Compiling with ifort

[angiekia]

Hello,

We have the new Intel compiler (11.0) installed at our Linux machines at University. The previous version we were using was 9.1.043. In order to compile something i was running the following commands (using libraries as well)

ifort -c *.f

ifort **.o **.o -L. -l** -o **

./**

With the new one, when i run the first command, I get

**.f(103): (col. 7) remark: BLOCK WAS VECTORIZED.

**.f(147): (col. 7) remark: LOOP WAS VECTORIZED, and another 100 of these.

Then i move one to the second line and i get this

ld: skipping incompatible ./lib**.a when searching for -l**

ld: cannot find -l**

However lib**.a exists in the folder and everything was working before.

What do I have to with the new compiler to make it to work again?

Any help would be appreciated.

Thanks

This generally indicates you attempted a mixture of 32- and 64-bit objects. While the x86_64 linux has support for both 32- and 64-bit execution, it doesn't support linking them together.
Supposing that 'file *.a' indicates these are 64-bit objects, you must use the 64-bit compiler, such as you would get on PATH by
'source /opt/intel/Compiler/11.0/081/ifortvars.sh intel64'
You could check which compiler you have active by 'ifort -V'

I was using the intel 64 and changing to 32 bit solved the problem. Thanks!

As to the * (col. 13) remark: LOOP WAS VECTORIZED. can i somehow turn this off- so as not to see them on the screen? I have a lot of fortran codes that are compiled every time - and it justs clutters my screen.

Thanks again!!

-vec-report0 turns off vectorization messages. Apparently, it's the default for the next release.

Thanks so much for your help! Everything is running smoothly now...
