3 years ago Hello Arulpandiyan,
I'd suggest to move this discussion to cip-dev@lists.cip-project.org or isar-users@googlegroups.com. IIUC, classmap.h is an internal header not intended for user space, so I suppose we shouldn't add it to linux-headers. If you build genheaders from within the kernel source tree, the error should not happen:
wget https://mirrors.edge.kernel.org/pub/linux/kernel/v4.x/linux-4.19.165.tar.gz
tar zxf linux-4.19.165.tar.gz
cd linux-4.19.165
make defconfig
make scripts; echo $?
HOSTCC scripts/selinux/genheaders/genheaders
0I don't know what is inside linux-headers-4.19.165-cip41-rt18+mel6, but the "headers" part doesn't sound right. Maybe you could share how the problem could be reproduced.

Hello Ismagulb
We had a requirement to build the kernel scripts on the target itself where we don't have a kernel directory and only have /usr/src/linux-headers-${uname -r} directory. Also note that SELINUX is enabled in 4.19.165-cip41-rt18+mel6 kernel.root@iot2050:/usr/src/linux-headers-4.19.165-cip41-rt18+mel6# make scripts

Closing this PR, As per the standard procedures, we should not expose kernel headers. Hence updated the document to rebuild the kernel header from source code https://confluence.alm.mentorg.com/display/PS/Omni-2.2+Recompile+Headers+Scripts
Copy the selinux headers, as it is required to build scripts on target
