@reyalpYes , lua needs readline , chdkptp needs readline.Since lua is probably installed on the system , the only readline request comes from chdkptp.
It asks for "readline.so.6" so i believe it means readline6.Linking that lib to version 7 of the system is something i try to avoid doing.
Usually i can find version 6 in most of the distros...but the feeling is that is getting old.No biggie , just saying.
Same exactly thing applies for libusb , but i can understand that this "thing" is more difficult to change into the program...
Just keep them in mind , if you intent on working on chdkptp since there will be no point on upgrading it and it could not work because of incompatibilities..
Confirming that chdkptp works if i comment out that line.I noticed that the pull down menu were we see the connected cameras is disabled..no big deal for me..never use it.
Dont know where else has impact to be honest...
