RHEL 9.4 custom kernel (5.14.0-427.37.1.el9_4.x86_64)

Posted on

Hi everybody,

I'm currently searching someone to help me to build a custom kernel for RHEL 9.4. (

I need to had LEGACY98_PTY support to this kernel.

I'm used to do this operation on other Operating System like Ubuntu,
or OpenSuse, but impossible to do that on RHEL 9.4 with a 5.14.0-427.13.1.el9_4 kernel.

What I'm tried :

Create an ESXI VM with RHEL 9.4
Install build essentials packages.
Install kernel-devel package.
Install kernel-headers package.
Get and copy current .config file in src folder.
make menuconfig
Add legaty_pty and set pty number.
Save .config file.
make => issue when try to build tools/objtools folder.

make -C /usr/src/kernels/5.14.0-427.37.1.el9_4.x86_64/tools/build CFLAGS= LDFLAGS= fixdep
make[1] : on entre dans le répertoire « /usr/src/kernels/5.14.0-427.37.1.el9_4.x86_64/tools/build »
make[1] : on quitte le répertoire « /usr/src/kernels/5.14.0-427.37.1.el9_4.x86_64/tools/build »

make: *** [Makefile:53 : objtool-in.o] Erreur 1

Many thanks for your help.

Fabe.
