dnf search linput and dnf search lgbm don't yield any results. How can I get these in Fedora?

Edit: Backstory

I'm trying to build a Rust program, but it won't compile because apparently I'm missing some things. It said:

 = note: /usr/bin/ld: cannot find -lxkbcommon
 /usr/bin/ld: cannot find -lxkbcommon
 /usr/bin/ld: cannot find -linput
 /usr/bin/ld: cannot find -lgbm
 collect2: error: ld returned 1 exit status

I installed libxkbcommon via dnf install libxkbcommon-devel and then the output looked like this:

 = note: /usr/bin/ld: cannot find -linput
 /usr/bin/ld: cannot find -lgbm
 collect2: error: ld returned 1 exit status

So I figured I needed something called linput and lgbm as well, only I cannot find those with dnf search and I'm coming up empty-handed with google, hence the question! Guess I'm so new at Linux I didn't realize a backstory would be necessary for this. Now that I've supplied one, I wonder if that downvote could be reversed?

What you are getting are error messages from the linker (ld), which is complaining that the libraries you are looking for are not available.

A message such as /usr/bin/ld: cannot find -linput actually means it was looking for a file named libinput.so. The -l flag is a command-line argument (to ld or to gcc) that expects the library name to follow and then the library name is used to form the file name which includes the lib prefix and the .so suffix (for dynamically loadable library, which is what is typically used in most distributions, Fedora included.)

So it turns out that the files you need are libinput.so and libgbm.so.

You can then use dnf provides to search for those files. Assuming you're using a 64-bit distribution, these libraries would be in /usr/lib64, so the full commands would be:

$ dnf provides /usr/lib64/libinput.so
libinput-devel-1.12.6-3.fc30.x86_64 : Development files for libinput
Repo : rawhide
Matched from:
Filename : /usr/lib64/libinput.so

$ dnf provides /usr/lib64/libgbm.so
mesa-libgbm-devel-19.0.0~rc7-1.fc30.x86_64 : Mesa libgbm development package
Repo : rawhide
Matched from:
Filename : /usr/lib64/libgbm.so

If you don't know the exact directory, you can also use dnf provides '*/libinput.so' or other wildcards if you know even less information about the files you want to search (and are willing to sort through more search results in look for something useful.)

In your case, it seems what you need is to:

$ sudo dnf install libinput-devel mesa-libgbm-devel

From that point on, dnf should also bring all other dependencies you need. Hopefully this is all you're missing to build the software you're building. But if you have further issues of missing libraries, using this information you might be able to find packages that ship those, assuming they're available in Fedora.

If this is the same thing I found related to this:

https://lightgbm.readthedocs.io/en/latest/Installation-Guide.html

lightGBM is a gradient boosting framework that uses tree-based learning algorithms. It is designed to be distributed and efficient with the following advantages:

• Faster training speed and higher efficiency.


• Lower memory usage.


• Better accuracy.


• Support of parallel and GPU learning.


• Capable of handling large-scale data.

On Linux LightGBM can be built using CMake and gcc or Clang.

Install CMake.

Run the following commands:

git clone --recursive https://github.com/Microsoft/LightGBM ; cd LightGBM
mkdir build ; cd build
cmake ..
make -j4
