Relocation truncated to fit

[Gabriele_B_]

Hi,

I tried to increase the size of some arrays in COMMON, but when I compile the code I got many messages like this:

for_diags_intel.c:(.text+0x13aa): relocation truncated to fit: R_X86_64_PC32 against symbol `message_catalog' defined in COMMON section in /usr/local/intel/Composer/composer_xe_2013_sp1.2.144/compiler/lib/intel64/libifcore.a(for_diags_intel.o)

What does it mean? how can I avoid it?

Thanks

GB

Try adding "-mcmodel medium" to your compile/link options. This is needed when you have static data that exceeds 2GB. As an alternative, consider using allocatable arrays rather than huge COMMONs.

Thanks,

the first method works.

Is it possible that this option disable the -traceback ? Should I use -g -O2 or -g -O0?

Thanks

No, -mcmodel medium should have no effect on traceback. -g implies -O0.
