lld-link: error: section larger than 4 GiB

[JulieMarieC]

Hello,

I was using ifort compiler, but i have seen the message that it will be deprecated, so I'm trying to use ifx instead, but I get this error:

lld-link: error: section larger than 4 GiB: .data

Do you have any suggestions?

Best regards,

Julie

Do you really have a static variable (COMMON, most likely) larger than 4GB?

This isn't a compiler issue - add -mcmodel medium to the compiler options.

[JulieMarieC]

It seems that '-mcmodel medium' is not recognized by ifx compiler.

[Barbara_P_Intel]

On Linux the syntax is "-mcmodel=medium". There is no equivalent option for Windows. See this section in the Fortran Developer Guide and Reference.

[JulieMarieC]

Thanks for your answer. I will in the next few months, maybe there will be an update that will allow this option for Windows.

[Steve_Lionel]

No, there won't - Windows has a hard limit of 2GB static code and data, due to the design of the executable format. Use ALLOCATABLE arrays instead of very large static arrays.

[JulieMarieC]

Ok, thanks for this precision.

So I don't know why it works with ifort but not with ifx: maybe it is linked to the fact that with ifort, our code is compiled for win32, but we have to compile for x64 with ifx?

It doesn't work with 64-bit ifort either.
