It's very simple:
(1) First, you need to identify the chipset architecture (mipsel, arm, aarch64, sh4) used in your device
(2) You need to consider whether Softcam will work on an older Enigma2 (like your Blackhole 3.x.x)
- in case the latest version of Softcam does not work, then you will have to use old versions of Softcam, which may not have all the features!
- alternatively you can try to create symbolic library links - from new libraries required by Softcam to old libraries in the system ... you can also get and upload missing libraries from the Internet, but the compatibility of functional Softcam is not guaranteed at all!
(3) You must also keep in mind that each Enigma2 can use a different type of Softcam startup ... so the best method to install Softcam is to use a manual procedure instead of using an automated IPK / DEB installation package
