ifort Mac OS X linking problem

[Tom_S_1]

Hi,


I am trying to compile some code I wrote for my research on an Intel Mac Pro running Mac OS X Tiger 10.4.11 using ifort. As I managed to this before on Fedora 8 with ifort, as well as on this Mac Pro using gfortran 4.3, I expected no problems. However things to took a different turn...

My software consists of a shared library, written in C, Obj-C and fortran, and a bunch of executables written in C and Obj-C that link to this library.

I compiled the library without problems but when I want to try the executables I receive a bunch of ld errors like this:

FYI: libxmi-quant.dylib is the name of my shared library.

I used the default installation of the Intel Fortran and the environment is set correctly.

Any help would be greatly appreciated!

Tom,

The runtime is not finding the Intel runtime libraries, such as libifcore.dylib. Before you run,

source /opt/intel/fc//bin/ifortvars.sh

This will set up the dynamic library path to include the Intel Fortran Runtime Libraries (RTL).

If you use the 64 bit compiler, use the path to /opt/intel/fce//bin/ifortvars.sh

Let us know if this fixes the problem (it should).

[Tom_S_1]

Thanks for the quick answer ron.

This doesn't fix the problem though.

I already added that line to my .bashrc so I'm pretty sure the environment is OK. $DYLD_LIBRARY_PATH is defined and points to the right directory.

Tom

[Ron_Green]

Interesting. Would otool -L on your dylib give any hints:

otool -L libxmi-quant.dylib

Also, is LD_LIBRARY_PATH set correctly at runtime? (will indicate if the ifortvars.sh was sourced correctly)

[Tom_S_1]

This is the otool -L output:

libxmi-quant.dylib:

And the LD_LIBRARY_PATH is also set correctly.

[Ron_Green]

when you compiled on Tiger, do you use the 32bit compiler in path /opt/intel/fc/....etc...?

and what compiler version do you have? ifort -V

[Tom_S_1]

I used the 32 bit compiler

output of ifort -V:

Intel Fortran Compiler for applications running on IA-32, Version 10.1 Build 20080312 Package ID: m_fc_p_10.1.014

[Bonnie_A_Intel]

While we run some testson this problem, I just wanted to mention that in the one case where we saw something similar on a Tiger system, the problem went away after logging out and logging back in.

[Tom_S_1]

Thanks for investigating this problem.


The logging out/logging in doesn't work though.

I was wondering if there was any resolutin to this problem. I am having a similar issue linking my application to the included libguide.dylib. I'm running the 64-bit ifort. 10.0.016

Hi Jeff,

First, just a heads-up. If you are using Leopard, then you need to upgrade to our latest 10.1 update. Our 10.0 compiler does not support Leopard. I do not know if that will affect your issue.

What run-time errors do you see?
