linking Problems: /opt/intel/fc/9.0/lib/for_main.o(.text+0x0):./src/libfor/for_main.c ...

Hi,
I have a problem linking a mixed c/fortran code:
Here is the error message:

ifort -oBin/field.exe Objects/menu_transformations.o Objects/menu_visualizations.o Objects/dummy_hdf.o Objects/u_functions.o Objects/u_menu.o Objects/u_menu_main.o Objects/diff_op_w2d.lib.o Objects/init_w2dlap_filt.o Objects/init_w2drec_filt.o Objects/simulations_w2d.lib.o Objects/init_w1dint_filt.o Objects/init_w2dpois_filt.o Objects/mask.lib.o Objects/w_t_adapt_2dw.lib.o Objects/fftw3.o Objects/main.o Objects/field.o Objects/gnuplot.o Objects/palette.o Objects/ppm.o Objects/dx.o Objects/input_bin.o Objects/input_output.o Objects/slave.o -lfftw3 -LSources/Field_includes/fftw/lib/ -lm

The file Objects/main.o is created with gcc:

No error messages or warnings here.

Thank you for help.

Add to the ifort command -nofor_main

Thanks, it works.

Steve, i had the same problem but my Program is in Fortran code only. I'm using eclipse 3.4 with intel fortran compiler professional edition v.11 .

Any Idea?

Thank you!

Steve is out at the Intel Developer Forum (IDF) in San Francisco this week, so I'll take a stab at this.

My guess is that Eclipse is not searching the library path to the Intel Fortran compiler libraries. Prior to starting Eclipse, do you 'source /opt/intel/.... ifortvars.sh' - perhaps put that into your .bashrc file to make sure LD_LIBRARY_PATH includes the Intel library path. Now if you are doing this, perhaps eclipse is ignoring LD_LIBRARY_PATH. Is there some linker setting that allows you to specify additional library paths? If so, add the path to the /lib directory for your compiler.

Thanks for fast help Ronald.

I did the command 'source /opt/intel...ifortvars.sh intel64' after the installation but i'm not sure that i put it in my .bashrc file. I need to edit it and add what exectaly?

Sorry for my reckless and poor information. =/

Ronald, seems like the problem is with eclipse. I add the LD_LIBRARY_PATH to the .bashrc file and now i can compile the program via command line but with eclipse it's the same problem. I'm going to try the second thing you said...

Thanks for all!

To solve the problem with eclipse and lib do this in eclipse:

Go to Run As -> Environment -> New
Then put,
Name : LD_LIBRARY_PATH
Value: "your lib path":$LD_LIBRARY_PATH

In my case was:
Value: /opt/intel/Compiler/11.1/046/lib/intel64:$LD_LIBRARY_PATH

Thanks again Ronald!
