Dear all  
I run the XIOS training cases ([svn - Revision 2326: /XIOS/xios\_training](http://forge.ipsl.jussieu.fr/ioserver/svn/XIOS/xios_training/)) with XIOS 2.0. The cases of hand-on 1 to hand-on 1 can be successfully make and run, but when I make hand-on 7, an error message appears as follows:

```nohighlight
[sio_xmzhang_4@ln0%tianhe2-C hands-on-7]$ make
mpif90 -I/WORK/sio_xmzhang_4/Build_NEMO/xios-2.0/inc -I/WORK/app/netcdf/4.4.1/03-CF-gcc-5.4.0-par/include -c generic_testcase.f90
mpif90 -o generic_testcase.exe generic_testcase.o -L/WORK/sio_xmzhang_4/Build_NEMO/xios-2.0/lib -lxios -L/WORK/app/netcdf/4.4.1/03-CF-gcc-5.4.0-par/lib -lnetcdff -lstdc++
generic_testcase.o: In function `init_domain_dynamico.3598':
generic_testcase.f90:(.text+0xd088): undefined reference to `xios_get_current_context_'
collect2: error: ld returned 1 exit status
make: *** [generic_testcase] Error 1
rm generic_testcase.o

```

I’d appreciate any suggestions as to how to solve this problem.  
Thanks

Wangy

Dear @wangy,

Your problem is strictly not related to NEMO so it is out-topic in the context of this forum.  
To reach XIOS developers, I suggest to post your support request on the XIOS users mailing list : [xios-users@forge.ipsl.jussieu.fr](mailto:xios-users@forge.ipsl.jussieu.fr)
