Hi Folks:

I would like to be able to compile source programs to 64 bit binaries on 
the solaris sparc platform using gcc 3.x.   In the past I've given what 
I've thought we're the correct arguments to the compile program, but 
when it links the program it complains about the linker not compiling 64 
bit programs.   So I guess my question is how I can get a version of gnu 
ld compiled that will support 64bit binaries...

Any hints on how to accomplish this would be greatly appreciated, 
including recommended reading if that is necessary.


Thanks for the help.

The manual says:
      -m32
      -m64
          Generate code for a 32-bit or 64-bit environment.  The
          32-bit environment sets int, long and pointer to 32
          bits.  The 64-bit environment sets int to 32 bits and
          long and pointer to 64 bits.

Which parameter do you give for compiling and linking in 64Bit mode ?

Sun's compilers are a better choice...

GNU Ld isn't required.  Use the one provided by Solaris.

It would help if you told us what you did.

Assuming you used gcc -m64, don't forget that you also have to link with
64-bit libraries.

Hadn't thought of that...

Alright I have gcc-3.3.2.   I'm passing CFLAGS=-m64 to gcc  and I'm 
using LD_OPTIONS=-64.

My compile gets to this point when trying to compile mysql 4.0.17

64 bit

ld: fatal: file 
/usr/local/lib/gcc-lib/sparc-sun-solaris2.9/3.3.2/crt1.o: wrong ELF 
class: ELFCLASS32
ld: fatal: File processing errors. No output written to .libs/mysql
collect2: ld returned 1 exit status

Now this is using /usr/ccs/bin/ld as my linker.

I do have /usr/local/lib/gcc-lib/sparc-sun-solaris2.9/3.3.2/sparcv9/crt1.o

How can I get the 64 bit support and bypass 32bit support.

Thanks,

Do a 'file /usr/local/lib/gcc-lib/sparc-sun-solaris2.9/3.3.2/crt1.o'.
I'm imagining this is a 32-bit ELF file.  There should be a 64-bit copy
in ...3.3.2/sparcv9/crt1.o

You cannot mix 32 bit and 64 bit libraries in the same executable.

I'm not certain why the compiler is trying to link that library.  I
would imagine that there should be a 64 bit version of that library if
the compiler is capable of producing 64 bit code, and it should be using
that version.

That's exactly correct.   It is a 32bit library.   In one directory up 
sparcv9  is crt1.o 64bit.   How do I compile it such that it knows that 
it should use files in that directory rather than the another.   I was 
wondering if maybe I had to pass -mcpu=sparcv9, but that doesn't seem to 
work for me.   Unless I'm specifying it incorrectly.

Thanks for the help.

There should be two copies of crt1.o under that directory; one for
sparcv9 and one ordinary one; the linker determines the type of
binary from the first object it finds.

Hm, then there's something wrong with the spec file or are you not linking
with gcc -m64?
