Description Jonathan Ryshpan 2016-01-07 23:40:26 UTC

Description of problem:
Library files /usr/lib64/libusb-1.0.so  and /usr/lib64/libssl.so are missing from the Fedora-23 distribution.  


Version-Release number of selected component (if applicable):
RPMs libusbx-1.0.20-1.fc23.x86_64 and openssl-libs-1.0.2e-3.fc23.x86_64


How reproducible:
Always


Steps to Reproduce:
1. Link anything needing to -lusb-1.0 or -lssl


Actual results:
Link fails


Expected results:
Link succeeds


Additional info:
Cured on my system by
   # cd /usr/lib64
   # ln -s libusb-1.0.so.0.1.0 libusb-1.0.so
   # ln -s libssl.so.1.0.2e libssl.so

They are not missing you just need to install the right -devel packages to get them:

[hans@shalem llvm]$ rpm -qf /usr/lib64/libusb-1.0.so /usr/lib64/libssl.so
libusbx-devel-1.0.20-1.fc23.x86_64
openssl-devel-1.0.2e-3.fc23.x86_64

So "dnf install libusbx-devel openssl-devel" should fix this for you.

Regards,

Hans

Quite right, and since I was developing I should have thought to install these packages.  

Nevertheless it seems odd that libusbx contains 
  /usr/lib64/libusb-1.0.so.0
  /usr/lib64/libusb-1.0.so.0.1.0
while libusbx-devel contains
  /usr/lib64/libusb-1.0.so

and similarly openssl-libs contains
  /usr/lib64/libssl.so.1.0.2e
  /usr/lib64/libssl.so.10
while openssl-libs contains
  /usr/lib64/libssl.so

Is there a reason for this, or is it just the way things are?

The .so symlinks are only needed to link a binary while building it, where as the foo.so.x symlink is actually used to resolve runtime linking.

Since the .so is only used for compiling it goes in to the -devel pkg together with e.g. the .h and .pc files.

I learn a little every day.
