scheck complains about "No such file or directory" for php files being tested

[truebit]

I want to use scheck for my project.
So I firstly generated graph file with command below:
./codegraph -lang php -build ~/Documents/work/repo/server_code -o ~/Documents/work/repo
The graph_code.marshall generated in ~/Documents/work/repo/graph_code.marshall

Then I tried scheck on my project code:
/scheck -with_graph_code ~/Documents/work/repo/graph_code.marshall -php_stdlib ./data/php_stdlib ~/Documents/work/repo/server_code

It failed with Fatal error: exception Sys_error("DataStruct.class.php: No such file or directory")
But DataStruct.class.php is actually in root of project dir ~/Documents/work/repo/server_code

It's because codegraph finished with lots of errors, the incorrect generated graph_code.marshall should be denied by scheck.
I do not know whether it would work if all errors in pfff.log fixed.
