libhid is dead

[NoraCodes]

libHID is dead and, since 10.10, cannot be installed in Ubuntu. Please update to use libhidapi.

[andrew-codechimp]

I had the same issue as your. If you follow this thread you should be able to get it working ok.
#1

[fkrauthan]

I did do a test upgrade to libhidapi that at least on mac os works. I also upgraded the build system to CMake. If the repo owner is interest I can submit a pull request.

[kost]

Submit pull request!

[fkrauthan]

Take a look at #4 for the code changes. I did not adjust the READMEs but should be pretty self explanatory.

[Sagestum]

Does not work for me on Ubuntu 20.04.3 LTS or Debian Buster on the Raspberry PI. I have installed the
'apt-get install libhid-dev'
but it says it is not installed :(

gcc -c -g -O3 -DFONTDIR='"/usr/local/share/dcled"' -DDCLEDVERSION='"2.0"' dcled.c dcled.c:28:10: fatal error: hidapi.h: Datei oder Verzeichnis nicht gefunden 28 | #include <hidapi.h> | ^~~~~~~~~~ compilation terminated. make: *** [makefile:64: dcled.o] Fehler 1

[fkrauthan]

@Sagestum did you use cmake? It should actually throw an error in case it couldn't find hidapi?

[Sagestum]

Yeah:

Maybe I have forgotten somethin importend, my build skills are very poor.

libhid is not the same as libhidapi. You need to install libhidapi-dev

[Sagestum]

libhidapi-dev is installed:

~/dcled$ sudo apt install libhidapi-dev [sudo] Passwort für parallels: Paketlisten werden gelesen... Fertig Abhängigkeitsbaum wird aufgebaut. Statusinformationen werden eingelesen.... Fertig libhidapi-dev ist schon die neueste Version (0.9.0+dfsg-1).

but still:

You probably have to figure out how you can tell cmake where it is installed as it claims that this library can't be found. I think by default the file should be in /usr/include/hidapi/hidapi.h.

[Sagestum]

Yes, I can confirm that the file is there. /usr/include/hidapi/hidapi.h
But I have no clue how to tell it where it is

[fkrauthan]

Try to run find /usr/lib -name "libhidapi.a" to see where it stored the lib file. That seem to be the file it can not find in your case.

[Sagestum]

This file could not be found. I have search the complete disk, but nothing. I have startet to search via apt-file, but it could find it.

But:

~/dcled$ sudo apt-file search libhidapi

libhidapi-libusb0: /usr/share/doc/libhidapi-libusb0/copyright

Maybe the file was renamed?

[fkrauthan]

Ah ok can you use my latest commit. I modified the cmake scripts a bit which might fix the issue you have.

[Sagestum]

cmake now runs, but sadly make fails.
