Hey Y'all,
I'm trying to write a simple utility class to read rows from a SQLite3
database using compile time parameters, but I've run into a weird problem.
https://pastebin.com/eTnbRjEd
If I try to instantiate a Reader class I'm hitting a linker error saying
Error 42: Symbol Undefined _sqlite3_open
But if I change the Reader definition to include a dummy template
argument and instantiate it with any dummy type argument, the code
compiles ok. Am I missing something?
It isn't template instantiation error. Undefined symbol means you need
link your executable with some library that contains this undefined
symbol. In your case you need to link to libsqlite.so (linux) or
sqlite.dll (windows).
