linux- last make -j4 error about satdump HOT 3 CLOSED

Hi, at first sight is appears you simply did not run a valid cmake command. It should be cmake -DCMAKE_BUILD_TYPE=Release .. at least. Maybe you copied the end of the line even though it's actually longer in the README?
make -j4 returning that result definitely confirms CMake failed to properly generate build files.

thank you for responding to my inquiry, i deeply appreciate it. i tried your advice and i got a different error from the cmake command: cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=/usr .. i also tried cmake -DCMAKE_BUILD_TYPE=Release ..
here is the return message from both of them:
_INSTALL_PREFIX=/usr ..

To me, it appears like you just need to install dependencies, such as libvolk2-dev or libvolk1-dev, and libjpeg-dev.
