I am trying to compile a ODBC software with the unix-odbc library which I installed with the following command on Ubuntu 16.04. 

apt-get install unixodbc-dev unixodbc-bin unixodbc

The library worked fine until I tried to call SQLCancelHandle in my software. And I started to get:

error: undefined reference to 'SQLCancelHandle'

After investigation, I realized that in sql.h the function was defined in the package. (call with the wrong parameters issue into an error of compilation complaining about the parameters)

My conclusion is the shared library associated with doesn't implement the function.

Question: Where am I supposed to put issue about Ubuntu packages? Is it possible to suggest a fix?

    You can file a bug report. You should completely describe the problem. Though you shouldn't only give your analysis of what caused it and your fix, you can definitely include a fix, or suggest how it should be fixed, or both, in your bug report. We also have How do I report a bug? I don't think you really need any more specific information than those resources give, but if you do, please clarify (you should [edit], and feel free also to comment with @EliahKagan in the comment, which will ping me). – Eliah Kagan Apr 20 '18 at 14:33
  • @EliahKagan Thanks for your help. I can't report as a bug as it is a -dev package. But I will try the newest .deb file to verify the bug has been corrected and suggest an update for the package. – Brighter side Apr 20 '18 at 15:03

    You can report bugs in software provided by -dev packages. Bugs are reported against source packages. A source package typically has at least one associated binary package, but often has more than one. Even -dev packages that don't provide "binaries" are still binary packages in this sense, and the unixodbc-dev binary package is built from the unixodbc source package. You can therefore report the bug against unixodbc in Ubuntu, if it is present in the unixodbc-dev binary package. – Eliah Kagan Apr 20 '18 at 15:10

    You can even use ubuntu-bug with -dev packages: ubuntu-bug unixodbc-dev. Apport collects details and gives you a browser tab, which turns to a page where you can report the bug. Can you [edit] your question with the info from your comment about not being able to report against a -dev package? That's different enough from the linked question that I think this isn't really a dupe. Then we can reopen this and I (or someone else if they do it first) can post an answer. – Eliah Kagan Apr 20 '18 at 15:39
