Daphne install error

[spanishsnowman]

I've seen the posts from the same error back from 2016, but nothing is recent.
I'm getting the error when installing from the Optional Packages.

When I install I get an error: Could not successfully install Daphne - laser disc Emulator (/home/pi/Retropie-Setup/tmp/build/daphne/daphne.bin not found).

I managed to figure out how to view the log file and I see one or two errors.
It goes through the "Building 'daphne' : Daphne - Liserdisc Emulator"

I see the following:
make[1]: Entering directory ' /home/pi/RetroPie-Setup/tmp/build/daphne/src/ldp-out'
g++ -c sony.cpp -o sony.o
In file included from sony.h:29:0,

compilation terminated.

Makefile:70: recipe for target 'sub' failed
make: *** [sub] Error 2

/hom/pi/RetroPie-Setup/tmp/build/daphne /home/pi

I don't know how to load/transfer the log file for review. I found manual install instructions and they fail too.

Please do not post a support request without first reading and following the advice in https://retropie.org.uk/forum/topic/3/read-this-first

You need to provide details of your set up. The error is due to missing SDL headers. Without knowing what you're running on and retropie version etc, it's impossible to advise.

Also please upload a full build log to a pastebin site. Logs can be found in the logs folder under RetroPie-Setup
