error on CONVERT2SYRTHES making

i'm working on caelinux11.
I need to use convert2syrthes function to convert my mesh file.med 2.3 that i've exported from salome5.
I take position in terminal in /opt/syrthes/convert2syrthes and write make.
I receve this errors (in attachment). Anybody knows the problem?
I think the problem is hdf5 and med library but in spite of my attempts the errors continue.

ERRORS:

Hello,

If there is already an executable, you may not need to run "make". Otherwise, judging by the error message, you forgot to run make as root or using "sudo".
