Hi all,
I am seeking some help trying to build the ethercat master on Alma9. I am
trying to first just build the simplest configuration I can (i.e. not an RT
kernel), on a VMWare VM (not sure if this will create a problem). I have
installed kernel-devel and it looks like I have the kernel sources in
/usr/src/kernels/5.14.0-427.37.1.el9_4.x86_64
uname -srvmpio
Linux 5.14.0-362.24.2.el9_3.x86_64 #1 SMP PREEMPT_DYNAMIC Sat Mar 30 14:11:54
EDT 2024 x86_64 x86_64 x86_64 GNU/Linux
Following the instructions:
./bootstrap
./configure
--with-linux-dir=/usr/src/kernels/5.14.0-427.37.1.el9_4.x86_64 --enable-generic
make
make modules
The build fails with:
