ld: codegen problem, can't use rel32 to external symbol in _MAIN_

[hghu]

Hello,

I tried to read a big dataset with a Fortrn program which works very well on the Linux machine (Lahey Fortran compiler), but there is a problem when running it on the MAC with ifort compiler. Error messege:

ifort -mcmodel=large readdata.f
ld: codegen problem, can't use rel32 to external symbol in _MAIN__ from /var/folders/tS/tSn88ZqRE6822yVNcVSo2E++0+A/-Tmp-//ifortw82CxZ.o

ifort -V

Any suggestions?

Thanks

The -mcmodel option is not supported on Mac OS. Versions prior to 11.1 incorrectly accepted, but version 11.1 now ignores and issue a warning as shown below.

Ok. The issue you are facing relates to compiling a program containing >2GB of static data.

There were a couple of issues at play in the past regarding this involving large static arrays. At least one fix was provided in the Intel compiler 11.0 release for one aspect of this error, but nothing in the 10.1.024 (the last 10.1 update).

Can you upgrade to our 11.1 compiler?

If not, there is a possible work around of either placing static arrays into a MODULE or allocating the arrays dynamically using ALLOCATE.

Thank you very much!
