install a multilibbed 32-bit gcc which understands -m64 (3+, I
     think). Then:

      CC="gcc -m64" ../gcc-3.0/configure <etc> sparcv9-sun-solaris2.8
      make bootstrap CC="gcc -m64"

     This will build the top level libiberty (and stage1) as 64-bit
     straight off.

  2. Generate a cross-compiler to sparcv9 then use that as the build
     compiler to bootstrap a 64-bit gcc. (Don't know if you'd need a
     complete toolchain or not - never tried this.)

In my opinion, you'd probably do better with a multilibbed sparc
compiler and the '-m64' switch than a sparcv9 compiler. But, as you say,
lots of people build sparcv9. And if you want 64-bit sparc, you'd be
better off with a gcc 3.1 snapshot; 3.0x has (I think) incomplete
support for the 64-bit sparc ABI.

Hi,
	The error was because gnu ranlib appear before /usr/ccs/bin/ranlib,
once I set the PATH properly it proceeded further but stuck in some other
place because of below error.

Error building 64 bit gcc in sparcv9-sun-solaris2.8

[Karthikeyan M. D]

Hi,
	I've read few people's mail who has built 64 bit gcc in sparc
platform successfully and I tried building 64 bit gcc with both 3.0 source
and 3.0.4 source in sparcv9-sun-solaris2.8 and got the below error in both
the cases. I tried building with both gcc-3.0 (32 bit) and gcc-2.95.3 and
got the the same error. I have all the latest GNU tools (make-3.79.1,
autoconf, automake, autogen, flex, bison, etc.) The error says libgcc.a is
an unknown file type, but when I do file command on that it says it is a
library archive. I used the following commands to configure and build.

../gcc-3.0/configure --prefix=/tmp/fs/gcc64 \
		      --enable-shared \
		      --enable-languages="c,c++" \
		      --with-as=/usr/ccs/bin/as \
		      --with-ld=/usr/ccs/bin/ld \
		       sparcv9-sun-solaris2.8

make bootstrap

Any help is highly appreciated.

Thanks,
Karthik
