1. Since solaris x86 image did not have 64 bit binutils. I have built the
latest version of 64 bit binutils using the default gcc compiler that comes
with the OS distro.
"Latest version"? What was that?
I get the following error:
amd64/libgcc_s.so.1.tmp amd64/libgcc_s.so.1 && ln -s libgcc_s.so.1
amd64/libgcc_s.so
/usr/lib/amd64/crti.o: file not recognized: File format not recognized
collect2: ld returned 1 exit status
I got this same error with the existing :
[root@Dell gcc]# /usr/local/i486-solaris2.10/bin/ld -V
GNU ld version 2.16.91.0.7 20060317
Supported emulations:
elf_i386_ldso
elf_i386
elf_x86_64
I had used for old gcc-3.x's ... But after updating to :
[root@Dell gcc]# /usr/local/i686-solaris2.10/bin/ld -V
GNU ld (Linux/GNU Binutils) 2.19.50.0.1.20081007
Supported emulations:
elf_i386_ldso
elf_i386
elf_x86_64
the error disappeared ! I built my GCC(s) as cross-
compilers on Linux, so these binutils versions are those
"Linux-binutils" in 'ftp.kernel.org'...
The 64-bit multilib-support seems to have appeared with
gcc-4.0, in gcc-3.4.6 only the 32-bit support was present.
BTW, using a '--with-cpu=k8' or something was obligatory,
otherwise the build stopped with a notice about the "selected
CPU not being capable to run 64-bit binaries"...
