Software Install Problems

PostMon Nov 08, 2021 4:13 pm

I downloaded Blackmagic_Desktop_Video_Linux_11.0.tar.gz and tried to install the DesktopVideo deb file on a fresh installation of Ubuntu 18. That failed. The error message was:

Code: Select all
     dpkg -i desktopvideo_11.0a18_amd64.deb
    ....
    Failed to build driver(s)
    Possible causes:
     1. Driver is incompatible with your kernel version
     2. Kernel headers/gcc/make/etc. is not installed
     3. Kernel header version does not match the running kernel (5.4.0-89-generic)

The first few lines of the make.log file contains this
Code: Select all
    make[1]: Entering directory '/usr/src/linux-headers-5.4.0-89-generic'

Does anyone else have this problem? Does anyone know how I can resolve this?

Hello,
Upgrade Ubuntu 18 to Ubuntu 20.04 first !
Then check your kernel headers version. Or install those headers
Also check if gcc and make are installed and try again.
