Hi,

Im getting the following error:

[ 85%] Building CXX object source_subfolder/CMakeFiles/SQLiteCpp.dir/src/Transaction.cpp.o
/Users/paulo/.conan/data/sqlitecpp/3.1.1/_/_/build/518d5483cdb53cc130fd28cdad883cd2b4d0a54f/source_subfolder/src/Database.cpp:213:11: error: use of undeclared identifier
      'sqlite3_load_extension'
    ret = sqlite3_load_extension(getHandle(), apExtensionName, apEntryPointName, 0);
          ^

Can you help me?

Hi!
Thanks for reporting, though I don't see how that would be possible.
Nothing is ever removed in SQLite https://sqlite.org/changes.html

I suspect that you might be trying to link against à pre-built SQLite version were the extension mechanism is disabled.

Let me know

I revert it and i'm using version 2.5.0 and this problem don't happen.

[paulocoutinhox]

It only happen for iOS, because on other platform it don't happen.

If i change from:

self.requires("sqlitecpp/2.5.0")

to:

self.requires("sqlitecpp/3.1.1")

The error happen.

I checked now that it happen with sqlitecpp/2.5.0 too:
