"feconv" error

[fkoushan]

Hello, I am trying to use feconv to change my mesh file format from .msh to .unv. But after unzipping the directory, and running the make command in my mac, ( make -f Makefile.gfortran.osx-10.11-elcapitan), I get the following error every time I try feconv command:

$ feconv -gm examples/dt5.msh dt5.unv -bash: feconv: command not found

even though "feconv" is generated in my directory after "make" command is run. Any ideas what could have gone wrong in this process?

Hi,

depending on your shell configuration file, the OS could require that you run ./feconv instad of feconv.

Best, Francisco Pena

Hello Francisco, Thanks for your reply - I did try ./feconv command as well. and here is the error I get:

Foroozans-MBP:FEconv-master foroozankoushan$ ./feconv -h dyld: Library not loaded: libbasicmod.dylib Reason: image not found Abort trap: 6

Is the library that is being referred to supposed to be loaded during "make" command run? Thanks,

[fran-pena]

Hi,

you have to include the path to the library in the variable DYLD_LIBRARY_PATH. That is, write something like

export DYLD_LIBRARY_PATH=$DYLD_LIBRARY_PATH:

where is the path to the lib/ folder inside feconv.

Best, Francisco

Hello, Could I type the address to the library as I am inside the feconv directory, or do I need to be somewhere else? I typed the following command line when inside the feconv-master directory: Foroozans-MBP:FEconv-master foroozankoushan$ export DYLD_LIBRARY_PATH=$DYLD_LIBRARY_PATH:/Users/foroozankoushan/Documents/FEconv-master/lib

then tested it with: ./feconv -h

and got the same error message as before: Foroozans-MBP:FEconv-master foroozankoushan$ ./feconv -h dyld: Library not loaded: libbasicmod.dylib Referenced from: /Users/foroozankoushan/Documents/FEconv-master/./feconv Reason: image not found Abort trap: 6

Thanks,

Hi,

The problem is how to find a dynamic library in OS X. I cannot make a test in that platform at this moment. To redefine the variable DYLD_LIBRARY_PATH was the suitable way to do it that I found in the specialized forums. Please, check whether you are using OS X 10.11 El Capitan, the OS X version where I tested it.

Best,

@fkoushan @fran-pena I had the same error. It is actually NOT recommended to change the DYLD_LIBRARY_PATH variable. An alternative is this:

The libbasicmod library is situated in the basicmod/lib folder. Move to the FEconv-master folder in the terminal. In order to include this library when running for feconv, you can simply check, where it is searched for at the moment by:

otool -L feconv

The first line gives an indication to where the build thinks this library is. Change that using

install_name_tool -change current_direction_where_it_is_looking basicmod/lib/libbasicmod.dylib feconv
