Hi, all
Can anyone help me to resolve this problem?
When I compile a program with .bss segement larger than 2.0GB, I get the
following error message from GNU linker (binutils-2.15).
(.text+0x305): In function `sta_':
: relocation truncated to fit: R_X86_64_32S plot_
......
I upgrade the assembler and the linker from binutis-2.17, then get the
message below.
STA.o: In function `sta_':
STA.F:(.text+0x305): relocation truncated to fit: R_X86_64_32S against
symbol `plot_' defined in COMMON section in STA.o
So, I modified the binutils-2.17/bfd/elf64-x86-64.c and rebuild the linker
to ignore the relocation errors. Though the executable generated,
segementation fault occurred during execution.
Here is the configuration of my computer:
CPU: Intel(R) Xeon(R) CPU 5150 @ 2.66GHz
OS: Linux mds 2.6.9-34.EL_lustre.1.4.6.1custom #3 SMP Fri Jul 13 15:27:27
CST 2007 x86_64 x86_64 x86_64 GNU/Linux
Compiler: Intel C++/Fortran compiler for linux 10.0
I also wrote a program with large uninitialized data -- more than 2.0GB.
It passes after linked with the modified linker. The source code is appended.
Try using -mcmodel=medium
Richard.
#define N 0x05fff
double a[N][N];
int
main ()
{
int i, j;
double sum;
for (i = 0; i < N; i+=5)
for (j = 0; j < N; j+=5)
a[i][j] = 2* i*j + i*i + j*j;
sum = 0.0;
for (i = 0; i < N; i+=5)
for (j = 0; j < N; j+=5)
sum += a[i][j];
printf ("%f\n", sum);
}
Best regards,
Canqun Yang
