Errors compiling TR Solver Fortran-77 example

Jorge1 — Fri, 01 Mar 2013 18:05:05 GMT

Hi all

I copied the TR Solver Fortran-77 example: "ex_nlsqp_f.f" to my home directory and tried to compile it but I get a lot of errors as is shown below. I would appreciate any help. I add the option "-logo" to provide information about the installed product in the output.

Thanks you all!

Jorge

There are some extraneous spaces in your command line as shown above; for example, you have "libmkl_solver_sequ ential.a", with a space between "sequ" and "ential". Secondly, your specify the -L path option but then list the full paths to the library files, so the -L option has no real effect on what follows.

Considering that you are working on a simple example, you could try the much simpler compile/link command:

[bash]$ ifort -mkl ex_nlsqp_f.f -o ex_nlsqp[/bash]

Zhang_Z_Intel — Fri, 01 Mar 2013 20:05:00 GMT

There are problems in your command line. You should try this:

ifort -I/opt/intel/mkl/include -o ex_nlsqp_ f ex_nlsqp_f.f -Wl,--start-group /opt/intel/mkl/lib/ia32/libmkl_intel.a /opt/intel/mkl/lib/ia32/libmkl_sequential.a /opt/intel/mkl/lib/ia32/libmkl_core.a -Wl,--end-group -lpthread -lm

There is an online tool to help you sort out the link line arguments: http://software.intel.com/sites/products/mkl/

Thanks for your helpful and quick replay!!! The extraneous spaces in my command line emerged during the process of copy and paste. Sorry about that! I´ll be more careful next time. The compile/link command you proposed work perfectly at compilation time but at run time it gave me the error:

./ex_nlsqp: error while loading shared libraries: libmkl_intel.so: cannot open shared object file: No such file or directory

I avoided the error modifying the compile/link command linking all libraries statically:

$ ifort -mkl -static-intel ex_nlsqp_f.f -o ex_nlsqp

It would be interesting to find a solution linking all libraries dynamically.

./ex_nlsqp: error while loading shared libraries: libmkl_intel.so: cannot open shared object file: No such file or directory

The solution is simple. If $LD_LIBRARY_PATH is not set, set it to the directory containing libmkl_intel_so. If the variable is set, add the directory to it by using the command: [bash]export LD_LIBRARY_PATH={path to Intel MKL lib directory}:$LD_LIBRARY_PATH[/bash]

Sourcing either the compilervars or mklvars script supplied with Intel compilers would set LD_LIBRARY_PATH.

Hello everyone,

I'm giving up! my goal was to compile and run some fortran codes using dfti. At this point I succed compiling and linking but I do ha a run time error.

Heredown details:

Platform mac os x lion

software: composer_xe_2013.1.119

compiling script:

ifort -o exec $1 $2 $3 -L/opt/intel/composer_xe_2013/mkl/lib /opt/intel/composer_xe_2013/mkl/lib/libmkl_intel_ilp64.dylib -lmkl_intel_thread -lmkl_core -liomp5 -lpthread -lm -I/opt/intel/composer_xe_2013/include -i8

run time error:

dyld: Library not loaded: libmkl_intel_ilp64.dylib
Referenced from: /Users/erwin/calculos/Maxwell_calc/./exec
Reason: image not found

That it is! Can you help me please guys?

Thanks,

Erwin

Probably, the environmental variable DYLD_LIBRARY_PATH is not set or is not set to include the flagged shared library's path.
