"relocation trucation" using mcmodel=medium on a EM64T

[mkcolg]

Hello,

I'm having trouble getting a program containing a large array to link even though I'm using "-mcmodel=medium" on an EM64T running SuSE9.1. Am I missing a flag or are large static arrays not supported?

Thanks,
Mat

test2.f:
program main
integer a(600000000)
a(1) = 10
stop
end

ifort -mcmodel=medium -O0 test2.f -o test2 -V

Hello

I am having a similar problem. Does anybody have an explanation or a solution ?

Thanks

Your test case has no problem with l_fce_pc_8.1.025 running on RH EL3_U3, which has a much older version of binutils. SuSE 9.1 is supported by 64-bit ifort, but it won't install on my EM64T machine. You might consider submitting the problem report on premier.intel.com.

The older version of binutils included in RHEL3 is not reliable for generating shared libraries for EM64T (x86_64). Numerous changes (mostly improvements, it appears) to the x86_64 infrastructure are included in binutils 2.15, so I am using 2.15 on my RHEL3 box. Unfortunately this means I get the same error reported above.

I raised this as an issue on my Premier support pages and was told that this was a known issue and to use -i_dynamic

Seems to have solved the problem for me on SuSE 9.1 X86_64 EM64T

Couldn't see this answered anywhere else on the forums or in the known issues for the compiler so I thought I may as well post it here.
