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 rule.ninja, it works well. How could I push this fix to mainline? 于2018年8月3日周五 上午7:16写道：

Hi,

Sorry, the docs at https://sel4.systems/Info/CAmkES/GettingStarted.pml​ ​are completely out of date. I'll look into getting them removed.

The second set of docs ( https://docs.sel4.systems/CAmkES/) https://docs.sel4.systems/CAmkES/​ 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 (https://docs.sel4.systems/Docker.html), does it work?

​Cheers,

Anna.

Hi, When I followed this tutorial: https://sel4.systems/Info/CAmkES/GettingStarted.pml The error is:
