libhid is dead

[NoraCodes]

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

I had the same issue as your. If you follow this thread you should be able to get it working ok. https://github.com/kost/dcled/issues/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.

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 :(

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

[Sagestum]

Yeah: `:~/dcled$ cmake . -- The C compiler identification is GNU 9.3.0 -- The CXX compiler identification is GNU 9.3.0 -- Check for working C compiler: /usr/bin/cc -- Check for working C compiler: /usr/bin/cc -- works -- Detecting C compiler ABI info -- Detecting C compiler ABI info - done -- Detecting C compile features -- Detecting C compile features - done -- Check for working CXX compiler: /usr/bin/c++ -- Check for working CXX compiler: /usr/bin/c++ -- works -- Detecting CXX compiler ABI info -- Detecting CXX compiler ABI info - done -- Detecting CXX compile features -- Detecting CXX compile features - done CMake Error at /usr/share/cmake-3.16/Modules/FindPackageHandleStandardArgs.cmake:146 (message): Could NOT find LibHIDAPI (missing: LIBHIDAPI_LIBRARY) Call Stack (most recent call first): /usr/share/cmake-3.16/Modules/FindPackageHandleStandardArgs.cmake:393 (_FPHSA_FAILURE_MESSAGE) cmake/FindLibHIDAPI.cmake:25 (FIND_PACKAGE_HANDLE_STANDARD_ARGS) CMakeLists.txt:13 (find_package)

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:

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-dev: /usr/lib/aarch64-linux-gnu/libhidapi-hidraw.a libhidapi-dev: /usr/lib/aarch64-linux-gnu/libhidapi-hidraw.so libhidapi-dev: /usr/lib/aarch64-linux-gnu/libhidapi-libusb.a libhidapi-dev: /usr/lib/aarch64-linux-gnu/libhidapi-libusb.so libhidapi-dev: /usr/share/doc/libhidapi-dev/AUTHORS.txt libhidapi-dev: /usr/share/doc/libhidapi-dev/README.md.gz libhidapi-dev: /usr/share/doc/libhidapi-dev/changelog.Debian.gz libhidapi-dev: /usr/share/doc/libhidapi-dev/copyright libhidapi-hidraw0: /usr/lib/aarch64-linux-gnu/libhidapi-hidraw.so.0 libhidapi-hidraw0: /usr/lib/aarch64-linux-gnu/libhidapi-hidraw.so.0.0.0 libhidapi-hidraw0: /usr/share/doc/libhidapi-hidraw0/changelog.Debian.gz libhidapi-hidraw0: /usr/share/doc/libhidapi-hidraw0/copyright libhidapi-libusb0: /usr/lib/aarch64-linux-gnu/libhidapi-libusb.so.0 libhidapi-libusb0: /usr/lib/aarch64-linux-gnu/libhidapi-libusb.so.0.0.0 libhidapi-libusb0: /usr/share/doc/libhidapi-libusb0/changelog.Debian.gz 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.

[fkrauthan]

Ok that error is now fixed as well. I've tested it inside a docker container but assume on a real linux system it will work too.

[Sagestum]

Yes it is working again, thanks :D. I hope it will lasts another 10 years 👍
