Hi All
I'm hoping one of the experts here can help me out with this problem...
I've built a Linux to Sun cross compiler using gcc-3.4.4. I've done this
before and had it work, but some problems have cropped up.... In the past
I've been able to build simple programs (ie - "Hello World") on linux and
execute them under Solaris on Sparc hardware, but it's quit working.
I'm using gcc-3.4.4 configured as follows:
/cdl/apps/.software/linux/gcc-3.4.4-x86-sparc/sparc-sun-solaris2.9/bin/g++
-v
Reading specs from
/cdl/apps/.software/linux/gcc-3.4.4-x86-sparc/lib/gcc/sparc-sun-solaris2.9/3.4.4/specs
Configured with:
../gcc-3.4.4/configure --host=i686-pc-linux-gnu --target=sparc-sun-solaris2.9
--with-sysroot=/cdl/apps/.software/linux/gcc-3.4.4-x86-sparc-build/sysroot
--with-gnu-as --with-gnu-ld --enable-languages=c,c++ --prefix=/cdl/apps/.software/linux/gcc-3.4.4-x86-sparc
Thread model: posix
gcc version 3.4.4
[EMAIL PROTECTED] helloworld]$
The "sysroot" directory contains all of the goodies from /usr/lib,
/usr/include, etc from a Sun box running Solaris 9. I can send a complete
file list if anyone wants it I was really careful to make sure that all of
the symlinks that were in these directories on the Sun machine were
preserved. When I try to build a simple hello world program:
#include <stdio.h>
int main(void)
{
printf("Hello World!\n");
return 0;
}
I get the following errors:

(when compiling more complex examples I get a similar problem for -lrt)
Can anyone shed some light on this? I've done some googling and turned up
some talk of 32 bit versus 64 bit architectures, but trying the build with
an -m32 or -m64 made no difference. I've had this work before, so I'm
probably missing something obvious...
Thanks
