Build Instructions

[21212124]

How do they apply the patches to the OP-TEE build system, client library and OS? what is there to do?

[SilvaMatteus]

Hello @21212124. When I was applying the patch on the build repository I got the following error: error: corrupt patch at line 124 Have you experienced the same?

[21212124]

I have no idea, but if you can get it started the fuzzer, let me know. thanks.

@SilvaMatteus do you have many mistakes? It compiles me but I have warnings. When I run AFL I have the error: no instrumentation detected. Have you experienced the same?

[SilvaMatteus]

Hi @21212124. It seems that you have the AFL compiled already. Could you share with me the steps you performed to compile? I think it's better to share via e-mail. matteus.sthefano.ls *AT* gmail.com

About your error: did you tried to run in dumb mode?

[21212124]

Hi @SilvaMatteus Any advance?

[SilvaMatteus]

Hi @21212124, I moved on to other priorities at the moment.

[SilvaMatteus]

Hi folks. I'm no longer working on this. Also, I do not have good news about these build instructions.

hello,there,When I used the .diff files in the patches in the directory,I found that it aserted a lot of error,so I just patch the files by hand (not by my computer) on my self.And then I debuged it,It seems work well！
