problem building x64 executable [solved]

[os64dev]

hi all,

When using the linkerscript posted below i get the folowing error messages:

obj/core/core.co: In function `crt::main()':
core.cc:(.text+0x115): relocation truncated to fit: R_X86_64_32 against `.rodata
.str1.1'
lib/libc.lib(printf.co): In function `printf(char const*, ...)':
printf.cc:(.text+0x534): relocation truncated to fit: R_X86_64_32 against `.text

If i compile with the -fPIC compiler flag everything works. My question:
Can somebody explian to me why this is and how to solve it. I don't want to have position independant code for every executable.

i have build a cross compiler btw.
