In order to compile the Osiris follow the instructions.
Change to the Osiris directory:
cd osiris
Compile all components by issuing a command:
make
This command builds all modules as executables: ./osiris (the integrated Controller and Editor), ./generator/ogener (the Generator) and ./validator/ovalid (the Validator).
Furthermore the gKheops should be patched. To do this copy the file ./gkheops/gkheops_v1.0_osiris_patch.gz from the Osiris source directory to the gKheops source directory (/src/gKheops in example below).
cp ./gkheops/gkheops_v1.0_osiris_patch.gz /src/gKheops
Change a current directory to the gKheops source and issue:
gzip -dc gkheops_v1.0_osiris_patch.gz | patch -p0
And then recompile the gKheops according to the gKheops user's manual.
