Linux installation related

[ullaskrakon]

Good day!

New to time card, and wanted help with the following

I was following the installation instructions with Linux and got into the following:

sudo ./remake
Could not locate kernel source for distribution 'ubuntu'

So I tried

make -C /usr/src/linux-headers-$(uname -r) M=$(pwd) modules
make: Entering directory '/usr/src/linux-headers-6.11.0-29-generic'
warning: the compiler differs from the one used to build the kernel

Any help appreciated. Thanks.

The compilation errors are fixed in #121

The remake script can be fixed with the following patch:

 case "$DIST" in
     debian*|ubuntu)
-        KDIR=/usr/src/linux-${KVER}
+        KDIR=/usr/src/linux-headers-${KVER}
         ;;
     centos*)
         KDIR=/usr/src/kernels/${KVER}

Also, unless you have specific reasons to use this out-of-tree driver, i'd recommend you to use the in-tree one: https://github.com/torvalds/linux/blob/master/drivers/ptp/ptp_ocp.c, installed by default on ubuntu (verify it is present with lsmod | grep ocp)
