Thank you for you reply Anna.Lyons . I read the url what you update, When I compile the ninja, 
it output a error: 
../tools/seL4/elfloader-tool/src/string.c:97:29: error: expected ';', ',' or ')' before 'dest'
 void *memcpy(void *restrict dest, const void *restrict src, size_t n)
Since the restrict keyword was introduced in c99, so we have to add flags -std=gnu99, to compile
this code.
When I add this flags to compile of, it works well.
How could I push this fix to mainline?

Sorry, the docs at​ are completely out of date. I'll look into getting them removed.

The second set of docs (​ are correct. I just reproduced building correctly on my machine. 

Can you please reply with the results of the command 'repo manifest'  so I can check the revisions of the code you are working with? It could also be a dependency issue - if you try building the example using our docker image (, does it work?
