Description
I'm trying to test krabs by following instruction.
https://github.com/ellbrid/krabs/blob/master/docs/linux-image-setup-64.md
But I've got the following error.

Question
Does anyone have knowledge about the error message?
Your compiler probably does not supports those clang flags and it cause fatal issues like this.
I think this issue can be solved by using clang as the default compiler instead of gcc.
$ sudo apt install -y clang
$ sudo update-alternatives --config cc
There are 2 choices for the alternative cc (providing /usr/bin/cc).
Selection Path Priority Status
------------------------------------------------------------
* 0 /usr/bin/gcc 20 auto mode
1 /usr/bin/clang 10 manual mode
2 /usr/bin/gcc 20 manual mode
Press <enter> to keep the current choice[*], or type selection number: 1
update-alternatives: using /usr/bin/clang to provide /usr/bin/cc (cc) in manual mode=> Select 1
Can you check if the above works?
As you said, I can build it successfully by switching cc compiler from gcc to clang!
Thanks!
It seems that the build script can handle this issue without installing clang.
If the issue persists, please reopen.
Thank you for your quick fix.
At once, I've tried it with new commit ( 593bb96 ).
I could've built it successfully, but I've got the following error in boot step:
Booting from Hard Disk...
Stage1: I/O error
I don't know whether the fix is related to the boot failure.
Do you have any ideas?
