Jailhouse Compile Error

[Majidbahmani]

Hi,

Hope you are all doing well.

I have bitbaked "nxp-image-real-time-edge" yocto project for IMX8MP. and build Jailhouse repository by devtool. However, when I compile the Jaihouse, I get the following error:

xxx@LinuxForiMX:~/nxp/Repositories/Jailhouse/imx-jailhouse$ make
warning: the compiler differs from the one used to build the kernel

Does anyone know how to resolve this error?

Thank you

Hello,

This t’s a compilation error. Take a look here: Warning Options (Using the GNU Compiler Collection (GCC)) 4 for what array-bounds implies.

Can you tell us what compilation flags you are using? It should be a warning but you’ve got some flags enabled that convert warnings to errors (-Werror etc.)

regards

Thank you for your reply.

I found and commented "-Werror" in tools/Makefile 

```

KBUILD_CFLAGS := -g -O3 -DLIBEXECDIR=\"$(libexecdir)\" \

-Wall -Wextra -Wmissing-declarations -Wmissing-prototypes \ # -Werror \

-D__LINUX_COMPILER_TYPES_H \

-DJAILHOUSE_VERSION=\"$(shell cat $(src)/../VERSION)\" $(EXTRA_CFLAGS)

```

But now I get another error:

```
